Acetazolamide Oral

Why this is used

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 water 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.

How to take it

Acetazolamide comes as a tablet and capsule to take orally. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take acetazolamide exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. If you are taking the extended-release (long-acting) form of acetazolamide (Diamox Sequels), do not crush or chew the capsules.
