What is Darunavir Used For?

Darunavir is used in the treatment of human immunodeficiency virus (HIV) infections in adult patients. Each tablet contains 600mg of darunavir, an inhibitor of the HIV protease. This prevents viral replication by binding to the enzyme’s active site, preventing the formation of mature virus particles.


Take 600 mg of darunavir (1 tablet) with 100 mg of ritonavir twice daily and with food. Your dose may vary if you are a treatment-experienced adult patient.

  • Without darunavir resistance-associated substitutions: Take 800 mg of darunavir with 100 mg of ritonavir once daily and with food.
  • With at least 1 darunavir resistance-associated substitution: Take 600 mg of darunavir (1 Daruvir tablet) with 100mg of ritonavir twice daily and with food.

If you are a treatment-experienced adult patient who is unable to undergo genotypic testing, take darunavir (600 mg) and ritonavir (100 mg) twice daily. Your doctor will determine the best treatment plan for you. Do not change your dose without talking to your doctor.


If you are allergic to darunavir, do not take this medication. Do not use it with other drugs that depend on CYP3A enzyme for clearance.
