If you’re taking semaglutide and are planning to get pregnant—or find out you are pregnant while taking the medication—it’s completely natural to have questions about what to do next.
The short answer: semaglutide is not recommended during pregnancy. But understanding why, and knowing what steps to take, can help you feel more confident and prepared.
What is semaglutide?
Semaglutide is the active ingredient in several prescription medications used for chronic weight management and blood sugar control, including Ozempic® and Wegovy®. It belongs in a class of drugs called GLP-1 receptor agonists, which work by regulating appetite, slowing digestion, and supporting metabolic balance. When paired with healthy nutrition and regular movement, semaglutide has shown significant results in clinical trials for weight loss.
Why semaglutide isn’t recommended during pregnancy
Pregnancy is a time when your body has increased nutritional demands to support fetal growth, which is why intentional weight loss is generally not advised during this period. Semaglutide’s appetite-reducing effects work against these needs.
Beyond that, human safety data for semaglutide use in pregnancy is limited. Animal studies have raised concerns, showing associations with fetal growth issues, structural abnormalities, and pregnancy loss at certain doses.
Until well-controlled human studies exist, the U.S. FDA advises against using semaglutide during pregnancy.
If you’re planning to get pregnant while on semaglutide
Because semaglutide has a long half-life, it can remain in your system for weeks after your last dose. Here’s what to keep in mind as you plan ahead:
- Give yourself enough lead time. Most sources recommend at least a two-month washout period before trying to conceive. At Shed, we recommend three months before attempting pregnancy, which has been affirmed by multiple OB GYN specialists we have spoken with.
- Don’t stop semaglutide without talking to your provider first. They can help you build a safe and gradual transition plan.
- Prioritize sustainable habits. Going off a GLP-1 is a big shift. Building a strong foundation of nutrition and lifestyle practices before pregnancy is an important part of the process.
What if you get pregnant while taking semaglutide?
This happens more often than most people expect. While semaglutide doesn’t directly affect fertility, the metabolic improvements that come with weight loss can sometimes lead to unexpected pregnancies. It’s also worth knowing that side effects like vomiting and diarrhea can reduce the effectiveness of oral contraceptives, which is why many OB-GYNs recommend backup contraception when starting semaglutide or after a dose increase.
If you find out you’re pregnant while taking semaglutide, stop the medication and reach out to your healthcare provider right away. They will help you determine the safest path forward for you and your baby.
Starting semaglutide after pregnancy
Once your pregnancy is complete and you’ve finished breastfeeding, semaglutide may be an option again—but timing is important here, too.
Semaglutide is not recommended while breastfeeding, as it’s currently unclear whether the medication passes into breastmilk or how it might affect a nursing infant. When you’re ready to revisit treatment, your provider can help you evaluate the right timing based on your individual circumstances.
In summary
Semaglutide and pregnancy don’t mix well given what we currently know—and don’t yet know. The limited research available is why medical guidance recommends avoiding it during pregnancy, as well as the period leading up to pregnancy and while breastfeeding. If you’re considering starting or growing a family while on semaglutide, the most important step you can take is to have an open conversation with your healthcare provider.
FAQs: Semaglutide and pregnancy
What should I do if I took semaglutide before knowing I was pregnant?
Stop the medication and contact your provider as soon as possible. Early exposure doesn’t automatically indicate harm, but your provider may want to monitor you more closely as a precaution.
Is weight loss safe during pregnancy?
Intentional weight loss is generally not recommended during pregnancy. The priority should be on nourishing your body and your developing baby with adequate nutrition and energy.
Can I switch to another GLP-1 while pregnant?
No. Other GLP-1 medications follow similar guidance and are not recommended during pregnancy.
Are other GLP-1 medications safe to use during pregnancy?
No. The guidance applies broadly across GLP-1 medications. None are currently recommended for use during pregnancy.
Does semaglutide affect fertility in men?
Research in this area is limited, and there’s no definitive guidance requiring men to stop semaglutide when trying to conceive. As always, it’s worth discussing with your doctor before making any changes.
