Summary of Use during Lactation

Quinupristin and dalfopristin are relatively large molecules that are unlikely to be excreted into breastmilk in large amounts or to be absorbed orally by the breastfeeding infant.[1] However, since no information is available on the use of quinupristin and dalfopristin during breastfeeding, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
