General Information
Donnatal is a mild antispasmodic sedative. Its principal action is to counteract the effect of acetylcholine, an important neurohormone. Donnatal is used only to relieve symptoms. not to treat the underlying condition, and there is considerable doubt among medical experts that this drug lives up to its claims. In addition to the brand names listed above, there are about 50 other anticholinergic combinations with similar properties. All are used to relieve cramps and all are about equally effective. Some have additional ingredients to reduce or absorb excess gas in the stomach, to coat the stomach, or to control diarrhea.

Drug Interactions
• Although Donnatal contains only a small amount of phenobarbital, it is wise to avoid alcohol or other sedative drugs. Although unlikely, phenobarbital interactions are possible with anticoagulants, adrenal corticosteroids, narcotics, sleeping pills, digitalis or other cardiac glycosides, and antihistamines.
• Some phenothiazine drugs, sedatives, tricyclic antidepressants, and narcotics may increase the side effects of the atropine sulfate ingredient in Donnatal, causing dry-mouth, urinary difficulties, and constipation.

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.
Doxazosin may cause dizziness, headache, and drowsiness, especially 2-6 hours after you take your first dose, although these effects can persist after the first few doses. Use caution when getting up from a sitting or lying position.
Call your doctor if you develop severe dizziness, heart palpitations, or any bothersome or persistent side effect.
Wait 12-24 hours after taking your first dose of doxazosin before driving or doing anything that requires concentration. Take your dose at bedtime to minimize this problem.
If you forget a dose, take it as soon as you remember. If it is almost time for your next dose, skip the dose you forgot and coT)- tinue with your regular schedule. Do R(ak%’Ke a double dose.

Pregnancy/Breast-feeding: The safety of using doxazosin during pregnancy is not known, although animal studies have shown that alpha blockers may affect fetal development. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
Small amounts of doxazosin pass into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors, especially those with liver disease, may be more sensitive to the effects and side effects of doxazosin.
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.
Before taking this medication, tell your doctor if you have liver disease. You may not be able to take doxercalciferol, or you may require a dosage adjustment or special monitoring during treatment.
Dialysis patients experience increases in blood calcium and phosphate while taking this drug.
Drug Interactions
• Do not take antacids that contain magnesium while you are taking doxercalciferol.
• Cholestyramine may reduce the absorption of doxercalciferol.
• Prolonged use of mineral oil may reduce the absorption of doxercalciferol.
• Do not combine any other over-the-counter or prescription medicines, or vitamin supplements with doxercalciferol without first talking with your doctor.
• The following medicines can slow the transformation of doxercalciferol to its active form in the body, reducing its effectiveness: ketoconazole, erythromycin, delaviridine, indinavir, nelfinavir, ritonavir, amiodarone, aprepitant, chloramphenicol, cimetidine, ciprofloxacin, clarithromycin, diltiazem, fluconazole, fluvoxamine, gestodene, itraconazole, mifepristone, nefazodone, norfloxacin, mibefradil, and verapamil.
• The following drugs can increase the breakdown of doxercalciferol in the liver, possibly reducing its effectiveness: efavirenz, nevirapine, barbiturates, carbamazepine, glucocorticoids, modafinil, phenobarbital, phenytoin, rifampin, St. John’s wort, oxcarbazepine, pioglitazone, and rifabutin. Dosage adjustment may be needed.
• Digoxin may cause symptoms of alcohol intolerance when combined with disulfiram or mettot)idazole.

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.
Food Interactions
This drug may be taken without regard to food or meals; as an appetite stimulant, it is often taken before meals.
Usual Dose
Antiemetic: 5 mg 1-3 hours before starting chemotherapy treatment and repeated every 2-4 hours after treatment, for a total of 4-6 doses a day. Dosage may be increased up to 15 mg per dose if needed; psychiatric side effects increase greatly at higher dosages.
Appetite Stimulant: 2.5 mg before lunch or dinner, or 2.5 mg at bedtime. Dosage may be increased to 20 mg a day.
Overdosage
Overdose symptoms may occur at usual dosages or at higher dosages if the drug is being abused. The primary symptoms of
overdose are the psychological symptoms listed above (see “Possible Side Effects”). In some cases, overdose may lead to panic reactions or seizure. Contact a hospital or local poison center for more information. If you seek treatment, ALWAYS bring the prescription bottle or container.

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.
• Potassium-sparing diuretics should be used with caution in combination with ACE inhibitors.
