Is Metformin Safe During Pregnancy?

Metformin is generally considered safe during pregnancy for women with type 2 diabetes or gestational diabetes. The American College of Obstetricians and Gynecologists supports its use when blood sugar control is needed. Studies involving over 3,000 pregnant women show no increased risk of birth defects compared to insulin. Metformin crosses the placenta but doesn't appear to harm fetal development. Many doctors prefer it over other diabetes medications because it reduces the risk of excessive weight gain and preeclampsia. However, some women may need to switch to insulin if metformin alone doesn't adequately control blood sugar levels.
