Accidental High-Dose Liraglutide Exposure During Pregnancy: A Case Report

Case SeriesPreliminary evidence
The takeaway

Case report documents high-dose liraglutide exposure in a pregnant woman with obesity, providing safety data for an increasingly common clinical scenario as GLP-1 drugs are prescribed to women of reproductive age.

Pregnancy exposure documented

High-dose liraglutide exposure during pregnancy — contributing essential safety data for an increasingly common clinical scenario

What the researchers found

Case report documenting pregnancy outcome after high-dose liraglutide exposure in an obese woman, contributing to the limited safety evidence for GLP-1 drugs in pregnancy.

Why it matters

Millions of women of reproductive age take GLP-1 drugs. Accidental pregnancy exposure will occur. Every documented case adds to the safety evidence that clinicians desperately need to counsel patients.

The numbers in context

Maximum dose: 3 mg subcutaneously daily. Exposure occurred during the first trimester. Child assessment at 14 months postpartum.

How the study worked

Single case report documenting clinical course, pregnancy outcome, and maternal/fetal monitoring after high-dose liraglutide exposure during pregnancy.

Who was studied

One pregnant woman with obesity exposed to liraglutide 3 mg daily during first trimester

What this study cannot tell us

Single case report cannot establish safety. Pregnancy outcomes depend on many factors beyond drug exposure. Case reports may be biased toward unusual outcomes.

How to read the evidence

Preliminary evidence: single case report. Important for building the pregnancy safety evidence base despite limitations.

When this study was published

Published in 2025. Addresses the growing need for GLP-1 pregnancy safety data.

The bigger picture

GLP-1 drugs are not approved for use during pregnancy, and clinical trials exclude pregnant women. As prescribing expands to younger women, pregnancy registry data and case reports like this are the only source of safety information. A growing database of pregnancy outcomes will eventually inform clinical guidance.

Questions still open

  • Should pregnancy registries be mandatory for all GLP-1 drugs?
  • How long before planned pregnancy should GLP-1 drugs be discontinued?
  • Do the known "fertility boost" effects of GLP-1 weight loss increase unplanned pregnancy risk?

Common questions

What if I get pregnant while on a GLP-1 drug?
Stop the medication and contact your doctor immediately. GLP-1 drugs are not approved for pregnancy use. Current guidance recommends stopping at least 2 months before planned pregnancy. Case reports like this help build safety data, but the evidence is still very limited.
Do GLP-1 drugs increase fertility?
Yes — weight loss from GLP-1 drugs can restore ovulation in women with obesity-related infertility or PCOS. This means some women may become pregnant unexpectedly. Use reliable contraception while taking GLP-1 drugs if pregnancy is not desired.
