Description
Allevia 120 mg – 30 Tablets are an over-the-counter antihistamine medicine indicated for the symptomatic relief of hayfever and allergic rhinitis symptoms in adults and children aged 12 years and over. Each film-coated tablet contains 120 mg of fexofenadine hydrochloride, a second-generation, non-drowsy H1 antihistamine that works by blocking the effects of histamine — a natural chemical released during allergic reactions that causes sneezing, itching, nasal congestion and watery eyes.
Allevia starts to relieve symptoms within approximately one hour of oral administration and provides up to 24 hours of relief with once-daily dosing, helping adults and adolescents manage seasonal and perennial allergies without frequent dosing. The tablets are also lactose-free and gluten-free in most formulations, making them suitable for a range of dietary needs.

- Take one tablet (120 mg) once daily, preferably with water before a meal.
