Cosopt® (dorzolamide/timolol) is a medication approved for the treatment of high eye pressure due to certain medical conditions. Specifically, people with intraocular hypertension and acute open-angle glaucoma can use Cosopt. It works by reducing the amount of fluid the eye produces, which in turn reduces pressure.
If you are using any other kind of drops in addition to Cosopt, make sure that you separate the doses of each medication by at least 10 minutes. In addition, if you wear soft contact lenses, you will need to remove them before applying a dose and wait at least 15 minutes before reinserting the lenses.
Although Cosopt is approved to treat one specific kind of glaucoma, it may be prescribed in an "off-label" fashion to treat acute angle-closure glaucoma. (Off-label means that the drug is being used to treat a condition for which it is not approved.)
