Is Mounjaro or Zepbound Safe During Pregnancy? pregnancy safety guide image

Short answer

Mounjaro and Zepbound contain tirzepatide. Do not start, stop, or continue tirzepatide in pregnancy without the clinician managing your diabetes, weight, or fertility plan.

Prescriber-guided only

What is the safest way to think about this?

MotherToBaby notes that weight loss is not recommended during pregnancy and that human studies have not been done to determine whether tirzepatide increases several pregnancy-related risks. The practical answer is not a blanket panic response; it is a prompt medication-plan conversation.

What is generally okay?

  • Contact the prescriber and pregnancy clinician promptly if you use tirzepatide and are pregnant or trying to conceive.
  • Ask how to manage blood sugar, weight-related care, nausea, nutrition, and medication changes safely.
  • Tell your clinician the brand, dose, last injection date, reason for use, and any other diabetes or weight-loss medicines.

What should you avoid or double-check?

  • Avoid using tirzepatide for weight loss during pregnancy.
  • Avoid stopping diabetes treatment without a replacement plan.
  • Avoid relying on social-media GLP-1 pregnancy anecdotes instead of a clinician-led risk-benefit review.
