Glipizide Pregnancy Warnings

In rat reproductive studies, mild fetotoxic effects were observed at dose levels from 5 to 50 mg/kg. This is a perinatal effect and believed to be directly related to the hypoglycemic action of the drug. No teratogenic effects were found in rats and rabbits. Neonates born to mothers receiving a sulfonylurea at the time of delivery have experienced prolonged severe hypoglycemia, especially with use of agents that have prolonged half-lives. Recent information suggests that abnormal blood glucose levels during pregnancy are associated with a higher incidence of congenital abnormalities. Sulfonylureas may not be suitable for the treatment of diabetes during pregnancy as significant metabolic changes occurring during this time make control of blood sugar difficult. There are no adequate and well-controlled studies in pregnant women.
