Upon discontinuing teriflunomide and based on the teratogenicity risk, it is recommended that all women of child-bearing potential undergo the accelerated elimination procedure, which includes verification of teriflunomide plasma concentrations less than 0.02 mg/L (0.02 mcg/mL). Human plasma concentrations of teriflunomide less than 0.02 mg/L (0.02 mcg/mL) are expected to pose minimal risk. Without an accelerated elimination procedure, it takes teriflunomide on average of 8 months (and up to 2 y) to reach plasma concentrations less than 0.02 mg/L.