Food Interactions

Type of Drug
Antihistamine and antiemetic (an agent that prevents or relieves nausea and vomiting).
Prescribed For
Nausea, vomiting, vertigo, and dizziness associated with motion
sickness.
General Information
Dimenhydrinate, which depresses middle ear function, is a mixture of diphenhydramine—an antihistamine believed to be the active ingredient—and another ingredient. Meclizine is an antihistamine. It takes a little longer to start working than dimenhydrinate, but its effects last much longer. Meclizine does a better job of preventing motion sickness than treating its symptoms. It takes 30 minutes to 1 hour to work and lasts for 12-24 hours.
Cautions and Warnings
Do not take dimenhydrinate if you are allergic or sensitive to any of its ingredients. Newborn babies should not be given this drug.
People with a prostate condition, stomach ulcer, intestinal obstruction, bladder problems, difficulty urinating, glaucoma, asthma, or abnormal heart rhythms should use dimenhydrinate only while under a doctor’s care.
Because it controls nausea and vomiting, dimenhydrinate may hide the symptoms of appendicitis or overdoses of other drugs.
Possible Side Effects
✓ Most common: drowsiness.
♦ Less common: confusion; nervousness; excitation; restlessness; headache; sleeplessness, especially in children; tingling; heavy or weak hands; fainting; dizziness; tiredness; rapid heartbeat; low blood pressure; heart palpitations; blurred or double vision; difficult or painful urination; increased sensitivity to the sun; appetite loss; nausea; vomiting; diarrhea; upset stomach; constipation; nightmares; rash; drug reaction (symptoms include rash, itching, hives, and breathing difficulties); ringing or buzzing in the ears-, dry mouth, nose, or throat; stuffy nose-, wheezing: and increased chest phlegm OT chest tightness.
Drug Interactions
• This drug should not be taken with a monoamine oxidase inhibitor antidepressant.
• Taking dimenhydrinate with an alcoholic beverage, other antihistamine, sedative, or other central-nervous-system (CNS)
depressant may cause excessive dizziness, drowsiness, or other signs of depression.
• Side effects of anticholinergics may be increased when taken with dimenhydrinate.
• Combining dimenhydrinate and certain antibiotics that cause dizziness or other ear-related side effects may mask early signs of these side effects, especially in infants and children.
Food Interactions
Take dimenhydrinate with food or milk if it upsets your stomach.
Usual Dose
Dimenhydrinate
Adult and Child (age 13 and over): 50-100 mg-1 or 2 tablets or 4-8 tsp.-30 minutes prior to travel; then every 4-6 hours; do not take more than 400 mg a day.

Child: not recommended.
Overdosage
Symptoms of overdose include drowsiness, clumsiness, unsteadiness, feeling faint, facial flushing, and dry mouth, nose, or throat. Convulsions, coma, and breathing difficulties may also develop. Overdose victims should be taken to a hospital emergency room for treatment. ALWAYS bring the prescription bottle or container.
Special Information
N1 Maximum effectiveness against motion sickness, take dimenhydrinate 1-2 hours before traveling; it may still be effective if taken 30 minutes before traveling.
This drug may cause drowsiness: Be extremely cautious when driving, operating hazardous machinery, or doing anything that requires concentration.
Dimenhydrinate may cause dry mouth, nose, or throat. Sugarless candy, gum, or ice chips can usually relieve these symptoms. Constant dry mouth may increase the likelihood of developing tooth decay or gum disease. Pay special attention to oral hygiene while you are taking dimenhydrinate, and contact your doctor if dry mouth lasts more than 2 weeks.
If you forget to take a dose of dimenhydrinate, take it as soon as you remember. If it is almost time for your next dose, skip the one you forgot and continue with your regular schedule. Do not take a double dose.
Special Populations
Pregnancy/Breast-feeding: Animal studies suggest that meclizine may cause birth defects. Do not take any antihistamine without your doctor’s knowledge if you are or might be pregnant —especially during the last 3 months of pregnancy, because newborns may have severe reactions to antihistamines.
Small amounts of dimenhydrinate may pass into breast milk. Dimenhydrinate may also slow milk production. Nursing mothers who must take dimenhydrinate should use infant formula.
Seniors: Seniors are more sensitive to antihistamine side effects and should take the lowest effective dose.

Generic Name
Disopyramide (die-soe-PIE-rah-mide) 92
Brand Names Norpace
Type of Drug Antiarrhythmic.
