How should I use timolol ophthalmic?

Use timolol ophthalmic exactly as it was prescribed for you. Do not use the medication in larger amounts, or use it for longer than recommended by your doctor. Follow the instructions on your prescription label.

Wash your hands before using the eye drops.

Do not use this medication while you are wearing contact lenses. Timolol ophthalmic may contain a preservative that can be absorbed by soft contact lenses. Wait at least 15 minutes after using timolol before putting your contact lenses in.

To apply the eye drops:

• Tilt your head back slightly and pull down your lower eyelid. Hold the dropper above the eye with the dropper tip down. Look up and away from the dropper as you squeeze out a drop, then close your eye.
• Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct. If you use more than one drop in the same eye, wait about 5 minutes before putting in the next drop.
• Do not allow the dropper tip to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.

Do not use the eye drops if the liquid has changed colors or has particles in it. Call your doctor for a new prescription.

If you need to have any type of surgery, especially eye surgery, tell the surgeon ahead of time that you are using timolol ophthalmic. You may need to stop using the medicine for a short time.

Store this medication at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.
