No information is available on the clinical use of ibrutinib during breastfeeding. Because ibrutinib is more than 97% bound to plasma proteins, the amount in milk is likely to be low. The manufacturer recommends that breastfeeding be discontinued during ibrutinib therapy and for 1 week after the last dose.
