Breast milk drug levels measured to protect infants from HIV meds
NCT ID NCT05648201
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how five common HIV drugs enter breast milk in 20 healthy women who were finishing breastfeeding. The goal was to find out if the drug levels could be too high (risking infant side effects) or too low (risking drug resistance if the baby gets HIV). Participants took a single dose of one of the drugs, and researchers measured drug concentrations in blood and milk.
