Answer by Dr. Ru: About MK-4214 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 MK-4214. 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. MK-4214 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.

MK-4214 in the pharmaceutical name for granulocyte colony-stimulating factor (G-CSF). PegMK-4214 is the long-acting form of MK-4214. The excretion of exogenous G-CSF into breastmilk or its effects on breastfed infants have not been well studied. Limited data indicate that MK-4214 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, MK-4214 has been safely given orally to neonates and is not orally absorbed by neonates, so any MK-4214 that is excreted into milk is unlikely to adversely affect the breastfed infant.
MK-4214 Side Effects in Breastfeeding
Published information on the effects of MK-4214 in breastmilk was not found as of the revision date. However, oral MK-4214 20 mcg daily for 5 days has been given to preterm infants with stage I necrotizing enterocolitis (NEC). MK-4214 appeared to halt progression to more severe stages of NEC in this small study.[6]
