    Pataday® is an antihistamine that works two ways. It goes to work on mast cells in the eye. (Mast cells house the histamines that make your eyes itch.) Pataday stabilizes the mast cells, preventing them from releasing histamines.

    Pataday® also blocks histamines that have already been released from attaching to the histamine (H1) receptors in the eye, breaking the chain of allergic reaction.

    The result is decreased histamine release and less allergy symptoms.
