Others - Pregnancy & Lactation Pregnancy Category B. Adequate and well controlled studies with Adalimumab have not been conducted in pregnant women. Adalimumab is an IgG1 monoclonal antibody and IgG1 is actively transferred across the placenta during the third trimester of pregnancy. Limited data from published literature indicate that Adalimumab is present in low levels in human milk and is not likely to be absorbed by a breastfed infant. However, no data is available on the absorption of Adalimumab from breast milk in newborn or preterm infants. Caution should be exercised when Adalimumab is administered to a nursing woman.
