Sacituzumab govitecan Breastfeeding Warnings

Breastfeeding is not recommended during use of this drug and for 1 month after the last dose.

Excreted into human milk: Unknown
Excreted into animal milk: Data not available

Comments:
-No information is available on the clinical use of this drug during breastfeeding.
-The effects in the nursing infant are unknown; there is the potential for serious adverse reactions in a breastfed child.

Because sacituzumab is a large protein molecule, the amount in milk is likely to be very low. It is also likely to be partially destroyed in the infant's gastrointestinal tract; absorption by the infant is probably minimal. Govitecan is a small-molecule anticancer drug that may enter milk and be absorbed by the infant.
