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.
Usual Dose
Immediate-Release Products 30-60 mg 4 times a day.
Sustained-Release/Extended-Release Products Cardizem CD: 120-480 mg once a day. Cardizem LA: 120-540 mg once a day. Cartia XT: 120-300 mg once a day. Dilacor XR: 180-480 mg once a day. Dilt-CD: 120-360 mg once a day. Diltia XT: 180-480 mg once a day. Diltzac: 120-360 mg once a day. Taztia XT: 120-150 mg once a day. Tiazac: 120-360 mg once a day.
Overdosage
Symptoms of diltiazem overdose are very low blood pressure and reduced heart rate. Overdose victims must be made to vomit with 1J)8C2c syrup—available at any pharmacy—within 30 minutes of taking the overdose. Do not induce vomiting if the victim has fainted or is convulsing. If overdose symptoms have developed or more than 30 minutes have passed, vomiting is of little value. Take the victim to a hospital emergency room immediately. ALWAYS bring the prescription bottle or container.
Special information
Call your doctor if you develop any of the following symptoms! swelling of the hands, legs, or feet-, severe dizziness; constipation or nausea; or very low blood pressure.
Do not open, chew, or crush sustained-release capsules of
diltiazem.
If you take your diltiazem 3 or 4 times a day and forget a dose, take it as soon as you remember. Space the remaining doses throughout the rest of the day. If you take diltiazem 1 or 2 times a day and forget to take 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. Never take a double dose.
Special Populations
Pregnancy/Breast-feeding: In animal studies. high doses of diltiazem interfered with the development of the fetus. Diltiazem should not be taken by women who are or might be pregnant. When your doctor considers this drug crucial, its potential benefits must be carefully weighed against its risks.
Because diltiazem passes into breast milk, nursing mothers taking this drug should use infant formula.
Seniors: Seniors may be more sensitive to the effects of this drug because it takes longer to pass out of their bodies.

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.

Aldosterone Blockers
July 16, 2009 | Leave a Comment
Type of Drug
Aldosterone Blockers (al-DOH-stir-own)
Brand Names
Generic Ingredient: Eplerenone Inspra
Generic Ingredient. Spironolactone Aldactone
Combination Product
Generic Ingredients: Hydrochlorothiazide + Spironolactone Aldactazide
Prescribed For
High blood pressure, cirrhosis, and congestive heart failure (CHF); also used for people with low blood potassium who require a diuretic.
General Information
Aldosterone blockers limit the access of aldosterone—a hormone that helps to regulate several different body functions—from its receptor. Too much aldosterone results in high sodium levels, which can lead to water retention and potassium loss; it can also affect the size, shape, and function of the heart. Aldosterone blockers are generally combined with other medicines in the management of disease. These drugs are useful in removing excess body fluids in conditions associated with high aldosterone levels.
One in every ten people with high blood pressure has excess aldosterone in their systems. In people with congestive heart failure (CHF), aldosterone levels can be 20 times higher than normal, which can worsen their condition, making the use of aldosterone blockers an important part of their treatment. Aldosterone block-ers also help the heart return to normal size, shape, and function in people with heart failure. Eplerenone is broken down in the liver, primarily by an enzyme system known as CYP3A4.
Cautions and Warnings
Do not take aldosterone blockers if you are allergic or sensitive to any of their ingredients.
Do not use aldosterone blockers if you have kidney failure or high blood potassium.
People with liver disease should be cautious about using a!- dosterone blockers.
People taking an aldosterone blocker should have their potassium levels checked periodically.
People with diabetes who have albumin in their urine should not take aldosterone blockers.
Possible Side Effects
Eplerenone
✓ Less common: dizziness, diarrhea, fatigue, flu-like symptoms, coughing, abdominal pain, elevation of blood cholesterol and/or triglyceride levels, elevation of blood potassium levels, and albumin in the urine.
✓ Rare: enlargement of the breasts in males, irregular menstrual cycles in women, and painful breasts. Contact your doctor if you experience any side effect not listed above.
