Eflornithine Levels and Effects while Breastfeeding

Summary of Use during Lactation

Maternal intravenous eflornithine 400 mg/kg daily for 7 days did not cause any adverse serious effects in breastfed infants. After topical application, eflornithine is poorly absorbed so it is not likely to reach the bloodstream of the infant or cause any adverse effects in breastfed infants.

A cohort of 33 infants who were breastfed (extent not stated) by hospitalized mothers taking nifurtimox was followed in the Democratic Republic of the Congo. Thirty mothers took a full course of 30 doses of oral nifurtimox 15 mg/kg daily and all received 14 doses of intravenous eflornithine 400 mg/kg daily for 7 days for human African trypanosomiasis. (sleeping sickness). Nursing mothers also took a median of 4 other concomitant medications, including amoxicillin, ciprofloxacin, metronidazole, trimethoprim-sulfamethoxazole, aspirin, and diclofenac (1 patient each); hydrocortisone, promethazine and quinine (2 patients each); levamisole (6 patients); sulfadoxine-pyrimethamine (8 patients); dipyrone (13 patients); acetaminophen (16 patients); and mebendazole (17 patients).
