Summary of Use during Lactation

No information is available on the clinical use of regorafenib during breastfeeding. Because regorafenib is 99.5% bound to plasma proteins, the amount in milk is likely to be low. However, one of its metabolites has a half-life of up to 70 hours, and might accumulate in the infant. The manufacturer recommends that breastfeeding be discontinued during regorafenib therapy and for 2 weeks after the final dose.
