Trusopt is an ophthalmic (eye) solution made up of a carbonic anhydrase inhibitor called dorzolamide. We carry both the brand name Trusopt and its generic alternative in 2%.

Trusopt (dorzolamide) is used to help treat an eye condition called open-angle glaucoma. This is a condition that causes eye pain, headache, cloudy vision, and eye redness. Open-angle glaucoma is a condition where the angle in the eye, where the iris meets the cornea, is open and as wide as it should be, however, the eyes drainage canals can become blocked. Over time, this will cause a buildup of fluid in the eye, which causes high pressure.  Additionally, this medication may be used for any condition that causes high pressure to occur in the eye.

Trusopt (dorzolamide) is effective at treating open-angle glaucoma because it is able to decrease the amount of fluid found in the eye. When the fluid in the eye is reduced, it lowers the pressure.

Follow all directions given to you by your doctor, and only your doctor.
