Scabies

I kind of need a nurses help asap. I got scabies from a worker and need ivermectin but insurance won't pay for it. The creams didn't work and the nurse told I could get the animal version here http://amzn.to/1gTvHbn

I read online that's what others have done but I don't know how much to take and how often. It shows weight by horse.
