Still think it’s a wind-up.
And no other posts under his profile, yes lock it, it's stupid.
I don't think it's a wind up.
Because it's outside your realm of experience or comfort zone doesn't make it fantasy. I can feel the OP's frustration when actually seeking help and constantly coming up against a brick wall. I have encountered similar ignorance when consulting my doctor about a sheep acquired illness and actually being told to ask my vet about treatment because the doctor didn't have the knowledge and couldn't be bothered to find out!
Not all health professionals know everything

That's why I said that a well researched individual is more likely to find the answer than a poorly motivated professional.
All the information is there on the internet if you bother to spend the time and I'm sure IN is just as capable of looking it up as anyone else. He/she doesn't sound like a complete moron, so should be credited with enough commonsense not to do anything stupid.
By the way IN - I too read that the dog dose for such as Panacur is suitable for humans also. But DO get it verified by a doctor (who will have read the same article) or it is most likely have dire consequences.
