Very Low Risk
A chelating agent that helps remove heavy metals such as copper, lead and mercury from the body. Used to treat Wilson's disease, cystinuria, severe rheumatoid arthritis and chronic active hepatitis.
It is excreted in breast milk in no or no detectable amount (Kodama 2021, Izumi 2012), and no clinical or analytical problems (Cu, Zn) have been observed in infants whose mothers took it. (Kodama 2021, Reuner 2019, Sternlieb 2000, Messner 1998, Bunke 1989, Gregory 1983)
Oral bioavailability decreases by half in the presence of food, so its passing to the infant’s plasma via ingested breast milk would be very difficult.
Copper and zinc levels in breast milk of mothers treated with penicillamine, trientine or zinc are normal according to more recent studies (Kodama 2021) and lower than normal according to older ones. (Bunke 1989)
Cases of breast hyperplasia and hyperprolactinemia have been reported in patients treated with penicillamine. (Craig 1988, Kahl 1985, Thew 1980)
