Baloxavir Levels and Effects while Breastfeeding

Summary of Use during Lactation

No information is available on the use of baloxavir marboxil during breastfeeding. Because baloxavir is 93% bound to plasma proteins, the amount in milk is likely to be low. However, because no information is available on the use of baloxavir breastfeeding, an alternate drug may be preferred, especially while nursing a newborn or preterm infant.
