Entrectinib Levels and Effects while Breastfeeding
Summary of Use during Lactation
No information is available on the clinical use of entrectinib during breastfeeding. Because entrectinib and its active metabolite are >99% bound to plasma proteins, the amount in milk is likely to be low. However, because of its potential toxicity in the breastfed infant, the manufacturer recommends that breastfeeding be discontinued during entrectinib therapy and for 7 days after the last dose.
