Allegra Drug Information

• Allegra Overview

  Fexofenadine is an antihistamine used to relieve allergy symptoms such as watery eyes, runny nose, itching eyes/nose, sneezing, hives, and itching. It works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction.

• How to Use Allegra

  If you are taking the over-the-counter product to self-treat, read all directions on the product package before taking Allegra. If you have any questions, consult your pharmacist. If your doctor has prescribed Allegra, take it as directed, usually 2 times daily (every 12 hours). If you are using the liquid form of Allegra, shake the bottle well before each dose and measure the dose carefully using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. Take the tablet/capsule or liquid form of Allegra with or without food. If you are using the rapidly-dissolving tablet, take it on an empty stomach. Allow the rapidly-dissolving tablet to dissolve on the tongue and then swallow, with or without water. Do not remove the tablet from the blister pack until right before using. If you need a liquid to take Allegra (such as when taking the tablets/capsules), then take Allegra with water. Do not take with fruit juices (such as apple, grapefruit, or orange) since they may decrease the absorption of Allegra. The Dosage of Allegra is based on your age, medical condition, and response to treatment. Do not increase your dose or take Allegra more often than directed. Do not take antacids containing aluminum and magnesium within 2 hours of taking Allegra. These antacids can decrease the absorption of fexofenadine. Tell your doctor if your condition does not improve or if it worsens.
