Primary pharmacological mechanism

Treatment of allergic rhinitis (hay fever and perennial allergies), urticaria (hives), allergic skin conditions, and relief of symptoms including sneezing, runny nose, itchy eyes, and skin rashes.

Acrivastine is a selective H1 histamine receptor antagonist that blocks the action of histamine, a substance released during allergic reactions that causes typical allergy symptoms like itching, swelling, and mucus production.

Considered a second-generation antihistamine with lower sedation risk compared to older antihistamines, though some drowsiness may still occur. Should be used with caution when operating machinery. May interact with other medications and is not recommended for certain populations; consult a healthcare provider for personalized advice.
