Emtricitabine/tenofovir, sold under the brand name Truvada among others, is a medication used to treat and prevent HIV/AIDS. It is a fixed-dose combination of two antiretroviral medications: tenofovir disoproxil and emtricitabine. For treatment, it is used either alone or together with other antiretroviral medications. For prevention before exposure, in those who are at high risk, it is recommended with safe sex practices. It does not cure HIV/AIDS. Emtricitabine/tenofovir is taken by mouth.
