Dacomitinib Levels and Effects while Breastfeeding

Summary of Use during Lactation

No information is available on the clinical use of dacomitinib during breastfeeding. Because dacomitinib is 98% bound to plasma proteins, the amount in milk is likely to be low. However, because of its potential toxicity in the breastfed infant and its half-life of 70 hours, the manufacturer recommends that breastfeeding be discontinued during dacomitinib therapy and for at least 17 days after the last dose.
