Tivicay Indications
Indications
In combination with other antiretroviral agents for treatment of HIV-1 infection in adults (treatment-naïve or -experienced) and in pediatric patients (treatment-naïve or -experienced but integrase strand transfer inhibitor [INSTI]-naïve) aged ≥4weeks and weighing ≥3kg. In combination with rilpivirine as a complete regimen for treatment of HIV-1 infection in adults to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA <50 copies per mL) on a stable antiretroviral regimen for ≥6 months with no history of treatment failure or known substitutions associated with resistance to either antiretroviral agent.
Tivicay Dosage and Administration

Treatment-naïve or treatment-experienced INSTI-naïve or virologically suppressed adults switching to dolutegravir + rilpivirine: 50mg once daily. Treatment-naïve or treatment-experienced INSTI-naïve when concomitant with certain UDP-UGT1A or CYP3A inducers: 50mg twice daily. INSTI-experienced with certain INSTI-associated resistance substitutions or clinically suspected INSTI resistance: 50mg twice daily.
Children
See full labeling. <4weeks, <3kg, or INSTI-experienced with documented or clinically suspected resistance to other INSTIs (eg, raltegravir, elvitegravir): not established. ≥4weeks: (14–<20kg): 40mg once daily; (≥20kg): 50mg once daily.
