Acetazolamide: Brand change

Brand change Active

The funded brand of acetazolamide Tab 250 mg is changing from Diamox to Medsurge.

What is changing?

Medsurge was awarded the tender for acetazolamide tab 250 mg in November 2024. 

The Medsurge brand of acetazolamide tab 250 mg was listed from 1 April 2025. However, due to manufacturing and regulatory delays this brand is not yet available.

Diamox acetazolamide tab 250 mg can continue to be accessed until supply of the Medsurge brand of acetazolamide tab 250 mg becomes available. 

Pharmac is working with both Medsafe and Medsurge. No supply issue is anticipated.
