Breastfeeding moms: new study checks drug levels in milk

NCT ID NCT06867835

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This completed study tested 10 healthy breastfeeding women to see how much of the drug Vyleesi (bremelanotide) passes into breast milk after a single injection. Participants pumped and stored milk before dosing and stopped breastfeeding for the study. Researchers measured drug levels in milk and blood over 24 hours. The goal is to understand if the drug could reach the baby through milk.

What this could lead to

If results show little drug passes into milk, it may help guide safe use of Vyleesi in breastfeeding mothers.
