Acetazolamide, also known under the brand name Diamox, reduces the activity of certain proteins in the body called carbonic anhydrase. The purpose of blocking that protein is to reduce build-up of specific fluids. It is often prescribed for reducing eye pressure in some glaucoma patients through the reduction of the levels of fluid in the eye.

This medication may also be prescribed as a diuretic, or water pill, in congestive heart failure patients. It assists these patients by lowering the levels of fluid built up in the body, AKA edema.

Acetazolamide can also be prescribed to treat some kinds of seizures, to treat and prevent altitude sickness, or other purposes not listed here.

This medication should be taken with a full glass of water. Make sure that you follow your doctor’s dosage instructions very carefully. This mediation may be prescribed as part of a treatment program including other medications, and you may be required to have blood tests regularly during your treatment.
