Taking anti-HIV pill as needed prevents infection

By Andrew M. Seaman (Reuters Health) – Taking an anti-HIV pill shortly before sex and for a few days afterward can help protect people against infection with the human immunodeficiency virus, according to researchers in France and Canada. In 2012, the U.S. Food and Drug Administration approved the pill, known as Truvada, for so-called pre-exposure prophylaxis (PrEP) against HIV, the virus that causes AIDS. Uninfected individuals who take Truvada every day can cut their risk of getting HIV during sex by more than 90 percent, according to the U.S. Centers for Disease Control and Prevention (CDC).
