Why Cosopt Eyedrops are prescribed?
The combination of dorzolamide and timolol is used to treat eye conditions, including glaucoma and ocular hypertension, in which increased pressure can lead to a gradual loss of vision. Dorzolamide and timolol are used for patients whose eye condition has not responded to another medication. Dorzolamide is in a class of medications called topical carbonic anhydrase inhibitors. Timolol is in a class of medications called topical beta-blockers. Dorzolamide and timolol lower pressure in the eye by decreasing the production of natural fluids in the eye.
How should this medicine be used?
The combination of dorzolamide and timolol comes as a solution (liquid) to instill in the eye. It is usually instilled in the affected eye(s) twice a day.
