Uses

Carteolol is used alone or with other medications to treat high pressure inside the eye due to glaucoma (open-angle type) or other eye diseases (such as ocular hypertension). Lowering high pressure inside the eye helps to prevent blindness. Carteolol is a beta blocker. It is thought to work by reducing the amount of fluid made in the eye.

How to use Carteolol HCL Drops

Use this medication in the affected eye(s) as directed by your doctor, usually twice daily. Use in the eye only. Do not swallow or inject.

Dosage is based on your medical condition and response to treatment. Follow your doctor's directions on how to use this medication.

To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.

Before using, check this product visually for brown discoloration, cloudiness, or particles. If any of these is present, do not use the eye drops.

The preservative in this product may be absorbed by contact lenses. If you wear contact lenses, remove them before using your eye drops. Wait at least 15 minutes after using this medication before putting your contact lenses back in.

Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over the eye and place one drop in the pouch. Look downward and gently close your eyes for 1-2 minutes. Place one finger at the corner of the eye near the nose and apply gentle pressure. This will prevent the medication from draining out. Try not to blink and do not rub the eye. Repeat these steps for your other eye if directed by your doctor.

Do not rinse the dropper. Replace the dropper cap after each use.

If you are using another kind of eye medication (such as drops or ointments), wait at least 10 minutes before applying other medications. Use the eye drops before eye ointments to allow the eye drops to enter the eye.

Wait several minutes for your vision to clear before driving or operating machinery.

Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same times each day. Keep using this medication even if you feel well. Most people with high pressure in the eye do not feel sick.
