Penicillamine Levels and Effects while Breastfeeding

Summary of Use during Lactation

Limited information indicates that penicillamine is not detectable in breastmilk. Copper and zinc levels in breastmilk are reduced in mothers receiving penicillamine.[1][2][3][4][5] Penicillamine has been used with apparent safety during nursing of 3 infants. In infants who breastfeed infrequently, taking the drug right after nursing and waiting 4 to 6 hours before nursing again should minimize the amount of penicillamine in breastmilk. Copper and zinc levels in breastmilk are reduced in patients taking penicillamine. The implications for infants of this effect are not known.

Drug Levels

Maternal Levels. Four patients received penicillamine for Wilson's disease in dosages of 800, 600 (2 patients) and 500 mg daily. Penicillamine was not detectable by HPLC in the breastmilk of any of the mothers' milk samples.[4]

Infant Levels. Relevant published information was not found as of the revision date.

Effects in Breastfed Infants

One woman taking penicillamine 1500 mg daily for cysteinuria breastfed her infant for 3 months with no apparent adverse effects in her infant.[6]

Another woman breastfed 2 infants after 2 pregnancies while being treated for Wilson's disease with penicilliamine 750 mg daily. One infant had prolonged icterus that was unlikely to have been related to the penicillamine.[7]

Possible Effects on Lactation

Milk concentrations of zinc and copper are reduced during therapy of Wilson's disease with penicillamine.[3][7][8][9]
