Animal reproductive studies have not been conducted with this long-acting sulfonylurea. Prolonged severe hypoglycemia of 4 to 10 days has been reported in neonates born to mothers receiving a sulfonylurea, particularly a long-acting sulfonylurea, at the time of delivery. There are no adequate and well controlled studies in pregnant women. Abnormal blood glucose levels during pregnancy have been associated with a higher incidence of congenital abnormalities. If diet alone is not adequate to maintain guideline recommended blood glucose levels, most experts suggest insulin as the drug of choice during pregnancy.

Chlorpropamide Breastfeeding Warnings

Use is not recommended Excreted into human milk: Yes

According to the manufacturer, an analysis of a composite of 2 samples of human breast milk obtained from 1 patient 5 hours after ingestion of a dose if 500 mg yielded a concentration of 5 mg/mL. Some experts feel this amount of drug in the breast milk is unlikely to affect a breastfed infant; however, shorter acting drugs are preferred to avoid drug accumulation. If a mother does breastfeed while on this drug, their breastfed infant's blood glucose should be monitored.
