Ezetimibe (eh-HIHI-firri-ibe)
Brand Name Zetia
Combination Product
Generic Ingredients: Ezetimibe + Simvastatin Vytorin
Type of Drug
Cholesterol - lowering agent.
Prescribed For
High cholesterol, high LDL (”bad”) cholesterol, high triglycerides, and low HDL (”good”) cholesterol; also prescribed for two rare genetic disorders called homozygous familial hypercholesterolemia and homozygous sitosterolemia.
General Information
Unlike statin drugs, ezetimibe interferes with the absorption of cholesterol through the intestine and into the bloodstream. Ezetimibe may be helpful for people whose LDL (”bad”) cholesterol remains high despite treatment with a statin drug. Cholesterol-lowering medicines should always be used together with appropriate diet and exercise.
Ezetimibe may be taken alone but is often taken in combination with a statin drug (generally simvastatin). Vytorin is a brand-name combination of these 2 medications. See Stalin Cholesterol-Lowering Agents, page 1052.
Cautions and Warnings
Do not take this drug if you are allergic or sensitive to any of its ingredients.
People with liver disease or elevated liver enzyme measurements should not take ezetimibe because its effects on the liver are not known.
Ezetimibe does not slow hardening of the arteries.
There may be a risk of myopathy (skeletal muscle disorder) with ezetimibe; contact your doctor if you experience any unexplained muscle pain, tenderness, or weakness. Ezetimibe + simvastatin has the same effect as simvastatin alone; see Statin Cholesterol-Lowering Agents, page 1052.
Possible Side Effects
Ezetimibe side effects are similar to those reported by people taking a placebo (sugar pill).
V Most common: headache, back pain, joint pain, and abdominal pain.
C,Ibmrnon: muscle ache and respiratory infection.
V Less common: fatigue, chest pain, diarrhea, sore throat, and cough.
For additional information about ezetimibe + simvastatin, see Statin Cholesterol- Lowering Agents, page 1052.
Drug Interactions
• Cholestyramine reduces the amount of ezetimibe absorbed
in the blood. Separate these drugs by 2 hours or more.
• Cyclosporine (to prevent organ transplant rejection) may substantially increase the amount of ezetimibe in the blood. This combination must be monitored closely by your doctor.
• Gemfibrozil (another blood-fat reducer) can increase the amount of ezetimibe in the blood.
• Fenofibrate may increase the effects of ezetimibe. Fibrates
other than fenofibrate should not be used with ezetimibe due to
the risk of gallbladder complications. For additional informa-
tion about ezetimibe + simvastatin, see Statin Cholesterol-
Lowering Agents, page 1052.
Food Interactions
This drug can be taken without regard to food or meals.
Usual Dose
Ezetimibe
Adult and Child (age 10 and over): 10 mg once a day. Child (age 9 and under): not recommended.
Ezetimibe + Simvastatin
Adult: 10 mg ezetimibe plus 10-80 mg simvastatin once a day in the evening. The simavastatin dose depends on individual need.
Overdosage
Little is known about the effects of ezetimibe overdose. Call your local poison control center or a hospital emergency room for information. If you seek treatment, ALWAYS bring the prescription bottle or container.
Special Information
If you are taking more than one drug to lower cholesterol or another blood fat, consider the side effects of all of those drugs combined.
,S’D'L’6a) Populations
Pregnancy/Breast-feeding: Little is known about the effects of ezetimibe during pregnancy. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks. Statin drugs should never be taken by a pregnant woman or nursing mother.
It is not known if ezetimibe passes into breast milk. Nursing mothers who must take it should use infant formula.
Seniors: Seniors may use this drug without special precaution.
Generic Name
Famciclovir (fam-SYE-kloe-vere)
Brand Name Famvir
Type of Drug Antiviral.
Prescribed For
Herpes zoster (shingles), genital herpes, herpes labilalis (cold sores), and herpes simplex in HIV-infected people.
General Information
Famciclovir is absorbed into the body and converted to the antiviral penciclovir, the drug that actually works against shingles by interfering with the reproduction of DNA in the herpes virus. Famciclovir does not affect DNA in uninfected body cells. Famciclovir is broken down by the liver and eliminated from the body through the kidneys.
Cautions and Warnings
Do not take famiciclovir if you are allergic or sensitive to any of its ingredients.
Those with reduced kidney function should have their dosage adjusted accordingly.
Severe liver disease reduces the maximum possible concentration of Famciclovir in the blood and increases the time it takes to reach this maximum level; however, dosage adjustment is not normally required.
Possible Side Effer.%
♦ Most common: headache, nausea, and diarrhea.
♦ Less common: fever, fatigue, pain, vomiting, constipation, appetite loss, dizziness, tingling in the hands or feet, sleepiness, sore throat, sinus irritation, itching, gas, dysmemorrhea, and signs of shingles.
Possible Side Effects (continued)
Rare: chills, abdominal pain, back or joint pain, and upset stomach. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Probenecid, cimetidine, and theophylline interfere with the elimination of famciclovir from the body, possibly leading to higher levels of famciclovir in the blood.
• People who took famciclovir and digoxin together experienced increased digoxin In their blood.
Food Interactions None known.
Usual Dose
Shingles
Adult (age 18 and over): 500 mg every 8 hours for 1 week. People with reduced kidney function may require a reduced dose taken as infrequently as once a day.
Genital Herpes
Adult (age 18 and over): 1000 mg twice daily for 1 day; or 250 mg twice a day for up to 1 year for suppression; or 250 mg 3 times a day for 7 days for initial episode. People with reduced kidney function take the same dose but less often, as infrequently as once every 2 days. HIV-infected people should take 500 mg twice a day for 7 days.
Cold Sores
Adult (age 18 and over): 1500 mg as a single dose. Initiate therapy at the earliest sign or symptom of a cold sore (tingling, itching, or burning).
Overdosage
Little is known about the effects of famciclovir ovecdose. Overdose victims should be %Mn to a hospital emergency room for treatment. ALWAYS bring the prescription bottle or container.
Special Information
Famciclovir treatment should be started as soon as shingles is diagnosed. For maximum benefit, be sure to complete the full week of treatment.
Famciclovir is not a cure for genital herpes and it is not known if it will prevent the transmission of the herpes virus to another person. Avoid sexual intercourse when herpes lesions are present even while taking famciclovir for genital herpes.
Begin taking famciclovir at the first sign of a herpes attack (symptoms include pain, tenderness, burning, itching, tingling, ulcers, or scabs). The effectiveness of starting famciclovir 6 hours or more after symptoms or lesions appear has not been established.
Call your doctor if you experience any unusual or intolerable side effects.
If you forget a dose of famciclovir, take it as soon as you remember. If it is almost time for your next dose, skip the dose you forgot. Do not take a double dose. Call your doctor if you forget more than 2 doses in a row.
Special Populations
Pregnancy/Breast-feeding: Famciclovir should only be taken by a pregnant woman if it is absolutely necessary and the possible benefits outweigh the risks to the fetus.
In animal studies, penciclovir (the active form of famciclovir) passed into breast milk in high concentrations but it is not known if this holds true for humans. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors clear famciclovir from the bloodstream more slowly than younger people and should have their dosage adjusted according to their level of kidney function.
Generic Name
Famotidine (fam-OE-tih-dine) 91
Brand Names
Fluxid Pepcid AC
Pepcid Pepcid Complete
Type of Drug Histamine H2 antagonist.
Prescribed For
Ulcers of the stomach and duodenum (upper intestine). This drug is also used to treat gastroesophageal reflux disease (GERD),
stress ulcer, and other conditions characterized by the production of large amounts of gastric fluids; to prevent stress ulcer and stomach and upper intestinal bleeding; and to stop the production of stomach acid during surgery. Pepcid AC is approved for heartburn.
General Information
Histamine H2 antagonists work by turning off the system that produces stomach acid and other secretions. Famotidine is effective in treating the symptoms of ulcer and preventing complications of the disease, although an ulcer that does not respond to another histamine H2 antagonist will probably not respond to famotidine. Histamine H2 antagonists differ only in their potency. Cimetidine is the least potent; 1000 mg are roughly equal to 300 mg of either nizatidine or ranitidine, or 40 mg of famotidine. All these drugs have roughly equivalent success rates in treating ulcer disease and comparable risk of side effects.
Cautions and Warnings
Do not take famotidine if you are allergic or sensitive to any of its ingredients or to any histamine H2 antagonist.
People with kidney or liver disease should take famotidine with caution because 1/3 of each dose is broken down in the liver and the rest passes out of the body through the kidneys.
Do not self-treat with over-the-counter (OTC) forms of famotidine without the advice and supervision of your doctor.
Possible Side Effects
✓ Most common: headache.
✓ Less common: dizziness, mild diarrhea, and constipation.
✓ Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• T-_Meat-coated tablets should not be taken with famotidine. The change in stomach acidity that famotidine produces causes the tablets to disintegrate prematurely in the stomach.
• Antacids, anticholinergics, and metoclopramide may slightly reduce the amount of famotidine absorbed into the blood. No special precaution is needed.
Food Interactions
Famotidine may be taken without regard to food or meals.
Usual Dose
Adult 20-40 mg at bedtime, or 20 mg twice a day for 4-8 weeks. Dosage should be reduced in people with severe kidney disease.
Child (age 1-16): 0.23-0.45 mg per lb. of body weight, at bedtime or in 2 divided doses, up to 40 mg a day.
Child (under age 1): Consult your doctor.
Over-the-counter forms of famotidine such as Pepcid AC or Pepcid Complete should only be used for the temporary relief of heartburn, and are not recommended for children under 12 years of age. Do not take more than 2 capsules or chewable tablets in 24 hours.
Overdosage
Little is known about the effects of famotidine overdose, but victims may experience exaggerated side effects. Your local poison control center may advise giving ipecac syrup—available at any pharmacy—to induce vomiting and remove any remaining drug from the stomach. Victims who have definite symptoms should be taken to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Take famotidine exactly as directed and follow your doctor’s instructions regarding diet and other treatment in order to get the maximum benefit from the drug. Antacids may be taken together with famotidine if needed.
Do not take the maximum dose continuously for more than 2 weeks without the consent and supervision of your doctor.
Cigarettes worsen stomach ulcers and may reduce famotidine’s effectiveness.
Call your doctor at once if you develop any unusual side eiiecls such as bleeding or bruising,’ iWness, diarrhea, dizziness, or rash. &’A&, tarry stools or vomiting material that resembles coffee grounds may indicate your ulcer is bleeding.
If you forget a dose of famotidine, take it as soon as you remember. If it is almost time for your next dose, skip the one you forgot and continue with your regular schedule. Do not take a double dose.
Special Populations revealed no Pregnancy/Breast-feeding: Although animal studies
damage to the fetus, famotidine should be avoided by women who are or might be pregnant. When this drug is considered crucial by your doctor, its possible benefits must be carefully weighed against
its risks.
Famotidine may pass into breast milk. Nursing mothers who
must take this drug should use infant formula.
Seniors: Seniors may need lower doses due to loss of kidney function and may be more susceptible to side effects.
Generic Name
Felbamate (FEL-bam-ate)
Brand Name Felbatol
Type of Drug Anticonvulsant.
