One issue here which is obvious to me is that access to insulin should not be gated on paperwork. I can walk into any pharmacy in Canada and say "I'm diabetic and need insulin" and the pharmacist will sell it to me. They'll ask questions of course since this is not the usual path but my doctor's office being open will have no influence on whether I get it -- just on whether it's a 5 minute process or a 15 minute process, and potentially whether I have to pay myself or have it covered by insurance.

Is that true for every type and format? You can walk into walmart and get regular and NPH insulin over the counter, no questions asked. Newer ones require a Rx.

I do think that the US is obnoxiously conservative, and far more medications should be OTC.

Instead, you cant even buy kidney friendly cat food without an expensive Rx from a vet and tons of controls. Heaven forbit someone buy it without proper consultation. Think of the Kittens!
