Semaglutide and Pregnancy: What You Need to Know
If you’re on semaglutide and thinking about getting pregnant — or if you’ve just found out you’re pregnant — this is important.
The FDA’s Position
The FDA classifies semaglutide as pregnancy risk category — use is not recommended. The prescribing information for both Ozempic and Wegovy states:
“Discontinue Wegovy in patients at least 2 months before a planned pregnancy.”
This applies to all semaglutide products: Ozempic, Wegovy, and Rybelsus. It also applies to tirzepatide (Mounjaro, Zepbound) — Eli Lilly recommends stopping at least 2 months before trying to conceive.
Why 2 Months?
Semaglutide has a long half-life — about 1 week. After your last injection, the drug takes approximately 5 half-lives (5 weeks) to be essentially cleared from your system. The 2-month recommendation provides a safety margin beyond that.
What the Research Shows
Animal studies showed problems. In rats and rabbits, semaglutide at doses relevant to human use caused:
- Embryo loss (early pregnancy loss)
- Structural abnormalities
- Reduced fetal growth
Human data is limited but growing. A 2024 analysis published in JAMA Network Open of pregnancy outcomes among women exposed to GLP-1 medications found no statistically significant increase in major birth defects compared to the general population. However, the study authors emphasized that the sample size was too small to draw definitive conclusions, and the data was observational.
The honest assessment: We don’t have enough human pregnancy data to know semaglutide is safe during pregnancy. The animal data gives reason for caution. The medical consensus is: don’t take the risk.
What to Do If You’re Planning to Get Pregnant
Timeline:
- Talk to your doctor about your pregnancy plans
- Begin tapering off semaglutide (don’t stop cold turkey)
- Stop semaglutide at least 2 months before trying to conceive
- Use reliable contraception during the taper and the 2-month washout period
- Your doctor may switch you to a pregnancy-safe weight management plan
Weight management during the washout: See our guide on how to stop semaglutide without gaining weight. The habits you build now carry you through pregnancy and beyond.
What If You Got Pregnant While on Semaglutide
Don’t panic. Here’s what to do:
- Stop semaglutide immediately. Don’t take your next dose.
- Contact your OB/GYN right away. Let them know what medication you were on, your last dose date, and your dose level.
- Don’t assume the worst. The limited human data doesn’t show a clear pattern of harm. Many pregnancies exposed to semaglutide in early weeks have resulted in healthy births.
- Your doctor may recommend additional monitoring — more frequent ultrasounds and standard prenatal screening.
The Fertility Angle
Here’s something interesting: weight loss from semaglutide can actually improve fertility. Obesity is a significant cause of ovulatory dysfunction and reduced fertility. Women who lose weight before conceiving often have:
- More regular menstrual cycles
- Improved ovulation
- Better IVF outcomes
- Lower risk of gestational diabetes and preeclampsia
The “Ozempic baby” phenomenon is real — many women report unexpected pregnancies after starting GLP-1 medications, likely because weight loss restored ovulatory function they didn’t know was impaired. If you’re on semaglutide and not trying to get pregnant, use reliable contraception.
Breastfeeding
There’s no data on semaglutide in human breast milk. The prescribing information says the decision to breastfeed while on semaglutide should consider the benefit to the mother vs. potential risk to the infant. Most doctors recommend against GLP-1 use while breastfeeding.
For Partners
Semaglutide doesn’t appear to affect male fertility. Studies in male rats showed no impact on sperm quality or reproductive function at therapeutic doses. Men do not need to stop semaglutide before their partner tries to conceive.
The Bottom Line
Semaglutide and pregnancy don’t mix — stop at least 2 months before trying to conceive. If you discover you’re pregnant while on it, stop immediately and call your doctor, but don’t catastrophize. The weight loss benefit can actually improve your fertility and pregnancy outcomes if you plan the timing right.
