We report a case of an infant with HIV receiving raltegravir granules for oral suspension and rifampicin-based TB prophylaxis. Raltegravir trough levels remained subtherapeutic and viral load increased during concurrent rifampicin therapy despite using double-dosed raltegravir. Even after rifampicin therapy, a higher dose was needed. This highlights the importance of therapeutic drug monitoring and dose adjustments of raltegravir in infants with rifampicin as comedication.