Prescribed For
Partial seizures and Lennox-Gastaut syndrome in children.
General Information
Felbamate is related to the older sedative meprobamate. Exactly how felbamate works is not known, but it raises the seizure threshold and prevents the seizure impulse from spreading in the brain, as do other anticonvulsants. Felbamate should only be used when other seizure drugs have failed because of the risks associated with it. About half of each dose passes out of the body through the kidneys; the other half is broken down and eliminated by the liver.
Cautions and Warnings
Do not take felbamate if you am allergic or sensitive to any of its ‘Irigredlents or to any related drugs such as meprobamate.
Felbamate is associated with an increase in the risk of aplastic anemia, a potentially fatal condition.
Possibly fatal liver failure occurs in people taking felbamate much more often than normal. Regular liver function tests are recommended. People with liver disease should not take felbamate.
Felbamate is not recommended as first-line epilepsy treatment. Felbamate should be used only by those with severe epilepsy for whom the benefits outweigh the risks. Doctors prescribing felbamate should be thoroughly familiar with the drug and must obtain written, informed consent from patients before prescribing.
Felbamate should never be suddenly stopped or seizures may become more frequent. Dosage should be gradually reduced or replaced by another anticonvulsant.
Felbamate may cause increased sensitivity to the sun. Wear protective clothing and use sunscreen while taking this drug. People with kidney disease may require lower doses.
Possible Side Effects
Adult
♦ Most common: sleeplessness, sleepiness, fatigue, headache, dizziness, nervousness, upset stomach, vomiting, constipation, nausea, and appetite loss.
V Common: anxiety, tremors, walking unusually, depression, tingling in the hands or feet, diarrhea, liver inflammation, abdominal pains, respiratory infections, abnormal vision, and taste changes.
✓ Less common: weakness, dry mouth, stupor, abnormal thinking, rash, sinus irritation, sore throat, muscle aches, fever, and chest pain.
♦ Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Child
✓ Most common: abdominal pain, fever, respiratory infections, sleeplessness, sleepiness, nervousness, vomiting, constipation, and black-and-blue marks.
✓ Common: headache, appetite loss, hiccups, sore throat, coughing, middle ear infections, fatigue, weight loss, temporary loss of urine control, qak”,,NbNW)ng unusually, weak-))855, abnormal thinking, emotional instability, pinpoint pupils, rash, upset stomach, and low white-blood-cell count.
✓ Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if your child experiences any side effect not listed above.
Drug Interactions
• Combining felbamate and other antiseizure drugs usually requires dosage adjustments due to the risk of drug interaction. Dosage of felbamate should be reduced by 20-33% to reduce the risks of associated side effects.
• Combining felbamate and carbamazepine reduces blood levels of both drugs by roughly half. Dosage adjustments are necessary.
• Combining phenobarbital and felbamate increases the amount of phenobarbital in the blood and decreases felbamate levels. Dosage adjustments are necessary.
• If you combine felbamate and phenytoin, your phenytoin dosage may have to be reduced by as much as 40%. This combination also decreases felbamate blood levels by almost 50%.
• Felbamate increases blood levels of valproic acid and methsuximide.
Food Interactions
Felbamate is best taken on an empty stomach but may be taken with food if it causes upset stomach.
Usual Dose
Adult and Child (age 14 and over): 1200-3600 mg a day, divided into 3-4 doses.
Child (age 2-13): 6.8-20.5 mg per lb. a day, divided into 3-4 doses.
Overdosage
Overdose symptoms may include upset stomach, increased heart rate, and felbamate side effects. Call your local poison control center or a hospital emergency room for more information. If you seek treatment, ALWAYS bring the prescription bottle or container.
Special Information
Do not take more felbamate than your doctor has prescribed. Felbamate can cause drowsiness; be careful when, driving perfQ(ft g
Avoid prolonged exposure to the sun while taking felbamate. Call your doctor if you develop any bothersome or persistent side effect.
Maintain good dental hygiene while taking felbamate and use extra care when brushing or flossing because this drug can cause swollen gums. See your dentist regularly.

Generic Name
Felodipine (feh-LOE-dih-pene) 91
Brand Name Plendil
Combination Product
Generic Ingredients: Enalapril + Felodipine Lexxel
Type of Drug
Calcium channel blocker.
Prescribed For High blood pressure.
General Information
Felodipine is one of many calcium channel blockers available in the U.S. Its once-daily dosage schedule makes it particularly stilted to treating high blood Felodipine blocks the passage of calcium, an essential factor in muscle contraction, into the heart and smooth muscles. Such blockage interferes with the contraction of these muscles, which in turn dilates (widens) the veins and vessels that supply blood to them. This dilating effect reduces blood pressure, the amount of oxygen used by the heart muscle, and the risk of blood vessel spasm. Felodipine is therefore useful in
treating not only high blood pressure but also angina pectoris (brief attacks of chest pain), a condition related to poor oxygen supply
to the heart muscles.
Felodipine only affects the movement of calcium into muscle cells-, it has no effect on calcium in the blood.
Lexxel is a combination of felodipine and enalapril, an angiotensin converting enzyme (ACE) inhibitor.
Cautions and Warnings
Do not take felodipine if you are allergic or sensitive to any of its ingredients.
On rare occasions, felodipine may cause very low blood pressure that may lead to stimulation of the heart and rapid heartbeat and can worsen angina. This reaction may happen when treatment is first started, when dosage is increased, or if the drug is rapidly withdrawn; it may be avoided by reducing dosage gradually.
Studies have shown that people taking calcium channel blockers—usually those taken several times a day, not those taken only once daily—have a greater chance of having a heart attack than do people taking beta blockers or other medications for the same purpose. Discuss this with your doctor to be sure you are receiving the best possible treatment.
Patients taking a beta-blocking drug who begin taking felodipine may develop heart failure or increased angina.
People with severe liver disease may require dosage adjustments.
People taking felodipine who have had a heart attack and have lung congestion may experience worsened heart failure, since this drug can actually reduce the force of each heartbeat.
Possible Side Effects
Side effects produced by calcium channel blockers are generally mild and rarely cause people to stop taking them. Side effects are more common with higher doses and in older patients.
I Most common: swelling in the ankles, feet, or legs; dizziness; lightheadedness; muscle weakness or cramps; facial flushing; and headache.
V Less common: respiratory infections, cough, tingling in the hands or feet, upset stomach, abdominal pains, chest pains,
stomach, , heart palpitations,
Drug Interactions
• Felodipine may increase the amount of beta-blocking drugs in the bloodstream. This can lead to heart failure, very low blood pressure, or an increased incidence of angina. However, in many cases these drugs have been taken together with no problem.
• Felodipine increases the effects of other blood-pressurelowering drugs. Such drug combinations are often used to treat hypertension.
• Cimetidine, ranitidine, and azole antifungals such as ketoconazole and itraconazole increase the amount of felodipine in the blood and may account for a slight increase in the drug’s effect.
• Phenytoin and other hydantoin antiseizure medicines, carbamazepine, and barbiturate sleeping pills and sedatives may decrease the amount of felodipine in the blood, reducing its effect on the body.
• Erythromycin and cyclosporine may increase the side effects of felodipine.
• Felodipine may increase the effects of digoxin, theophylline (prescribed for asthma and other respiratory problems), and oral anticoagulant (blood-thinning) drugs.
• Felodipine may also interact with quinidine (prescribed for abnormal heart rhythm) to produce low blood pressure, very slow heart rate, abnormal heart rhythms, and swelling in the arms or legs.
• Qd(Gii= Channel blockers may cause bleeding when taken alone or combined with aspirin.
Food Interactions
You may take felodipine with food if it upsets your stomach. Avoid taking felodipine with grapefruit juice—it doubles the amount of drug absorbed.
Possible Side Effects (continued) nausea, constipation, diarrhea
throat, runny nose, back pain, rash.
and
♦ Rare: Rare side effects can affect the heart,
blood, and joints. It can affect and
your mood, sex drive,
urinary tract. Contact your do you experience side effect not listed above.
ctor if any Usual Dose
2.5-10 mg a day. No patient should take more than 20 mg a day. Do not stop taking felodipine abruptly. The dosage should be reduced gradually over a period of time.
Overdosage
Felodipine overdose can cause low blood pressure. If you think you have taken an overdose of felodipine, call your doctor or go to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Call your doctor if you develop constipation, nausea, very low blood pressure, breathing difficulties, increased heart pain, dizziness, or lightheadedness, or if other side effects are bothersome or persistent.
Swelling of the hands or feet may develop within 2 or 3 weeks of starting felodipine. The chances of this happening depend on age and dosage. It occurs in less than 10% of people under age 50 taking 5 mg a day and in more than 30% of those over age 60 taking 20 mg a day.
Be sure to continue taking your medication even if you feel well, and follow any instructions for diet restriction or other treatments to help maintain lower blood pressure.
Do not break or crush felodipine tablets.
It is important to maintain good dental hygiene while taking felodipine and to use extra care when using your toothbrush or dental floss because of the chance that the drug will make you more susceptible to certain infections.
If you forget to take a dose of felodipine, take it as soon as you remember. If it is almost time for your next dose, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
Special Populations
Pregnancy1filreast-feeding. Animal studies of felodipk”e have shown that it crosses RAW the Zeta) circulation and causes birth iNlfEcls. Women who are or who might become pregnant while taking this drug should not take it without their doctor’s approval. The potential benefit of taking felodipine must be carefully weighed against its risks.
It is not known if felodipine passes into breast milk. Nursing mothers who take felodipine should use infant formula.
Seniors: Seniors, especially those with liver disease, are more sensitive to the effects of this drug.

Estazolam - Estrogens - Eszopiclone - Exemestane - Exenatide
August 13, 2009 | Leave a Comment
Generic Name
Estazolam (es-TAZ-oe-lam) V
Type of Drug Benzodiazepine sedative.
Prescribed For
Insomnia and sleep disturbances.
General Information
Estazolam is a member of the group of drugs known as benzodiazepines. They work by a direct effect on the brain. Benzodiazepines make it easier to go to sleep and decrease the number of times you wake up during the night. Estazolam is considered an intermediate-acting sedative and generally remains in your body long enough to give you a good night’s sleep with minimal “hangover.”
Cautions and Warnings
Do not take estazolam if you are allergic or sensitive to any of its ingredients. Severe allergic reactions may occur. People with respiratory disease taking estazolam may experience sleep apnea (intermittent cessation of breathing during sleep). People who already have, or suspect they have, sleep apnea should not take estazolam.
People with kidney or liver disease should be carefully monitored while taking estazolam. Take the lowest possible dose to help you sleep.
Clinical depression may be increased by estazolam, which can depress the nervous system. Intentional overdose is more common among depressed people who take sleeping pills than among those who do not.
All benzodiazepines can be addictive if taken for long periods of time and can cause drug withdrawal symptoms if discontinued suddenly. It should be used With caution in people with a history 0 YATUg dependence. Withdrawal symptoms include tremors, Muscle cramps, insomnia, agitation, diarrhea, vomiting, sweating, and convulsions.
People with a history of seizures should not abruptly stop taking estazolam.
