Alternative product listed
Pharmac has listed an alternative from 1 October 2024. It is should be available for order by early October:
- Brand: Emtricitabine/Tenofovir Disoproxil (Teva)
- Presentation: Tab tenofovir disoproxil 245 mg + emtricitabine 200 mg

The brand is Medsafe approved. It may be familiar to people as it has been funded before. People take it in the same way.
The Teva product contains a different salt form of tenofovir disoproxil compared to the Viatris product:
- Viatris: tenofovir disoproxil maleate 300 mg + emtricitabine 200 mg
- Teva: tenofovir disoproxil 245 mg + emtricitabine 200 mg
Tenofovir disoproxil 245 mg is equivalent to tenofovir disoproxil maleate 300 mg. The brands are considered clinically equivalent and can be used interchangeably.
