Abstract
Purpose of Review: There is considerable heterogeneity in the use of B cell depletion in women of childbearing age, likely driven at least in part by the discrepancy between the product labels and what is known about the physiology of IgG1, including breastmilk and placental transfer.
Recent Findings: We provide practical considerations on the use of this medication class in women of childbearing potential. We discuss pre-pregnancy planning including vaccinations, safety of B cell depletion during pregnancy as well as postpartum considerations including breastfeeding.
Summary: B cell depleting monoclonal antibodies have shown to be effective for pre-pregnancy and postpartum prevention of inflammatory activity in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). B cell depleting therapies are large IgG1 monoclonal antibodies which have minimal transfer across the placenta and into breastmilk. Consideration of risks and benefits of these therapies should be considered in counseling women planning pregnancy and postpartum.
