Pregnancy outcome in women exposed to leflunomide before or during pregnancy

Abstract

These data provide additional reassurance to women who inadvertently become pregnant while taking leflunomide and who undergo the washout procedure, as well as women who discontinue the medication prior to conception but have no prepregnancy documentation of drug clearance. However, until more conclusive data become available, women receiving leflunomide should be advised to use contraceptive methods and avoid pregnancy.
