Risk Summary: Animal studies from the start of organogenesis through delivery did not show a potential for adverse developmental outcomes at maternal systemic exposures 27 times the exposure in human patients at the recommended dose. IgG is known to cross the placental barrier and was detected in fetal plasma in animal studies; therefore, this drug has the potential to be transmitted from the mother to the developing fetus.

Comments:
-Adequate methods of contraception should be encouraged.
-Verify negative pregnancy status in females of reproductive potential prior to initiating therapy.
-If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential harm to the fetus.
-Advise females of reproductive potential to use effective contraception during therapy and for 3 months after.
