Global: Study finds PrEP safe for gay, bi men

Pre-exposure prophylaxis (PrEP) with tenofovir (found in Viread, Truvada and Atripla) is safe for men who have sex with men (MSM), according to a U.S. study presented Friday, July 23, at the XVIII International AIDS Conference (IAC) in Vienna. PrEP is one of the most promising prevention tools on the immediate horizon. With PrEP, HIV-negative individuals take antiretroviral drugs to prevent becoming infected with the virus.
