Glaucoma medications are medicated eye drops or gels that are dropped onto the surface of the eye one or more times each day. The medicine is then absorbed into the eye where it interacts with the structures inside the eye. Eye medications either decrease the production of eye fluid (aqueous) or help clean out the drainage system so it works better. Once started, medications are usually used for many years, and sometimes for the remainder of your life. To be effective, medications must be used every day. A common reason patients go blind from glaucoma is a failure to use the medications on a daily basis. Most glaucoma medications only work for 6-12 hours, so regular dosing is important for them to be effective. If doses are missed, the eye pressure will begin to increase within just a few hours. If you take medications, it is important that you pay attention to how much is in the bottle so that you can get refills at the pharmacy regularly. Try to get to the pharmacy BEFORE the medicine runs out so that you don’t miss any days of treatment. Never stop using a medication without first calling your doctor and discussing with them the problems you are having (side effects, cost, etc.).
To avoid confusion, it is very helpful if you know the exact names of your medications and take the bottles with you when you come in for an eye pressure check at the eye doctor’s office.
