  • Make a rough estimate of how many people you aim to treat in a year. If you do not have data on the epidemiology and distribution of fascioliasis in your country, you can make a reasonable estimate by contacting the major hospitals and asking them how many cases they see per year.
  • Calculate how many tablets you need in a year, based on the ratio: one 250mg for 25kg of body weight (e.g. three tablets for a man weighing 75kg).

Triclabendazole for paragonimiasis

Since 2010 triclabendazole is also donated for treating human paragonimiasis. If you need drugs to treat individuals infected with paragonimus spp. Please follow the same application process as above.

The recommended treatment regimen for paragonimiasis is triclabendazole, 20 mg/kg of body weight, in two divided doses of 10 mg/kg of body weight, to be administered on the same day.

In communities and villages where cases of paragonimiasis appear to be significantly clustered, universal treatment (MDA) should also be considered. In this case, the recommended treatment regimen would be triclabendazole, 20 mg/kg of body weight in a single administration.
