Zyrtec appears to compete with the histamine molecule (produced by mast cells) for cellular binding sites... so the histamine lacking for an available binding site does not have a chance to trigger a series of events which result in the allergic symptoms we experience.
It helps block the production of "histamines" a normal component of the body's chemical response to allergens, and therfeore helps reduce inflammation and secretions.
