Allegra (Fexofenadine) is used to relieve hay fever and allergy symptoms, including runny nose; sneezing; and red, itchy, tearing eyes. Fexofenadine is in a class of medications called antihistamines. It works by blocking histamine, a substance in the body that causes allergic symptoms. Fexofenadine may cause less drowsiness than other antihistamines..