Prescribed For Abnormal heart rhythms.
General Information
Disopyramide phosphate slows the rate at which nerve impulses are carried through heart muscle, reducing the response of heart muscle to those impulses. It acts on the heart similarly to the more widely used antiarrhythmic medications procainamide hydrochloride and quinidine sulfate. Disopyramide is often prescribed for people who do not respond to other antiarrhythmic drugs.
Cautions and Warnings
Do not take disopyramide if you are allergic or sensitive to any of its ingredients or if you have heart block, unless you have a cardiac pacemaker.
This drug can worsen heart failure or trigger severely low blood pressure. It should be used in combination with another antiarrhythmic agent or beta blocker with caution.
In rare instances, disopyramide has caused a reduction in blood-sugar levels. Therefore, the drug should be used with caution by diabetics, older adults—who are more susceptible to this effect—and people with poor kidney or liver function. Ask your doctor if you should have your blood-sugar levels checked while taking this drug.
Because of its anticholinergic effects, men with a severe prostate condition and people who have glaucoma, myasthenia gravis, or severe difficulty uritx;aA:jng should use disopyramide with caution.
People with liver or kidney disease must take a reduced dose of disopyramide.
Potassium levels affect the action of disopyramide. People with blood potassium levels that are out of the normal range must correct this imbalance before starting disopyramide.
Norpace CR
Possible Side Effects
♦ Most common: dry mouth, urinary difficulty, and constipation.
♦ Common: blurred vision; dry eyes, nose, and throat; frequent urination; nausea; stomach pain or bloating; gas; dizziness; fatigue; headache; and nervousness.
♦ Less common: itching, rashes, muscle weakness, generalized aches and pains, not feeling well, low blood-potassium levels, increases in blood-cholesterol and triglyceride levels, heart failure, and low blood pressure.
♦ 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
• Phenytoin and rifarnpin may increase the rate at which the body removes disopyramide from the blood. Your disopyramide dose may need alteration if this combination is used. Other drugs known to increase drug breakdown by the liver, such as barbiturates and primidone, may also have this effect.
• Other antiarrhythmic drugs, such as procainamide and quinidine, may increase the effect of disopyramide, making dosage reduction necessary. At the same time, disopyramide may reduce the effectiveness of quinidine.
• When disopyramide is combined with a beta-blocking drug, increased disopyramide effects, additive effects, or depression of heart function may result.
• Azole antifungals, clarithromycin, diclofenac, doxycycline, erythromycin, imatinib, isoniazid, nefazodone, nicardipine, propofol, protease inhibitors, telithromycin, and verapamil may increase the amount of disopyramide in your blood, causing abnormal heart rhythms or other cardiac effects.
• Disopyramide may reduce the effectiveness of oral anticoagulant (blood-thinning) drugs. Your doctor should check your anticoagulant dosage to be sure you are getting the right amount.
• Hydantoins may cause a decrease in the effectiveness of disopyramide.• Disopyramide may increase the amount of digoxin in your blood, though the amount of the increase is not likely to af-
fect your heart.
• St. John’s wort may decrease disopyramide levels.
Food Interactions
Disopyramide should be taken on an empty stomach at least 1
hour before or 2 hours after meals. Usual Dose
Adult: 400-800 mg a day (divided into 2 or 4 doses for the immediate-release form). In severe cases, 400 mg every 6 hours may be required. This level of dosage should be monitored in the hospital. The sustained-release preparation is taken every 12 hours. People with reduced kidney function should receive a lower dosage, depending on the degree of kidney function present. People with liver failure should take 400 mg a day.
Child (age 13-18): 2.5-7 mg a day per lb. of body weight. Child (age 5-12): 4.5-7 mg a day per lb. of body weight. Child (age 1-4): 4.5-9 mg a day per lb. of body weight.
Child (under age 1): 4.5-13.5 mg a day per lb. of body weight.
Overdosage
Overdose symptoms are breathing difficulties, abnormal heart rhythms, and unconsciousness. In severe cases, overdosage can lead to death. Overdose victims should be made to vomit with ipecac syrup—available at any pharmacy—to remove any remaining drug from the stomach. Call your doctor or poison control center before doing this. If you must go to a hospital emergency room, ALWAYS bring the prescription bottle or container. Prompt and vigorous treatment can mean the difference between life and death in severe overdosage.
