If you have high eye pressure, your healthcare provider may recommend brimonidine/timolol, a prescription eye drop used to decrease the amount of fluid in the eye. The medication comes in one strength and is used twice a day. Eye allergies, itching, and stinging are among the drug's most common side effects; however, most people are able to use it without any problems.
Brimonidine/timolol (Combigan®) is a prescription eye drop. It contains two different active ingredients: an alpha agonist (brimonidine) and a beta blocker (timolol). It is approved to treat high eye pressure in people with chronic open-angle glaucoma or ocular hypertension.
