Flecainide causes or worsens arrhythmias m 7% 0 people who take it; this, tks’ , imTeases with certain kinds of underlying heart disease and higher doses of the drug. Flecainide causes or worsens heart failure in about 5% of people taking it because it tends to reduce the force and rate of each heartbeat.
Flecainide is extensively broken down in the liver. People with poor liver function should not take flecainide unless the benefits clearly outweigh the risks.
Changes in the pH of urine may affect the effectiveness of flecainide.

Prescribed For
Infections of the lower respiratory system, sinuses, urinary tract, skin, bone and joints, lungs, and prostate; also prescribed for sexually transmitted diseases, prostatitis, infectious diarrhea, bronchitis, pneumonia, typhoid fever, anthrax, and traveler’s diarrhea. The eyedrops are used to treat ocular infections, the eardrops for ear infections.
General Information
Fluoroquinolone anti-infectives work against many organisms that traditional antibiotics have trouble killing. They do not work against the common cold, flu, or other viral infections. The fluoroquinolones were first used as treatment for urinary infections and then other uses developed over the years. The new uses depend on how well the specific drug penetrates different body tissues as well as on how they have been tested in the laboratory. Individual fluoroquinolones are not all equally effective in treating all infections.
Cautions and Warnings
Do not take a fluoroquinolone if you are allergic or sensitive to any of its ingredients, or to any drug in this group, or have had a reaction to related medications such as nalidixic acid. Severe, possibly fatal, allergic reactions can occur even after the very first dose. These reactions include cardiovascular collapse, loss of consciousness, tingling, swelling of the face or throat, breathing difficulties, itching, and rash. Stop taking the drug if you experience allergic symptoms and seek medical help at once.
Fluoroquinolones may cause increased pressure on parts of the brain, leading to convulsions and psychotic reactions. Other possiblp. tIWA include tremors, restlessness, lightheadedness, confusion, and hallucinations. Fluoroquinolones should be used with caution in people with head trauma, seizure disorders, or other nervous system conditions.
Moxifloxacin should not be used by people with liver disease.
Moxifloxacin should be avoided by people with heart rhythm problems or those taking drugs that can affect heart rhythm.
People with kidney disease require reduced dosage of these drugs, except in the case of moxifloxacin.
People taking fluoroquinolones may be unusually sensitive to the sun. Avoid the sun while taking this drug and for several days following therapy, even if you are using sunscreen.
People taking a fluoroquinolone may develop colitis that could range from mild to very serious. Contact your doctor if you develop diarrhea or cramps.
Fluroquinolones can worsen myasthenia gravis. Use with caution.
Prolonged fluoroquinolone use can lead to fungal overgrowth.
Patients taking a fluoroquinolone may experience ruptures of the shoulder, hand, Achilles tendon, or other tendons that may require surgery or lead to extended disability.
Possible Side Effects
Side effects are rarely serious.
♦ Common: nausea (most likely with ciprofloxacin and moxifloxacin), vomiting, and diarrhea (may be most likely with moxifloxacin and ofloxacin).
✓ Less common: dizziness, abdominal pain, headache, and liver inflammation.
✓ Rare: Rare side effects, including some severe drug reactions, can occur in almost any part of the body. In once-daily studies of ciprofloxacin eardrops, there were a few reports of nausea, formation of flaky scales, inflammation of the external ear, temporary hearing loss, ringing or buzzing in the ears, middle-ear inflammation, tremors, high blood pressure, and fungal infection. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Separate your fluoroquinolone dose from that of antacids, didanosine, iron supplements, or zinc by 2-6 hours. These drugs decrease the amount of fluoroquinolone absorbed. Moxifloxacin must be taken 4 hours before or 8 hours after antacids, iron, or zinc.
• Nitrofurantoin may antogonize norfloxacin’s antibacterial effects. Do not take these drugs together.
• Moxifloxacin can increase the risk of abnormal heart rhythms.
Combining this drug with astemizole, erythromycin, tricyclic
antidepressants, and antipsychotics increases the risk of ab-
normal heart rhythms associated with this drug.
• People taking drugs to correct abnormal heart rhythms should avoid Fluoroquinolones.
• Nonsteroidal anti-inflammatory drugs (NSAIDs) and anti-inflammatory drugs should not be combined with fluoroquinolones because of the increased risk of stimulation and seizures.
• Sucralafate reduces the amount of fluoroquinolone absorbed in the blood. Take sucralafate at least 6 hours after taking a fluoroquinolone.
• Probenecid may increase the risk of some fluoroquinolone side effects. Cimetidine may also increase fluoroquinolone blood levels.
• Fluoroquinolones (except moxifloxacin) may increase the effect of oral anticoagulant drugs such as warfarin. Your anticoagulant dosage may have to be reduced.
• Fluoroquinolones may increase the toxic effects of cy-
closporine (used for organ transplants) on your kidneys.
• Fluoroquinolones (except moxifloxacin) may increase theophylline blood levels and the risk of side effects.
• Azlocillin may increase the risk of ciprofloxacin side effects.
• Ciprofloxacin and norfloxacin may increase caffeine’s effects.
Food Interactions
Levofloxacin, lomefloxacin, and moxifloxacin may be taken with or without food. Take ofloxacin and norfloxacin at least 2 hours before or 2 hours after meals or antacids. Ciprofloxacin is best taken 1 hour before or 2 hours after meals, but may be taken with food. Dairy products and calcium-fortified orange juice interfere with the absorption of ciprofloxacin and should be avoided.

