GLP-1 Medications and Pregnancy: What You Need to Know
This is a safety topic, not a scare. If you are pregnant, planning to be, or could become pregnant, here is what to know about GLP-1 medications, plainly.
The short answer
GLP-1 medications such as semaglutide and tirzepatide are not used during pregnancy. The general guidance is to stop a GLP-1 before trying to conceive, and to use reliable contraception while on treatment if you could become pregnant. If you are pregnant or think you might be, contact your physician promptly. This is standard caution, not a reason to panic.
Why GLP-1s are not used in pregnancy
There is not enough safety data to support GLP-1 use during pregnancy, and animal studies raised concerns, so the medications are not recommended for use while pregnant. Pregnancy is also not a time for active weight loss. The responsible default is to stop the medication and focus on a healthy pregnancy with your obstetric care.

GLP-1 medications are generally not recommended while breastfeeding either, again because of limited safety data. If you are nursing or planning to, tell your physician so your plan fits your situation. When in doubt, ask before starting or restarting.
Frequently asked questions
Can I take a GLP-1 while pregnant?
No. GLP-1 medications such as semaglutide and tirzepatide are not used during pregnancy, because there is not enough safety data and pregnancy is not a time for active weight loss. If you are pregnant or think you might be while on a GLP-1, contact your physician promptly. This is standard caution, and your physician will guide what to do next.
How long before trying to conceive should I stop a GLP-1?
Guidance commonly suggests stopping a GLP-1 a set period before trying to conceive, often around two months, but the exact timing is an individual medical decision your physician makes with you based on the specific medication and your situation. Tell your physician your family-planning plans so the timing is coordinated.
Do I need contraception while on a GLP-1?
If you could become pregnant and are not trying to, reliable contraception is recommended while on a GLP-1, because the medications are not used in pregnancy. Discuss your contraception with your physician, especially since some GLP-1 medications can affect how other oral medications are absorbed. This is part of a proper medical screening.
Is it safe to breastfeed on a GLP-1?
GLP-1 medications are generally not recommended while breastfeeding, again because of limited safety data. If you are nursing or planning to, tell your physician so your weight-loss plan fits your situation and timing. When in doubt, ask before starting or restarting the medication.
What if I became pregnant while taking a GLP-1?
Contact your physician promptly; they will advise stopping the medication and coordinate with your obstetric care. An unplanned exposure is a reason to talk to your doctor, not to panic. Going forward, a supervised program helps you plan timing safely around family planning.
