Semaglutide & Breastfeeding

[Meganj]

As of 2025, is there anymore research on semaglutide while breastfeeding? I have a 3 month old who pretty much only breastfeeds at night if she wakes up, or sometimes a snack during the day. I’d say she’s 99% formula fed.

Recent studies—including one published in 2024 show that only minuscule amounts of semaglutide enter breast milk. So far, no harmful effects have been reported in breastfed infants.

The main concern with GLP-1 medications (like semaglutide) and infants under 12 months isn't the medicine itself in the milk—it's the possibility that these medications might lower milk supply or change the nutritional content of your breast milk.

Since your baby is almost entirely formula-fed, with only occasional breastfeeding, there’s very little risk to your baby if you start or continue using semaglutide.
