Allegra 120mg Tablet contains Fexofenadine, a second-generation antihistamine used to relieve symptoms of allergic rhinitis (hay fever) and chronic urticaria (hives). It works by blocking histamine, a chemical responsible for allergy symptoms such as sneezing, runny nose, itchy eyes, and skin rashes. Unlike older antihistamines, Allegra is non-drowsy and provides long-lasting relief.

Uses of Allegra 120mg Tablet

• Allergic Rhinitis: Treats sneezing, runny nose, itchy/watery eyes, and nasal congestion caused by seasonal allergies.
• Chronic Urticaria: Relieves itching, swelling, and redness in conditions like hives.
• Other Allergic Reactions: May be used for skin allergies and insect bites (as prescribed by a doctor).

How Allegra 120mg Works

Allegra contains Fexofenadine, an antihistamine that blocks H1 histamine receptors in the body. By preventing histamine from binding to these receptors, the tablet helps reduce allergy symptoms without causing significant drowsiness.

Dosage & Administration

• Ideally, take the tablet with water at the same time every day.
• It is best to take before food for better absorption, but it can also be taken with food.
