Pregnancy outcomes following exposure to abatacept during pregnancy

Based on these data, there does not appear to be a pattern of congenital anomalies following maternal or paternal exposure to abatacept. No cases of vertebral defects, anal atresia, cardiac defects, tracheo-esophageal fistula, renal anomalies, or limb abnormalities (VACTERL) were noted. Spontaneous abortion rates were within expected range. Abatacept should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus.
