What is acetazolamide?

Acetazolamide reduces the activity of a protein in your body called carbonic anhydrase. Blocking this protein can help reduce the build-up of certain fluids in the body.

Acetazolamide is used in people with certain types of glaucoma to reduce the amount of fluid in the eye, which decreases pressure inside the eye.

Acetazolamide is also used as a diuretic ("water pill") in people with congestive heart failure, to reduce the build-up of fluid in the body. This build-up is called edema.

Acetazolamide is also used to treat certain types of seizures, and to treat or prevent altitude sickness.
