Important Note
The following information is intended to supplement, not substitute

that use of the drug is safe, appropriate, or effective for you.
Consult your healthcare professional before using this drug.
Uses
Allegra contains an antihistamine and decongestant used to relieve
allergy symptoms such as itchy red eyes, stuffy nose and throat
irritation.
How to Use
Take Allegra by mouth on an empty stomach 1 hour before or two hours
after meals as directed, usually twice daily. Taking Allegra with
a high fat meal can decrease its effectiveness. Do not take antacids
containing aluminum and magnesium within 2 hours of taking this
medication. 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 (see Drug Interactions).
Side Effects
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. Tell your doctor immediately if any of these highly
unlikely but very serious side effects occur: fainting, irregular
heartbeat. Although drowsiness is very uncommon at usual doses under
normal circumstances, be aware that drowsiness may occur and may
effect the ability to perfom tasks requiring alertness (e.g., driving).
If you notice other effects not listed above, contact your doctor
or pharmacist.
Precautions
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
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.
Drug Interactions
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 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.
Overdose
If overdose is suspected, contact your local poison control center
or emergency room immediately. Symptoms of overdose may include
irregular or unusually slow or fast heartbeat, unusual nervousness
or excitement, rapid breathing, confusion, hallucinations, and seizures.
Notes
Do not share this medication with others.
Missed Dose
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.