Special Information
Disopyramide may cause symptoms of low blood sugar: anxiety, chills, cold sweats, drowsiness, excessive hunger, nausea, nervousness, rapid pulse, shakiness, uaus~M% weakness, tiredness, or cool, pale skim If kNSN)appens to you, eat some chocolate, candy, U rilher high-sugar food, and call your doctor at once.
Disopyramide can cause dry mouth, urinary difficulty, constipation, or blurred vision. Call your doctor if these symptoms become severe or intolerable, but do not stop taking the medication without your doctor’s approval.
If disopyramide is required for a child and capsules are not appropriate, your pharmacist can make a liquid product. Do not do this at home: This medication requires special preparation. The liquid should be refrigerated and protected from light and should be thrown away after 30 days.
Do not crush, chew, or open sustained-release capsules.
If you forget to take a dose of disopyramide, take it as soon as possible. However, if it is within 4 hours of your next dose, skip the dose you forgot and go back to your regular schedule. Do not take a double dose.
Special Populations
PregnancylBreast-feeding: Do not take this drug if you are pregnant or planning to become pregnant while using it, because it will pass into the fetus and may affect its development. When disopyramide is considered crucial by your doctor, its potential benefits must carefully be weighed against its risks.
Disopyramide passes into breast milk. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors, especially those with liver or kidney disease, are more sensitive to the effects of this drug.
Generic Name
Dofetilide (DOH-fet-a-lyed)
Brand Name Tikosyn
Type of Drug Antiarrhythmic.
Prescribed For
Specific abnormal heart rhythms.
General Information
Dofetilide is used to establish and maintain normal sinus rhythm in the heart. Dofetilide is available only to hospitals and doctors who receive specific training and education on how to use this drug because of the risks associated with using it.
Cautions and Warnings
Do not take dofetilide if you are allergic or sensitive to any of its ingredients.
Dofetilide is reserved for people whose abnormal heart rhythms have not responded to other drugs. People taking dofetilide must be in a hospital or other facility for at least 3 days where appropriate blood tests can be performed to monitor kidney and heart function.
This drug is cleared through the kidneys. Poor kidney function increases the amount of dofetilide in the body. Liver disease has no effect on dofetilide blood levels.
Dofetilide, like other antiarrhythmic drugs, can cause severe and sometimes fatal abnormal rhythms of its own.
Do not take dofetilide without first talking to your doctor if you have a low blood level of potassium or magnesium.
Women may be at a greater risk for some arrhythmias caused by dofetilide.
Possible Side Effects
Serious heart arrhythmias can develop in up to 31b% of patients taking up to 1000 mcg a day of dofetilide. People taking daily doses above 1000 mcg a day are at up to 5 times greater risk for arrhythmias.
• Most common: headache, chest pain, and respiratory infection.
♦ Common: difficulty breathing, nausea, and dizziness.
♦ Less common: flu; sleeplessness; accidental injury; back pain; diarrhea; abdominal pain; angina; anxiety: joint pain; weakness; atrial and ventricular arrhythmia; high blood pressure; pain; heart palpitations; swollen legs, ankles, or arms; sweating; and urinary infections.
♦ Rare: some arrhythmias, heart attack, hives, slow heartbeat, stroke, facial or other paralysis, tingling in the hands or feet, cough, liver damage, migraine, fainting, and sudden death. Contact your doctor if you experience any side effect not listed above.
‘D?Ug Interactions
Dofetilide should not be given with drugs that are known to interact with it. Dofetilide must be stopped at least 2 days before any potentially interacting drug is taken.
• Do not mix dofetilide with any product containing verapamil, a calcium channel blocker, or trimethoprim, used for urinary infections. These combinations can substantially raise the amount of dofetilide in the blood.
• Some drugs may increase the amount of dofetilide in the blood by inhibiting enzymes that break it down in the liver. They include delavirdine, indinavir, btonavir, saquinavir, amiodarone, cimetidine, ciprofloxacin, clarithromycin, cannabis, diltiazem, erythromycin, fluconazole, fluvoxamine, itraconazole, ketoconazole, mifepristone, nefazodone, norfloxacin, mibefradil, selective serotonin reuptake inhibitors (SSRIS), troleandomycin, and zatirlukast.
• Some drugs may reduce the amount of dofetilide in the blood by stimulating enzymes that break it down in the liver, including efavirenz, nevirapine, carbamazepine, corticosteroids, modafanil, phenobarbital and other barbiturates, phenytoin, pioglitazone, and rifampin. Amiloride, metformin, megestrol, and triamterene can interfere with the elimination of dofetilide via the kidney, raising blood levels of the drug.
