Somewhere I saw that a cheaper way to obtain fenbendazole was the Safe-Guard suspension for goats. But it says "not for human use." The other ingredients are
Water
Methyloparaben
propylparaben
silicon dioxide
providones
trisodium citrate ihydrate
carboxymethycellulose sodium
citric acid monohydrate
Anything there to be worried about (I know that WC Fields warned about water causing rust inside)?
