Can You Breastfeed While Taking Mounjaro?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Mounjaro (tirzepatide) is not recommended during breastfeeding due to insufficient safety data. The FDA has not established whether tirzepatide passes into breast milk or affects nursing infants. Clinical trials specifically excluded pregnant and breastfeeding women, leaving a critical knowledge gap about potential risks. Animal studies showed tirzepatide was present in milk, though human data remains limited. Most healthcare providers recommend discontinuing Mounjaro while breastfeeding and exploring alternative weight management approaches. Consult your healthcare provider about safer weight loss options if you're nursing.
