Abstract:
This article reviews the use of combination emtricitabine (FTC)/tenofovir as preexposure prophylaxis (PrEP) for HIV-negative patients at high risk of acquiring HIV, including heterosexual men and women, men who have sex with men, and IV drug users. When used with classic prevention strategies such as condoms, PrEP has been found effective in reducing the risk of HIV transmission.
