Since metronidazole (active on flagellates) did not work, the next option would be to treat for nematodes, tapeworms (are they too big for Apistos?) and flukes (that even if located elswhere, may still cause wasting). Flubendazole is in my opinion the best choice, but praziquantel or Fluke-Tabs are good alternatives too. Do you need the dosages and treatment schemes? Dionigi
