Executive Summary
only injectable forms of semaglutide are recommended during breastfeeding 12 Feb 2026—The FDA prescribing information states plainly that there areno data on the presence of semaglutide in human milk, the effects on the breastfed
The question of can I use semaglutide while breastfeeding is a complex one, with evolving research and varying expert opinions. For mothers seeking to manage conditions like type 2 diabetes or navigate postpartum weight loss, understanding the current recommendations and available data is crucial for making informed decisions about their health and the well-being of their infants. While semaglutide itself is a widely recognized medication, its use during breastfeeding requires careful consideration due to limited long-term safety data.
Currently, the prevailing advice from medical professionals and manufacturers leans towards caution. For oral semaglutide, such as the brand Rybelsus®, it is generally not recommended while breastfeeding. This is largely due to the presence of an absorption enhancer, salcaprozate sodium, which is known to pass into breast milk. The prescribing information for Rybelsus® explicitly states that women who are breastfeeding not use the tablet form of the medication. Similarly, Ozempic and Wegovy, which are injectable forms of semaglutide, carry recommendations for avoidance during breastfeeding. Some guidance suggests that it's advisable to stop Ozempic at least 2 months before getting pregnant or starting to breastfeed.
However, the landscape for injectable semaglutide is slightly more nuanced. Some studies, including those investigating subcutaneous semaglutide during breastfeeding, have yielded promising initial findings. A significant study in 2024 reported no detectable levels of semaglutide in breast milk, suggesting minimal transfer and potentially a lower risk to breastfed infants. These findings align with the idea that semaglutide appears to be safe during lactation due to minimal transmission into breastmilk. Despite these encouraging results, the consensus remains that more extensive research is needed to definitively establish the safety profile for prolonged use. As such, only injectable forms of semaglutide should be used during breastfeeding, and even then, with a thorough discussion with a healthcare provider.
The primary concerns surrounding semaglutide use during lactation revolve around two main areas: potential drug transfer into breast milk and the impact of maternal weight loss on milk production. While current research indicates minimal transfer of semaglutide into human milk, the possibility of semaglutide entering breast milk and potentially causing side effects in infants, such as decreased appetite, cannot be entirely ruled out. Furthermore, rapid maternal weight loss, which can be a goal for some using semaglutide, can negatively impact milk supply and maternal nutrition, which are vital for both the mother and the nursing infant. Therefore, rapid weight loss can impact milk production and maternal nutrition.
The absence of conclusive long-term data means that for many, the recommendation is to wait or explore safer alternatives while breastfeeding. The Breastfeeding Network in the UK, for instance, advises that GLP-1 medications, including semaglutide, should not be taken while breastfeeding due to insufficient safety data. This cautious approach is rooted in the principle of prioritizing infant well-being when definitive evidence of safety is lacking. The FDA prescribing information also highlights that there are no data on the presence of semaglutide in human milk, reinforcing the need for a conservative stance.
In summary, while there is emerging research suggesting that semaglutide is unlikely to enter breast milk in significant amounts, the overall recommendation for mothers using semaglutide (Ozempic®/Wegovy®) during breastfeeding is generally not recommended. The manufacturer advises against use during breastfeeding for oral forms, and even for injectables, the advice leans towards caution and further investigation. It is not recommended to take semaglutide while you are breastfeeding, and a healthcare provider should always be consulted to discuss individual risks and benefits, as well as potential alternatives. The focus remains on ensuring the health of both the lactating mother and the breastfed child, and until more comprehensive data is available, a prudent approach is essential.
