Acetazolamide (500mg)

Acetazolamide (500mg) — Uses and Benefits

Acetazolamide is mainly used to treat raised pressure inside the eye and to prevent altitude sickness, among other conditions.

WHAT THIS MEDICINE IS USED FOR

• Open-angle and certain other types of glaucoma to reduce eye pressure
• Prevention and treatment of acute mountain sickness (altitude sickness)
• As an add-on treatment for certain types of epilepsy/seizures
• To reduce fluid retention (edema) in some heart or drug-related conditions
• Certain rare conditions causing increased pressure in the brain

HOW IT WORKS

• It blocks an enzyme called carbonic anhydrase
• This reduces the amount of fluid produced inside the eye, lowering eye pressure
• It also changes the balance of acid and fluid in the body, which helps in altitude sickness and fluid retention
• In the brain, this action helps control certain types of seizures

WHAT IT IS NOT USED FOR

• It is not a painkiller and does not treat headaches directly
• It is not used for common infections
• It is not a first-choice medicine for routine seizures without specialist advice
