  • Indinavir (tradename Crixivan in Europe) is a protease inhibitor that was generally used with a boosting dose of ritonavir. Indinavir is now rarely used in any country.
  • Standard adult dose: 2 x 400 mg capsules, twice daily. Each dose taken with a separate 100 mg dose of ritonavir. Other doses have been studied.
  • Side effects: crystals in the urine, kidney stones, hair loss, dry skin, ingrowing toe nails, frozen shoulder, yellow eyes and skin (jaundice), changes in lipids (blood fat) which should be routinely monitored, lipodystrophy (fat accumulation) and diarrhoea.
  • Other notes: this drug is now rarely used because alternative newer drugs have much fewer side effects. Do not take with atazanavir.