Spironolactone
✓ Less common: drowsiness, lethargy, headache, gastrointestinal upset, cramps and diarrhea, rash, mental confusion, fever, feeling unwell, enlargement of the breasts in males, impotence, and irregular menstrual cycles or deepening of the voice in women.
Drug Interactions
• Do not combine eplerenone with itraconazole or ketoconazole. These drugs can cause the amount of eplerenone in the blood to increase by up to 500% and may cause fatal increases in blood potassium.
• Mixing eplerenone with erythromycin, fluconazole, saquinavir, or verapamil increases the amount of eplerenone in the blood. People taking this combination must watch for signs of high blood potassium (see “Special Information”) and have their blood potassium levels checked regularly.
• Combining a potassium supplement and an aldosterone blocker can lead to dangerously high blood levels of potassium. Do not use a salt-substitute or take any extra potassium unless prescribed by your doctor.
• Combining an aldosterone blocker with an ACE inhibitor or an angiotensin H receptor blocker (ARB) may significantly raise blood potassium. Be sure your doctor monitors your potassium levels if you combine these drugs.
• Spironolactone may interfere with anticoagulant (blood-thinning) drugs and mitotane (an anticancer drug).
• Aspirin can interfere with the diuretic effect of spironolactone but does not alter its effect on high blood pressure or CHF.
• Combining spironolactone with alcohol, barbiturates, or narcotics can lead to dizziness or fainting when rising suddenly from a sitting or lying position.
• Combining spironolactone and a corticosteroid can lead to very low blood potassium.
• Spironolactone may alter your response to drugs used during general anesthesia.
• Lithium generally should not be combined with any diuretic.
• Combining nonsteroidal anti-inflammatory drugs (NSAIDs) with aldosterone blockers can lead to severe elevations of blood potassium and reduce the blood-pressure-lowering effect of the diuretic.
• Spironolactone may raise digoxin blood levels and increase the risk of severe digoxin side effects. Your doctor may have to adjust your digoxin dosage.
• St. John’s wort (a CYP3A4 inducer) may decrease eplerenone levels by about 30%.
Food Interactions
Food appears to increase the amount of spironolactone absorbed into the blood. Take this drug with food at the same time every day. Eplerenone may be taken without regard to food or meals. Taking this drug with grapefruit juice increases the amount of drug absorbed into your body.
Usual Dose
Eplerenone
Adult 50-100 mg a day. Child: not recommended.
Spironolactone
Adult: Starting dosage is 50-100 mg a day in divided doses for high blood pressure; 25-200 mg a day in divided doses for high fluid levels related to other diseases; and 25-100 mg a day for low potassium levels related to diuretic use.
Child: 1-2 mg per lb. of body weight a day.
Spironolactone + Hydrochlorothiazide Adult: 1-4 tablets daily.
Overdosage
Eplerencne overdose may lead to low blood pressure and high blood potassium. Spironolactone overdose may lead to drowsiness. confusion, rash, nausea, vomiting, dizziness, and diarrhea. Rarely. coma may occur in people with severe liver disease. High blood potassium may also occur, especially in people with kidney zsease. Call your local poison control center or a hospital emercency room for more information. If you seek treatment, ALWAYS oring the prescription bottle or container.
Special Information
<e a c!osterone blockers exactly as they are prescribed.
High blood levels of potassium associated with aldosterone blockers may cause weakness, lethargy, drowsiness, muscle pain or cramps, and muscular fatigue. Use caution while doing anything that requires intense concentration, like driving or operating machinery.
Do not use a salt substitute or take anything else that is a source of extra potassium, including many multivitamin or supplement products.
People with high blood pressure should not self-medicate with over-the-counter cough, cold, or allergy remedies containing stimulants. These drugs can raise blood pressure effectiveness and have an adverse effect on the heart.
!f 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.
