Fexofenadine Hydrochloride

Fexofenadine hydrochloride (Allegra®) is a nonprescription medicine commonly used for the treatment of seasonal allergies. It is also approved to treat chronic hives and itching.
As an antihistamine, fexofenadine works by blocking the effects of histamine (a chemical that can cause sneezing, itching, and irritation). This action can help relieve allergy symptoms such as itchy or watery eyes, runny nose, sneezing, and nasal or throat itching.
Fexofenadine comes in tablets, orally disintegrating tablets (ODTs), and oral suspension (liquid). It is taken by mouth, usually once or twice daily. It should never be taken with fruit juices, as juice may affect the way your body handles the medication.
