Scot-Tussin Allergy is used to temporarily relieve symptoms associated with allergic rhinitis (hay fever), seasonal allergies, and other respiratory allergies. Common symptoms addressed include sneezing, runny nose, itchy/watery eyes, and nasal congestion.
As an antihistamine medication, it works by blocking the effects of histamine—a substance produced by the body during allergic reactions. By inhibiting histamine, the medication helps reduce allergic symptoms.