Special Populations
Pregnancy/Breast-feeding: Animal studies with eplerenone showed no effects on a developing fetus. Spironolactone crosses into the fetal circulation. When your doctor considers either of these drugs crucial, their potential benefits must be carefully weighed against their risks.

Brand Names
AccuNeb Proventil HFA
ProAir HFA Ventolin HFA
Proventil* Vospire ER
Combination Products
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.

Acyclovir
July 16, 2009 | Leave a Comment
Generic Name
Acyclovir (ae-SYE-kloe-vir) 4i
Brand Name Zovirax
Type of Drug Antiviral.
Prescribed For
Initial treatment and maintenance of genital herpes outbreaks; treatment of herpes zoster (shingles); and treatment of varicella (chickenpox).
General Information
Acyclovir is the only oral drug that reduces growth rates of the herpes virus and the related viruses, Epstein-Barr, varicella, and cytomegalovirus (CMV); both oral acyclovir and oral ganciclovir work against CMV Intravenous drugs, including acyclovir injection, may also be used for these viral infections; however, intravenous antiviral drugs are usually reserved for patients with HIV, cancer, or otherwise compromised immune systems.
Acyclovir is selectively absorbed into cells that are infected with the herpes simplex virus, where it is converted into its active form. Acyclovir works by interfering with the reproduction of viral DNA, slowing the growth of existing viruses. It has little effect on recurrent infections. To treat both local and systemic (whole-body) symptoms acyclovir must be given by intravenous injection or taken by mouth. Local symptoms may be treated with the ointment alone. Oral acyclovir may be taken every day to reduce the number and severity of herpes attacks in people who suffer 10 or more attacks a year; it may also be used to treat intermittent attacks as they occur, but treatment must be started as soon as possible to have the greatest effect.
Cautions and Warnings
Do not use acyclovir if you are allergic or sensitive to any of its ingredients. Do not use acyclovir ointment if you have had an allergic reaction to it or to the major component of the ointment base, polyethylene glycol. Do not apply acyclovir ointment inside the vagina because the polyethylene glycol base may cause irritation and swelling of sensitive vaginal tissue. Acyclovir ointment is not intended for use in the eye and should not be used to treat a herpes infection of the eye.
Renal failure has occurred in patients using oral acyclovir, in some cases resulting in death. People with kidney impairment should have dosages adjusted accordingly.
Maintain adequate hydration while taking oral acyclovir. Animal testing indicates that acyclovir may affect fertility in men. These effects may be reversible.
Possible Side Effects
Capsules, Suspension, and Tablets
✓ Most common: feeling unwell, headache, diarrhea, nausea, and vomiting.
✓ Less common: appetite loss, stomach gas, constipation, fatigue, rash, leg pains, sore throat, a bad taste in the mouth, sleeplessness, and fever.
♦ Rare: aching joints, weakness, and tingling in the hands or feet. Contact your doctor if you experience any side effect not listed above.
Ointment
✓ Most common: mild burning, irritation, rash, and itching. These effects are more likely to occur when treating an initial herpes attack than a recurrent attack. Women are 4 times more likely to experience burning than men.
Drug Interactions
• Do not apply acyclovir together with any other ointment or topical medication.
• Oral probenecid may decrease elimination of acyclovir from the body, which increases blood levels of oral or injected acyclovir, increasing the risk of side effects.
• Combining acyclovir and zidovudine (an HIV drug—also known as AZT) may lead to severe drowsiness and lethargy.
Food Interactions
Acyclovir may be taken with food if it upsets your stomach.
Usual Dose
Capsules, Suspension, and Tablets
Adult: genital herpes attack-200 mg every 4 hours, 5 times a day for 10 days. Recurrent infections-400 mg 3 times a day or 200 mg 5 times a day for 5 days. Suppressive therapy for chronic herpes-800 mg a day, every day for up to a year. Herpes zoster800 mg 5 times a day for 7-10 days.
Child (age 2 and over): Acyclovir has been given to children in daily doses as high as 36 mg per lb. of body weight without any unusual side effects.
