No information is available on the clinical use of afatinib during breastfeeding. Because afatinib is about 95% bound to plasma proteins, the amount in milk is likely to be low. However, its half-life is about 37 hours and it might accumulate in the infant. the manufacturer recommends that breastfeeding be discontinued during afatinib therapy and for 2 weeks after the last dose.
