From the Research
It is not recommended to take Mounjaro (tirzepatide) while breastfeeding, as there is currently insufficient data on the safety of tirzepatide during lactation, and it is unknown whether the medication passes into breast milk or what effects it might have on a nursing infant 2, 3, 4, 5. The manufacturer advises against using Mounjaro during breastfeeding due to this lack of safety information.
Key Considerations
- The primary concern is the potential risk to the infant, as the effects of tirzepatide on infant development and health are not well understood.
- There is a lack of research on the safety of tirzepatide during breastfeeding, making it difficult for healthcare providers to assess potential risks.
- Alternative medications, such as metformin or insulin, have better established safety profiles during lactation and may be considered as alternatives.
Recommendations
- If you need medication to manage diabetes or weight while breastfeeding, consult with your healthcare provider about alternative options.
- Your doctor can help weigh the potential risks and benefits based on your specific health situation.
- Caution is advised when considering the use of newer medications like tirzepatide during breastfeeding, due to the lack of research on breastfeeding outcomes.