Child (under age 2): not recommended.
If you have kidney disease, your doctor should adjust your dose according to the degree of functional loss.
Ointment: Apply every 3 hours, 6 times a day for 7 days. Apply enough medication to cover all visible skin lesions. About 1/2 in. of ointment should cover about 4 sq. in. of lesions. Your doctor may prescribe a longer course of treatment to prevent the delayed formation of new lesions over the duration of an attack. Begin using ointment at the first sign of an attack.
Overdosage
Overdose of oral acyclovir may lead to kidney damage due to deposits of acyclovir crystals in the kidneys. Other side effects include agitation, seizures, lethargy, and coma. The risk of experiencing toxic side effects from swallowing acyclovir ointment is quite small. In the case of overdose or accidental ingestion, call your poison control center. ALWAYS bring the prescription bottle or container.
Special Information
Use a finger cot or rubber glove when applying acyclovir ointment to protect against inadvertently spreading the virus. Be sure to apply the medication exactly as directed and to completely cover all lesions. Keep affected areas clean and dry. Loose-fitting clothing will reduce possible irritation of a healing lesion. If you skip several doses, or a day or more of treatment, the drug will not exert its maximum effect.
Acyclovir is not a cure for genital herpes. Herpes may be transmitted even if you do not have symptoms of active disease. To avoid giving the condition to a sexual partner, do not have intercourse while visible herpes lesions are present. A condom offers some protection against transmission of the herpes virus, but spermicidal products and diaphragms do not. Acyclovir alone will not prevent herpes transmission.
Initiate therapy at the first sign of symptoms.
Women with genital herpes have an increased risk of cervical cancer. Speak with your doctor about the need for an annual Pap smear.
Call your doctor if acyclovir does not relieve your symptoms, if side effects become severe or intolerable, or if you become pregnant or want to begin breast-feeding. Check with your dentist if you notice swelling or tenderness of the gums.
Avoid exposure to excessive sunlight or sunlamps because of unusual sensitivity caused by oral acyclovir.
Special Populations
Pregnancy/Breast-feeding: Acyclovir crosses into the circulation of the fetus. Animal studies have shown that large doses—up to 125 times the human dose—cause damage to both mother and fetus. While there is no information to indicate that acyclovir affects a human fetus, do not use it during pregnancy unless it is specifically prescribed by your doctor and the possible benefit outweighs the risk.
Acyclovir passes into breast milk in concentrations up to 4 times the concentration in blood, and it has been found in the urine of a nursing infant. Although no side effects have been found in nursing babies, mothers who must take acyclovir should use infant formula.
Seniors: Shingles attacks in people over age 50 tend to be more severe and respond best to acyclovir treatment if the drug is started within 48-72 hours of the appearance of the first rash. Seniors with reduced kidney function should be given a lower dose of oral acyclovir than younger adults.

Type of Drug
Antipyretic and analgesic.
Prescribed For
Relief of pain and fever for people who cannot or do not want to take aspirin or a nonsteroidal anti-inflammatory drug (NSAID). Acetaminophen may be given to children about to receive a
DTP vaccination to reduce the fever and pain that commonly follow the vaccination.
General Information
Acetaminophen is generally used to relieve pain and fever associated with the common cold, flu, viral infections, or other disorders where pain or fever may occur. It is also used to relieve pain in people who are allergic to aspirin, or those who cannot take aspirin because of potential interactions with other drugs such as oral anticoagulants. It can be used to relieve pain from a variety of sources, including arthritis, headache, muscle ache, menstrual cramping, and tooth and periodontic pain, although it does not reduce inflammation.
Cautions and Warnings
Do not take acetaminophen if you are allergic or sensitive to any of its ingredients. Do not take acetaminophen for more than 10 days in a row (5 days for children) unless directed by your doctor. Do not take more than is prescribed or recommended on the package.
