The discussion in another thread has gotten me curious. Here in Ontario, I can walk into my nearest 24-hour pharmacy and buy any insulin over the counter (no prescription) as long as I'm willing to pay cash. For it to be covered by insurance, a prescription is needed. I know it's the same in Germany. So what's up in the good old U.S. of A.? Do you need a prescription to get insulin under all circumstances? And if not, then under what circumstances can you get it over the counter?
