Summary of Use during Lactation

No information is available on the clinical use of vemurafenib during breastfeeding. Because vemurafenib is more than 99% bound to plasma proteins, the amount in milk is likely to be low. However, its half-life is 57 hours and it might accumulate in the infant. The manufacturer recommends that breastfeeding be discontinued during vemurafenib therapy and for 2 weeks after the final dose.
