Medical Information
**V. INDICATIONS** **Adults** ISENTRESS is indicated in combination with other antiretroviral agents for the treatment of human immunodeficiency virus (HIV-1) infection in adult patients. This indication is based on analyses of plasma HIV-1 RNA levels in three double-blind controlled studies of ISENTRESS. Two of these studies were conducted in clinically advanced, 3-class antiretroviral (NNRTI, NRTI, PI) treatment-experienced adults through 96 weeks and one was conducted in treatment-naïve adults through 240 weeks. The use of other active agents with ISENTRESS is associated with a greater likelihood of treatment response (see VIId. Clinical Studies – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). **Pediatrics** ISENTRESS is indicated in combination with other antiretroviral agents for the treatment of HIV-1 infection in children and adolescents 2 years of age and older. This indication is based on the evaluation of safety, tolerability, pharmacokinetic parameters and efficacy of ISENTRESS through at least 24-weeks in a multi-center, open-label, noncomparative study in HIV-1 infected, treatment-experienced children and adolescents 2 to 18 years of age (see VIId. Clinical Studies – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). The safety and efficacy of ISENTRESS 400 mg tablets have not been established in children less than 6 years of age. The safety and efficacy of ISENTRESS chewable tablets have not been established in children less than 2 years of age.
**VIII. CONTRAINDICATIONS** ISENTRESS is contraindicated in patients who are hypersensitive to any component of this medicine.
