Why is this medication prescribed?

Allegra is prescribed primarily for the relief of allergy symptoms. It is an antihistamine that helps manage symptoms such as: sneezing, runny or itchy nose, itchy or watery eyes, Itchy throat or palate Hives and other skin rashes. Fexofenadine works by blocking the effects of histamine, a substance in the body that causes allergic symptoms.