Use this drug with extreme caution if you have kidney or liver disease or viral infections of the liver. Large amounts of alcohol increase the liver toxicity of large doses or overdoses of acetaminophen. Avoid alcohol if you regularly take acetaminophen. Some people are more sensitive to this effect than others.
Possible Side Effects
This drug is relatively free from side effects when taken in recommended doses. For this reason it has become extremely popular, especially among those who cannot take aspirin. V Rare: large doses or long-term use may cause liver dam-
age, rash, itching, fever, lowered blood sugar, stimulation,
yellowing of the skin or whites of the eyes, and/or a change
in the composition of your blood. Contact your doctor if
you experience any side effect not listed above.
Drug Interactions
o Large doses of barbiturate drugs, carbamazepine, phenytoin and similar drugs, izoniazid, rifampin, and sulfinpyrazone may increase the chances of liver toxicity if taken with acetaminophen.
• Alcoholic beverages increase the chances for liver toxicity
and possible liver failure associated with acetaminophen.
Food Interactions
None known.
Usual Dose
Adult and Child (age 12 and over): 325-650 mg 4-6 times a day,
or 1000 mg 3-4 times a day. Avoid taking more than 4 g (twelve
325-mg tablets) a day for long periods of time. Child (age 11): 480 mg 4-5 times a day. Child (age 9-10): 400 mg 4-5 times a day. Child (age 6-8): 320 mg 4-5 times a day. Child (age 4-5): 240 mg 4-5 times a day. Child (age 3): 160 mg 4-5 times a day. Child (age 1-2): 120 mg 4-5 times a day.
Child (age 4-11 months): 80 mg 4-5 times a day. Child (under age 4 months): 40 mg 4-5 times a day.
Overdosage
Acetaminophen is a commonly used ingredient in many over-the-counter (OTC) medications. Always check the list of ingredients when using more than one OTC medication to ensure that the combined dosage is within guidelines and to avoid accidental overdose.
Acute acetaminophen overdose may cause nausea, vomiting, sweating, appetite loss, drowsiness, confusion, abdominal tenderness, low blood pressure, abnormal heart rhythms, yellowing of the skin and whites of the eyes, and liver and kidney failure. Liver damage has occurred with 12 extra-strength tablets or 18 regular-strength tablets, but most people need larger doses-20 extra-strength or 30 regular-strength tablets—to damage their livers. Regular use of large doses for long periods-30004000 mg a day for a year—can also cause liver damage, especially if alcohol is involved. In case of overdose, induce vomiting as soon as possible with ipecac syrup—available at any pharmacy —and take the victim to a hospital emergency room. ALWAYS bring the acetaminophen bottle or container.
Special Information
Unless abused, acetaminophen is a beneficial, effective, and relatively nontoxic drug. Follow package directions and call your doctor if acetaminophen does not relieve pain in 10 days for adults or 5 days for children. Call your doctor if fever gets worse or persists longer than 3 days.
Alcoholic beverages will worsen the liver damage that acetaminophen can cause. People who take this drug on a regular basis should limit their alcohol intake.
If you forget to take a dose, take it as soon as you remember. If it is within an hour of 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: Acetaminophen ‘is considered safe during pregnancy when taken in usual doses. Taking continuous high doses of the drug may cause birth defects or interfere with fetal development. Three cases of congenital hip dislocation appear to have been associated with acetaminophen. Check with your doctor before taking this drug if you are or might be pregnant.
Small amounts of acetaminophen may pass into breast milk, but the drug is considered harmless to nursing infants.
Seniors: Seniors may take acetaminophen as directed by a doctor.

Acebutolol
July 16, 2009 | Leave a Comment
Generic Name
Acebutolol (ah-seh-BUTE-uh-lol) 91
Brand Name Sectral
Type of Drug
Beta-adrenergic blocking agent. Prescribed For
High blood pressure and abnormal heart rhythms.