• Other drugs that can increase the effects of dofetilide are Other antiarrhythmic drugs, bepridil, phenothiazines, and tricyclic antidepressants.
• Mixing dofetilide with digoxin may lead to a ventricular arrhythmia called torsade de pointes. Thiazides, furosemide, and other potassium-depleting diuretics can also increase the risk of this arrhythmia.
Food Interactions
Grapefruit juice may increase dofetilide blood levels.
Usual Dose
Adult: 125-500 mcg twice a day.
Child (under 18 years): not recommended.
Overdosage
Dofetilide overdose is likely to cause significant heart rhythm problems. Overdose victims must be treated symptomatically by their cardiologist.
Special Information
Read all information supplied to you before you begin taking this medication and read it again if anything in your treatment program changes.
Tell your doctor about any changes in your prescription or nonprescription drug use or in your use of vitamins, minerals, and other dietary supplement products.
Be sure that any other doctor or hospital that treats you and might prescribe another drug knows you are taking dofetilide.
Call your doctor at once if you develop any signs of altered electrolyte balance including excessive or prolonged diarrhea, sweating, vomiting, appetite changes, or excessive thirst.
If you forget to take a dose, 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: Dofetilide causes birth defects in animal studies. Pregnant women should take this drug only after discussing with their doctors its potential benefits and risks.
It is unknown whether dofetilide passes into breast milk. Nursing mothers who take it should consider using infant formula.

Dicyclomine - Digoxin - Diltiazem
August 12, 2009 | Leave a Comment
Generic Name
Dicyclomine (dih-SYE-kloe-meen) 10j
Brand Names
Bemote Dilomine
Bentyl Di-Spaz
Bycloft),e Or-Tyl Dibent
Type of Drug
Antispasmodic and anticholinergic.
Prescribed For
Irritable bowel, spastic colon, and similar digestive problems; also prescribed for colic in children over age 6 months.
General Information
Dicyclomine hydrochloride has been used for many years to calm “nervous stomach.” It and other anticholinergics work by blocking the effects of the neurohormone acetylcholine in the gastrointestinal (GI) tract. This reduces the mobility of the GI tract and slows the production of enzymes and other secretions.
Cautions and Warnings
Do not take dicyclomine if you are allergic or sensitive to any of its ingredients.
Dicyclomine should not be used by those with obstructive disease of the GI or urinary tract, severe ulcerative colitis, reflux esophagitis, acute bleeding with unstable heart function, myasthenia gravis, or glaucoma.
Dicyclomine should not be used in infants less than age 6 months or by breastfeeding mothers.
This drug should be used with caution if you have heart disease, Down’s syndrome, spastic paralysis, reduced mobility of the stomach and lower esophagus, fever, urinary difficulties, enlarged prostate, hiatal hernia, intestinal paralysis, kidney or liver disease, rapid heartbeat, hyperthyroidism (overactive thyroid gland), high blood pressure, or ulcerative colitis.
Dicyclomine reduces your ability to sweat and may lead to heat exhaustion and heatstroke, which can be life-threatening. Avoid extended heavy exercise and limit your exposure to high temperatures.
Anticholinergenic psychosis has been reported by those taking anticholinergenics, but it usually resolves within 24 hours after discontinuation of the drug.
Possible Side EfferkS
♦ Common: dry mouth, dizziness, blurred vision, nausea, and lightheadedness.
V Less common: drowsiness, weakness, nervousness, constipation, and decreased sweating.
Possible Side Effects (continued)
♦ Rare: drug allergy (symptoms include rash, itching, lives,
and breathing difficulties), confusion, eye pain, dizziness
when rising quickly from a sitting or lying position, a bloated
feeling, difficult or painful urination, headache, memory
loss, and vomiting. Contact your doctor if you experience
any side effect not listed above.
Drug Interactions
• Antacids containing calcium or magnesium, citrates, sodium bicarbonate, and carbonic anhydrase inhibitor drugs may increase dicyclomine’s therapeutic effect and side effects.
• Combining dicyclomine with other anticholinergic drugs including atropine, belladonna, clidinium, glycopyrrolate, hyoscyamine, isopropamide, propantheline, and scopolamine may intensify side effects.
• Dicyclomine may reduce stomach acidity and blood levels of oral ketoconazole (an antifungal).
