Generic Name: dorzolamide ophthalmic (dor ZOL a mide)
Brand Name: Trusopt
What is Trusopt?
Dorzolamide reduces the amount of fluid in the eye, which decreases pressure inside the eye.
Trusopt (for the eyes) is used to treat open-angle glaucoma and other causes of high pressure inside the eye.
Trusopt may also be used for purposes not listed in this medication guide.
Do not allow the dropper to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.
Do not use any other eye medication unless your doctor has prescribed it for you. If you use another eye medication, use it at least 10 minutes before or after using Trusopt. Do not use the medications at the same time.
Trusopt can cause blurred vision. Be careful if you drive or do anything that requires you to be able to see clearly.

Wash your hands before using the eye drops.
To apply the eye drops:

Use only the number of drops your doctor has prescribed.
Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct.
If you use more than one drop in the same eye, wait about 5 minutes before putting in the next drop.
Wait at least 10 minutes before using any other eye drops that your doctor has prescribed.
Do not allow the dropper tip to touch any surface, including the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye, which can lead to vision loss or serious damage to the eye.
Do not use the eye drops if the liquid has changed colors or has particles in it. Call your doctor for a new prescription.
