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
Estrogens may be taken with food to reduce nausea and upset stomach. Avoid drinking grapefruit juice if you are taking this drug.

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
Etanercept (eh-TAN-er-sept)
Brand Name Enbrel
Type of Drug
Immune system modulator.
Prescribed For
Rheumatoid arthritis, juvenile rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, and psoriasis.
General Information
Etanercept binds to a specific protein in the body known as tumor necrosis factor (TNF) and blocks it from interacting with cell surfaces. TNF is involved in normal inflammatory and immune responses and the inflammatory processes of rheumatoid arthritis, juvenile rheumatoid arthritis, and other conditions. Etanercept can also interfere with biological actions that are either caused or regulated by TNF.
Cautions and Warnings
Do not use etanercept if you are allergic or sensitive to any of its ingredients.
Serious infections and malignancies are possible in people using etanercept because of its ability to suppress the immune response. This may be more common in people with other conditions that predispose them to infections such as advanced or uncontrolled diabetes.
Levels of blood platelets and some white blood cells may be reduced in rare cases, leading to persistent fever, bruising, bleeding, and pale skin. Contact your doctor if any of these symptoms develop.
Etanercept may increase the risk of some nervous system disorders including multiple sclerosis.
Etanercept may cause or worsen congestive heart failure.
In rare cases people taking etanercept have developed a lupus-like syndrome which may disappear when the drug is discontinued.

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

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.

Generic Name
Cholestyramine (kol-es-TYE-rah-meen) 0
Brand Names
LoCHOLEST Questran
LoCHOLEST Light Questran Light Prevalite
The information in this profile also applies to the following drugs:
Generic Ingredient: Colesevelam Hydrochloride WelChol
Generic Ingredient: Colestipol Hydrochloride Colestid
Type of Drug
Anti -hyperli pidemic (blood-fat reducer).
Prescribed For
High blood-cholesterol levels; generalized itching associated with bile duct obstruction—cholestyramine only; colitis; digitalis or thyroid overdose; and pesticide poisoning.
General Information
Cholestyramine resin lowers blood-cholesterol levels by absorbing bile acids in the bowel. Since the body uses cholesterol to make the bile acids—needed to digest fat—fat digestion can only continue by making more bile acid from blood cholesterol. This results in lower blood-cholesterol levels 4-7 days after starting cholestyramine.
Cholestyramine w3Cks entirely Within the bowel and is never absorbed into the bloodstream. Though usually given 3-4 times a day, there appears to be no advantage to taking it more often than twice a day. The cholesterol-lowering effect of cholestyramine may be increased when it is taken with an HMG-CoA inhibitor or nicotinic acid. In some kinds of hyperlipidemia, colestipol may be more effective in lowering total blood cholesterol than clofibrate.
Cautions and Warnings
Do not use cholestyramine if you are allergic or sensitive to any of its ingredients or if your bile duct is blocked. The powder form should not be taken dry; doing so may result in the inhalation of powder into your lungs or a clogged esophagus.
If you are being treated for hypothyroidism, diabetes, kidney or blood vessel disorder, obstructive liver disease, or alcholism, consult your doctor before taking cholestyramine.
Cholestyramine may cause or worsen constipation and hemorrhoids. Most constipation is mild, but some people may need to stop the medication or take less of it.
Possible Side Effects
✓ Most common: constipation, which may be severe and in rare cases result in bowel impaction. Hemorrhoids may be worsened.
♦ Less common: abdominal pain and bloating, and bleeding disorders or black-and-blue marks due to interference with the absorption of vitamin K, a necessary factor in the blood clotting process. One person developed night-blindness because the medication interfered with vitamin A absorption into the blood. Other side effects include belching, gas, nausea, vomiting, diarrhea, heartburn, and appetite loss. Your stool may have an unusual appearance because of a high fat level.
✓ Rare: Rare side effects can affect your mouth, stomach and intestines, muscles and joints, mental status, urinary tract, and breathing. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
O Cholestyramine interferes with the absorption of virtually all oral drugs, including acetaminophen, amiodarone, aspirin, cephalexin, chenodiol, clindamycin, clofibrate, contraceptive drugs, corticosteroids, diclofenac, iopanoic acid, iron, digitalis drugs, furosemide, gemfibrozil, glipizide, hydrocortisone, imipramine (an antidepressant), methyldopa, mycophenolate, nicotinic acid, penicillin, phenobarbital, phenytoin, piroxicam, propranolol, tetracycline, thiazide diuretics, thyroid drugs, tolbutamide, trimethoprim, ursodiol, warfarin and other anticoagulant (blood-thinning) drugs, and vitamins A, D, E, and K. Take other medications at least 1 hour before or 4-6 hours after taking cholestyramine.
Food Interactions
Take this medication before meals. The powder may be mixed with soda, water, juice, cereal, or pulpy fruits, such as applesauce or crushed pineapple. Cholestyramine bars should be thoroughly chewed and taken with plenty of fluids. Colestipol pills are swallowed whole.

