Allegra (generic name: fexofenadine; brand names include: Telfast / Fastofen / Fexo-120 / Fexigra) is in a class of medications called antihistamines.

Allegra is indicated for:

relief of symptoms associated with seasonal allergic rhinitis in patients 2 years of age and older;
treatment of uncomplicated skin manifestations of chronic idiopathic urticaria in patients 6 months of age and older.

One dose of long-lasting Allegra provides powerful relief from seasonal allergy symptoms (like sneezing, runny nose, itchy nose or throat, or itchy, watery red eyes) for a full 24 hours. That's four times longer than one dose of most over-the-counter allergy medicines.

Many other seasonal allergy medicines come with warnings that they may cause drowsiness, so patients taking them should be cautious when driving a car or operating machinery. Allegra doesn't have this precaution, because it doesn't make you drowsy.

Recommendations

Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Allegra exactly as directed.

Allegra is usually taken with water once or twice a day. Allegra will work better if it is not taken with fruit juices such as orange, grapefruit, or apple juice. Take Allegra at around the same time(s) every day.

If you miss a dose of Allegra, take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

If you are taking an antacid containing aluminum or magnesium (Maalox, Mylanta, others), take the antacid a few hours before or after Allegra.

Store this medicine at room temperature, away from excess heat and moisture.

Precautions

Before taking Allegra, tell your doctor if:

you are allergic to Allegra or any other medication;
you have or have ever had kidney disease;
you are pregnant, plan to become pregnant, or are breast-feeding.
