Usage:

Fenbendazole (Hoechst brand names Panacur and Safe-Guard, Intervet Panacur and Panacur Rabbit) is a broad spectrum benzimidazole anthelmintic used against gastrointestinal parasites including roundworms, hookworms, whipworms, the taenia species of tapeworms, pinworms, aelurostrongylus, paragonimiasis, strongyles and strongyloides and Fenbendazole can be administered to sheep, cattle, horses, fish, dogs, cats, rabbits and seals. Drug interactions may occur if using bromsalan flukicides such as dibromsalan and tribromsalan. Fenbendazole abortions in cattle and death in sheep have been reported after using these medications together.

Fenbendazole is poorly absorbed from the gastrointestinal tract in most species. The LD50 in laboratory animals exceeds 10 g/kg when administered orally

Package and Storage:

Fenbendazole is packed in 25kg fiber drum with shelf life 5 years.
