Summary of Use during Lactation

No information is available on the clinical use of sunitinib during breastfeeding. Because sunitinib and its metabolite are over 90% 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 110 hours, and might accumulate in the infant. The manufacturer recommends that breastfeeding be discontinued during sunitinib therapy and for at least 4 weeks after the last dose.
