Apparently it's not as easy as it would seem.
"Pam Eaton, CEO of the Idaho Retailers Association which represents Idaho pharmacies, testified in Senate committee that without an over-the-counter label that includes information like drug interactions, Idaho pharmacies largely can't sell ivermectin over-the-counter."
Amazon sells fenben pills, so probably iver also. No scrips needed. I buy durvet iver paste from amazon and valleyvet.com
Yeah, I get the paste from Valley Vet, too. Amazon requires a prescription for Ivermectin tablets.
