Summary of use during lactation
No information is available on the clinical use of abemaciclib during breastfeeding. Because abemaciclib and its metabolites are over 90% bound to plasma proteins, the amount in milk is likely to be low. However, the manufacturer recommends that breastfeeding be discontinued during abemaciclib therapy and for 3 weeks after the final dose.
