A praziquantel-ineffective fascioliasis case successfully treated with triclabendazole.

Human fascioliasis cases in Japan have been reported infrequently and the most appropriate therapy for this disease remains to be determined. This case report describes a patient with the infection unsuccessfully treated with multiple high doses of praziquantel for over 1 year and eventually cured by the administration of triclabendazole in two single doses of 10 mg/kg and 12.5 mg/kg 5 months apart.
