Summary of Use during Lactation

No information is available on the use of abatacept during breastfeeding. Abatacept is a large protein molecule with a molecular weight of 92,000. Only small amounts at most would be expected to enter breastmilk. If abatacept is required by the mother, it is not a reason to discontinue breastfeeding.[1] However, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
