Alphagan eye drops contain the active ingredient brimonidine, which is a type of medicine called an alpha agonist. It works by stimulating alpha receptors found on blood vessels in the eye. Brimonidine eye drops are used to treat glaucoma in people who cannot use beta-blocker eye drops. They may also be used in conjunction with other types of eye drop, for example beta-blockers or prostglandin analogues, to treat glaucoma in people whose eye pressure has not been lowered sufficiently with one medicine. Eye drops are used to produce a local effect in the eye, with minimal effect on other parts of the body.
Wash your hands before using the eye drops. To apply the Alphagan eye drops you have to tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop. Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct. Use only the number of drops your doctor has prescribed. If you use more than one drop, wait about 5 minutes between drops. Wait at least 5 minutes before using any other eye drops your doctor has prescribed. Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems. Do not use the Alphagan eye drops if the liquid has changed colors or has particles in it.
