Summary of Use during Lactation

No information is available on the use of eptinezumab during breastfeeding. Because eptinezumab is a large protein molecule with a molecular weight of about 143,000 Da, the amount in milk is likely to be very low and absorption is unlikely because it is probably destroyed in the infant's gastrointestinal tract. Waiting for at least 2 weeks postpartum to resume therapy may minimize transfer to the infant.[1]
