Pataday Twice Daily Eye Allergy Itch Relief Eye Drops 5 ml

Itchy Eyes? Meet the Invisible Enemies. Did you know there are thousands of allergens in every cubic yard of air? Pollen, ragweed, and grass are the triggers we might think of first. But you don't have to set foot outdoors to have your day ruined by itchy allergy eyes. Pet dander and animal hair are among the most common indoor allergens. That's why there's Pataday. Pataday is made to relieve the itch caused by these everyday culprits—both indoor and out. About Pataday Prescription strength Pataday features the ingredient doctors prescribe most for itchy allergy eyes. And now, no prescription is needed. How does Pataday work? Pataday 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.
