Truvada, the HIV prevention drug approved by US health regulators. The opinion of the Food and Drug Administration is that Truvada can be used by persons at high risk of disease and anyone who may hold in sexual activity with HIV-infected partners. There have been concerns the circulation of such a drug could engender a false sense of security. Present have also been worries that a drug-resistant strain of HIV could expand.
Studies since 2010 showed that Truvada reduced the risk of HIV in healthy gay men and among HIV-negative heterosexual partners of HIV-positive people by between 44% and 73%. A number of health workers and groups active in the HIV society opposed a green light for the once-daily pill. Truvada, made by California-based Gilead Sciences, is previously backed by the FDA to be in use with existing anti-retroviral drugs for people who contain HIV.
