Stribild is a four-in-one fixed-dose combination tablet used for the treatment of HIV-1 infection. It contains elvitegravir, cobicistat, emtricitabine, and tenofovir disoproxil fumarate (TDF)—four active antiretroviral agents that work together to suppress viral replication and help maintain immune health. As a complete regimen, Stribild eliminates the need for multiple separate pills, offering convenience and improved adherence for people living with HIV.
