Answer by Dr. Ru: About Benznidazole usage in lactation

Antiprotozoan drug used for the treatment of American Trypanosomiasis (Trypanosoma cruzi) or Chagas Disease (see specific info). It is excreted into breast milk in small amounts and there have not been observed problems in infants from treated mothers (Garcia-Bournissen 2015, Vela-Bahena 2015). Benznidazole has been very well tolerated when administered directly to infants and newborns (Altcheh 2011, Chippaux 2013).

Answer by DrLact: About Benznidazole usage in lactation

Benznidazole is excreted into milk in dosages much lower than the treatment dosage for infants. Because of the low levels of benznidazole in breastmilk and safety when given directly to infants, its use is acceptable in nursing mothers.

Median infant age Ten women with chronic Chagas disease received benznidazole in a median oral dose of 5.65 mg/kg twice daily for 30 days. Median infant age was 5.2 months (range 20 days-13 months). Five children were exclusively breastfed and the others partially breastfed. None of the infants had any adverse reactions attributable to benznidazole.[4] A postpartum woman diagnosed with Chagas disease was treated with benznidazole 5 mg/kg daily beginning one month postpartum and continuing for 30 days. She continued to breastfeed (extent not stated) her infant. The authors reported that no adverse effects were seen in the infant.[6]