Possible Side Effects
♦ Common: drowsiness, headache, dizziness, talkativeness,
nervousness, apprehension, poor muscle coordination, light-
headedness, daytime tiredness, muscle weakness, slow-
ness of movement, hangover, and euphoria (feeling “high”).
♦ Less common: nausea, vomiting, rapid heartbeat, confusion, temporary memory loss, upset stomach, stomach cramps and pain, depression, blurred or double vision and other visual disturbances, constipation, changes in sense of taste, appetite changes, stuffy nose, nosebleeds, common cold symptoms, asthma, sore throat, cough, breathing difficulties, diarrhea, dry mouth, allergic reaction, fainting, abnormal heart rhythm, itching, acne, dry skin, sensitivity to bright light or to the sun, rash, nightmares or strange dreams, sleeplessness, tingling in the hands or feet, ringing or buzzing in the ears, ear or eye pain, menstrual cramps, frequent urination and other urinary difficulties, blood in the urine, discharge from the penis or vagina, lower back and joint pain, muscle spasms and pain, fever, swollen breasts, and weight changes.
✓ Rare: Rare side effects can affect your heart, stomach and intestines, urinary tract, blood, muscles, and joints. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• As with all benzodiazepines, the effects of estazolam are enhanced if it is taken with an alcoholic beverage, antihistamine, sedative, barbiturate, anticonvulsant medication, antidepressant, or monoamine oxidase inhibitor antidepressant.
• Carbamazepine and phenytoin may reduce blood levels and the effectiveness of estazolam by stimulating liver enzymes responsible for its breakdown.
• Ketoconazole, itraca(\ailzAe, netazodone, fluvoxamine, diltiamm,’isoniazid, some macrolide antibiotics, contraceptive drugs, cimetidine, and disulfiram may increase the effect of estazolam by interfering with the drug’s breakdown in the liver. Probenecid also increases estazolam’s effects by interfering with it passing through the kidneys into urine.
• Cigarette smoking, rifampin, and theophylline may reduce the effect of estazolam.
• Levodopa + carbidopa’s effectiveness may be decreased by estazolam.
• Estazolam may increase the amount of zidovudine (an HIV drug—also known as AZT), phenytoin, or digoxin in your bloodstream, increasing the chances of side effects.
• The combination of clozapine and benzodiazepines has led to respiratory collapse in a few people. Estazolam should be stopped at least 1 week before starting clozapine treatment.
Food Interactions
Estazolam may be taken with food if it upsets your stomach.
Usual Dose
Adult (age 18 and over): 1-2 mg at bedtime.
Senior: 1 mg at bedtime. Small or frail patients should start on 0.5 mg. Dosage should be increased cautiously.
Child (under age 18): not recommended.
Overdosage
The most common overdose symptoms are confusion, sleepiness, depression, loss of muscle coordination, and slurred speech. Coma and death may also occur. People who take an estazolam overdose must be made to vomit with ipecac syrup—available at any pharmacy—to remove any remaining drug from the stomach: Call your doctor or a poison control center before doing this. The victim must be taken to a hospital emergency room for treatment if 30 minutes have passed since the overdose was taken or if symptoms have begun to develop. ALWAYS bring the prescription bottle or container.
Special Information
Never take more estazolam than your doctor has prescribed. Avoid alcoholic beverages and other nervous system depressants while taking estazolam.
Exercise caution while performing tasks that require concentration and such as driving: estazolam may make you tired, dizzy, or lightheaded. People taking estazolam or any other sleeping medicine may experience unusual and complex reactions while asleep, such as driving, making phone calls, and cooking with no memory of the event.
If you take estazolam daily for 3 or more weeks, you may experience some withdrawal symptoms when you stop taking the
drug, especially temporary sleep disturbance. In rare cases, patients discontinuing estazolam have suffered seizures or delirium. Patients with a history of seizures should taper when stopping use
of this drug.
If you forget to take a dose of estazolam and remember within about 1 hour of your regular time, take it right away. If you do not remember until later, skip the dose you forgot and go back to your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Estazolam absolutely should not be used by pregnant women or by women who may become pregnant.
Estazolam passes into breast milk. The drug should not be taken by nursing mothers.
Seniors: Seniors are more susceptible to the effects of estazolam. Type of Drug

Prescribed For
Moderate to severe menopausal symptoms such as hot flashes, night sweats and sleep problems, vaginal dryness and irritation (creams and gels); also prescribed for ovarian failure, osteoporosis prevention, male breast cancer, advanced prostate cancer, abnormal bleeding of the uterus, female castration, Turner’s syndrome, and birth control.
General Information
Six estrogens have been identified in women but only 3 are present in large amounts: estradiol, estrone, and estriol. Estradiol is the most potent and most important. Other estrogens are produced by chemical conversions in the body. Estradiol, for example, is transformed into estrone, which in turn becomes estriol. Estrogens all have the same actions and side effects; only potency varies. More potent types require smaller dosages to produce the same effect.
Millions of women have taken hormone replacement therapy (HRT) to manage menopausal symp<oms, but studies show that HRT doeq WMpYove quality of life for most. Women who experience severe menopause symptoms must weigh the benefits of prolonged hormone replacement therapy against its risks.
Estrogens are largely responsible for the growth and maintenance of the female reproductive system and sex characteristics. They affect the release of hormones from the pituitary gland (con-troller of hormone production and regulator of basic bodily functions). These hormones control the functioning of capillaries (smallest blood vessels), may cause fluid retention, affect protein breakdown in the body, prevent ovulation and breast engorgement after childbirth, and influence the shaping and maintenance of the skeleton through an effect on calcium.
Estrogen products differ in their hormone content and dosage. Some may affect one part of the body more than another. Generally, though, estrogens are interchangeable as long as dosage differences are taken into account.
Cautions and Warnings
Do not take estrogens if you are allergic or sensitive to any of their ingredients.
Products containing an estrogen and a progestin should not be used for the prevention or treatment of bladder-control problems, heart disease, or mental decline (dementia).
Women with an intact uterus who choose hormone replacement therapy for menopausal symptoms should take the lowest effective dose for the shortest possible time to minimize the risks associated with these medicines. The results of a very large study called the Women’s Health Initiative (WHI) first published in 2002 and updated with new reports, have drastically changed the face of estrogen replacement therapy. The study found a small but insignificant increase in the risk of non-fatal heart attacks. There was no increase in heart disease in the estrogen plus progestin part of the WHI. Early results of the WHI found 4-6 more cases of invasive breast cancer for every 10,000 women in the study and tumors were harder to detect. But this result was not confirmed after more than 7 years of additional study. Estrogens may also lead to abnormal mammograms. An increased risk of a stroke was found in the WHI study. The risk of blood clots forming in the body was doubled in women taking hormone therapy. This study did show some benefits of long-term hormone replacement in colon cancer and osteoporosis, but these benefits may not outweigh the risks of hormone replacement therapy.
Women with liver damage or disease, blood-clotting problems, or abnormal vaginal bleeding whose cause is unknown, should not take estrogens.
Women who smoke cigarettes and take estrogen have a greater risk of cardiovascular side effects, including stroke and blood clotting.
Estrogens may increase the risk of endometriat cancer by 4.514 times in postmenopausal women taking them without progestin for prolonged periods of time; the risk depends on duration of treatment and dosage. Women who have a strong family history of breast cancer or who have breast nodules or cysts or an abnormal mammogram should be cautious about using estrogens. Women with estrogen-dependent cancer or breast cancer should not take estrogens, except some being treated for breast cancer that has spread. Women taking an estrogen for breast cancer that has spread to their bones can develop large increases in blood calcium.
Postmenopausal women taking estrogen are 2-3 times more likely to develop gallbladder disease.
Estrogens can raise blood pressure. Pressure usually returns to normal when the drug is stopped.
People with thrombophlebitis should avoid these drugs. The risk is greatest with very high dosages. Lower hormone dosages may not be a problem.
Estrogens should not be used to treat painful breast enlargement that sometimes develops after giving birth.
Estrogens can cause significant increases in blood triglycerides and cause pancreas inflammation in women with inherited blood-fat disorders.
Vaginal estrogen cream may stimulate bleeding of the uterus. It may also cause breast tenderness, vaginal discharge, and withdrawal bleeding if the product is suddenly stopped. Women with endometriosis may experience heavy vaginal bleeding.
Women taking hormone replacement therapy are at a 50% greater than normal risk of senile dementia.
Drospirenone, a progestin and an ingredient in Angeliq, can raise blood potassium levels in some people because it opposes the hormone aldosterone. It should not be used in people with conditions that can lead to high blood potassium such as kidney disease or a poorly functioning adrenal gland. Drospennone should be used with caution by women who we also taking other medicines that raise tl(QW potassium, such as nonsteroidal antiWkvmmMory drugs (NSAIDs), potassium-sparing diuretics, potassium supplements, angiotensin-converting enzyme (ACE) inhibitors, All receptor antagonists, and heparin. Your doctor may want to check your blood potassium level if you might be at risk of high blood potassium.
Possible Side Effects
v Most common: breast enlargement or tenderness, ankle and leg swelling, appetite loss, weight changes, water retention and bloating, nausea, vomiting, and abdominal cramps. The estrogen patch may cause rash, irritation, and redness where it is applied.
V Less common: bleeding gums, breakthrough vaginal bleeding, vaginal spotting or discharge, changes in menstrual flow, painful menstruation, premenstrual syndrome (PMS), absence of menstrual periods during and after estrogen use, uterine fibroid enlargement, vaginal Candida infection, a cystitis-like condition, mild diarrhea, yellowing of the skin or whites of the eyes, eye lesions, contact-lens intolerance, rash, hair loss, development of new hairy patches, migraine, mild dizziness, depression, increased sex drive (women), and decreased sex drive (men).
♦ Rare: stroke, blood-clot formation, dribbling or sudden passage of urine, loss of coordination, chest pain, leg pain, breathing difficulties, slurred speech, and changes in vision. Men who take large estrogen dosages for prostate cancer have a greater risk of heart attack, phlebitis, and blood clots in the lungs. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Phenytoin, ethotoin, mephenytoin, and topiramate may interfere with estrogen’s effects.
• Estrogens may reduce the effect of oral anticoagulant (blood-thinning) drugs. Your anticoagulant dosage may need an adjustment.
• Estrogens may increase the side effects of antidepressants and phenothiazine sedatives.
• Low estrogen dosages may increase 0\enolhiazine’s effectiveness.
% ‘ittrogens may increase cyclosporine and corticosteroid blood levels. Dosage adjustments of the non-estrogen drugs may be needed.
• Estrogens may reduce the effectiveness of thyroid replacement therapy.
• Rifampin, barbiturates, carbamazepine, St. John’s wort, and other drugs that stimulate the liver to break down drugs may reduce estrogen blood levels.
• Estrogens may interfere with tamoxifen and bromocripline.
• Women, especially those ova. 35, who smoke cigarettes and take estrogen have a much greater risk of developing stroke, hardening of the arteries, or blood clots in the lungs. The risk increases with age and tobacco use.
• Estrogens interfere with many diagnostic tests. Make sure your doctor knows you are taking estrogen before conducting any blood tests or other diagnostic procedures.
