The first-ever daily pill to help prevent against HIV was approved on July 16 by U.S. regulators for use in uninfected adults who are at risk for getting the virus that causes AIDS.
Truvada, made by Gilead Sciences in California, has been on the market since 2004 and was approved by the Food and Drug Administration (FDA) for a new use as a tool to help ward off HIV in otherwise healthy people, in combination with safe sex and regular testing.
Gilead Sciences Inc. has marketed Truvada since 2004 as a treatment for people who are infected with the virus.
But company studies have shown the drug can prevent people from contracting HIV when used as a precautionary measure.