Brand Name
Dalmane
Type of Drug Benzodiazepine sedative.
Prescribed For
Insomnia and sleep disturbances.
General Information
Flurazepam is a member of the group of drugs known as benzodiazepines. Benzodiazepines work by a direct effect on the brain. They make it easier to go to sleep and decrease the number of times you wake up during the night. Flurazepam and quazepam remain in your bloodstream longer than other drugs in this class, thus resulting in the greatest incidence of morning “hangover.”
Cautions and Warnings
Do not use flurazepam if you are allergic or sensitive to any of its ingredients.
People with kidney or liver disease should be carefully monitored while taking flurazepam. Take the lowest possible dose to help you sleep.
People with respiratory disease may experience sleep apnea (intermittent cessation of breathing during sleep) while taking flurazepam.
Clinical depression may be increased by flurazepam, which can depress the nervous system. Intentional overdose is more common among depressed people who take sleeping pills than among those who do not.
Some people have experienced amnesia while taking flurazepam.
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 of drug dependence. Withdrawal symptoms include tremors, muscle cramps, insomnia, agitation, diarrhea, vomiting, sweating, and convulsions.
Tapering the drug when stopping may help prevent withdrawal symptoms. People with a history of seizures should be particuarly cautious when stopping use of this drug.
Possible Side Effects
V Common: drowsiness, headache, dizziness, talkativeness, nervousness, appip-henslon, poor muscle coordination, lightheadedness, daytime tiredness, muscle weakness, slowness of movement, hangover, and euphoria (feeling “high”).

Drug Interactions
• As with all benzodiazepines, the effects of flurazepam are enhanced if it is taken with an alcoholic beverage, antihistamine, sedative, barbiturate, anticonvulsant medication, antidepressant, or monoamine oxidase inhibitor antidepressant.
• Contraceptive drugs, cimetidine, disulfiram, and isoniazid may increase the effect of flurazepam by reducing the drug’s breakdown in the liver. Probenecid also increases flurazepam’s effects.
• Cigarette smoking, rifampin, and theophylline may reduce the effect of flurazepam on your body by increasing the rate at which it is broken down by the liver.
• Levodopa + carbidopa’s effectiveness may be decreased by flurazepam.
• Flurazepam may increase the amount of zidaw-adwie tan HIV drug—also known as pnenytoin, or digoxin in your WZWMTeam, increasing the chances of side effects.

