This medication is used with other medications to treat high pressure inside the eye due to certain types of glaucoma. Acetazolamide belongs to a class of drugs known as carbonic anhydrase inhibitors. It works by decreasing the production of fluid inside the eye. It is also used to decrease a buildup of body fluids (edema) caused by heart failure or certain medications. Acetazolamide can work less well over time, so it is usually used only for a short period.
It has also been used with other medications to treat certain types of seizures (petit mal and unlocalized seizures).
