Cosopt

Generic name: Dorzolamide And Timolol Ophthalmic
Brand names: Cosopt
Drug class: Ophthalmic glaucoma agents

Usage of Cosopt

Cosopt eye drops contain a combination of dorzolamide and timolol. Dorzolamide reduces the amount of fluid in the eye, which decreases pressure inside the eye. Timolol is a beta-blocker that also reduces pressure inside the eye.

Cosopt is a prescription eye drop solution used to treat open-angle glaucoma or ocular hypertension when a beta-blocking medicine alone does not work to control the eye pressure.

It is not known if Cosopt is safe and effective in children 2 years of age and younger.
