Summary of Use during Lactation

No published information is available on the use of doravirine during breastfeeding. In the US and other countries where access to clean water and affordable replacement feeding are available, it is recommended that mothers living with HIV not breastfeed their infants to avoid postnatal transmission of HIV-1 infection. 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.[1]