General Information
Acebutolol hydrochloride is one of many beta-adrenergic blocking drugs, or beta blockers. These drugs interfere with the action of adrenaline and other chemicals in the body that affect many body functions. Individual beta blockers have different characteristics that can make them more suitable for certain conditions or people.
Cautions and Warnings
Do not take acebutolol if you are allergic or sensitive to any of its ingredients or to beta blockers.
You should be cautious about taking acebutolol if you have asthma, severe heart failure, a very slow heart rate, or heart block (disruption of the electrical impulses that control heart rate) because the drug may worsen these conditions.
People with angina taking acebutolol for high blood pressure risk aggravating their angina if they suddenly stop taking the drug. These patients should have their acebutolol dosage reduced gradually over 1-2 weeks.
Acebutolol should be used with caution if you have liver or kidney disease because your ability to eliminate this drug from your body may be impaired.
Acebutolol reduces the amount of blood pumped by the heart with each beat. This reduction in blood flow may aggravate the condition of people with poor circulation or circulatory disease.
If you are undergoing major surgery, your doctor may want you to stop taking acebutolol at least 2 days before surgery.
People with a history of severe anaphylactic reaction to alergens may be unresponsive to usual doses of epinephrine while taking beta blockers.
Possible Side Effects
Side effects are relatively uncommon and usually mild; normally they develop early in the course of treatment and are rarely a reason to stop taking acebutolol.
✓ Most common: fatigue.
✓ Common: dizziness and headache.
✓ Less common: chest pain, swelling in the legs or arms, depression, sleeplessness, abnormal dreams, rashes, constipation, diarrhea, upset stomach, stomach gas, nausea, frequent urination, back pain, joint and muscle pain, difficulty breathing, stuffy nose, and vision changes.
♦ Rare: cough, low blood pressure, slow heart beat, anxiety, impotence, changes in response to touch stimulation, itching, vomiting, abdominal pain, painful urination, nighttime urination, liver changes, sore throat, wheezing, eye irritation, pain or dry eye, and lupus erythematosus (extremely rare). Contact your doctor if you experience any side effect not listed above.
Drug Interactions
• Acebutolol may interact with surgical anesthetics to increase the risk of heart problems during surgery. Some anesthesiologists recommend gradually stopping the drug by 2 days before surgery.
• Acebutolol may interfere with the normal signs of low blood sugar and with the action of oral antidiabetes drugs.
• Acebutolol increases the blood-pressure-lowering effects of other blood-pressure-reducing agents, including clonidine, guanabenz, and reserpine, and calcium channel blockers such as nifedipine.
• Aspirin-containing drugs, nonsteroidal anti-inflammatory drugs (NSAIDS), and sulfinpyrazone may interfere with the blood-pressure-lowering effect of acebutolol.
• Cocaine may reduce the effectiveness of all beta blockers.
• Acebutolol may worsen the problem of cold hands and feet associated with ergot alkaloids, used to treat migraine. Gangrene is a possibility in people taking both an ergot and acebutolol.
• Acebutolol will counteract thyroid hormone replacements.
• Calcium channel blockers, flecainide, hydralazine, contraceptive drugs, cimetidine, propafenone, haloperidol, phenothiazine sedatives (molindone and others), quinolone antibacterials, and quinidine may increase the amount of acebutolol in the bloodstream and lead to increased acebutolol effects.
• Acebutolol should not be taken within 2 weeks of taking a monoamine oxidase inhibitor (MAGI) antidepressant.
• Acebutolol may interfere with the effects of some antiasthma drugs, including theophylline and aminophylline.
• Combining acebutolol with digitalis drugs may result in excessive slowing of the heart, possibly causing heart block.
• If you stop smoking while taking acebutolol, your dose may have to be reduced because your liver will break down the drug more slowly afterward.
• Aluminum salts, barbiturates, calcium salts, cholestyramine, colestipol, ampicillin, and rifampin may reduce the effectiveness of acebutolol.
• Beta blockers may block the effects of epinephrine.
Food Interactions
None known.
Usual Dose