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.
Child: not recommended.
Overdosage
Doses up to 4 times the recommended dose have been taken for 10 weeks without additional side effects. However, overdose victims should be taken to a hospital emergency room for observation. ALWAYS bring the prescription bottle or container.
Special information

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.
Special Populations
Pregnancy/Breast-feeding: ACE inhibitors can cause fetal injury or death. Women who are or might become pregnant should not take ACE inhibitors. Sexually active women of childbearing age who must take enalapril must use an effective contraceptive method to prevent pregnancy. If you become pregnant, stop taking the medication and call your doctor immediately.
Small amounts of enalapril pass into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors may be more sensitive to the effects of this drug due to age-related losses in kidney or liver function.

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.
Entacapone passes into the breast milk of animals but no information on humans is available. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors may take this drug without special precaution.

Generic Name
Doxazosin (dok-SAY-zoe-sin) In
Brand Names
Cardura. Cardura XL
Type of Drug Antihypertensive.
Prescribed For
High blood pressure and benign prostatic hyperplasia (BPH); also used with digoxin and diuretic drugs to treat congestive heart failure.
General Information
Doxazosin mesylate and other alpha-adrenergic blocking agents, or alpha blockers, reduce blood pressure by dilating (widening) blood vessels. They achieve this effect by blocking nerve endings known as alpha, receptors. The maximum blood-pressurelowering effect of doxazosin is seen between 2 and 6 hours after taking a dose. In BPH treatment, doxazosin works by relaxing smooth muscles in the prostate and neck of the bladder. Doxazosin helps the symptoms of BPH, and taking it for several years may eliminate the need for surgery or allow the use of a less invasive type of surgery. Doxazosin’s effect lasts for 24 hours. It is mostly broken down in the liver; little passes out of the body via the kidneys.
Doxazosin may slightly reduce cholesterol levels and improve the ratio of high-density lipoprotein (HDL)—”good” cholestemAand low-density lipoprotein (ILDL}—”bad cholesterol”—a positive step for peQ¢kp_%Aln a blood-cholesterol problem.
Cautions and Warnings
Do not take doxazosin if you are allergic or sensitive to any of its ingredients or to any alpha blocker.
Doxazosin may cause dizziness and fainting, especially the first few doses. This is known as a first-dose effect, which can be minimized by limiting the first dose to 1 mg at bedtime. First-dose effects occur in about i % of people taking an alpha blocker and may recur if the drug is stopped for a few days and then started
again.
Doxazosin should be taken with caution if you have liver
disease.
White-blood-cell counts may be slightly decreased in people
taking doxazosin.
Rarely, alpha blockers, including doxazosin, have led to pri-
apism (painful and prolonged erection). Call your doctor immediately if this happens. If not treated promptly, this condition can lead to impotence.
Possible Side Effects
✓ Most common: headache, dizziness, and weakness.
♦ Less common: heart palpitations, abnormal heart rhythms, chest pain, nausea, diarrhea, constipation, abdominal pain or discomfort, gas, breathing difficulties, nosebleed, sore throat, runny nose, muscle or joint pain, visual disturbances, conjunctivitis (pinkeye), ringing in the ears, fainting, depression, decreased sex drive or sexual function, tingling in the hands or feet, nervousness, tiredness, anxiety, sleeplessness, poor muscle coordination, muscle stiffness, poor bladder control, frequent urination, itching, rash, sweating, fluid retention, facial swelling and flushing, and back, neck, shoulder, arm, or leg pain.
✓ Rare: vomiting, dry mouth, sinus irritation, bronchitis, cold or flu symptoms, worsening of asthma, coughing, hair loss, weight gain, and fever. Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Doxazosin may interact with beta blockers to ‘increase the risk of dizziness or fa:kv%1)g alter the first dose of doxazosin.
• TW-1 UDOd-pressure-lowering effect of doxazosin may be reduced by indomethacin.
• When taken with other blood-pressure-lowering drugs, dox-
azosin produces a severe reduction of blood pressure.
• The blood-pressure-lowering effect of clonidine may be reduced by doxazosin.
Doxazosin should be taken with caution in combination with clarithromycin, ketoconazole, and itraconazole.
Food Interactions None known.
Usual Dose
Adult: 1 mg morning or evening to start; may be increased to a total of 16 mg, taken once a day. Extended-release tablets-4 mg once daily at breakfast; may be increased to a total of 8 mg. Do not chew, cut, or crush extended-release tablets.
Child: not recommended.
Overdosage
Overdose may produce drowsiness, poor reflexes, and very low blood pressure. Overdose victims should be taken to a hospital emergency room at once. ALWAYS bring the prescription bottle or container.
Special Information
Take doxazosin exactly as prescribed. Do not stop taking it unless directed to do so by your doctor. Avoid over-the-counter drugs that contain stimulants because they may increase your blood pressure.

