Didn't know that. When did that change ? ; on the medicines for my horses it still says words like Buscopan (also good for humans).
For me they deserve their money. My veterinarian is something like 1.55 m (something around 5 feet I think) and very skinny. She spends her days with her arms up horses and cows, giving injections to horses who are much larger than her and who aren't in a good mood... Quite a hazardous occupation from time to time.
Maybe it's just the Uk ?.
I've heard that some vets get animal drugs via the grey market from places like Greece, which are significantly cheaper ?
