How should I use dorzolamide and timolol ophthalmic?

Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.

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

This medication comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Wash your hands before using the eye drops.

To apply the eye drops:

  • Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop.
  • Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
  • Use only the number of drops your doctor has prescribed. If you use more than one drop, wait about 5 minutes between drops.
  • Wait at least 10 minutes before using any other eye drops your doctor has prescribed.

Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.

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

Tell your doctor right away if you have any eye injury or infection, or if you need to have any type of surgery, especially eye surgery. You may need to stop using dorzolamide and timolol ophthalmic for a short time.
