How PREZCOBIX® can help

Once-Daily PREZCOBIX® is two medications in one pill and is taken in combination with other HIV medications for the treatment of HIV-1 infection in adults. It contains 800 mg of darunavir and 150 mg of cobicistat. PREZCOBIX® may help you reach an undetectable* viral load.

PREZCOBIX® can help:
  • Support immune function by lowering how much HIV is in your blood (also called viral load)
  • Increase the number of cells that fight infections in the body (your CD4+/T-cell count)

Prezcobix® Has a High Genetic Barrier to Resistance

PREZCOBIX® is a treatment option with a high genetic barrier against resistance, that might be right for you. Ask your healthcare provider about PREZCOBIX® and your risk for developing drug resistance

A medication with a high genetic barrier against resistance can help keep the virus undetectable,* even if the HIV has changed. Developing drug resistance can potentially cause treatment failure and limit future treatment options.


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.

Stop taking PREZCOBIX® and call your healthcare provider right away if you develop any skin changes with symptoms such as fever, tiredness, muscle or joint pain, blisters or skin lesions, mouth sores or ulcers, red or inflamed eyes like “pink eye” (conjunctivitis).

PREZCOBIX® may cause liver problems. Some people taking PREZCOBIX® may develop liver problems which may be life-threatening. Signs and symptoms of liver problems include dark (tea-colored) urine, yellowing of your skin or whites of your eyes, pale-colored stools (bowel movements), nausea, vomiting, pain or tenderness on your right side below your ribs, or loss of appetite. Tell your healthcare provider if you develop any of these symptoms.

* Undetectable was defined as a viral load of <50 copies/mL of the virus in your blood.