Food Interactions

Special Information
Call your doctor if you develop breast pain or tenderness, swelling of the feet and lower legs, rapid weight gain, chest pain, breathing difficulties, pain in the groin or calves, unusual or persistent vaginal bleeding, missed menstrual period, lumps in the breast, sudden severe headache, dizziness or fainting, disturbances in speech or vision, weakness or numbness in the arms or legs, abdominal pain, sudden severe vomiting, depression, yellowing of the skin or whites of the eyes, or jerky or involuntary muscle movement.
Women taking estrogens or combined estrogen and progestin therapy should have yearly lamasN exams, perform monthly breast self -Paw i)26ions, and have regular mammograms.
Talk to your health care provider about ways to reduce risk factors for heart disease (blood-pressure control, improving your diet, stopping tobacco use) and osteoporosis (an appropriate diet, vitamin D and calcium supplements, weight-bearing exercise).
Tell your doctor if you are having surgery or require bedrest: your doctor may have you stop taking estrogen 4-6 weeks beforehand to prevent the risk of blood clots.
Your doctor should reevaluate your need for estrogen vaginal cream every 36 months. Do not stop using the drug suddenly because this may increase your risk of developing unpredicted or breakthrough vaginal bleeding.
Women using the cream who develop breast tenderness, start to bleed, or have other vaginal discharge should contact their doctors at once.
Estrogen skin patches should be applied to a clean, dry, non-oily, hairless area of intact skin, preferably on the abdomen. Do not apply it to your breasts or waist, or to any area where tightfitting clothes may loosen the patch from your skin. The application site should be rotated to prevent irritation, and each site should have a patch-free period for 7 days.
Good dental hygiene is important while taking estrogen because estrogen may increase your risk of oral infection. Dental work should be completed prior to starting estrogen, if possible.
Vaginal estrogen cream should be inserted high into the vagina, about 2/3 of the length of the applicator.
Press the vaginal ring into an oval and insert as deeply as possible in the upper 1/3 of the vagina.
Some of these products contain tartrazine (a commonly used orange dye and food coloring). If you are allergic to tartrazine or have asthma, check with your pharmacist to find out if your estrogen product contains this coloring agent.
If you forget a dose, take it as soon as you remember. If it is almost time for your next dose, skip the one you forgot and continue with your regular schedule. Do not take a double dose.
Authorities note that the risk of serious complications for an individual woman taking hormone replacement therapy is very small. Thus, you may decide to take hormones but your decision should be based on a complete discussion of the facts and your individual situation with your doctor. Continue to talk with your doctor regularly about weighing tt% i1%’Ks against the benefits of taking estrQ(;e5\.
Special Populations
Pregnancy/Breast-feeding: Estrogens harm the fetus and should never be used during pregnancy for any reason.
Estrogens pass into breast milk and reduce its flow. Nursing mothers who must take them should use infant formula.
Seniors: The risk of side effects increases with age, especially if you smoke. Women age 65 or older taking estrogens may be more likely to develop a stroke, blood clot, or dementia, a condition where people suddenly or gradually lose normal mental function and intellectual capacity.
Generic Name
Eszopiclone (ess-oh-PIK-lone)
Brand Name Lunesta
Type of Drug Sedative.
Prescribed For Insomnia.
General Information
Eszopiclone is a nonbenzodiazepine sleeping pill that is believed to work in much the same way as the drug zolpidem and as benzodiazepine-type sleeping pills and sedatives. Unlike the benzodiazepines, however, eszopiclone has little muscle-relaxing or antiseizure effects. This drug is rapidly absorbed and usually starts working within a few minutes. Eszopiclone causes little or no “hangover,” and there are no rebound effects after stopping the drug. In studies of eszopiclone, tolerance to its effects did not develop even after 6 months of continued use. Eszopiclone is broken down in the liver, and the level of this drug in the body does not increase after you take it for several days.
Cautions and Warnings
Do not take eszopiclone if you are allergic or sensitive to any of its ingredients.
People With severe liver disease should use eszopiclone with caution and must take less of this medication than those with normal liver function or mild liver disease.
Sleeping problems often result from a physical or psychological illness. Eszopiclone does not affect the underlying causes of
insomnia. It should be taken only with your doctor’s knowledge. If you cannot sleep even after 7-10 days of taking eszopiclone, con-
tact your doctor.
Eszopiclone has caused amnesia (memory loss), but this happens mostly at dosages larger than 2 mg per night.
Suddenly stopping eszopiclone after having taken it for some time may produce drug withdrawal (symptoms include fatigue, nausea, flushing, lightheadedness, crying, vomiting, stomach cramps, panic, nervousness, and general discomfort).
People with a history of substance abuse may be more likely to develop drug dependence on eszopiclone. Eszopiclone doses of 612 mg are similar to 20 mg of diazepam in their potential for abuse.
Eszopiclone is a nervous system depressant and may cause loss of coordination and concentration. It should be taken just before bedtime. People taking sleep medicine may experience unusual and complex reactions while asleep, such as driving, making phone calls, or cooking with no memory of the event. Eszopiclone may also interfere with normal activities the next day, especially if taken with alcohol.
Eszopiclone should be avoided by people with severe depression, severe lung disease, and sleep apnea (intermittently stopping breathing when you are asleep). You should not take this drug if you are drunk.
Possible Side Effects
Adults
Some side effects are more likely with larger doses (viral infection, dry mouth, dizziness, hallucinations, infections, rash, and unpleasant taste).
♦ Most common: headache, drowsiness, unpleasant taste, and lung infections.
✓ Common: dry mouth, dizziness, and nausea.
✓ Less common: nervousness, vomiting, viral infections, anxiety, confusion, depression, hallucinations, reduced sex drive, rash, male breast e”k-aigement and/or pain, painful meR%k5UMlrjn, chest pain, migraines, and swelling of the arms or legs.
♦ Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Mixing eszopiclone with olanzapine can affect your coordination and ability to perform tasks.
• Mixing eszopiclone with ketoconazole more than doubles blood levels of eszopiclone. Other drugs that may have a similar interaction include itraconazole, clarithromycin, nefazodone, troleandomycin, ritonavir, and nelfinavir.
• Rifampin can be expected to drastically reduce the effectiveness of eszopiclone because it increases levels of liver enzymes that break down eszopiclone.
• Avoid combining eszopiclone with alcohol and other nervous system depressants, including sedatives, narcotics, barbiturates, antidepressants, and antihistamines.
Food Interactions
For the most rapid and complete effect, take eszopiclone on an empty stomach at least 2 hours after a meal. It will take longer for eszopiclone to work if you have had a high-fat meal immediately before taking it.
Usual Dose
, abnormal dreaming, nery
Adult (q% 1% and over): 2-3 mg immediately before bedtime or after you are in bed and have trouble falling asleep. Eszopiclone can act very quickly.

Overdosage
Overdose can result in nervous system depression, from unconsciousness to light coma. Combining eszopiclone with alcohol or other nervous system depressants may be fatal or affect other body organs. One person took up to 36 mg of eszopiclone and fully recovered. Take the victim to a hospital emergency room at once. ALWAYS bring the prescription bottle or container.
Special Information
Eszopiclone may cause tiredness, drowsiness, and an inability to concentrate. Be careful when driving or performing any task that requires concentration on the day following a dose. Make sure you get 7-8 hours of sleep after taking eszopiclone.
People taking eszopiclone on a regular basis may develop a drug withdrawal reaction if the medication is stopped suddenly (see “Cautions and Warnings”).
Do not take a double dose of this medication.
Special Populations
Pregnancy/Breast-feeding: Some animal studies with doses of eszopiclone up to 800 times the human equivalent showed it did not affect a developing fetus, and other studies showed some modest effects. However, there is no information on the use of eszopiclone in pregnant women. If your doctor considers eszopiclone crucial for you, its potential benefits must be carefully weighed against its risks.
It is not known if eszopiclone passes into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors, who are likely to be more sensitive to eszopiclone and its side effects, should start on a 1 -mg dose and take the lowest effective dosage.

Generic Name
Exemestane (ex-eh-MES-tane)
Bnj(kod WaYne Aromasin
Type of Drug Aromatase inhibitor.
Prescribed For
Breast cancer. Also prescribed for prostate cancer prevention.
General Information Some breast cancers depend on the presence of the hormone estrogen to stimulate their growth. Depriving these cancers of estrogen is an effective way of treating the condition. Exemestane significantly reduces the amount of estrogen in the blood by binding permanently to an enzyme called aromatase, an essential element in the conversion of androgen (male hormones) to estrogen in premenopausal and postmenopausal women. Exemestane does not affect other hormones in the body. Exemestane is broken down in the liver.
Cautions and Warnings
Do not take exemestane if you are allergic or sensitive to any of its ingredients.
Exemestane may be prescribed for men and postmenopausal women only.
Possible Side Effects
✓ Most common: fatigue, hot flashes, pain, depression, sleeplessness, anxiety, nausea, and breathing difficulties.
✓ Common: flu-like symptoms, leg swelling, high blood pressure, dizziness, headache, vomiting, abdominal pain, leg swelling or other fluid retention, sweating, appetite loss, constipation, and coughing.
✓ Less common: increased appetite, diarrhea, fever, weakness, tingling in the hands or feet, broken bones, bronchitis, sinusitis, rash, itching, urinary infection, and swollen lymph glands.
♦ Rare: chest pain; confusion; reduced sensitivity to stimulation; upset stomach; joint, back, or other bone pain; respiratory infection; sore throat; runny nose; and hair loss. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Estrogen-containing drugs reduce the effectiveness of exemestane. Do not combine these drugs.
• Rifampin, phenytoin, carbamazepine, phenobarbital, and St. John’s wort may potentially reduce the effectiveness of
exemestane.
Food Interactions
Take this drug with a meal. The amount of exemestane absorbed into the blood is increased by 40% when taken with a high-fat meal.
Usual Dose
Adult: 25 mg once a day with or just after a meal. Dose adjustment is not needed in people with kidney or liver disease. Child: not recommended.
Overdosage
Doses as large as 600 mg have been well tolerated by women with advanced breast cancer. Overdose victims should be taken to a hospital emergency room for evaluation and treatment. ALWAYS bring the prescription bottle or container.
Special Information
If you forget a dose, skip the forgotten dose and continue with your regular schedule. Contact your doctor if you skip more than one dose.
Special Populations
Pregnancy/Breast-feeding: Exemestane is intended only for postmenopausal women. It can cause birth defects and miscarriage and should not be used by pregnant women or women who may become pregnant.
Exemestane may pass into breast milk. Nursing mothers who must take it should use infant formula.
Seniors: Seniors may take this drug without special precaution.
Generic Name
Exenatide (ex-EN-ah-tide)
Brand Name Byetta
7Vpe of Drug Incretin mimetic.
Prescribed For Type 2 diabetes.
General Information
Exenatide is a unique drug that improves blood sugar control in people with type 2 diabetes who have been unsuccessful with diabetes pills. It is added to existing therapy and does not replace other treatments. Exenatide has many of the same actions as GLP-1, a natural incretin hormone. It differs chemically and works differently from other diabetes medications, including insulin.
