Brimonidine (patient information)

# Why is this medication prescribed?
Ophthalmic brimonidine is used to lower pressure in the eyes in patients who have glaucoma (high pressure in the eyes that may damage nerves and cause vision loss) and ocular hypertension (pressure in the eyes that is higher than normal but not high enough to cause vision loss). Brimonidine is in a class of drugs called alpha adrenergic agonists. Brimonidine works by decreasing the amount of fluid in the eyes.
How should this medicine be used?
Ophthalmic brimonidine comes as a solution (liquid) to instill in the eyes. It is usually instilled in the affected eye(s) three times a day. Use brimonidine eye drops at around the same times every day, and try to space your 3 daily doses about 8 hours apart. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use brimonidine eye drops exactly as directed. Do not use more or less of them or use them more often than prescribed by your doctor.
Brimonidine eye drops may control your condition, but will not cure it. Continue to use brimonidine eye drops even if you feel well. Do not stop using brimonidine eye drops without talking to your doctor.

# To instill the eye drops, follow these steps:
- Wash your hands thoroughly with soap and water.
- Check the dropper tip to make sure that it is not chipped or cracked.
- Avoid touching the dropper tip against your eye or anything else; eye drops and droppers must be kept clean.
- While tilting your head back, pull down the lower lid of your eye with your index finger to form a pocket.
- Hold the dropper (tip down) with the other hand, as close to the eye as possible without touching it.
- Brace the remaining fingers of that hand against your face.
- While looking up, gently squeeze the dropper so that a single drop falls into the pocket made by the lower eyelid. Remove your index finger from the lower eyelid.
- Close your eye for 2 to 3 minutes and tip your head down as though looking at the floor. Try not to blink or squeeze your eyelids.
- Place a finger on the tear duct and apply gentle pressure.
- Wipe any excess liquid from your face with a tissue.
- If you are to use more than one drop in the same eye, wait at least 5 minutes before instilling the next drop.
- Replace and tighten the cap on the dropper bottle. Do not wipe or rinse the dropper tip.
- Wash your hands to remove any medication.
