Ophthalmic timolol is used to treat glaucoma, a condition in which increased pressure in the eye can lead to gradual loss of vision. Timolol is in a class of medications called beta-blockers. It works by decreasing the pressure in the eye.
Ophthalmic timolol comes as a solution (liquid) and an extended-release (long-acting) gel-forming solution (liquid that thickens to a gel when instilled in the eye). Timolol eye drops are usuallyinstilled once or twice a day, at evenly spaced intervals, until pressure in the eye is controlled (about 4 weeks). Then it may be instilled once a day. Timolol gel-forming solution is usually instilled 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 timolol exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.
