Fexofenadine is used to relieve the symptoms of seasonal allergic rhinitis (hay fever) such as sneezing, itchy, runny or blocked nose and itchy, red and watery eyes.

Fexofenadine belongs to a class of medications called antihistamines. It prevents the release of histamine, a substance that plays a major role in many allergic reactions by dilating blood vessels which makes the vessel walls abnormally permeable.

Phenylephrine(2.5 mg/5 ml)