Special Information
Do not swallow the granules or powder in their dry form. Prepare each packet of powder by mixing it with soup, cereal, or pulpy fruit or by adding the powder to a 6-oz. glass of liquid, such as a carbonated beverage. If some of the drug sticks to the sides of the glass, rinse it with liquid and drink the remainder.
Constipation, gas, nausea, and heartburn may occur and then disappear with continued use of this medication. If constipation is a problem, your doctor may recommend drinking more fluids and taking a fiber supplement. Call your doctor if these side effects persist or if you develop unusual problems such as bleeding from the gums or rectum.
If you miss a dose of cholestyramine, skip it and continue with your regular scheduke. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: While cholestyramine does not affect the fetus directly, it may prevent the absorption of vitamins A, D, and E and other nutrients essential to the fetus’ proper development–even when you take, a prenatal vitamin supplement.
When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
Cholestyramine is not absorbed into the body. However, reduced absorption of vitamins A, D, and E and other nutrients may make your milk less nutritious. Nursing mothers who must take cholestyramine should use infant formula.

Generic Name
Chlordiazepoxide (klor-dye-az-uh-PDX-ide) 91
Brand Name
Librium
Type of Drug Benzodiazepine sedative.
Prescribed For
Anxiety, tension, fatigue, agitation, and withdrawal symptoms of alcoholism; also prescribed for irritable bowel syndrome and panic attacks.
General Information
Chlordiazepoxide is a member of the group of drugs known as benzodiazepines.
Benzodiazepines work by a direct effect on the brain. They can relax you and make you more tranquil or sleepier, or they can slow nervous system transmissions in such a way as to act as an anticonvulsant. Many doctors prefer benzodiazepines to other drugs that can be used to similar effect because they tend to be safer, have fewer side effects, and are usually as effective, if not more so.
Cautions and Warnings
Do not take chlordiazepoxide if you are allergic or sensitive to any of its ingredients or to another benzodiazepine, including clonazepam.
Chlordiazepoxide can aggravate narrow-angle glaucoma, but you may take it if you have open-angle glaucoma and are receiving therapy for it.
Other condkjo(\SiVN\,NhjCb chlordiazepoxide should be used with caution are severe depression, especially with suicidal tendencies, severe lung disease, sleep apnea (intermittent cessation of breathing during sleep), liver disease, drunkenness, and kidney disease.
Chlordiazepoxide should not be taken by psychotic patients because it is not effective for them and can trigger unusual excitement, stimulation, and rage. It has also produced similar reactions among hyperactive and aggressive pediatric patients.
Chlordiazepoxide is not intended for more than 3-4 months of continuous use. Your condition should be reassessed before continuing chlordiazepoxide beyond that time.
Chlordiazepoxide may be addictive. Drug withdrawal may develop if you stop taking it after only 4 weeks of regular use, but is more likely after longer use. It may start with anxiety and progress to tingling in the hands or feet, sensitivity to bright light, sleep disturbances, cramps, tremors, muscle tension or twitching, poor concentration, flu-like symptoms, fatigue, appetite loss, sweating, and changes in mental state.
Dosage of chlordiazepoxide should be decreased gradually over 4-8 weeks after prolonged use.
Possible Side Effects

