Fexo 120 is a high-potency antihistamine containing Fexofenadine Hydrochloride used for the effective relief of allergy symptoms without causing significant drowsiness. It is a second-generation H1-receptor antagonist that works by blocking histamine, a natural substance in the body that causes allergic reactions. Produced by Square Pharmaceuticals PLC, here is an updated guide for 2026.

Fexo 120 contains 120 mg of Fexofenadine and is primarily prescribed for:

Chronic Idiopathic Urticaria: Treatment of skin allergies and hives, including the reduction of redness and itching.
Environmental Allergies: Management of symptoms triggered by dust, pet dander, or mold.
