Fenbendazole is absolutely active against flukes. However, not even albendazole actually paralyzes them. There is no drug that consistently keeps flukes from scattering. Dedicated flukicides attack other parts of their biology, and most are insanely dangerous. Fenbendazole is one of the best antiparasitic drugs out there, totally safe to take alongside albendazole, ivermectin, moxidectin, levamisole, nitazoxanide, diethlycarbamazine, piperazine citrate, piperazine monohydrochloride(also active against flukes, but not effective), and the tetracycline Antibiotics that ANYBODY doing parasite treatment NEEDS to be on at least one of.
