WHAT IS PREZCOBIX®?
  • PREZCOBIX® is a prescription HIV-1 (Human Immunodeficiency Virus 1) medicine used with other antiretroviral medicines to treat HIV-1 infection in adults. HIV is the virus that causes AIDS (Acquired Immune Deficiency Syndrome). PREZCOBIX® contains the prescription medicines PREZISTA® (darunavir) and TYBOST® (cobicistat).
  • It is not known if PREZCOBIX® is safe and effective in children under 18 years of age.
  • When used with other antiretroviral medicines to treat HIV-1 infection, PREZCOBIX® may help:
    • reduce the amount of HIV-1 in your blood. This is called “viral load.”
    • increase the number of CD4+ (T) cells in your blood that help fight off other infections.
  • PREZCOBIX® is always taken in combination with other HIV medications for the treatment of HIV-1 infection in adults. PREZCOBIX® should be taken once daily with food.
  • PREZCOBIX® does not cure HIV-1 infection or AIDS, and you may still experience illnesses associated with HIV-1 infection. You must keep taking HIV-1 medicines to control HIV-1 infection and decrease HIV-related illnesses.
  • Ask your healthcare provider if you have any questions on how to prevent passing HIV to other people.
  • Please read the Important Safety Information below and talk to your healthcare provider to learn if PREZCOBIX® is right for you.
