Methazolamide reduces the activity of a protein in your body called carbonic anhydrase. Blocking this protein can help reduce the amount of fluid in the eye, which decreases pressure inside the eye.

Methazolamide is used to lower pressure inside the eye (intraocular pressure) in people with certain types of glaucoma.

Methazolamide 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.

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