Can I Take This Drug If I'm Breastfeeding?

Most healthcare providers consider insulins (including NovoLog Mix 50/50) to be safe for breastfeeding women, much safer than most oral diabetes medications. While no studies have been done to see if NovoLog Mix 50/50 passes through breast milk in humans, this is probably irrelevant. Even if it does pass through breast milk, it would be destroyed in the digestive tract of the infant.
