CVS review: Pharmacy refused to fill my prescription

I had Ivermectin and I have had it before Lyme disease. The doctor office put down Covid prevention which is the same thing. First they lied said CvS does not fill Ivermectin then they tried to say it was the ‘board' wouldn't let them. Then finally the pharmacist said he was denying it because he didn't think it worked! I said you are going between me and my doctor? He was a total arrogant jerk. He is a total liar because another pharmacy filled no problem.
