Hello, I recently purchased Tenvir. I later realized that Tenvir EM is the HIV prevention medication. So what i have now is a years supply of 300 mg Tenofovir Disoproxil Fumarate WITHOUT Emtricitabine. Can i still use it for HIV prevention? Thank you for your help.
Hello and thanks for posting.
The only approved regimen for pre-exposure prophylaxis (PrEP) is tenofovir disoproxil fumarate (TDF) with emtricitabine (FTC). It's reasonable (and in accordance with World Health Organization recommendations, to substitute lamivudine (3TC) for FTC, though this has not been formally studied. Imporantly the new formulation of tenofovir, tenofovir alafenamide (TAF) is also not an approved PrEP medication, though a large clinical trial is ongoing to determine if TAF/FTC can work for PrEP.
Unfortunately for you, TDF alone is not a recommended PrEP regimen, and I would not take it alone for prevention.
