Patient summary
Acetazolamide 250mg tablets, used in the management of glaucoma, oedema and acute mountain sickness. A carbonic anhydrase inhibitor taken by mouth.
Mechanism of action
Acetazolamide is a carbonic anhydrase inhibitor. By blocking this enzyme in the eye, it reduces the production of aqueous humour, thereby lowering intraocular pressure. It also acts as a mild diuretic by inhibiting bicarbonate reabsorption.
Diamox is an established form of acetazolamide, used for the management of glaucoma, oedema and acute mountain sickness. The medication is supplied as a 250mg tablet. It acts as a standard option for patients needing to control fluid levels in the eye and throughout the body.
Buying Diamox online
While the original brand remains the standard for many, generic acetazolamide, much of which is produced in India, provides a more affordable alternative for those managing persistent symptoms. Expats and residents can order the required supply online with delivery across the region.
Do I get the original Diamox?
No. SGMeds ships a generic with the same active ingredient (acetazolamide) at the same strength, not the original Diamox made by Mercury Pharma. We use the brand name so you can find the medicine, and the generic's manufacturer varies with stock.
What is Diamox for?
Diamox is used for glaucoma, swelling (oedema) and acute mountain sickness.
How is Diamox priced?
Diamox comes in a 250mg strength, in packs of 30 to 360 tablets. Each option's price is shown on this page in Singapore dollars, converted from US dollars, so the exchange rate can change the final amount. Larger packs work out cheaper per tablet.