Drug Interactions
• Chlordiazepoxide is a central-nervous-system depressant. Avoid alcohol, other sedatives, narcotics, barbiturates, mono-amine oxidase inhibitor and other antidepressants, and antihistamines. Taking chlordiazepoxide with these drugs may result in excessive depression, tiredness, sleepiness, breathing difficulties, or related symptoms.
• Smoking may reduce the effectiveness of chlordiazepoxide by increasing the rate at which it is broken down by the body.
• The effects of chlordiazepoxide may be prolonged when it is
taken with cimetidine, contraceptive drugs, disulfiram, flu-
oxetine, isoniazid, ketoconazole, metoprolol, probenecid,
propoxyphene, propranolol, rifampin, or valproic acid.
• Theophylline may reduce chlordiazepoxide’s sedative effects.
• If you take antacids, separate them by at least 1 hour from your chlordiazepoxide dose to prevent them from interfering with the passage of chlordiazepoxide into the bloodstream.
• Chlordiazepoxide may increase blood levels of digoxin and the chances for digoxin toxicity.
• Levodopa + carbidopa’s effectiveness may be reduced by chlordiazepoxide.
• Phenytoin blood concentrations may be increased when taken with chlordiazepoxide, resulting in possible phenytoin toxicity.
Food Interactions
Chlordiazepoxide is best taken on an empty stomach but may be taken with food if it upsets your stomach.
Usual Dose
Adult: 5-100 mg a day. This range is due to individual response related to age, weight, disease severity, and other characteristics.
Child (age 6 and over): may be given if deemed appropriate by a doctor. Starting dose-5 mg 2-4 times a day. Maintenance dose—up to 30 mg a day for some children, but must be individualized to obtain maximum benefit.
Child (under age 6): not recommended.
Overdosage
Symptoms of overdose are confusion, sleepiness, poor coordination, lack of response to pain such as a pin prick, loss of reflexes, shallow breathing, low blood pressure, and coma. The victim should be lakes to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Chlordiazepoxide can cause tiredness, drowsiness, inability to concentrate, or similar symptoms. Be careful if you are driving, operating machinery, or performing other activities that require concentration.
If you forget a dose of chlordiazepoxide, 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
Pregnancy/Breast-feeding: Chlordiazepoxide may cause birth defects if taken during the first 3 months of pregnancy. Avoid chlordiazepoxide while pregnant.
Chlordiazepoxide may pass into breast milk. Nursing mothers who must take chlordiazepoxide should use infant formula.
Seniors: Seniors, especially those with liver or kidney disease, are more sensitive to the effects of chlordiazepoxide and generally require smaller doses to achieve the same effect.

