Can Horses eat Fenbendazole for cattle?

I doubt it as horses may get colic from eating cattle feed

*Fenbendazole is used in the Panacur powerpacks. If you use it correctly, then your horse will be fine with it. Roundworms release a toxin that kills horses as they die off, so you need to watch your horse for worm colic as you use it and follow a simple schedule. Every horse is different, but I use the cheaper cattle brand for my standardbred and appaloosa for about 4 days 2 times a year.
