What is Combigan?
Combigan contains a combination of brimonidine and timolol.Brimonidine 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.
Combigan eye drops are used to treat open-angle glaucoma or ocular hypertension (high pressure inside the eye).
Combigan may also be used for purposes not listed in this medication guide.
You should not use Combigan eye drops if you have a history of asthma or chronic obstructive pulmonary disease (COPD), or a serious heart condition such as "AV block," severe heart failure, or slow heartbeats that have caused you to faint.
Combigan should not be given to a child younger than 2 years old.
