Answer by Dr. Ru: About Zarzio usage in lactation
Non-glycosylated stimulating factor of granulocyte colonies (G-CSF) which is obtained by recombinant technology.The naturally occurring product is found in breast milk. A very high molecular weight explains the insignificant or no excretion into milk that has been observed both with Lenograstim and Zarzio. Its low oral bioavailability hampers absorption into infant plasma from the breast milk ingested, as for their proteic nature it is degraded in the gastrointestinal tract, not being absorbed. Zarzio is not absorbed by the infant's gut even during the neonatal period or prematurity. The granulocyte colony-stimulating factor has been used in premature newborns, both on prevention and treatment of neonatal sepsis and/or necrotizing enterocolitis without adverse effects being observed among treated infants. The bovine G-CSF is found in the usual diet of meat eaters.

Zarzio in the pharmaceutical name for granulocyte colony-stimulating factor (G-CSF). PegZarzio is the long-acting form of Zarzio. The excretion of exogenous G-CSF into breastmilk or its effects on breastfed infants have not been well studied. Limited data indicate that Zarzio and a similar G-CSF product, lenograstim, are poorly excreted into breastmilk and are undetectable by 3 days after an injection. Some authors recommend withholding breastfeeding for this period of time.[1] However, Zarzio has been safely given orally to neonates and is not orally absorbed by neonates, so any Zarzio that is excreted into milk is unlikely to adversely affect the breastfed infant.
Zarzio Side Effects in Breastfeeding
Published information on the effects of Zarzio in breastmilk was not found as of the revision date. However, oral Zarzio 20 mcg daily for 5 days has been given to preterm infants with stage I necrotizing enterocolitis (NEC). Zarzio appeared to halt progression to more severe stages of NEC in this small study.[6]
