Since the last update we have not found published data on its excretion in breastmilk.
Being a polypeptide of 153 amino acids with a large molecular weight, it is very unlikely to pass into breast milk.
Its low oral bioavailability makes it difficult for it to pass to the infant’s plasma via ingested breast milk as, due to its protein nature, it degrades in the gastrointestinal tract and is not absorbed.
No problems have been observed in infants of mothers treated with anakinra. (Duman 2019, Smith 2018, Youngstein 2017, Chang 2014, Berger 2009)
