Niraparib Levels and Effects while Breastfeeding

Summary of Use during Lactation

No information is available on the clinical use of niraparib during breastfeeding. Because niraparib is 83% bound to plasma proteins, the amount in milk is likely to be low. The manufacturer recommends that breastfeeding be discontinued during niraparib therapy and for 1 month following therapy.
