Third-Line Antiretroviral Therapy: What Do We Do When the Appropriate Formulations Are Not Available?

Abstract

Children on antiretroviral therapy have limited options, particularly if they are failing therapy and live in resource-poor settings. We describe three cases where children accessed third-line antiretroviral therapy off-label, or used them extemporaneously with successful outcomes. We then review the evidence for performing this measure. There is an urgent need for appropriate formulations to treat young children who require a third-line or salvage regimen.
