Men wanting to father a child should discontinue use and perform an accelerated elimination procedure to decrease the plasma concentration of teriflunomide to less than 0.02 mg/L. Women of childbearing potential should use effective contraception during treatment and after treatment as long as teriflunomide plasma concentration is above 0.02 mg/L. Patients should be advised if there is any delay in onset of menses or any other reason to suspect pregnancy, they must notify a physician immediately for pregnancy testing. If pregnancy is confirmed, the patient should be advised of the risk to the fetus. There is a possibility that rapidly lowering the blood level of teriflunomide, at the first delay of menses, may decrease the risk to the fetus. For women receiving teriflunomide treatment, who wish to become pregnant, the drug should be stopped and an accelerated elimination procedure is recommended in order to more rapidly reach a concentration below 0.02 mg/L. See Warnings section for further information on accelerated elimination. A teriflunomide pregnancy registry has been established. Healthcare providers are encouraged to enroll the patient in this registry if pregnancy occurs during treatment.
