Is Semaglutide Safe While Breastfeeding?

What Is Semaglutide?

Semaglutide is a GLP-1 receptor agonist that supports metabolic health by:

• Enhancing insulin secretion
  
• Reducing appetite and caloric intake
  
• Slowing gastric emptying and promoting satiety
  
  

FDA-approved uses include:

• Wegovy® – for chronic weight management
  
• Ozempic® / Rybelsus® – for type 2 diabetes management
  
  

Semaglutide may support weight-related goals and glucose control under medical supervision.

What Does the Research Say About Semaglutide and Breast Milk?

Human Studies

A 2024 study analyzed breast milk samples from eight lactating women who received subcutaneous semaglutide. Using high-resolution liquid chromatography-mass spectrometry, researchers found no detectable levels of semaglutide in any samples collected at 0, 12, and 24 hours post-administration. The estimated relative infant dose (RID) was calculated at 1.26%, significantly below the 10% threshold considered acceptable for breastfeeding medications.

Animal Studies

Animal studies have shown that semaglutide can transfer into breast milk in species like rats. However, due to differences in physiology and milk composition, these findings may not directly translate to humans.

‍

Potential Risks for Nursing Infants

While current human data is reassuring, potential concerns include:

1. Hypoglycemia

Semaglutide influences insulin activity. If transferred through milk, it could potentially impact infant blood glucose levels.

2. Gastrointestinal Disturbances

In adults, semaglutide may cause nausea, vomiting, or diarrhea. Similar symptoms could occur in infants exposed through breast milk, although this is unconfirmed.

3. Reduced Milk Supply

Appetite suppression or side effects like vomiting or diarrhea may decrease maternal caloric intake or hydration, potentially influencing milk production.

Current guidance from product labels advises against using semaglutide while breastfeeding due to the lack of safety data.

Professional Guidelines on Semaglutide During Lactation

Most prescribing information, including that for Rybelsus®, advises patients to avoid semaglutide while nursing.

If you are breastfeeding and considering GLP-1 treatment, your provider may:

• Recommend delaying treatment until weaning
  
• Suggest alternative weight management strategies with more established lactation safety profiles
  
• Monitor both maternal and infant health closely if medication use is deemed necessary

Benefits of Semaglutide for Mothers (When Not Breastfeeding)

For postpartum individuals who are not breastfeeding, GLP-1 therapy may offer supportive benefits for:

• Weight regulation after pregnancy
  
• Blood sugar control for those with type 2 diabetes
  
• Cardiometabolic risk reduction in eligible populations
  

Eden’s licensed providers can help determine if treatment is appropriate once lactation ends or if other medications may be considered in the meantime.

Where to Access Semaglutide Safely

Semaglutide is a prescription-only medication available through licensed pharmacies. For safety:

• Avoid unregulated online sellers or products without prescriptions
  
• Do not use compounded semaglutide unless prescribed by a qualified provider for a medically justified reason (Eden does not offer this)
  
• Confirm that your provider and pharmacy use FDA-approved medications sourced from registered facilities

Final Thoughts

Currently, semaglutide is not recommended during breastfeeding due to limited human data. While recent studies suggest minimal transfer into breast milk, the risk to nursing infants remains unclear.

If you're considering semaglutide for weight or blood sugar management, discuss your breastfeeding status and health goals with a licensed provider. Delaying treatment or exploring safer alternatives during lactation may be advised.
