Bimatoprost is used 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 can help prevent blindness. This medication works by regulating the flow of fluid within the eye to maintain a normal pressure.

Read the Patient Information Leaflet if available from your pharmacist before you start using bimatoprost and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Use this medication in the affected eye(s) as directed by your doctor, usually once a day in the evening. Do not use bimatoprost more often because it will not work as well.

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 your eye drops. Wait at least 15 minutes after each dose before putting your lenses back in.

Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch. 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. This will prevent the medication from draining out. Try not to blink and do not rub your eye. Repeat these steps for your other eye if so directed.

Do not rinse the dropper. Replace the dropper cap after each use, and keep the cap tightly closed.

If you are using another kind of eye medication (such as drops or ointments), wait at least 5 minutes before applying 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.

Use this medication regularly in order to get the most benefit from it. Remember to use it at the same time each day. Keep using bimatoprost even if you feel well. Most people with glaucoma or high pressure in the eye do not have symptoms.

Burning/stinging/irritation/redness of the eye, feeling as if something is in your eye, dry eyes, watering eyes, and increased sensitivity to light may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

This medication may slowly (over months to years) cause brown discoloration of the colored portion of the eye (iris). If you are using bimatoprost in only one eye, only that iris may change color. An increase in eyelash number/length/thickness, darkening of the eyelashes/eyelids, or eyelid changes may also occur in the treated eye. These changes may be permanent, but the long-term effects are uncertain. Notify your doctor if this occurs, and schedule regular eye exams to monitor it.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

• vision changes
