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."
Just order from other states where it is legal... and have it mailed to you. Easier.
When Idaho catches on that it is losing sales to mail order from other states... things will change.
It is legal in Idaho now.