Alprazolam
July 16, 2009 | Leave a Comment
Generic Name
Alprazolam (al-PRAY-zoe-lam) CGI
Brand Names
Niravam Xanax Xanax XR Type of Drug
Benzodiazepine sedative.
Prescribed For
Generalized anxiety disorder and anxiety associated with depression; panic disorder with or without agoraphobia.
General Information
Alprazolam is a member of a group :)f drugs known as benzodiazepines. Benzodiazepines directly affect the brain. They can relax you and make you more tranquil or sleepier, or they can slow nervous system transmissions in such a way as to act as an anticonvulsant. Many doctors prefer benzodiazepines to other drugs that can be used to similar effect because they tend to be safer, have fewer side effects, and are usually as effective, if not more so.
Cautions and Warnings
Do not take alprazolam if you know you are allergic or sensitive to it or to another benzodiazepine drug, including clonazepam.
Alprazolam can aggravate narrow-angle glaucoma, but you may take it if you have open-angle glaucoma and are receiving therapy for it.
Other conditions where alprazolam should be avoided are: severe lung disease, sleep apnea (intermittent cessation of breathing during sleep), liver disease, drunkenness, and kidney disease. In each of these conditions, the depressive effects of alprazolam may be enhanced or could be detrimental to your overall condition.
Alprazolam should not be taken by psychotic patients because it is not effective for them and can trigger unusual excitement, stimulation, and rage.
Alprazolam is meant to be used for no more than 3-4 months in a row. Your condition should be reassessed before continuing your medicine beyond that time.
Alprazolam may be addictive. When used to treat panic disorder, alprazolam is frequently prescribed in doses exceeding 4 mg a day. Studies show that these higher doses may cause physical and emotional dependence, making it very difficult to stop taking the drug. Drug withdrawal may develop if you stop taking it after only 4 weeks of regular use but is more likely after longer use and at higher doses. It may start with anxiety and progress to tingling in the hands or feet, sensitivity to bright light, sleep disturbances, cramps, tremors, muscle tension or twitching, poor concentration, flu-like symptoms, fatigue, appetite loss, sweating, and changes in mental state. Severe withdrawal symptoms may include seizures.
Your dosage should be reduced gradually (0.5 mg decrease every 3 days) to prevent drug withdrawal symptoms.
Possible Side Effects
V Most common: mild drowsiness during the first few days of therapy. Weakness and confusion may occur, especially in seniors and in those who are sickly. If these effects persist, contact your doctor.
V Less common: depression, lethargy, disorientation, headache, inactivity, slurred speech, stupor, dizziness, tremors, constipation, dry mouth, nausea, inabilityto control urination, Possible Side Effects (continued)
sexual difficulties, irregular menstrual cycle, changes in heart rhythm, low blood pressure, fluid retention, blurred or double vision, itching, rash, hiccups, nervousness, inability to fall asleep, and occasional liver dysfunction. If you experience any of these symptoms, stop taking the medicine and contact your doctor immediately.
V Rare: withdrawal seizures. 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

• The effects of some benzodiazepines may be decreased by rifampin.
• Theophyllines may reduce alprazolam’s sedative effects.
• If you take antacids, separate them from your alprazolam dose by at least 1 hour to prevent them from interfering with the absorption of alprazolam into the bloodstream.
• Alprazolam may raise digoxin blood levels and the chances of digoxin toxicity.
• The effect of levodopa + carbidopa may be decreased if it is taken together with alprazolam.
• Combining alprazolam with phenytoin may increase phenytoin blood concentrations and the chances of phenytoin toxicity.

