Fexofenadine is an antihistamine used to treat allergy symptoms like runny nose, sneezing, watery eyes, and irritation in the nose, throat, and mouth. It’s available as an over-the-counter (OTC) and prescription medication under the brand name Allegra. Fexofenadine is the main ingredient in the tablet and liquid form of Allegra. It’s typically taken once or twice daily with water to relieve allergy symptoms for either a limited time or long-term.
Histamine is a naturally occurring chemical in the body that leads to allergy symptoms. Fexofenadine reduces allergy symptoms by blocking the effects of histamines.
A healthcare provider will evaluate your medical history, current health status, and symptoms to determine if fexofenadine is appropriate for you. You may qualify if you have been diagnosed with seasonal allergies.
