Pataday Eye Drops Extra Strength, 2.5 ml (3 Pack)

Pataday works two ways. It goes to work on mast cells in the eye and 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. Less histamines means less allergy eye itch! Pataday is the first once daily eye allergy itch relief drop that's available without a prescription. A single drop of Pataday Once Daily Relief works directly on the cells that make your eyes itch. It's fast relief that lasts all day.