Alitretinoin
July 16, 2009 | Leave a Comment
Generic Name
Alitretinoin (al-ih-TRET-in-oin)
Brand Name
Panretin
Type of Drug Retinoid.
Prescribed For
Skin lesions of Kaposi’s sarcoma (KS).
General Information
Alitretinoin binds to and activates retinoid receptors in human cells. Once activated, these receptors help stimulate the body’s natural mechanisms for limiting tissue growth—in this case, the growth of KS cells. KS lesions, which are primarily associated with human immunodeficiency virus (HIV), can respond to alitretinoin in as little as 2 weeks, but most people do not start to see results for 48 weeks or, in some cases, 14 weeks or more.
Cautions and Warnings
Do not use alitretinoin if you are allergic or sensitive to retinoids or to any of its ingredients.
Alitretinoin is applied to individual KS lesions. It does not treat systemic KS or prevent new KS lesions from forming.
People requiring systemic KS treatment (those who have developed more than 10 new KS lesions within a month) should not use alitretinoin.
People with swollen lymph glands, KS that affects the lungs or other major organ involvement should not use alitretinoin.
Possible Side Effects .
✓ Most common: rash and burning pain at application site.
♦ Common: itchy, flaking, peeling, cracking, oozing, swelling, and inflammation at application site.
Drug Interactions
• Do not use insect repellant products that contain DEET, a widely used chemical repellant. Alitretinoin increases DEET toxicity.
Usual Dose
Adult: Apply 2-4 times a day to KS skin lesions. Seniors should use this drug with caution.
Child: not recommended.
Overdosage
Little is known about the effects of accidental ingestion. 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
Apply enough alitretinoin gel to cover the entire skin lesion. Allow the gel to dry for 3-5 minutes before covering the area with clothing. Avoid showering, bathing, or swimming for at least 3 hours.
If you use a bandage or dressing, be sure it is not tight and that air can circulate freely over the area.
Avoid applying alitretinoin to unaffected skin because it may be irritated by the drug. Avoid applying near the nose, eyes, or mouth.
Alitretinoin contains alcohol. Always keep it away from any open flame.
Retinoids can cause unusual sensitivity to the sun. While this has not been seen with alitretinoin, you should avoid prolonged exposure to the sun or use sunscreen while taking this drug.
If you forget a dose, apply it as soon as you remember. If it is almost time for your next dose, apply the forgotten dose and then space the rest of your doses throughout the day. Continue with your regular schedule the next day.
Special Populations
PregnancylBreast-feeding., Alitretinoin can harm the fetus when sufficient levels of the drug are present in the mother’s bloodstream, but it is not known if these levels are achieved during routine use of alitretinoin. Women who are or might be pregnant should only use this drug after discussing its potential benefits and risks with their doctors.
It is not known if alitretinoin passes into breast milk. Nursing mothers who must use alitretinoin should use infant formula.
Seniors: There is no information on use of alitretinoin by seniors. Seniors should use it with caution.