Exenatide begins working about 30 minutes after injection and continues to work for at least 8 hours. It helps the pancreas to release insulin into the blood in response to sugar levels, so insulin rises when blood sugar is high and declines as blood sugar declines. It reduces the production of a hormone called glucagon, which raises blood sugar. Exenatide also keeps food in the stomach longer, which in turn helps reduce the amount of sugar absorbed from dietary sources. Exenatide increases the number of beta cells (that produce insulin) in animals and may have the same effect in humans. This could help reduce the need for other medicines and improve diabetes control.
Cautions and Warnings
Do not take exenatide if you are allergic or sensitive to any of its ingredients.
This drug is not a substitute for insulin. Exenatide has only been studied together with metformin, glitazones, and/or sulfonylureas. It has not been studied with other diabetes pills or insulin.
People with severe kidney disease should not use exenatide.
People with severe stomach or intestinal disease should not use exenatide.
Inflammation of the pancreas can occur with this drug. Symptoms include nausea, vomiting, fever, rapid pulse, and painful and swollen abdomen that may develop slowly and worsen when you eat or may be severe and constant.
Low blood sugar may ziccurit you are taking exenatide with a S\00ny)urea-type antidiabetes drug or with a glitazone.
Antibodies to exenatide may develop, but antibody levels generally go down with time. Most patients who develop antibodies still have good sugar control and similar types of side effects as people who do not develop exenatide antibodies.
Possible Side Effects
♦ Most common: nausea, vomiting, diarrhea, and low blood sugar (when mixed with a sulfonylurea-type drug or metformin plus a sulfonylurea).
♦ Less common: low blood sugar (when mixed with a glitazone), feeling jittery, dizziness, headache, and upset stomach.
✓ Rare: rash, abdominal swelling and pain, constipation, and kidney failure. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Exenatide has been studied with a number of other medications commonly taken by people with diabetes (digoxin, lovastatin, lisinopril, and acetaminophen) and no significant interactions were noted.
• Combining exenatide with a sulfonylurea-type drug may lead to hypoglycemia (low blood sugar). Your doctor may change your sulfonylurea dose to solve this problem.
• Take all oral medicines at least 1 hour before you inject exenatide to ensure maximum absorption. If you must take oral drugs with food or meals, take them with a snack or meal when exenatide is not being injected. Exenatide extends the time that drugs remain in the stomach and may reduce the amount of medication absorbed when taken by mouth.
• Exenatide may reduce the effectiveness of oral contraceptive pills. Take them at least 1 hour before an injection of exenatide.
• Exenatide may increase the amount of warfarin in the body and increase the risk of bleeding.
Food Interactions
None known. Usual Dose
Adult: 5 or 10 mcg twice a day by subcutaneous injection %M)iT) an hour before breakfast and dk”"tj.
CAWVEOnafide has not been studied in children. Overdosage
The effects of an exenatide overdose are severe nausea, severe vomiting, and severe, rapid drops in blood sugar levels. An oral sugar source may help, but overdose victims should be taken to a hospital emergency room for evaluation and treatment. ALWAYS bring the exenatide pen with you.
Special Information
Each dose of exenatide must be given as an injection under the skin of the thigh, abdomen, or upper arm within 1 hour before your breakfast and dinner meals. For information on how to properly administer this drug, see page 1242.
If you forget a dose of exenatide, skip the dose you forgot and continue with your regular schedule. Do not take a double dose.
Exenatide injection is clear and colorless. Do not use if it has any color, is cloudy, or if there are any particles floating in it.
Keep this drug in the refrigerator, and do not use it after the expiration date has passed.
This drug may lead to a loss of appetite and loss of body weight. Do not change your regular dosage if this happens to you.
Special Populations
PregnancylBreast-feeding. In animal studies using doses equal to 3 times the usual human dose, exenatide was shown to affect the growth of the fetus. If you are or might be pregnant and your doctor considers this drug crucial, its potential benefits must be weighed against its risks.
Small amounts of exenatide may pass into breast milk and may affect a nursing infant. Nursing mothers taking this drug should use infant formula.
Seniors: Seniors may take this drug without special restriction. Generic Name

Entecavir (m-M-ah-veer)
Brand Name Baraclude
Information in this monograph also applies to:
Generic Ingredient: Telbivudine Tyzeka
Type of Drug Antiviral.
Prescribed For
Chronic hepatitis B infection in adults.
General Information
Entecavir is a prescription medicine for adults with chronic hepatitis B virus (HBV) infection in which the virus is multiplying and damaging the liver. Entecavir can reduce the amount of virus in the body, make it harder for new liver cells to be infected by the virus, and improve the general condition of the liver. They work by attacking HBV polymerase, an enzyme essential to the reproduction of the hepatitis B virus inside an infected cell. These drugs are eliminated from the bodj,4kalbe kidney. Telbivudine does not wGCK alg4msl HIV infection and can be taken together with HIV drug therapy. These medicines do not cure HBV or stop you from spreading HBV to others, generally through sexual contact or exposure to infected blood. The HBV virus can live outside the body for one week.
Cautions and Warnings
Do not take these medicines if you are allergic or sensitive to any
of their ingredients.
Entecavir should be used with caution in people who have both HIV and HBV because of possible HIV resistance developing after entecavir is taken.
Severe worsening of HBV has occurred in people who stopped taking this medication.
These drugs can lead to further liver damage. In rare cases, they have been associated with liver failure that resulted in death. The safety of this drug in people who have had a liver transplant is not known.
These drugs are eliminated through the kidneys. People with kidney disease may require lower doses.
Telbivudine has also been associated with lactic acidosis, a condition in which excess lactic acid in the body causes the blood to become acidic. Feeling very weak or tired, experiencing unusual Muscle pain, difficulty breathing, stomach pain with nausea and vomiting, feeling cold—especially in your arms and legs, feeling dizzy or lightheaded, and a fast or irregular heartbeat may be signs of lactic acidosis. It is a medical emergency and must be treated in the hospital. This has happened in some people taking these medications.

There are no reports of entecavir overdose. People taking single doses up to 40 mg or multiple doses up to 20 mg per day for up to 14 days had no unusual side effects. One person accidentally took an overdose with no consequences. People taking up to 1800 mg a day of telbivudine had no increase in side effects. Overdose victims should be taken to a hospital emergency room for treatment, where dialysis may be necessary to remove the drug from the blood. ALWAYS bring the prescription bottle or container.
Special Information
Call your doctor il you develop muscle aches, pains, or weakness; ‘it your skin or the white part of your eyes turns yellow; if your urine becomes dark; if your bowel movements turn light in color; if you don’t feeling like eating food for several days or longer; if you become nauseous; or if you have lower stomach pain. These can be signs of a serious liver problem called hepatotoxicity, which has occurred in some people taking these medications.
Your hepatitis B may get worse or become very serious if you stop taking these medications. Do not stop taking them or change your daily dose without talking to your doctor.
If you forget to take your daily entecavir dose, take it as soon as you remember but do not take a double dose. Call your doctor if you forget to take 2 or more doses in a row.
Entecavir oral solution is a ready-to-use product and should not be mixed with water or any other liquid product. Each bottle of the oral solution comes with a dosing spoon that is calibrated in 1 -mL increments, up to 10 mL. Hold the spoon upright and gradually fill it to the mark next to the prescribed dose. Drink the liquid directly from the dosing spoon. Your pharmacist can help you properly measure your medication dose. Rinse the dosing spoon with water after each daily dose and allow it to air dry.
Special Populations
Pregnancy/Breast-feeding: Animal studies of entecavir revealed slowed development of the skeleton. Animal studies of telbivudine did not reveal any effects on the developing fetus. However, it is not known if either medicine is safe to use during pregnancy or if it helps prevent the hepatitis B virus from passing on to a developing fetus. If your doctor considers entecavir or telbivudine crucial for you, potential benefits must be carefully weighed against their risks. A data bank has been established to collect information from doctors on pregnant women who do take these medicines.
These medicines may pass into breast milk. Nursing mothers who must take these drugs should use infant formula.
Seniors: Dosage reduction may be needed in seniors because of normal declines in kidney function.

Type of Drug
Decongestant and expectorant combination.
Prescribed For
Cold or allergy and for nasal congestion, runny nose and cough associated with other upper respiratory conditions.
General Information
The decongestant ingredient in Entex PSE, pseudoephedrine, dramatically reduces congestion and stuffiness. The decongestant ingredients ephedrine and phenylephrine act similarly. The expectorant, guaifenesin, is used to help loosen thick mucus that may contribute to chest congestion; the effectiveness of guaifenesin and other expectorants has not been established. There are other drugs on the market using this same general formula—an expectorant plus a decongestant—but they use different decongestant ingredients or a combination of decongestants plus guaifenesin. Nothing cures a cold or allergy, but Entex PSE may provide relief from symptoms.
Cautions and Warnings
Do not take Entex PSE if you are allergic or sensitive to any of its ingredients.
Entex PSE may cause anxiety or nervousness or interfere with sleep.
Do not use Entex PSE if you have ventricular tachycardia (quickened heartrate), or hypertension (high blood pressure).
Entex PSE should be used with extreme caution in those with heart disease, other heart rhythm disorders, thyroid disease, diabetes, glaucoma, stomach ulcer, urinary blockage, or a prostate condition.
Entex PSE should not be used over extended periods of time to treat persistent or chronic cough especially one that may be caused by cigarette smoking, asthma, or emphysema.
Possible Side Effects
Mritl common: anxiety, restlessness, sleeplessness, tension, excitation, dizziness, drowsiness, and headache.
♦ Less common: nausea, vomiting, upset stomach, low blood pressure, heart palpitations, chest pain, rapid or slow heartbeat, abnormal heart rhythms, irritability, euphoria (feeling Possible Side Effects (continued)
“high”), eye irritation and tearing, hysterical reaction, appetite loss, kidney stones, urinary difficulties in men with a prostate condition, weakness, loss of facial color, and breathing difficulties.
Drug Interactions
• Entex PSE should be avoided if you are taking a monoamine oxidase inhibitor (MAGI) antidepressant for depression or hypertension because the MAGI may cause a very rapid rise in blood pressure or increase side effects such as dry mouth or nose, blurred vision, and abnormal heart rhythms.
• The decongestant in Entex PSE may interfere with bloodpressure-lowering medication.
Food Interactions
Take Entex PSE with food if it upsets your stomach.
Usual Dose
Adult and Child (age 12 and over): 1 tablet or capsule twice a day or 2 tsp. of liquid 4 times a day.
Child (age 6-11):1/2-1 tablet or 1 capsule twice a day or 1 tsp. of liquid 4 times a day.
Overdosage
Most cases of overdose are not severe. Symptoms include sedation, sleepiness, increased sweating, and increased blood pressure. Hallucinations, convulsions, nervous system depression, and breathing difficulties are more prominent in older adults. Most cases of overdose are not severe. Induce vomiting with ipecac syrup—available at any pharmacy. Call your local poison control center or a hospital emergency room before doing this. If you lseey, treatment. ALWAYS bring the prescription bottle or container.
-SIDt’dial Information
Call your doctor if your side effects are severe or gradually become intolerable.

