Uses for epinastine

Epinastine ophthalmic (eye) solution is used to prevent itching of the eye caused by a condition known as allergic conjunctivitis. It works by preventing the effects of certain inflammatory substances, which are produced by cells in your eyes and sometimes cause allergic reactions.

This medicine is available only with your doctor's prescription.
