Timolol Maleate Information
(tye' moe lole)
- Wash your hands thoroughly with soap and water.
- If you are using the gel-forming solution, invert the container and shake it once. (There is no need to shake the eye-drops.) Make sure that the end of the dropper 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.
- If you are using the eye drops, gently squeeze the dropper so that a single drop falls into the pocket made by the lower eyelid. If you are using the gel-forming solution, check the directions that came with your medication to see whether you should push the bottom of the bottle so that a single drop falls out or press a specially marked area on the side of the bottle. If you are using the type of bottle that must be pushed from the bottom, be careful not to squeeze the sides of the bottle. 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.
