What are recommendations for lactation if you're taking Glyburide?
Limited data indicate that the levels of glyburide in milk are negligible. 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]
