What's in allergy eye drops?

ANSWER

The key ingredient in allergy eye drops is a drug called an antihistamine, which blocks histamines -- which are released when you have an allergic reaction -- from doing their work. That prevents allergy symptoms. Some newer allergy eye drops, called mast-cell stabilizers, work by stopping your body from making histamines in the first place.
