Combigan® (brimonidine/timolol) is a prescription eye drop used to lower the pressure in the eyes (intraocular pressure). Specifically, it is approved to lower eye pressure in people with the following conditions:
Ocular hypertension (high eye pressure that is not accompanied by changes in vision or damage to the optic nerve, as would happen with glaucoma).
Combigan can be used by itself or, if necessary, combined with other types of glaucoma medications or treatments. The eye drop can also be used "off-label" to treat acute angle-closure glaucoma; however, this is not an approved use of the drug.
