How to use Timolol ophthalmic

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Do not use timolol ophthalmic while wearing contact lenses. Timolol ophthalmic may contain a preservative that can discolor soft contact lenses. Wait at least 15 minutes after using this medicine before putting in your contact lenses.

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.

It may take a few weeks before your symptoms improve. Keep using the medication as directed and tell your doctor if your symptoms do not improve after 4 weeks of treatment.

If you need surgery, including 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.

You should not stop using this medicine suddenly. Follow your doctor's instructions about tapering your dose.

Store at room temperature away from moisture, heat, and light. Do not freeze. Keep the bottle tightly closed when not in use. Keep each single-use ampule inside its foil pouch until you are ready to use your dose.

A single-use ampule is for one use only. Throw it away after one use, even if there is still medicine left inside.

Warnings

You should not use timolol ophthalmic if you have asthma or severe COPD, or a serious heart condition (such as "sick sinus syndrome," 2nd or 3rd degree "AV block," severe heart failure, or very slow heartbeats).

Side effects may occur if this medicine is absorbed into your bloodstream. Call your doctor right away if you have: chest pain, trouble breathing, slow heartbeats, muscle weakness, numbness or coldness in your hands or feet, unusual mood or behavior changes, or severe dizziness.
