FDA approves second drug to prevent HIV infection
January 2020—The FDA approved Descovy (emtricitabine 200 mg and tenofovir alafenamide 25 mg) in at-risk adults and adolescents weighing at least 35 kg (approximately 77 lbs.) for HIV-1 pre-exposure prophylaxis to reduce the risk of HIV-1 infection from sex, excluding those who have receptive vaginal sex. (Descovy is not indicated in individuals at risk of HIV-1 infection from receptive vaginal sex, the company reports, because the effectiveness in this population has not been evaluated.)
