Generic Name: Timolol

  • What is this medication and its most common uses?

    Timoptic-XE 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. Timoptic-XE is thought to lower the pressure in your eye by reducing the production 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, Timoptic-XE may help reduce the risk of developing glaucoma-related vision loss.

    When: Everyone responds differently to treatment, so try to be patient and follow your healthcare provider's directions. It is important that you use Timoptic-XE exactly as your healthcare provider has prescribed.

    How do I know it is working?

    Your healthcare provider may examine your eyes or perform certain tests to check how well this medication is working.
