E37. The Ozempic Question: GLP-1s, Breastfeeding, and the Appetite Your Milk Actually Needs
Can you take Ozempic, Wegovy, Mounjaro, or Zepbound while breastfeeding? It is one of the fastest-growing questions in lactation care, and most parents are getting a shrug instead of an answer. In this episode, Dr. Ashley Robinson, IBCLC, breaks down what GLP-1 medications actually are, what the newest human milk studies found about semaglutide and tirzepatide transfer into breast milk, and why the real breastfeeding concern is not the drug in your milk but the appetite it takes away from you. She covers timing, milk supply, protein and hydration, the birth control interaction nobody mentions, compounded versions, and how to talk to your provider without shame. Evidence-based, judgment-free, and very honest about what we still do not know.
