acetazolamide
a CARBONIC ANHYDRASE INHIBITOR used mainly in the treatment of glaucoma to reduce the pressure inside the eyeball and also as a preventative for epileptic seizures and altitude sickness. It is administered by mouth or injection; side-effects include drowsiness and numbness and tingling of the hands and feet.
Acetazolamide is used to treat glaucoma, a condition in which increased pressure in the eye can lead to gradual loss of vision. Acetazolamide decreases the pressure in the eye. Acetazolamide is also used to reduce the severity and duration of symptoms (upset stomach, headache, shortness of breath, dizziness, drowsiness, and fatigue) of altitude (mountain) sickness. Acetazolamide is used with other medicines to reduce edema (excess fluid retention) and to help control seizures in certain types of epilepsy. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
