No information is available on the clinical use of lenvatinib during breastfeeding. Because lenvatinib is more than 98% bound to plasma proteins, the amount in milk is likely to be low. However, its half-life is about 28 hours and it might accumulate in the infant. The manufacturer recommends that breastfeeding be discontinued during lenvatinib therapy and for at least 1 week after the last dose.
