What is Diamox?
Diamox 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.
Diamox is used in people with certain types of glaucoma to reduce the amount of fluid in the eye, which decreases pressure inside the eye.
Diamox is also used to treat certain types of seizures, and to treat or prevent altitude sickness.
Diamox may also be used for purposes not listed in this medication guide.
You should not use Diamox if you have cirrhosis, severe liver or kidney disease, an electrolyte imbalance, adrenal gland failure, or an allergy to Diamox or sulfa drugs.
