Uses

This medication is used to treat open-angle glaucoma or high fluid pressure in the eye. Lowering high fluid pressure in the eye reduces the risk of vision loss, nerve damage, or blindness. This medication lowers pressure by allowing better fluid drainage from within the eye and also by reducing the amount of fluid formed in the eye. It is known as an alpha agonist.

This drug is not recommended for use in children less than 2 years of age due to an increased risk of serious side effects such as very slowed breathing. Ask the doctor or pharmacist for details.

How to Use This Medication

Use this medication in the affected eye(s) as directed by your doctor, usually three times daily.

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.

If you are wearing contact lenses, remove them before using this medication. After applying this medication, wait at least 15 minutes before putting in your contact lens.

Tilt your head back, look upward and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and insert one drop. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of your eye (near the nose) and apply gentle pressure. Try not to blink and do not rub your eye. This will prevent the medication from draining out. Repeat these steps for your other eye if so 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 5 minutes before applying the other medications. Use 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.

Keep using this medication even if you feel well. Use this medication regularly in order to get the most benefit from it. Remember to use it at the same times each day. Do not stop using this medication without consulting your doctor.

Inform your doctor if your condition worsens.
