Today, a nurse from nursery called me as a baby's mother ask her if she can breastfed her baby while she's on insulin daily doses. I looked up at LactMed and found the profile of Insulin
No specific information exists on the newer biosynthetic insulins (i.e., aspart, detemir, glargine glulisine, lispro) during breastfeeding. In general, mothers with diabetes using insulin may nurse their infants. No adverse reactions have been reported due to insulin in breastmilk. In fact, insulin in breastmilk may decrease the risk of type 1 diabetes in breastfed infants.[1][2]