• Dicyclomine may decrease the therapeutic effects of anti-glaucoma medications. Taking dicyclomine with corticosteroids used to treat glaucoma may be hazardous.
• Dicyclomine may counteract the effect of metoclopramide in reducing nausea and vomiting.
• Taking dicyclomine with a narcotic pain reliever may cause severe constipation.
• Taking this or any drug that slows the movement of stomach and intestinal muscles with a potassium chloride supplement –especially one in wax-matrix tablet form—may lead to excessive irritation of the stomach.
• Combining dicyclomine with amantadine, certain drugs to control heart rhythm, antihistamines, nitrates or nitrites, may increase dicyclomine side effects.
• Dicyclomine may increase the effects of atenolol and digoxin.
• Pftn0hiazine drugs, monoamine oxidase inhibitor antidepressants, benzodiazepines, and tricyclic antidepressants may increase side effects of dicyclomine. The effectiveness of phenothiazines to control psychotic symptoms may be decreased.
Food Interactions
Take dicyclomine on an empty stomach, a half hour before or 2 hours after a meal.
Usual Dose
Adult: 80-160 mg a day in 4 divided doses. Seniors should receive the lowest possible dosage and increase only as needed. Child (age 2 and over): 5-10 mg 3-4 times a day.
Child (age 6 months-2 years): 5-10 mg of syrup 3-4 times a day. Child (under 6 months): not recommended.
Overdosage
Symptoms include blurred vision; clumsiness; confusion; breathing difficulties; dizziness; drowsiness; dry mouth, nose, or throat; rapid heartbeat; fever; hallucinations; weakness; slurred speech; excitement, restlessness, or irritability; warmth; and dry or flushed skin. Take the victim to a hospital emergency room at once. ALWAYS bring the prescription bottle or container.
Special Information
Children taking dicyclomine may be more likely to develop high body temperature in hot weather and other side effects and should be carefully watched for side effects. Dicyclomine should not be given to infants or children unless the doctor decides that its use is absolutely necessary.
Call your doctor if you develop diarrhea, rash, flushing, eye pain, dry mouth, urinary difficulties, constipation, increased sensitivity to light, or any bothersome or persistent side effect.
Brush and floss your teeth regularly while taking this drug. Because dicyclomine may cause dry mouth, you may be more likely to develop cavities or other dental problems. Ice or hard candy may relieve dry mouth.
Constipation may be treated by using a laxative.
Dicyclomine may make you drowsy or tired and cause blurred vision. Be careful when driving or doing any task that requires concentration.
If you forget 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: A few cases of human malformation were linked to dicyclomine, but studies have shown that the drug has no effect on the fetus. When this drug is considered crucial by your doctor, its potential benefits must be carefully weighed against its risks.
Dicyclomine can reduce the amount of milk produced. Infants given dicyclomine may faint, go limp, and develop breathing problems and seizures. Nursing mothers who must take this drug should use infant formula.
Seniors: Seniors may be more susceptible to side effects, especially memory loss, changes in mental state, and glaucoma. Seniors may obtain maximum benefit with smaller dosages.
Generic Name
Digoxin (dih-JOX-in) A
Brand Names Digitek
Lanoxicaps
Lanoxin
Type of Drug Cardiac glycoside.
Prescribed For
Congestive heart failure (CHF) and other heart conditions involving a very rapid heartbeat.
General Information
Digoxin works directly on heart muscle. It improves the heart’s pumping ability or helps to control its beating rhythm. People with heart failure often develop swelling of the lower legs, feet, and ankles; digoxin improves these symptoms by improving blood cir-
Digoxin is generally used as part of the lifelong treatment of CHF.
Cautions and Warnings
Do not use digoxin if you are allergic or sensitive to it. Digoxin allergies are rare.
Digoxin should not be used in people with ventricular fibril-
lation.
Digoxin should be used with caution in people with sick sinus
syndrome or incomplete AV block, as it may cause a worsening of these conditions.
Digoxin has been used to treat obesity. The risk of fatal heart rhythms associated with such treatment makes it extremely dangerous as weight-loss medication. Many heart disease symptoms may be associated with digoxin. Report any unusual side effects to your doctor at once.
Kidney disease may increase blood levels of digoxin. Your dosage may need adjustment.
Long-term use of digoxin may cause the body to lose potassium, especially since it is generally used in combination with diuretics (agents that increase urination). For this reason, be sure to eat a balanced diet and high-potassium foods—bananas, citrus fruits, melons, and tomatoes.
