This is true re electronic prescriptions. It’s an awesome system that works like a charm.
However, paper prescriptions still exist and can be used in a pinch. I had a doctor write one out for me a few months ago. He did not have access to a computer but had a pad and his stamp on him.
Keep in mind that this electronic system came online a few years ago. Most doctors have issued paper prescriptions longer than electronic prescriptions.
It’s a bit dramatic to say that there is no way to get them to do it again if the need arose.
