Summary of Use during Lactation

No information is available on the clinical use of bosutinib during breastfeeding. Because bosutinib is 96% bound to plasma proteins, the amount in milk is likely to be low. However, its half-life is about 22 hours and it might accumulate in the infant. National Comprehensive Cancer Network guidelines recommend avoiding breastfeeding during bosutinib therapy and the manufacturer recommends withholding breastfeeding until 2 weeks following the last dose.[1]
