Is Exenatide safe while breastfeeding?

Here is what LactMed, the Drugs and Lactation Database published by the U.S. National Institute of Child Health and Human Development (NICHD), reports about Exenatide. The text below is quoted from that source — it is not our own verdict.

Summary of use during breastfeeding

No information is available on the clinical use of exenatide during breastfeeding. Because exenatide is a large peptide molecule with a molecular weight of 4187 daltons, the amount in milk is likely to be very low and absorption is unlikely because it is probably partially destroyed in the infant’s gastrointestinal tract. It has a short half-life, which might make it a better choice among drugs in this class for nursing mothers. If exenatide is required by the mother, it is not a reason to discontinue breastfeeding. However, until more data become available, exenatide should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. Some experts recommend closely monitoring of infant growth and developmental milestones and the nutritional status of the lactating woman.[1]

Alternatives LactMed lists

“No published information” means the studies do not exist yet — not that Exenatide is known to be harmful, and not that it is known to be safe. Your prescriber or pharmacist can weigh your baby's age and whether a better-studied alternative would do the same job. Worth asking before stopping a medicine you need.
