Prezcobix is indicated as a complete regimen for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults and adolescents 12 years of age and older who have no history of antiretroviral therapy and no known retroviral resistance to any of its components [1]. It contains the active ingredients darunavir and cobicistat [1].
What is Genvoya used for?
Genvoya is indicated for the treatment of HIV-1 infection in adults and adolescents 12 years of age and older and weighing at least 35 kg, who have no active or historical evidence of drug resistance to any component of Genvoya [2].
