Timolol is used to treat glaucoma, a condition in which increased pressure in the eye can lead to gradual loss of vision. This eye medication decreases the pressure in the eye.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Glaucoma is a group of diseases that can damage the eye, resulting in vision loss. Read all about glaucoma.

Glaucoma can damage the optic nerve on the back of the eye. However, with early treatment, you can often protect your eyes against serious vision loss.

HOW should Timolol be used?

This glaucoma treatment comes as eye drops and eye gel. They are usually are applied once or twice a day, at evenly spaced intervals, until pressure in your eyeball is controlled (about 4 weeks). Then you may be able to use it once a day.

Timolol gel usually is applied once a day. Follow the directions on your prescription label carefully, and ask doctor or pharmacist to explain any part you do not understand. Use exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Timolol controls glaucoma but does not cure it. Continue to use the drop even if you feel well. Do not stop using it without talking to your doctor.
