What is Combigan?
Combigan contains brimonidine and timolol.
Brimonidine is an alpha-agonist that 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 is used to treat glaucoma or ocular hypertension (high pressure inside the eye).
Combigan may also be used for other purposes not listed in this guide.

How should I use Combigan?
Use Combigan exactly as prescribed by your doctor. Do not use it in larger amounts or for longer than recommended. Follow the directions on your prescription label.
Wash your hands before using the eye drops. Do not use Combigan while you are wearing contact lenses. Combigan may contain a preservative that can be absorbed by soft contact lenses. Wait at least 15 minutes after using the eye drops before putting your contact lenses in.
To apply the eye drops:
Tilt your head back slightly and pull down your lower eyelid. Hold the Combigan dropper above the eye with the dropper tip down. Look up and away from the dropper as you squeeze out a drop, then close your eye.
Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct.
If you use any other eye medications, wait about 5 minutes after using Combigan eye drops before using the other medication.
