Product Overview
Effective treatment to prevent and ease symptoms of altitude sickness. 250mg tablets
Description
Acetazolamide 250 mg Tablets are a prescription-only medicine used to treat a range of conditions where reduction of fluid pressure or abnormal electrical activity is required. Acetazolamide belongs to a group of medicines called carbonic anhydrase inhibitors.
It is commonly prescribed for:
- Glaucoma – to reduce pressure inside the eye
- Fluid retention (oedema) – acts as a mild diuretic
- Epilepsy – as an add-on treatment to help control seizures
By reducing the production of certain fluids in the body, acetazolamide helps lower eye pressure, remove excess fluid, and support seizure control when used under medical supervision.
✔ Multi-use prescription medicine
✔ Used in glaucoma, epilepsy, and fluid retention
✔ Suitable for adults and children (dose dependent, prescribed use)
