    • What is this medication and its most common uses?

      Xalatan is an eye drop used to lower pressure in the eye in people with open-angle glaucoma or high pressure in the eye.

    • What should I know when beginning and continuing on this medication?

      How does this medication work?

      Increased pressure in the eye and glaucoma can result when the fluid that flows through and nourishes the lens and cornea (the clear front part of the eye) cannot drain normally. Xalatan is thought to lower pressure in your eye by enhancing the outflow of this fluid.

      What are the beneficial effects of this medication and when should I begin to have results?

      What: By reducing the pressure in your eye, Xalatan may help reduce the risk of developing glaucoma-related vision loss.
