Humulin N and Breastfeeding

Before taking Humulin N, breastfeeding women should talk to their healthcare providers about the benefits and potential risks. It is not known if the insulin passes through breast milk, but it would likely be destroyed in the digestive tract of the infant even if it does pass through the milk (since Humulin N is a protein that is digested and inactivated when taken by mouth).

 

An Overview of Humulin N and Breastfeeding

Although it is not clear if Humulin® N (NPH insulin) passes through breast milk, it is not expected to cause problems when used during breastfeeding. Most healthcare providers consider Humulin N to be safe for breastfeeding women and their infants, much safer than most oral diabetes medications (at least as far as breastfeeding is concerned). You should talk with your healthcare provider before taking Humulin N if you are breastfeeding or plan to start.
 

Can I Take Humulin N While Breastfeeding?

There is conflicting information available about whether or not insulin passes through breast milk. However, even if it does pass through breast milk, it would be destroyed in the digestive tract of the infant. Insulin (including Humulin N) is a protein that is digested and inactivated when taken by mouth. This is why insulin cannot be taken by mouth.