Generic Name
Doxercalciferol (dox-er-kal-Sffl-fer-ahl)
Brand Names
Drisdol Liquid Hectorol Capsules
Type of Drug
Vitamin D supplement.
Prescribed For
Elevated parathyroid hormone levels in patients undergoing kidney dialysis.
General Information
Doxercalciferol is a synthetic form of vitamin D that is processed in the body to form active vitamin D. Vitamin D, along with parathyroid hormone, are key elements of the calcium-regulating system in the body. Normally, your body releases parathyroid hormone if blood calcium levels are too low. Parathyroid hormones move calcium from the place where it is found in greatest quantity—your bones—into the bloodstream. This can have disastrous effects for a wide variety of body functions where calcium is crucial including muscle contraction, nervous system function, bone fragility, and blood clotting. Doxercalciferol helps to stabilize the system and normalize parathyroid hormone levels that can be artificially elevated in dialysis patients.
Cautions and Warnings
Do not use doxercalciferol if you are allergic or sensitive to any of its ingredients.
Do not take any other Vitamin D supplement while taking this dwg.
People with a tendency toward high calcium or vitamin D levels should not take doxercalciferol.

Generic Name
Dronabinol (droe-Mla-ih,bl)
Brand Name Marino)
Type of Drug Antinauseant.
Prescribed For
Nausea and vomiting associated with cancer chemotherapy, and appetite stimulation and weight-loss prevention in people with acquired immunodeficiency syndrome (AIDS).
General Information
Dronabinol is a legal form of marijuana. The psychoactive chemical in marijuana is delta-9-THC. Dronabinol has all of the psychological effects of marijuana and is therefore considered to be a highly abusable drug. It can cause personality changes, feelings of detachment, hallucinations, and euphoria (feeling “high”). Younger adults have reported a greater success rate with dronabinol, probably because they are better able to tolerate these effects.
Most people start taking dronabinol while in the hospital so their response to the drug and its possible adverse effects can be monitored. Dronabinol has also been studied as a glaucoma treatment.
Cautions and Warnings
Do not take dronabinol if you are allergic or sensitive to any of its ingredients, to marijuana, or to sesame oil.
Dronabinol should not be used to treat nausea and vomiting caused by anything other than cancer chemotherapy.
Dronabinol should be used with caution in those with a history of seizure disorders or substance abuse.
Dronabinol has a profound effect on mental states; it will impair your ability to operate complex equipment or engage in any activity that requires intense concentration, sound judgment, or coordination—such as driving a car.
Dronabinol produces withdrawal symptoms when the drug is stopped. These may develop within 12 hours of the drug’s discontinuation and include restlessness, sleeplessness, and irritability. Within a day after the drug has been stopped, stuffy nose, hot flashes, sweating, loose stools, hiccups, or appetite loss may occur. The symptoms usually subside within a few days,
Dronabinol should be used with caution by people with heart disease or high blood pressure. Dronabinol should be used with caution by people with a manic-depressive or schizophrenic history because it may aggravate the underlying disease.
Possible Side Effects
V Most common: drowsiness, euphoria, dizziness, anxiety, muddled thinking, perceptual difficulties, poor coordination, irritability, a separation in time and space, depression, weakness, sluggishness, nausea and vomiting, headache, hallucinations, memory lapses, loss of muscle coordination, unsteadiness, paranoia, depersonalization, disorientation, confusion, rapid heartbeat, and dizziness when rising from a sitting or lying position.
♦ Less common: difficulty talking or slurred speech, facial flushing, excessive perspiration, nightmares, ringing or buzzing in the ears, fainting, diarrhea, loss of bowel control, and muscle pain.
Drug Interactions
• Dronabinol increases the effects of alcohol, sleeping pills, sedatives, and other depressants. It also enhances the effects of psychoactive drugs including tricyclic antidepressants, amphetamines, cocaine, and other stimulants.
• Dronabinol may increase the effects of fluoxetine and disulfiram.
• The effects of theophylline drugs are reduced by dronabinol.
• Combining dronabinol and antihistamines or anticholinergic drugs may cause either rapid heartbeat or excessive drowsiness.