fant formula.
Seniors: Seniors are more sensitive to the effects of Entex PSE.
Generic Name
Epoetin (EE-poh-eh-tin)
Brand Names Epogen
Type of Drug
Red-blood-cell growth stimulator.
Prescribed For
Anemia; may also be used for reducing the need for blood or redblood-cell transfusions.
General Information
Epoetin is a natural hormone that stimulates the bone marrow to produce red blood cells. It is used for anemia that does not respond to iron supplements. In most cases of anemia, there are plenty of red blood cells circulating, but they lack iron. People who need epoetin do not have enough red blood cells. Epoetin stimulates the production of new red blood cells to carry needed oxygen.
Cautions and Warnings
Do not use epoetin if you are allergic or sensitive to albumin or products manufactured from animal cells.
People with urtvaRtmliked high blood pressure should not use epoetin.
Some people with chronic kidney failure and severe anemia should not take epoetin. Epoetin is not a replacement for emergency blood transfusion.
Epoetin is not intended for anemia caused by folate or iron deficiency, hemolysis, or gastrointestinal bleeding.
Procrit People using epoetin may require anticoagulant medicine to prevent blood clotting during treatment. Tell your doctor it you have any blood-clotting disorders.
In rare cases, people taking epoetin may have seizures. Avoid driving or any other activities where a sudden seizure could be dangerous. Do not take epoetin if you have a history of seizures or strokes.
Epoetin should be avoided in patients with blood cancers such as lymphoma, because it can act as a growth factor for the tumor.
If your hemoglobin levels become too high, your chance of heart attack, stroke, heart failure, blood clots, and death is increased. It is important to have your blood tested and adjust dosage of epoetin accordingly throughout treatment.
Possible Side Effects
Side effects reported in studies of epoetin were similar to those reported with an inactive placebo (sugar pill).
♦ Most common: high blood pressure, headache, constipation, diarrhea, nausea, joint pain, fever, fatigue, itching, rash, and difficulty breathing.
✓ Common: swelling, vomiting, chest pain, skin reactions at the site of injection, weakness, dizziness, urinary infections, diarrhea, upset stomach, blood clots, anxiety, tingling in the hands or feet, and trunk pain.
✓ Rare: stroke and heart attack. Contact your doctor if you experience any side effect not listed above.
Food and Drug Interactions None known.
Usual Dose
Adult: starting dose-23-69 units per 1b. of body weight 3 times a week by intravenous or subcutaneous injection. Final dose is based on response and need. Surgery patients take 138 units per lb. for 10 days before Surgery or 276 units once a week for 3 weeks before surgery and another dose on the day of surgery. Dialysis patients take epoetin once a week.
Child (under age 12): 23 units per lb. of body weight 3 times a week by intravenous or subcutaneous injection. Final dose is based on response and need.
Child (under 1 month): not recommended.
Overdosage
Little is known about the effects of epoetin overdose. Call your local poison control center or a hospital emergency room for information. If you seek treatment, ALWAYS bring the prescription container.
Special Information
People taking epoetin should have regular blood tests to assure the drug is working well. Your doctor may want to take blood samples twice a week for several weeks and then test your blood regularly.
Epoetin has been used by athletes to enhance physical performance. This is called blood doping and has resulted in several deaths because the percentage of red blood cells in a blood sample can reach hazardous levels.
Epoetin must be stored in a refrigerator.
Most patients will need to take iron supplements with this drug.
This drug can be given by injection under the skin. For more in-
formation on how to properly administer this drug, see page 1242.
Special Populations
Pregnancy/Breast-feeding: Animal studies suggest that epoetin may enter fetal circulation. When this drug is considered crucial by your doctor its potential benefits must be carefully weighed against its risks.
It is not known if epoetin passes into breast milk. Nursing mothers who must take it should use infant formula.
Seniors: Seniors may use this product without special precaution.
Type of Drug
Erectile Dysfunction Drugs
Generic Ingredient: Sildenafil Citrate
Viagra Revatio
Generic Ingredient: Tadalafil Cialis
Generic Ingredient: Vardenafil Levitra
Prescribed For
Erectile dysfunction (ED). sildenafil is also prescribed for pulmonary
hypertension.
General Information
The chemical nitric oxide is released in the penis during sexual stimulation. Nitric oxide causes the release of an enzyme called cyclic guanosine monophosphate (cGMP), which increases blood flow into the penis, producing an erection. cGMP is broken down by the enzyme phosphodiesterase type 5 (PDE5). In men with low levels of cGMP, these medicines help achieve and maintain an erection by inhibiting PDE5, thus causing higher levels of cGMP. ED can be the result of nerve, blood vessel, or psychological problems. These drugs, which are effective in about 70% of men, only help when poor blood flow is the cause of the dysfunction. Women have reported some benefit from sildenafil, although it has been widely studied only in men. Vardenafil and tadalafil are intended only for men. These medicines start working in 30-60 minutes and their effects usually last from 2-4 hours, although some have noted an effect for 24 hours or more. Some drug interactions and kidney or liver diseases extend this time. Tadalafil begins working in 30-60 minutes and can remain in the body for more than 2 days, much longer than the other medicines in this group. Low-dose tadalafil may be taken every day for chronic ED.
Pulmonary hypertension, a rare disease in which high pressure in the blood vessels moves from the heart to the lungs, is sometimes treated with sildenafil.
Cautions and Warnings
Do not take ED drugs if you are allergic or sensitive to any of their ingredients.
These medicines lower blood pressure and should be avoided if you have high (greater than 170/100) or low (less than 90/50) blood pressure. Several people have died from a sudden blood-pressure drop after combining erectile dysfunction medications with other medications that can reduce blood pressure.
These Medicines should never be taken by those taking heart medications called nitrates, as fatal reactions have occurred.
People with heart disease may experience heart problems with sildenafil or vardenafil, including a heart attack. These reactions can occur during or shortly after sexual activity.
Avoid these medicines if you have had a heart attack, stroke, or life-threatening abnormal heart rhythms in the past 6 months, or if you have heart failure, unstable angina pectoris, damage to the penis, or a progressive eye disease called retinitis pigmentosa. Blindness is a rare side effect of sildenafil and may be a problem with all of these medications.
People taking sildenafil or vardenafil have experienced difficulties seeing blue or green colors and may see things with a blue tinge surrounding them. This happens because they affect an enzyme in the eye. The effect clears up after the drug passes out of the body.
People with kidney or liver damage retain these medicines in their bodies longer than people whose kidneys and liver function normally. People with kidney or liver problems should always begin with the lowest possible dosage.
People with priapism (painful erection lasting more than 6 hours) or a condition that predisposes them to priapism—such as leukemia, multiple myeloma, or sickle cell anemia—should be cautious about taking these medicines.
Vardenatil and sildenafil should be avoided by people with stomach or bleeding ulcers because its effect on these conditions is not known.
Possible Side Effects
Sildenafil
✓ Most common: headache and flushing.
♦ Less common: upset stomach, stuffy nose, urinary tract infection, diarrhea, rash, dizziness, seizure, anxiety, prolonged and possibly painful erection, double vision, visual changes, bloodshot eyes, burning eyes, swelling in the eye, and blood vessel diseases in the retina.
✓ Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Tadalafil
I Most common: headache.
✓ Common: upset stomach. Back pain and muscle aches can develop 12-24 hours after taking tadalafil and go away on their own after 2 days.
Possible Side Effects (continued)
♦ Less common: flushing, nasal congestion, and arm or leg
pain.
♦ Rare-. prolonged or painful erections. Other rare side ef-
fects can occur in almost any part of the body. Contact
your doctor if you experience any side effect not listed
above.
Vardenafil
✓ Most common: headache and flushing.
✓ Less common: upset stomach, sinus infection, flu-like symptoms, dizziness, and nausea.
♦ Rare: prolonged or painful erection. Other rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Do not combine any of these drugs with nitrates (such as nitroglycerin) and other drugs that lower blood pressure. The combination can cause a sudden, rapid drop in blood pressure.
• Do not take vardenafil if you are taking an alpha blocker (such as alfuzosin, doxazosin, prazosin, tamsulosin, or terazosin). Tadalafil may be taken only with tamsulosin. You may take sildenafil at its lowest possible dose with an alpha blocker, but you must separate the doses by at least 4 hours.
• Combining cimetidine and sildenafil leads to a substantial (more than 50%) increase in the amount of sildenafil in the blood.
• Erythromycin, itraconazole, ketoconazole, and protease inhibitors (used to combat HIV) can cause sildenafil blood levels to almost double. Vardenafil levels can increase by 400-1000% when combined with these medicines. It you are taking one of these medicines, do not take more than the %west possible dose of your ED drug. Do not take tadalafil more than once every 3 days if you are also taking one of these medicines.
• Rifampin can be expected to reduce the effect of ED medicines by reducing the amount of drug in the blood. Other
drugs that may reduce the effects of these drugs are carbamazepine, phenobarbital, and phenytoin.
• Dihydrocodeine—a widely used prescription pain reliever—may increase the effects of sildenafil, yielding substantially prolonged erections, sometimes lasting for hours.
• Do not combine sildenafil, tadalafil, and vardenafil. The effects of combining these drugs are not known.
• Do not take vardenafil if you are taking any medicine to treat an abnormal heartbeat, including amiodarone, procainamide, quinidine, and sotalol.
• Combining sildenafil with selective serotonin reuptake inhibitors (SSRIs) or tacrolimus may increase the risk of sildenafil side effects.
• Alcohol adds to the blood-pressure-lowering effects of these medicines.
Food Interactions
Grapefruit juice may increase the amount of these drugs in the blood. Taking sildenafil with a high-fat meal reduces the amount of drug absorbed. Tadalafil and vardenafil may be taken without regard to food or meals.
Usual Dose
Sildenafil
Adult: 50 mg taken about 1 hour before sexual activity. Individual doses can range from 25-100 mg. The maximum dosing frequency is once a day.
Senior: Begin with 25 mg and gradually increase dosage as needed.
Tadalafil
Adult: 10 mg taken about 1 hour before sexual activity. Individual doses can range from 2.5-20 mg. Do not take more than 1 dose of tadalafil a day.
Senior: Begin with 5 mg and gradually increase dosage as needed.
Adult: 10 mg taken about 1 hour before sexual activity. Individual doses can range from 5-20 mg.
Senior: Begin with 5 mg and gradually increase dosage as needed.
Overdosage
sildenafil and tadalafil overdose are likely to produce exaggerated drug side effects. Vardenafil overdose may cause neck pain, muscle aches, or vision changes. Call your local poison control center or hospital emergency room for more information. If you seek treatment, ALWAYS bring the prescription bottle or container.
Special Information
Call your doctor and do not engage in sexual activity if the erection produced by ED drugs is painful or lasts 4 or more hours, or if you experience dizziness, nausea, or chest pain after taking an ED drug. In rare cases, men taking ED drugs have reported a sudden decrease or loss of vision and/or hearing. Call your doctor right away if you experience this adverse side effect.
People who use organic nitrates for gardening or other purposes can experience a severe and dangerous blood pressure drop if they take sildenafil or vardenafil. It is not known how long you have to wait to resume nitrate use.
