Limited data indicate that the levels of glipizide in milk are low. However, an alternate drug for which there is more information may be preferred, especially while nursing a newborn or preterm infant. Monitor breastfed infants for signs of hypoglycemia such as jitteriness, excessive sleepiness, poor feeding, seizures cyanosis, apnea, or hypothermia. If there is concern, monitoring of the breastfed infant's blood glucose is advisable during maternal therapy with hypoglycemic agents.[1,2]
Drug Levels
Two women who had delivered via cesarean section and were receiving glipizide 5 mg daily in the immediate postoperative period had milk glipizide levels measured. Trough glipizide milk levels were undetectable (<80 mcg/L). The authors estimated that the maximum dosages that a fully breastfed infant would receive is <27% of the weight-adjusted maternal dosage.[3]
Effects in Breastfed Infants
Blood glucose levels were normal in 2 breastfed infants whose mothers were taking oral glipizide 5 mg daily.[3]
