What is this medication?
PREZCOBIX (Darunavir/Cobicistat) is indicated for treatment of HIV-1 Infection.
The National Institutes of Health’s COVID-19 guidelines recommend against the use of HIV protease inhibitors, such as darunavir and cobicistat for the treatment of COVID-19.
How does this medication work?
PREZCOBIX (Darunavir/Cobicistat) is a two-drug combination of darunavir and cobicistat. Darunavir binds to HIV-1 protease and inhibits cleavage of viral Gag-Pol polyprotein precursors into individual functional proteins required for infectious HIV. This results in the formation of immature, non-infectious viral particles. Cobicistat is a cytochrome P450 3A inhibitor which will increase the systemic concentration of darunavir.
How should I take this medication?
Oral: Take one tablet (darunavir 800mg/cobicistat 150mg) once daily on combination with other antiretrovirals.
Note: Genotype testing is advised prior to therapy initiation in antiretroviral treatment-experienced patients; if testing is not feasible, use is recommended in protease-inhibitor naïve patients only.
Do not use darunavir/cobicistat in combination with abacavir and lamivudine in patients with a pre-antiretroviral therapy HIV RNA ≥100,000 copies/mL.
How to Take: Take with food.
What should I watch for while using this medication?
