Clinical trials for Truvada are over and the results from the study are eye popping. According to the results of the trial, a pill taken before, and after sexual intercourse can reduce the risk of HIV infection by 86 percent.
Truvada can be taken up to one day before a sexual encounter, and up to two days after and remain effective.
New Method of Using Truvada
Truvada originally received FDA approval in 2012 as a preventative measure for HIV taken as a once per day regimen. It was never tested as a one-off method of protection until now.
The technique, called pre-exposure prophylaxis (PrEP), is gaining traction within the scientific community as an alternative approach to preventing HIV transmission.
The study, conducted by French National HIV research agency ANRS, included 400 participants who were considered high risks for contracting HIV.
One group took a placebo, while the other took Truvada, two to 24 hours before sex, and 24 to 48 hours afterward.
The study “provides the first evidence that an event-driven regimen is effective among high-risk MSM (men who have sex with men) with frequent sex,” said Jonathan Mermin, director of the US Centers for Disease Control and Prevention’s National Center for HIV/AIDS.
