Allegra allergy contains an antihistamine and decongestant used to relieve allergy symptoms such as itchy, red eyes, stuffy nose and throat irritation.
Take Allegra allergy by mouth on an empty stomach 1 hour before or two hours after meals as directed, usually twice daily. Taking this medicine with a high fat meal can decrease its effectiveness. Do not take antacids containing aluminum and magnesium within 2 hours of taking Allegra allergy. Swallow the medicine whole. Do not crush or chew the tablet, and do not take more than prescribed. Do not take this product within 14 days after stopping an MAO Inhibitor.
Nausea, stomach upset, trouble sleeping, headache, or cold symptoms may occur. If these persist or worsen, notify your doctor promptly. Unlikely but report promptly: dizziness, mental/mood changes, fast heartbeat, fever. Very unlikely but report promptly: irregular pulse, seizures, fainting. Although drowsiness is very uncommon at usual doses under normal circumstances, be aware that Allegra allergy may have such an effect before performing tasks requiring alertness (e.g., driving). If you notice other effects not listed above, contact your doctor or pharmacist.
Tell your doctor your medical history, including: allergies, kidney/urinary problems, enlarged prostate, glaucoma (narrow angle), severe high blood pressure, heart disease, diabetes, thyroid problems (hyperthyroid). Limit alcohol intake, as it may aggravate drug side effects. Allegra allergy should be used only when clearly needed during pregnancy. Discuss the risks and benefits with your doctor. The pseudoephedrine in this product is excreted into breast milk. Consult your doctor before breast-feeding. Caution is advised when this product is used in the elderly since this group may be more sensitive to side effects.
Tell your doctor of all nonprescription and prescription medication you may use, especially: MAO inhibitors (e.g., selegiline, furazolidone, phenelzine, tranylcypromine, moclobemide, procarbazine, linezolid), certain blood pressure drugs (e.g., methyldopa, mecamylamine, reserpine, prazosin), digoxin, all adrenaline-like drugs. Report other drugs which affect the heart rhythm (QTc prolongation), such as: dofetilide, pimozide, quinidine, sotalol, procainamide, sparfloxacin, "water pills" (diuretics such as furosemide or hydrochlorothiazide). Ask your doctor or pharmacist for more details. Check the labels carefully on all nonprescription products, such as cough-and-cold medicines which contain antihistamines and decongestants. Consult your pharmacist. Do not take Allegra allergy for several days before any allergy testing since test results can be affected. Do not start or stop any medicine without doctor or pharmacist approval.
If you miss a dose, use it as soon as you remember. If it is near the time of the next dose, skip the missed dose and resume your usual dosing schedule. Do not "double-up" the dose to catch up.
Store at room temperature between 68 and 77 degrees F (20-25 degrees C) away from sunlight and moisture.
