No information is available on the clinical use of enasidenib during breastfeeding. Because enasidenib is 98.5% bound to plasma proteins and its active metabolite is 96.6% bound to plasma proteins, the amount in milk is likely to be low. However, the half-life of enasidenib is 137 hours and it might accumulate in the infant. The manufacturer recommends that breastfeeding be discontinued during enasidenib therapy and for at least 2 months after the end of therapy.