These drugs do not protect against sexually transmitted diseases.
Special Populations
Pregnancy/Breast-feeding: There is no evidence that sildenafil or vardenafil harm the fetus; however, they are not intended for pregnant women or nursing mothers.
Seniors: Men age 65 and over eliminate these drugs more slowly than younger men and should begin with the lowest possible dosage.
Generic Name
Ergoloid Mesylates (ER-goe-loid
MES-il-ates) (GI
Brand Names Caerimal
Hydergine
Type of Drug Psychotherapeutic agent.
Hydrogenated Ergot Alkaloids
Prescribed For
Age-related decline in mental capacity.
General Information
Ergoloid mesylates are used to treat decreased mental capacity of unknown cause in people over age 60. These drugs should not be used for any condition that is treatable with another drug or that may be reversible. People who respond to ergoloid mesylates are likely to have Alzheimer’s disease or some other cause of dementia. Nobody knows exactly how ergoloid mesylates produce their effect, but they improve the supply of blood to the brain in test animals, reduce their heart rate, and improve muscle tone in blood vessels. Some studies show the drugs to be very effective in relieving mild symptoms of mental impairment, while others find it to be only moderately effective. They are most beneficial in people whose symptoms are due to the effects of high blood pressure in the brain.
Cautions and Warnings
Do not take ergoloid mesylates if you are allergic or sensitive to any of their ingredients or you have psychotic symptoms or psychosis.
Ergoloid mesylates should be used with caution in people with liver disease, low blood pressure, or slow heartbeat.
Possible Side Effects
Ergoloid mesylates do not produce serious side effects.
♦ Common: When taken under the tongue, these drugs may
cause irritation, nausea, or upset stomach. Other side ef-
fects are drowsiness, slow heartbeat, and rash.
Drug Interactions None known.
Food Interactions
Do not eat, drink, or smoke while you have an ergoloid mesylates pill under your tongue.
Usual Dose
Starting dose is 1-2 mg 3 times a day. Increase as needed. Do not exceed 12 mg a day.
Overdosage
Symptoms include blurred vision, dizziness, fainting, flushing, headache, appetite loss, nausea, vomiting, stomach cramps, and stuffy nose. Take the victim to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
The effects of ergoloid mesylates are gradual and frequently not seen for up to 6 months. A 6-month period of treatment with ergoloid mesylates is recommended before your doctor can fully evaluate your response to the drug. Your doctor should periodically reevaluate your condition to determine if ergoloid mesylates treatment is still needed and that it is working for you.
Dissolve sublingual tablets under the tongue. Do not chew or crush them; they are not effective if swallowed whole.
If you forget a dose, skip it and go back to your regular schedule. Do not take a double dose. Call your doctor if you miss 2 or more consecutive doses.
Special Populations
Pregnancy/Breast-feeding: Ergoloid mesylates may interfere with fetal development. When these drugs are considered crucial by your doctor, their potential benefits must be carefully weighed against their risks.
Ergoloid mesylates pass into breast milk. Nursing mothers who must take these drugs should use infant formula.
Seniors: Seniors are more likely to develop side effects, especially hypothermia (low body temperature).

Generic Ingredients: Erythromycin Ethylsuccinate + Sulfisoxasole
Eryzole Pediazole
Generic Ingredient: Erythromycin Stearate Erythrocin Stearate
Type of Drug Macrolide antibiotic.
Prescribed For
Infections of virtually any part of the body: upper and lower respiratory tract infections; sexually transmitted diseases; urinary tract infections; infections of the mouth, gums, or teeth; and infections of the nose, ears, or sinuses. It is prescribed for acne and may be used for mild to moderate skin infections. Erythromycin is effective against diphtheria and dysentery. It is also prescribed for legionnaires’ disease, rheumatic fever, whooping cough, and bacterial endocarditis. It is prescribed to patients with pelvic inflammatory disease as an alternative to penicillin. The eye ointment is used to prevent newborn gonococcal or chlamydial eye infections.
General Information
Erythromycin and other macrolide antibiotics are either bactericidal (bacteria-killing) or bacteriostatic (inhibiting bacterial growth), depending on the organism in question and amount of antibiotic present. Erythromycin is deactivated by stomach acid, so the tablet form is made to bypass the stomach and dissolve in the intestine.
Since the action of this antibiotic depends on its concentration in the invading bacteria, kk is crucial that you follow your doctor’s ISNVKi10ns regarding the spacing of doses as well as the number of days you must take the medication—otherwise, this antibiotic may be much less effective.
Cautions and Warnings
Do not take erythromycin if you are allergic or sensitive to any of its ingredients or to any macrolide antibiotic.
Erythromycin is excreted primarily through the liver. People with liver disease or damage should consult their doctors. Those on long-term therapy with erythromycin should have periodic blood tests. If you restart erythromycin after having experienced liver damage, it is likely that symptoms will recur within 48 hours.
Erythromycin estolate has occasionally produced liver problems (symptoms include fatigue, nausea, vomiting, abdominal cramps, and fever). If you are susceptible to stomach problems, erythromycin may cause mild to moderate stomach upset; discontinuing the drug will reverse this condition.
Colitis (bowel inflammation) has been associated with all antibiotics and can range from mild to life-threatening (see “Possible Side Effects”),
Possible Side Effects
• Most common: nausea, vomiting, stomach cramps, and diarrhea. Colitis (symptoms include severe abdominal cramps and severe, persistent, and possibly bloody diarrhea) may develop. Side effects of the topical erythromycin include peeling, dryness, itching, and oiliness.
♦ Less common: hairy tongue, itching, irritation of the anal or vaginal region, eye irritation, and skin tenderness. If any of these symptoms appear, call your physician immediately.
♦ Rare: hearing loss—which reverses itself after the drug is stopped and occurs most often in people with liver and kidney problems—and abnormal heart rhythms. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Antacids may slightly affect the release of erythromycin from your body. This effect is not considered important.
• Do not combine erythromycin with astemizole or terfenadine.
• Erythromycin may slow the breakdown of carbamazepine (an anticonvulsant prescribed for seizures). Avoid this combination.
• Mixing erythromycin with rifabutin or rifampin can interfere with the antibiotic’s effect and increase the risk of intestinal side effects.
• Do not combine erythromycin and pimozide. Two people died after combining pimozide and a macrolide antibiotic.
• Erythromycin may neutralize penicillin. It may also neutralize the antibiotics lincomycin and clindamycin.
• Erythromycin interferes with the elimination of theophylline
from the body, possibly leading to theophylline overdose.
• Mixing erythromycin with a statin cholesterol-lowering drug increases the risk of developing a potentially fatal condition involving severe muscle pain and destruction.
• Do not mix erythromycin with sparfloxacin, ketoconazole, itraconazole, fluconazole, diltiazem, verapamil, troleandomycin, mibefradil, nefazodone, or clarithromycin. These mixtures can lead to severe, possibly fatal, abnormal heart rhythms. Grepafloxacin (another fluoroquinolone) should only be mixed with erythromycin in hospitalized patients whose hearts can be monitored during treatment.
• Combining erythromycin and alfentanil (an injectable pain reliever), bromocriptine, buspirone, digoxin, disopyramide, ergotamine, cyclosporine, methylprednisolone (a corticosteroid), tacrolimus, vinblastine, or benzodiazepines (such as alprazolam, diazepam, midazolam, and triazolam) increases the risk of drug side effects.
• Erythromycin estolate may increase the liver side effects of other drugs that affect the liver.
• Erythromycin may increase the anticoagulant (blood-thinning) effects of warfarin in people who take it regularly, especially older adults. People taking this combination should be tested regularly.
• Erythromycin may increase the effects of caffeine.
Food Interactions
Grapefruit juice slows the breakdown of erythromycin, increasing the amount of drug in the blood. For optimum effectiveness, take erythromycin base and erythromycin stearate on an empty stomach with a 6-8 oz. glass of water 1 hour before or 2 hours after meals. Other forms of erythromycin can be taken without regard to food or meals.
\huall Dose
Tablet and Suspension
Adult: 250-400 mg every 6 hours, taken 1 hour before meals, or 500 mg every 12 hours. Maximum dose is 4 g a day.
Child: 15-25 mg per lb. of body weight a day in divided doses depending on age, weight, and severity of infection.
Eye Ointment 1/2 inch 2-6 times a day.
Topical Solution: Apply morning and night.
Doses of erythromycin ethylsuccinate are 60% higher due to differences in chemical composition.
Overdosage
Overdose may cause severe side effects, especially nausea, vomiting, stomach cramps, and diarrhea. Mild hearing loss, ringing or buzzing in the ears, or fainting may also occur. Call your local poison control center or a hospital emergency room for more information. ALWAYS bring the prescription bottle or container.
Special Information
Erythromycin is used instead of penicillin for mild to moderate infections in people who are allergic to penicillin. Erythromycin is not the antibiotic of choice for severe infections.
Erythromycin products should be stored at room temperature, except for oral and topical liquids, which should be kept in the refrigerator.
Call your doctor if you develop nausea; vomiting; diarrhea; stomach cramps; severe abdominal pain; rash, itching, or redness; dark or amber-colored urine; yellowing of the skin or whites of the eyes; or any severe or persistent side effect.
If you forget a dose of oral erythromycin, take it as soon as you remember. If it is almost time for your next dose, space the next 2 doses over 4-6 hours, then continue with your regular schedule. Do not take a double dose.
Remember to complete the full course of therapy prescribed even if you feel well before you finish the medication.
Special Populations
Pregnancy/Breast-feeding: Erythromycin passes into the fetal circulation. Erythromycin estolate has caused mild liver inflammation in about 10% of pregnant women who took it and should not be used if you are or might be pregnant. Other forms of erythromycin have been used sale)y without difficulty.
Erythromycin passes into breast milk. Nursing mothers who must take erythromycin should use infant formula.
Seniors: Seniors with liver disease should use caution. Seniors taking high doses of erythromycin may be at an increased risk of hearing loss.

Efalizumab (ef-ah-LIZ-u-mab)
Brand Name Raptiva
Type of Drug
Immune system suppressant.
Prescribed For
Chronic to severe plaque psoriasis.
General Information
Efalizumab is a manmade antibody that works by binding to specific areas of certain white blood cells called leukocytes. This prevents the leukocytes from interacting with other cells and interrupts inflammation that is involved in the development of patches of psoriatic skin. The molecule that efaluzimab interacts with is found on many other key cells found in the immune system, and this is the source of many of the drug’s more serious side effects.
Cautions and Warnings
Do not use this drug if you are allergic or sensitive to any of its ingredients.
People taking efalizumab are at a greater risk of infection because it suppresses the immune system. Contact your doctor if you develop any kind of infection, including a common cold. Serious infections may require hospitalization.
The chances of malignancy may be increased by efalizumab because it suppresses the immune system. People with any type of cancer should not use this drug.
Efalizumab may lead to bleeding because it can cause a drastic reduction in blood-platelet counts. People with a history of low blood-platelet counts should be extremely cautious about using efalizumab.
Psoriasis can get worse or recur during or after efalizumab treatment in a small number of people. Call your doctor immediately if your condition worsens while you are taking efalizumab.
