About Allegra 120 Tablet
Allegra 120 Tablet contains Fexofenadine 120 mg. Fexofenadine is an antihistamine used to relieve allergy symptoms. It eases sneezing, a runny or itchy nose, and itchy, watery eyes caused by hay fever, as well as itching and rashes from long-lasting hives (urticaria). It is less likely to make you sleepy than older antihistamines. It is usually taken once a day.

How to use
Take it exactly as your doctor prescribed. Swallow the tablet whole with water, preferably before a meal. Do not take it with fruit juice such as orange, grapefruit or apple juice.
How it works
Fexofenadine blocks histamine, a chemical the body releases during an allergic reaction that causes sneezing, itching, a runny nose and hives. It does not easily enter the brain, so it seldom causes drowsiness.
