Indinavir is no longer marketed in the US. Published experience with indinavir during breastfeeding is limited, but some infants may achieve high levels of the drug in breastmilk. Indinavir is not a recommended agent during breastfeeding.[1,2] Achieving and maintaining viral suppression with antiretroviral therapy decreases breastfeeding transmission risk to less than 1%, but not zero. Individuals with HIV who are on antiretroviral therapy with a sustained undetectable viral load and who choose to breastfeed should be supported in this decision. If a viral load is not suppressed, banked pasteurized donor milk or formula is recommended.[3,4]
