Limited information indicates that breastfeeding need not be interrupted after a single dose of mifepristone as in a medical abortion, but a dose of 200 mg might be preferable to a 600 mg dose in nursing mothers. Breastfeeding should be avoided during long-term therapy as a cortisol receptor blocker for controlling hyperglycemia. Because of its long half-life, the manufacturer recommends pumping and discarding milk during long-term therapy and for 18 to 21 days after the last dose.