Alzide Novo-Spirozine Spirozide
Type of Drug
Diuretic that increases urination).
Prescribed For Hypertension (high blood pressure) or any condition where it is de-
sirable to eliminate excess water from the body. General Information
Dyazide combines a thiazide diuretic and a potassium-sparing diuretic. The latter, triamterene, helps the body retain potassium while producing a diuretic effect. This balances the other ingredient, hydrochlorothiazide, which normally causes a loss of potas- sium. Different products contain differing concentrations of these 2 drugs. Dyazide should be used only when you need its exact proportion of ingredients, and should not be used for initial therapy of hypertension or edema. It may be used alone or with other anti hypertensive drugs such as beta blockers. Dosage adjustment may be necessary.
Cautions and Warnings
Do not use dyazide if you are allergic or sensitive to any of its ingredients or to any sulfa drug or if you have a history of allergy.
Do not use Dyazide if you have nonfunctioning kidneys, bronchial asthma, or hyperkalemia (high blood potassium levels).
Do not combine any potassium supplement and Dyazide without your doctor’s knowledge. Dyazide may reduce blood levels of sodium and potassium and raise blood calcium levels.
Dyazide should be used with caution in people with diabetes, liver disease, or an electrolyte imbalance.
Possible Side Effects
♦ Most common: appetite loss, drowsiness, lethargy, head-
ache, gastrointestinal upset, cramping, and diarrhea.
V Less common: rash—possibly severe, mental confusion, fever, feeling unwell, impotence, bright red tongue, burnt”g sensation in the tongue, tingling in the toes and fingers, restlessness, anemia or other effects on blood components, increased sensitivity to sunlight, and dizziness when rising quickly from a sitting position. Dyazide may also produce muscle spasms, gout, weakness, and blurred vision.
Drug Interactions
other blood pressure
• Dyazide increases the effect of
drugs. This is why other blood-pressure drugs are often prescribed with Dyazide, but dosage adjustments may be required.
• Combining Dyazide and digitalis drugs, amphotericin B, or adrenal corticosteroids increases the risk of body-fluid imbalance. If you are taking insulin or an oral antidiabetic drug and begin taking Dyazide, the insulin or antidiabetic dosage may have to be modified.
• Dyazide may increase the risk of allopurinol side effects.
• Dyazide may decrease the effects of oral anticoagulant (blood-thinning) drugs.
• Antigout drug dosage may have to be modified since Dyazide raises uric-acid levels.
• Dyazide may prolong the effects of chemotherapy drugs on reducing white-blood-cell counts.
• Dyazide may increase the effects of diazoxide, which may lead to symptoms of diabetes.
• Dyazide should not be taken with loop diuretics because the combination can lead to an extreme diuretic effect and an extreme effect on blood-sodium levels.
• Dyazide may increase the effect of vitamin D, which may cause high blood-calcium levels.
• Propantheline and other anticholinergics may increase the diuretic effect of Dyazide.
• Lithium carbonate taken with Dyazide should be monitored carefully by a doctor due to an increased risk of lithium side effects.
• Cholestyramine and colestipol prevent Dyazide from being absorbed. Dyazide should be taken at least 2 hours before cholestyramine or colestipol.
• Methenamine and other urinary agents may reduce the effect of Dyazide.
• Some nonsteroidal anti-inflammatory drugs (NSNDs), particularly indomethacin, may reduce the effect of Dyazide. Sulindac, another NSAID, may increase its effect.
