Brimonidine Ophthalmic (patient information)

Why this medication is 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 this medication should be used

Brimonidine ophthalmic 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 three 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 use the eye drops, follow these steps:

Wash your hands thoroughly with soap and water.
Use a mirror or have someone else put the drops in your eye.
Remove the protective cap. Make sure that the end of the dropper is not chipped or cracked.
Avoid touching the dropper tip against your eye or anything else.
Hold the dropper tip down at all times to prevent drops from flowing back into the bottle and contaminating the remaining contents.
Lie down or tilt your head back.
Holding the bottle between your thumb and index finger, place the dropper tip as near as possible to your eyelid without touching it.
Brace the remaining fingers of that hand against your cheek or nose.
With the index finger of your other hand, pull the lower lid of the eye down to form a pocket.
Drop the prescribed number of drops into the pocket made by the lower lid and the eye. Placing drops on the surface of the eyeball can cause stinging.
Close your eye and keep it closed for a few minutes. Do not blink.
Replace and tighten the cap right away. Do not wipe or rinse it off.
Wipe off any excess liquid from your cheek with a clean tissue. Wash your hands again.
