Answer by Dr. Ru: About Nifurtimox usage in lactation

Used for treatment of Leishmania infection and American Trypanosomiasis (T. cruzi: Chagas Disease, -see specific info) and African (Trypanosomiasis T. gambiensis: Sleeping Sickness). It is excreted into breastmilk in small amounts (Garcia-Bournissen 2010) and there have not been observed problems in infants from treated mothers (Schmid 2012), so many experts consider it compatible with breastfeeding (Sankale 1991 Barennes 2010). Nifurtimox has been very well tolerated when administered directly to infants and newborns (Schmid 2012)

Answer by DrLact: About Nifurtimox usage in lactation

Limited information indicates that maternal doses of nifurtimox up to 15 mg/kg daily produce do not cause any adverse serious effects in breastfed infants. Breastmilk levels and a computer simulation found that the dose that an exclusively breastfed infant would receive through breastmilk would be much less than the dose given to treat Chagas disease in newborn infants. Other authors consider that breastfeeding is not contraindicated during the use of nifurtimox.[1][2]
