ABSTRACT

Triclabendazole was used in treatment of 249 fascioliasis patients selected from 25 provinces including 19 Northern and 6 Southern ones. Two different doses were used for two groups: 10mg/kg/body for 226 patients, and 20mg/kg/body for 43 others, twice per day with the interval 6-8 hours from meals.
