How It Works
This medicine works by competitively blocking histamine H1 receptors on cells in the respiratory tract, blood vessels, and skin. Histamine is a chemical released during allergic reactions that causes sneezing, itching, watery eyes, and runny nose. By blocking H1 receptors, this medicine reduces these allergic symptoms.