Digoxin should be used with caution in people with electrolyte disorders.
Digoxin requirements vary with thyroid status. If you are taking digoxin and your thyroid status changes, your doctor will have to alter your digoxin dosage.
Possible Side Effects
Adult and Senior
♦ Common: dizziness, headache, nausea, and diarrhea.
✓ Less common: appetite loss, vomiting, weakness, apathy, drowsiness, blurred or yellow-tinted vision, seeing halos around bright lights, depression, psychoses, confusion or disorientation, restlessness, hallucinations, delirium, seizure, nerve pain, abnormal heart rhythms, and slow pulse.
✓ Rare: Enlargement of the breasts has been reported after long-term use of digoxin. Contact your doctor if you experience any side effect not listed above.
Child
T Children are more likely to develop abnormal heart rhythms before they see yellow or green halos or spots and before they develop nausea, vomiting, diarrhea, or stomach pain. Any abnormal heart rhythms that develop while a child is taking digoxin should be assumed to be a side effect.
Drug Interactions
• Drugs that may increase the effect of digoxin are alprazolam, amiloride aminoglycoside antibiotics, amiodarone, anticholinergic drugs, benzodiazepines, captopril, clarithromycin, diltiazem, diphenoxylate, dipyridamole, erythromycin, esmolol, felodipine, flecainide, hydroxychloroquine, ibuprofen, indomethacin, itraconazole, nifedipine, nitrendipine, omeprazole, propafenone, propantheline, quinidine, quinine, spironolactone, tetracycline, tolbutamide, triamterene, and verapamil.
• Drugs that may decrease blood levels of digoxin include aminoglutethimide, aminoglycosides, aminosalicylic acid, antacids, anti-cancer combinations, antidiabetes medication, antihistamines, barbiturates, cholestyramine, colestipol, cyclosporine, kaolin-pectin mixtures, metoclopramide, oral kanamycin, oral neomycin, oral sulfonylureas, phenylbutazone, phenytoin and related anti-seizure drugs, rifampin, St. John’s wort, sucralfate, and sulfasalazine.
• Disopyramide may alter the effects of digoxin, although the exact interaction is not well understood.
• Thiazide and loop diuretics, furosemide, ethacrynic acid, and bumetanide increase digoxin’s effect and increase the risk of side effects.
• Spironolactone may increase or decrease the side effects of digoxin; amiloride may reduce the effect of digoxin on the force of heart contraction.
• The effects of digoxin on the heart may be additive to those of ephedrine, epinephrine and other stimulants, beta blockers, calcium salts, procainamide, and rauwolfia drugs.
• Digoxin dosage must be adjusted when it is combined with a thyroid drug.
Food Interactions
These drugs may generally be taken without regard to meals. Taking your medication after a high-fiber meal reduces the amourxtcil drug absorbed into your blood.
Usual OQSS
Adult and Child (age 10 and over): starting dosage—known as the digitalizing or loading dose—is about 4-7 mcg per lb. of body weight. Digitalization may also be accomplished with a lower dosage over 7 days. Maintenance dosage 0.125-0.5 mg; it must be corrected for kidney function. For seniors, a lower dosage is required.
Child (under age 1o): starting dosage-5-30 mcg per lb. of body weight. Maintenance dosage-20-35% of the starting dosage. Careful measurement of your child’s digoxin dosage is crucial to safe and effective treatment.
Overdosage
Adult: Symptoms include appetite loss, nausea, vomiting, diarrhea, headache, weakness, apathy, blurred vision, yellow or green spots or halos before the eyes, yellowing of the skin or whites of the eyes, and changes in heartbeat.
Senior: Vomiting, diarrhea, and eye trouble are frequently seen. Child: An early sign is a change in heart rhythms.
Call your doctor immediately if any of these symptoms appear. Take the victim to a hospital emergency room. ALWAYS bring the prescription bottle or container.
Special Information
Take each day’s dose at the same time of day.
Do not stop taking digoxin without your doctor’s knowledge.
Lanoxicaps are better absorbed than tablet forms of digoxin. For this reason, each dose of Lanoxicaps is slightly lower than the corresponding digoxin tablet.
Avoid over-the-counter diet and cold medications containing stimulants.
Call your doctor at once if you develop side effects.
There may by some variation between digoxin tablets from different manufacturers. Do not change drug brands without telling your doctor.
Check your pulse every day—your doctor will teach you how—and call your doctor if it drops below 60 beats per minute.