Generic Ingredients: Albuterol + 1pratropium Bromide Combivent DuoNeb
The:nformation in this profile also applies to the following drugs:
Generic Ingredient: Levalbuterol Xopenex
Generic Ingredient., Pirbuterol Maxair
*Some products in this brand-name group are alcohol- or sugar-free. Consult your pharmacist.
Type of Drug Bronchodilator.
Prescribed for
Bronchospasm associated with asthma or other obstructive pulmonary diseases, or induced by exercise.
General Information
Albuterol is similar to other bronchodilator drugs, such as metaproterenol and isoetharine, but it has a weaker effect on nerve receptors in the heart and blood vessels; therefore, it is somewhat safer for people with heart conditions. Levalbuterol is a special form of albuterol that carries a lower risk of side effects.
Cautions and Warnings
Do not use Albuterol if you are allergic or sensitive to any of its ingredients. Albuterol should be used with caution by people with a history of angina pectoris (a condition characterized by brief attacks of chest pain), heart disease, irregularities in heart beat, high blood pressure, stroke or seizure, diabetes, thyroid disease, prostate disease, or glaucoma. Excessive use of albuterol inhalants may worsen asthma or other respiratory conditions, and may increase breathing difficulties rather than relieve them. In the most extreme cases, people have had heart attacks after using excessive amounts of inhalant.
Possible Side Effects
V Most common: worsening of asthma, ear infection, upper respiratory infection, stuffy nose, dizziness, headache, nausea, vomiting, and muscle cramps.
♦ Less common: angina, abnormal heart rhythms, rapid heartbeat and heart palpitations, allergic reaction, fever, and tremors.
Drug Interactions
• Albuterol’s effects on the cardiovascular system may be increased by monoamine oxidase inhibitor (MA01) and tricyclic antidepressants. These drugs should not be administered together or within 2 weeks of discontinuation of MAOls or tricyclic antidepressants.
• Beta-blocking drugs such as propranolol not only block the effects of albuterol but may cause severe bronchospasm in people with asthma.
• Albuterol may reduce the amount of digoxin in the blood of people taking both drugs. Digoxin dose adjustment may be required.
• Albuterol may exacerbate certain effects of non-potassium sparing diuretics (loop or thiazide diuretics).
Food Interactions
Albuterol tablets are more effective when taken on an empty stomach-1 hour before or 2 hours after meals—but can be taken with food if they upset your stomach.
Usual Dose
Albuterol and Pirbuterol Inhalation
Adult and Child (age 4 and over): 1-2 puffs every 4-6 hours. Asthma triggered by exercise may be prevented by taking 2 puffs 15 minutes before exercising.
Albuterol Inhalation Solution
Child (age 2-12): starting dose-0.63 mg or 1.25 mg 3 or 4 times a day. Deliver over 5-15 minutes by nebulizer.
Levalbuterol Inhalation Solution
Adult and Child (age 12 and over): 0.63 mg 3 times a day every 6-8 hours. Some people may benefit from 1.25 mg at each dose. Deliver over 5-15 minutes by nebulizer.
Child (age 6-11): 0.31 mg 3 times a day every 6-8 hours, by nebulizer.
Albuterol Inhalation Aerosol
Adult and Child (age 4 and over): 2 inhalations every 4-6 hours. Adults and children age 4 and over may prevent asthma brought on by exercise by inhaling twice 15 minutes before exercising.
Albuterol Sustained-Release Tablets
Adult and Child (age 12 and over): 4-8 mg every 12 hours. Dosage may be cautiously increased to a maximum of 32 mg a day. People being switched from regular to sustained-release tablets generally take the same dosage per day, in fewer tablets—for example, a 4-mg tablet every 12 hours (1 dose) instead of a 2-mg tablet every 6 hours (2 doses).
Child (age 6-12): 4 mg every 12 hours.
Overdosage
Overdose of albuterol inhalation usually results in exaggerated side effects, including chest pain and high blood pressure. People who inhale too much albuterol should see a doctor. Overdose of albuterol tablets may lead to changes in heart rate, palpitations, unusual heart rhythm, chest pain, high blood pressure, fever, chills, cold sweats, nausea, vomiting, and dilation of the pupils. Convulsions, sleeplessness, anxiety, and tremors may also develop, and the victim may collapse. If the albuterol overdose was taken within the past 1/2 hour, give the victim syrup of ipecac to induce vomiting. Do not give ipecac if the victim is unconscious or convulsing. If symptoms have already begun to develop, the victim may need to be taken to a hospital emergency room. Call for instructions, and ALWAYS bring the prescription bottle or container.
Special Information
If you are inhaling albuterol, be sure to follow the inhalation instructions that come with the product. The drug should be inhaled during the second half of your inward breath, since this will allow it to reach deeper into your lungs. Wait about 1-2 minutes between inhalations. Do not inhale albuterol if you have food or anything else in your mouth.
Do not take more albuterol than your doctor prescribes. Taking more than you need can worsen your symptoms. If your condition worsens after taking your medicine, call your doctor at once and stop taking it.
Call your doctor immediately if you develop chest pain, palpitations, rapid heartbeat, muscle tremors, dizziness, headache, facial flushing, or urinary difficulty, or if you continue having breathing difficulties after taking the medicine.
Do not crush or chew the extended-release tablets.
If you forget a dose of albuterol, take it as soon as you remember. If it is almost time for your next dose, skip the one you forgot. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: When used during childbirth, albuterol can slow or delay natural labor. It can cause rapid heartbeat and high blood sugar in the mother and rapid heartbeat and low blood sugar in the baby. Albuterol also causes birth defects in animal studies. When your doctor considers this drug crucial, its benefits must be cautiously weighed against its risks.
It is not known if albuterol passes into breast milk. Nursing mothers who must take it should use infant formula.
Seniors: Seniors with cardiovascular disease should use albuterol with caution.
