Bimatoprost Ophthalmic (patient information)

Why this medication is prescribed

Bimatoprost is used to treat eye conditions, including glaucoma and ocular hypertension, in which increased pressure can lead to a gradual loss of vision. Bimatoprost is used for patients who cannot use other eye medications for their condition or whose eye condition has not responded to another medication. Bimatoprost is in a class of medications called prostamides. It lowers pressure in the eye by increasing the flow of natural eye fluids out of the eye.

How this medication should be used

Bimatoprost comes as an eyedrop to apply to the eye. It is usually applied to the affected eye(s) once a day in the evening. To help you remember to use bimatoprost, use it around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use bimatoprost exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

Bimatoprost controls glaucoma and ocular hypertension but does not cure them. Continue to use bimatoprost even if you feel well. Do not stop using bimatoprost without talking to your doctor.

To apply the eyedrops, follow these steps:

1. Wash your hands thoroughly with soap and water.
2. Use a mirror or have someone else put the drops in your eye.
3. Make sure the end of the dropper is not chipped or cracked.
4. Avoid touching the dropper against your eye or anything else.
5. Hold the dropper tip down at all times to prevent drops from flowing back into the bottle and contaminating the remaining contents.
6. Lie down or tilt your head back.
7. Holding the bottle between your thumb and index finger, place the dropper as near as possible to your eyelid without touching it.
8. Brace the remaining fingers of that hand against your cheek or nose.
9. With the index finger of your other hand, pull the lower lid of the eye down to form a pocket.
10. Drop the prescribed number of drops into the pocket made by the lower lid and the eye. Placing the drops on the surface of the eyeball can cause stinging.
11. Close your eye and press lightly against the lower lid with your finger for 2-3 minutes to keep the medication in the eye. Do not blink.
12. Replace and tighten the cap right away. Do not wipe or rinse it off.
13. Wipe off any excess liquid from your cheek with a clean tissue. Wash your hands again.
