Summary of Use during Lactation

No information is available on the clinical use of gefitinib during breastfeeding. Because gefitinib is 90% bound to plasma proteins, the amount in milk is likely to be low. However, its half-life is about 48 hours and it might accumulate in the infant. The manufacturer recommends that breastfeeding be discontinued during gefitinib therapy.
