COMMENTS
CLEAR WORMER Granules is a pet wormer brand from BOB MARTIN containing generic fenbendazole. It is a generic version of PANACUR C.
Fenbendazole is a veteran benzimidazole introduced in the 1970s (by HOECHST). It is a broad-spectrum anthelmintic effective against most gastrointestinal worms that infect pets, including roundworms (Toxocara canis, Toxocara cati, Toxascaris leonina), hookworms (Ancylostoma spp, Uncinaria stenocephala) and whipworms (Trichuris vulpis), but also against lungworms (Aelurostrongylus abstrusus) and certain tapeworms (e.g. Taenia spp). It is abundantly used in livestock and horses, moderately in pets. It is not used in agriculture.
Fenbendazole and most other benzimidazoles (e.g. febantel, albendazole, mebendazole, etc.) and tetrahydropyrimidines (e.g. pyrantel, morantel, etc.) have no residual effect, i.e. they act against the worms during a few hours after administration but are quickly metabolized and excreted. For this reason treatment must often be repeated for certain indications. This is in contrast with wormers containing macrocyclic lactones (e.g. milbemycin oxime, selamectin) that ensure protection against numerous roundworms during weeks after a single treatment.
