Abatacept and breast feeding
No information is available on the use of abatacept during breastfeeding. Abatacept is a large genetically engineered fusion protein that interferes with T-cell activation. It has a molecular weight of 92,000. Only small amounts would be expected to enter breastmilk. If abatacept is required by the mother, it is not a reason to discontinue breastfeeding. However, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
