Trientine Levels and Effects while Breastfeeding
Summary of Use during Lactation
Limited information indicates that trientine is not detectable in breastmilk. The effect of trientine on breastmilk copper and zinc concentrations in milk is conflicting, but breastfed infants appear to have normal serum copper and zinc plasma levels. Based on available data, it appears that trientine is acceptable to use during breastfeeding.
Maternal Levels. Four patients received trientine for Wilson's disease in dosages of 1000, 1500 (2 patients) and 1750 mg daily. Trientine was not detectable by HPLC in the breastmilk of any of the mothers' milk samples.
Infant Levels. Relevant published information was not found as of the revision date.
Effects in Breastfed Infants
Three infants were breastfed during maternal treatment of Wilson's disease with trientine. Serum zinc and copper concentrations were normal in these infants.
Possible Effects on Lactation
Conflicting data exist on breastmilk concentrations of zinc and copper during therapy of Wilson's disease with trientine. One abstract reported that breastmilk concentrations were normal during therapy, but another abstract from the same authors reported lower milk concentrations of zinc and copper.