Possible Side Effects
Headache, fever, nausea, and vomiting are common alter taking the very first dose of elaki7umab. A “conditioning” dose of about 0.3 mg per lb. of body weight is often given to minimize these reactions.
V Most common: headache, infections, chills, nausea, and pain.
V Common: muscle aches, flu-like symptoms, itching, and fever.
Possible Side Effects (continued)
✓ Less common: back pain, arthritis, lung inflammation, and
acne.
♦ Rare: psoriasis, arthritis, joint pain, malignancy, low blood-platelet count, and drug allergy or sensitivity. Other rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Efalizumab is an immune system suppressant and should not be combined with other immune suppressant drugs because of the increased risk of infection and malignancy.
• Combining vaccines (live and acellular) with efalizumab may exaggerate the body’s response to the vaccine and increase the risk of developing the disease against which the vaccination is being administered. People taking etalizurnab should not receive vaccines.
Food Interactions None known.
Usual Dose
Adult: 0.3 mg per lb. of body weight to start. Then about 0.5 mg per lb. of body weight once a week on the same day. The maximum dose is 200 mg by subcutaneous injection. Mix your dose immediately before it is to be injected and throw away any unused medicine.

Generic Name
Enalapril (uh-NAL-uh-pril)
Brand Name
Vasotec
Combination Product
Ggner;c Ingredients: Enalapril + Hydrochlorothiazide RE Vaseretic
Type of Drug
Angiotensi n -converting enzyme (ACE) inhibitor.
Prescribed For
Hypertension (high blood pressure), heart failure, diabetic kidney disease, and heart attack treatment when the function of the left ventricle has been affected. Also prescribed for kidney failure, kidney hypertension, managing people with a high risk of heart disease, chronic kidney disease, and preventing a second stroke.
General Information
Enalapril maleate and other ACE inhibitors work by preventing the conversion of a hormone called angiotensin I to another hormone called angiotensin II, a potent blood-vessel constrictor. Preventing this conversion relaxes blood vessels, thus reducing blood pressure and relieving symptoms of heart failure. Enalapril also affects the production of other hormones and enzymes that participate in the regulation of blood-vessel dilation. Enalapril begins working about 1 hour after you take it and continues to work for 24 hours.
Cautions and Warnings
Do not take enalapril if you are allergic or sensitive to any of its ingredients. Severe sensitivity reactions can occur in hemodialysis patients taking enalapril or those undergoing venom immunization.
Swelling of the face, extremities, or throat has been known to occur with enalapril, which can be dangerous (see “Special Information”).
Enalapril occasionally causes very low blood pressure.
Enalapril may affect your kidney function, especially if you have congestive heart failure. Your doctor should check your urine for protein content during the first few months of treatment. Dosage adjustment of enalapril is necessary if you have reduced kidney function.
Enalapril can affect white-blood-cell counts, possibly increasing your susceptibility to infection. Your doctor should monitor your blood counts periodically.
Enalapril may cause serious Injury or death to the fetus if taken duriRcA pregnancy. Pregnant women should not take enalapril.
ACE inhibitors may be less effective in some black patients with high blood pressure, especially when dietary salt intake is high. Nevertheless, they should still be considered useful blood pressure treatments. Swelling beneath the skin to form welts is more common among black patients.
Possible Side Effects
♦ Most common-. dizziness, fatigue, headache, and chronic cough. The cough usually goes away a few days after you stop taking the medication.
♦ Less common: chest tightness or pain, dizziness when rising from a sitting or lying position, fainting, abdominal pain, nausea, vomiting, diarrhea, bronchitis, urinary tract infection, breathing difficulties, weakness, and rash.
♦ Rare: Rare side effects can occur in almost any part of the body. Contact your doctor if you experience any side effect not listed above.
For additional information about enalapril + felodipine, see Felodipine, page 471.
Drug Interactions
• The blood-pressure-lowering effect of enalapril is additive with diuretic drugs and beta blockers. Any other drug that causes a rapid drop in blood pressure should be used with caution if you are taking enalapril.
• Enalapril may increase the effects of lithium; this combination should be used with caution.
• Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) reduce the blood-pressure-lowering effects of enalapril and other ACE inhibitors. The combination may cause reductions in kidney function.
• Enalapril may increase blood-potassium levels, especially when taken with dyazide or other potassium-sparing diuretics.
• Antacids and enalapril should be taken at least 2 hours apart.
• Capsaicin may trigger or aggravate the cough associated with enalapril therapy.
• Indomethacin may reduce the blood-pressure-lowering effects of enalapril.
• Phenothiazine sedatives and antiemetics may increase the ef - feZIS of enalapril.
• Rifampin may reduce the effects of enalapril.
• The combination of allopurinol and enalapril increases the chance of side effects. Avoid this combination.
• Enalapril affects blood levels of digoxin. More digoxin in the blood increases the chance of digoxin-related side effects, while less digoxin in the blood can compromise its effectiveness.
• Severe sensitivity reactions can occur in those taking allo-
purinol.
For additional information about enalapril + felodipine, see Felodipine, page 471.
Food Interactions
You may take enalapril with food if it upsets your stomach.
Usual Dose
Enalapril
Adult: 5-40 mg a day in 1 or 2 doses. People with poor kidney function need less medication.
Enalapril + Felodipine
Adult: 1-2 tablets a day.
Overdosage
The principal effect of enalapril overdose is a rapid drop in blood pressure, as evidenced by dizziness or fainting. Take the overdose victim to a hospital emergency room immediately. ALWAYS bring the prescription bottle or container.
Special Information
Enalapril can cause swelling of the face, lips, hands, or feet. This swelling can also affect the larynx (throat) or tongue and interfere with breathing. If this happens, go to a hospital emergency room at once. Call your doctor if you develop a sore throat, mouth sores, abnormal heartbeat, chest pain, persistent rash, or loss of taste perception.
Some people who start taking enalapril after they are already on a diuretic (an agent that increases urination) experience a rapid drop in blood pressure after their first doses or when their dosage is increased. To prevent this from happening, your doctor may tell you to stop taking your diuretic 2 or 3 days before starting enalapril or to increase your salt intake during that time. The diuretic may then be restarted gradually.
You may gO dizzy if you rise to your feet too quickly from a sitting or lying position when taking enalapril.
Avoid strenuous exercise or very hot weather because heavy
sweating or dehydration can cause a rapid drop in blood pressure.
While taking enalapril, avoid over-the-counter diet pills, decon-
gestants, and other stimulants that can raise blood pressure. Also,
do not take potassium supplements or salt substitutes containing potassium without consulting your doctor.
If you take enalapril once a day and forget to take a dose, take it as soon as you remember. If it is within 8 hours of your next dose, skip the one you forgot and continue with your regular schedule. If you take enalapril twice a day and miss a dose, take it right away. If it is within 4 hours of your next dose, take 1 dose immediately and another in 5 or 6 hours, then go back to your regular schedule. Never take a double dose.

Generic Name
Entacapone (in-TACK-a-pohn)
Brand Name Comtan
Type of Drug Antiparkinsonian.
Prescribed For
Parkinson’s disease patients for whom levodopa + carbidopa loses its effectiveness between doses.
General Information
Entacapone is always used in combination with levodopa + carbidopa. Some patients experience signs and symptoms of an end-of-dose “wearing-off” effect with these drugs. Entacapone enhances the effect of levodopa + carbidopa by reversing the action of an enzyme known as catechol-O-methyltransferase (COMT), which is primarily responsible for breaking down levodopa in the body.
Cautions and Warnings
Do not take entacapone If yOU are allergic or sensitive to any of At *Ingredients.
Do not take entacapone with phenelzine or tranyleypromine, as a very serious reaction may occur.
People with liver disease should use entacapone with caution as they may accumulate twice as much of this drug in their blood as people with normal liver function.
Entacapone has been rarely associated with the formation of fibrous tissues in unusual places such as the urinary tract and lungs. It has also caused fluid in the lungs.
Entacapone may cause kidney toxicity.
Entacapone may increase the risk of dizziness or fainting when rising from a sitting or lying down position.
Hallucinations have been reported with other Parkinson’s disease drugs.
Possible Side Effects
♦ Most common: difficulty performing voluntary muscle functions, excessive muscle activity, nausea, urine discoloration, and diarrhea.
♦ Common: reduced muscle activity, dizziness, fatigue, constipation, and abdominal pain.
✓ Less common: low blood pressure and fainting when rising from a sitting or lying position, hallucinations, anxiety, agitation, gastritis or other stomach disorders, dry mouth, vomiting, increased sweating, back pain, taste changes, shortness of breath, easy bruising, weakness, and bacterial infection.
♦ Rare: muscle damage or death, high fever, and confusion. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Do not mix entacapone with the monoamine oxidase inhibitor (MAGI) antidepressants phenelzine or tranylcypromine. Entacapone may be taken with the MAGI selegiline.
• Other drugs broken down by COMT will also be affected by entacapone. Isoproterenol, epinephrine, ephedrine, norepinephrine, isoetharine, and others will interact with entacapone, even when taken by inhalation. The result may be increased heart rate, wybylh m ias, and excessive changes in Uwd pressure.
• Cholestyramine, probenecid, erythromycin, rifampin, ampicillin, and chloramphenicol may interfere with the elimination of entacapone from the body.
• Entacapone may enhance the effects of sedatives and other nervous system depressants.
Food Interactions
This drug may be taken with or without food.
Usual Dose
Adult: 200 mg with each levodopa + carbidopa dose, up to
1600 mg a day.
Child: not recommended.
Overdosage
Theoretically, a massive entacapone overdose could prove lethal by completely inhibiting COMT throughout the body. There have been no reports of significant entacapone overdose. Doses up to 800 mg have been taken and side effects were mainly abdominal pain and loose stools. Other effects that might be expected include difficulty breathing, loss of muscle coordination, reduced level of activity, and convulsions. Overdose victims should be taken to a hospital emergency room as soon as possible. ALWAYS bring the prescription bottle or container.
Special Information
Always take your entacapone dose together with your levodopa + carbidopa dose. If you forget a dose, take it as soon as you remember. If it is within 2 hours of your next dose, skip the dose you forgot and continue with your regular schedule.
This drug can cause dizziness, nausea, sweating, or fainting when rising quickly from a sitting or lying position, especially at the beginning of treatment.
Increased body movements and twitching, twisting, or uncontrolled tongue, lip, face, arm, or leg movement may occur. If this happens, your doctor may need to adjust your dose of levodopa + carbidopa.
Exercise caution when performing tasks, such as driving, that require coordination and concentration until your body has become accustomed to the effects of entacapone.
Gradually reducing the dose of entacapone decreases some drug side effects.
Rapid withdrawal can cause high fever, sweating, unstable blood pressure, stupor, and muscular rigidity. Patients who stop using entacapone should be monitored.
Entacapone can cause your urine to turn a brownish-orange color. This change is harmless.
Special Populations
Pregnancy/Breast-feeding: Entacapone causes birth defects, miscarriage and abortion in pregnant animals. When this drug is considered crucial by your doctor, its potential benefits must be weighed against its risks.
