NovoLog and Breastfeeding
No clinical studies have been conducted on NovoLog (insulin aspart) and breastfeeding, so it is not known whether the drug passes through breast milk. However, it would be destroyed in the digestive tract (of the infant) even if it did pass through breast milk, because it is digested and inactivated when taken by mouth. Before using NovoLog, breastfeeding women should talk to their healthcare providers.
