Maybe so but if you give people a tube of the stuff with instructions for a horse, and they try to take it, they are likely to overdose. Even if they try to adjust the dose, they have to do conversions and weigh it. Some people will mess up the calculations and OD. That's why the pharmacy just tells you to take 2 pills twice a day. That's not to mention the fact that the quality control of veterinary medicine is far lower and the concentration may be significantly off.
