  • Darunavir (tradename Prezista in Europe, developed as TMC-114) is a protease inhibitor that needs to be boosted (by 14 times) with another drug – either ritonavir or cobicistat.
  • Dose. Different doses are currently recommended if darunavir is being used in your first combination or if you have used HIV treatment before.
    If this is your first treatment the standard dose is 1 x 800 mg tablets plus either 100 mg ritonavir or 150 mg cobicistat, once daily.
    For people who have used HIV treatment before: 1 x 600 mg tablet plus 100 mg ritonavir, both twice-daily.
  • Darunavir needs to be taken with food. Even with ritonavir boosting, food is needed to boost these levels by another 30%. The type of food is not important according to the EU patient information.
  • Side effects: nausea, rash, diarrhoea, lipodystrophy and lipid changes.
  • Other notes: when compared to Kaletra, darunavir had lower rates of nausea, diarrhoea and lipid changes.This is a sulfa-containing drug, and should be used with caution in by people with a known sulfa allergy.
  • Darunavir plus cobicistat are coformuated in a single pill call Prezcobix.