If you forget a dose and remember at least 12 hours before your next dose, take it right away. If you do not remember until it is less than 12 hours before your next dose, skip the one you forgot and continue with your regular schedule. Do “lot take a double dose. Call your doctor if you M1 a dose for 2 or more days.
Special Populations
Pregnancy/Breast-feeding: Digoxin crosses into the fetal circulation. While digoxin is sometimes used during pregnancy to treat fetal heart disease, women who are or might be pregnant should not take digoxin without their doctor’s approval. When your doc-tor considers this drug crucial, its potential benefits must be care-
fully weighed against its risks.
Small amounts of digoxin pass into breast milk. Nursing mothers who take digoxin should use infant formula.
Seniors: Seniors are more sensitive to digoxin’s effects, especially appetite loss. Seniors with impaired renal function may need lower
dosages.
Generic Name
Diltiazem (dil-TYE-uh-zem) 92
Brand Names
Cardizem Dilt-CD
Cardizem CD Diltia XT
Cardizem LA Diltzac
Cartia XT Taztia XT
Dilator XR Tiazac
Type of Drug
Calcium channel blocker.
Prescribed For
Angina pectoris, chronic stable angina, Raynaud’s disease, prevention of second heart attacks, tardive dyskinesia (severe side effects associated with antipsychotic and other drugs), and hypertension (high blood pressure).
General Information
Diltiazem hydrochloride is one of many calcium channel blockers available in the U.S. These drugs block the passage of calcium, an essential factor in muscle contraction, into the heart and smooth muscles. Such blockage of calcium interferes with the contraction of these muscles, which in turn dilates (widens) the veins and ves sels that supply blood to them. This ditatk”q effect reduces blood pressure, the amount 0 Oxygen used by the heart muscle, and the ~1A 0 blood vessel spasm. Diltiazem is therefore useful in treating not only hypertension but also angina pectoris, a condition related to poor oxygen supply to the heart muscle and characterized by brief attacks of chest pain.
Diltiazem affects the movement of calcium only into muscle cells; it has no effect on calcium in the blood.
Cautions and Warnings
Do not take d,1taz&m1f you are allergic or sensitive to any of its
ingredients.
Diltiazem can slow your heart and interfere with normal electrical conduction. For people with a condition called sick sinus syndrome, this can result in temporary heart stoppage.
Diltiazem should not be taken if you are having a heart attack or if you have lung congestion. Diltiazem should be taken with caution by people with heart failure because it can worsen that condition.
Low blood pressure may occur, especially in people also taking a beta blocker.
Studies have shown that people taking calcium channel blockers—usually those taken several times a day, not those taken once daily—have a greater chance of having a heart attack than people taking beta blockers or another medicine for the same purposes. Discuss this with your doctor to be sure you are receiving the best possible treatment.
Diltiazem can cause severe liver damage and should be taken with caution if you have had hepatitis or any other liver condition.
Caution should also be exercised if you have a history of kidney problems, although no clear tendency toward causing kidney damage is seen with this drug.
Possible Side Effects
♦ Common: dizziness, lightheadedness, weakness, head-
ache, and fluid accumulation in the hands, legs, or feet.
✓ Less common: low blood pressure, fainting, increase or decrease in heart rate, abnormal heart rhythm, heart failure, nervousness, fatigue, nausea, rash, tingling in the hands or feet, hallucinations, temporary memory loss, difficulty sleeping, diarrhea, vomiting, constipation, upset stomach, itching, unusual sensitivity to sunlight, paxnlu) or stiff joints, liver inflammation, and increased urination, especially at night.
Drug Interactions
• Diltiazem taken with a beta-blocking drug for hypertension is usually well tolerated, but may lead to heart failure in people with already weakened hearts.
• Calcium channel blockers, including diltiazem, may add to
the effects of digoxin. This effect is not observed with any
consistency, however, and only affects people with a large
amount of digoxin already in their systems.
• Cimetidine and ranitidine increase the amount of diltiazem in the bloodstream and may account for a slight increase in the drug’s effect.
• Diltiazem may increase blood levels of cyclosporine, carbamazepine, encainide, and theophylline, and thus increase the chance of side effects from these drugs.
• Diltiazem may cause a decrease in blood lithium levels, possibly undermining lithium’s antimanic effect.
• Calcium channel blockers may cause bleeding when taken alone or combined with aspirin.
Food Interactions
Diltiazem is best taken on an empty stomach, at least 1 hour before or 2 hours after meals.
