Is glyburide/metformin safe in pregnancy?

glyburide/metformin has not shown any drug associated risks for major birth defects, miscarriage, or adverse maternal outcomes from a small number of published studies and postmarketing experience with glyburide/metformin use in pregnancy over decades. However, sulfonylureas (including glipizide) cross the placenta and have been associated with neonatal adverse reactions such as hypoglycemia. Therefore, glyburide/metformin should be discontinued at least two weeks before expected delivery.
