What is this medication?

EMTRICITABINE; TENOFOVIR ALAFENAMIDE (em trye SYE ta been; ten OF oh vir AL a FEN a mide) helps manage the symptoms of HIV infection. It may also be used for PrEP (pre-exposure prophylaxis), which lowers the risk of getting HIV through sex. It works by limiting the spread of HIV in the body. It is a combination of two antiretroviral medications. This medication is not a cure for HIV or AIDS and it may still be possible to spread HIV to others while taking it. It does not prevent other sexually transmitted infections (STIs).

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.
