Cetuximab Levels and Effects while Breastfeeding

Summary of Use during Lactation

No information is available on the clinical use of cetuximab during breastfeeding. Because cetuximab is a large protein molecule with a molecular weight of 145,782 Da, the amount in milk is likely to be very low. It is also likely to be partially destroyed in the infant's gastrointestinal tract and absorption by the infant is probably minimal. Until more data become available, cetuximab should be used with caution during breastfeeding, especially while nursing a newborn or preterm infant. The manufacturer recommends that breastfeeding be discontinued during cetuximab therapy and for 2 months after the last dose.
