No information is available on the clinical use of duvelisib during breastfeeding. Because duvelisib is 98% bound to plasma proteins, the amount in milk is likely to be low. However, because of its potential toxicity in the breastfed infant, the manufacturer recommends that breastfeeding be discontinued during duvelisib therapy and for at least 1 month after the last dose.
