What effect could or will Fenbendazole for goats have on a human if ingested? A friend has been doing this so as to rid herself of parasites. I know this sounds rather absurd. Is there any medical evidence that this could be harmful or even fatal to a human? Could ingesting this by a human work as it does on an animal or could it cause the onset of some other condition? I am concerned about them taking this drug. I also know the container says not for human use. Again, I know this is wild but I am serious about my inquiry. Thanks
