Pataday is the first prescription strength one a day eye allergy itch relief drop with no prescription needed. 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.

A prescription strength eye drop used to treat dry eye itching that is caused by allergies. With no prescription needed, it starts working in two ways on the 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. Less histamines means less allergy eye itch!
