Inadvertent exposure to GLP-1 receptor agonists during pregnancy does not appear to pose a significant teratogenic risk, with congenital abnormality rates in exposed pregnancies being lower than or comparable to placebo groups.

If you took a GLP-1 medication (like Ozempic or Wegovy) before knowing you were pregnant, current data from clinical trials does not show an increased risk of birth defects compared to women who did not take these medications. You should stop the medication as soon as you know you are pregnant and consult your doctor for standard prenatal care.

Why this rating

Data is aggregated from regulatory clinical trials but limited by small sample sizes of unplanned pregnancies and lack of long-term follow-up for many cases.
