Can I Take Saxenda (Liraglutide) While Pregnant?

Is Liraglutide Safe to Take During Pregnancy?

If you are pregnant and currently taking liraglutide (sold as Saxenda for weight loss or Victoza for type 2 diabetes), the short answer is: stop taking it and call your doctor today. Liraglutide is not recommended during pregnancy. Animal studies have shown it can harm fetal development, and there is not enough human data to say it is safe. This is not a wait-and-see situation.

The FDA has flagged liraglutide with reproductive toxicity warnings based on studies in rats and rabbits. Those studies found reduced fetal weight and skeletal malformations at doses comparable to human therapeutic levels. Because no large-scale human trials exist for obvious ethical reasons, the full scope of risk in people cannot be precisely measured, but the standard medical position is firm: stop liraglutide before or immediately upon discovering pregnancy.

What Do the Studies Actually Show?

The evidence base here has two very different tiers, and it is worth understanding both.

Animal data is the stronger signal. In controlled reproductive toxicity studies, liraglutide caused:

• Embryo-fetal toxicity in rats and rabbits, including reduced fetal growth
• Skeletal abnormalities at doses that are clinically relevant to human use
• Increased early pregnancy loss in some animal models

Human data is far more limited. Pregnancy registries maintained by the drug's manufacturer collect spontaneous reports, but the numbers are too small to draw statistically reliable conclusions. There are no randomized controlled trials involving pregnant people, and the observational data that exists cannot rule out harm.

The takeaway: absence of proof is not proof of absence. The precautionary stance exists because the animal findings are meaningful and human data cannot yet override them.

Why Do Some Women Encounter This Question Mid-Pregnancy?

This situation is more common than many people expect. Saxenda is prescribed for long-term weight management, a condition that does not pause when someone becomes pregnant. Victoza is used for type 2 diabetes, which can coexist with pregnancy. And roughly half of all pregnancies in the United States are unplanned, which means medication reviews often happen after conception, not before.

If you found out you were pregnant while actively taking liraglutide, you are not alone, and acting quickly now still matters. The goal is to minimize continued exposure and get your care plan adjusted right away.

What Should You Do If You're Already Pregnant?

Do not wait for your next scheduled appointment. Contact your OB-GYN or prescribing doctor the same day you confirm the pregnancy. Here is what to expect from that conversation:

• Stop liraglutide immediately. Your provider will confirm this and may want to document when you last took it and how long you have been on it.
• If you were using it for diabetes, your doctor will transition you to insulin or another pregnancy-compatible blood sugar regimen. This handoff needs to happen quickly because uncontrolled blood sugar in pregnancy carries serious risks of its own.
• If you were using it for weight management, weight loss is not a goal during pregnancy. Your care team will shift focus to healthy gestational weight gain instead.
• Tell your provider how far along you are. Exposure timing matters for clinical documentation and monitoring decisions.

Do not attempt to substitute liraglutide with an over-the-counter appetite suppressant or herbal supplement. None of those are approved or safe during pregnancy either.

Comparing Diabetes Management Options During Pregnancy

For women who were taking liraglutide to manage type 2 diabetes, stopping without a replacement plan is not acceptable. Blood sugar control is critical throughout pregnancy. Here is how common approaches compare:

The table reflects current general guidance, not a personal prescription. Your provider will choose a regimen based on your specific situation, how far along you are, and how well your blood sugar is controlled.

Why the Risks of Doing Nothing Are Also Real

Stopping liraglutide without a plan is not a safe alternative to continuing it. Obesity and diabetes during pregnancy both carry significant risks that require active management:

• Obesity in pregnancy raises the likelihood of gestational diabetes (high blood sugar that develops during pregnancy), preeclampsia (a dangerous blood pressure condition), cesarean delivery, and fetal macrosomia (a larger-than-normal baby with delivery complications).
• Uncontrolled blood sugar in diabetic pregnancies is associated with congenital abnormalities (birth defects that form early in development), increased risk of stillbirth, and neonatal hypoglycemia (dangerously low blood sugar in the newborn after delivery).

This is why the message is not just "stop liraglutide" but "stop liraglutide and replace it with something appropriate, today." For high-risk pregnancies, co-management with a maternal-fetal medicine specialist or endocrinologist is often recommended alongside standard OB care.

Frequently Asked Questions

What happens if I accidentally took Saxenda in early pregnancy?

Contact your OB or prescribing doctor the same day, not at your next scheduled visit. One accidental dose is unlikely to cause definite harm, but your provider needs to document exposure duration and monitor the pregnancy appropriately going forward.

Can liraglutide cause miscarriage or birth defects?

Animal studies showed skeletal abnormalities and reduced fetal growth at clinically relevant doses. Human data is too limited to confirm or rule out these risks, which is why most guidelines recommend stopping liraglutide before or immediately upon learning you are pregnant.

Is Ozempic or Wegovy safer than Saxenda during pregnancy?

No. Semaglutide (Ozempic, Wegovy) belongs to the same GLP-1 drug class as liraglutide and carries similar pregnancy warnings. None of these medications are considered safe during pregnancy, and all should be discontinued upon confirmed conception.

Can I restart liraglutide after giving birth or while breastfeeding?

Talk to your doctor before restarting. It is unknown whether liraglutide passes into breast milk in meaningful amounts. Most clinicians recommend waiting until breastfeeding is fully discontinued before resuming any GLP-1 weight loss medication.

What weight loss options are safe for overweight pregnant women?

No weight loss medications are approved during pregnancy. Instead, your care team will guide you toward appropriate gestational weight gain using ACOG guidelines, along with registered dietitian counseling and supervised, low-impact physical activity suited to your trimester.

The Bottom Line

Liraglutide (Saxenda) is a clear stop-now situation during pregnancy, with no gray area. Animal studies show fetal harm, human safety data is very limited, and no weight management medication is approved for use in pregnancy. If you discover you are pregnant while taking liraglutide, contact your OB or prescribing doctor the same day to stop the medication and arrange a safe alternative plan, especially if you were using it to manage diabetes.
