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.
In the US, prescriptions with refills have a label on the bottle indicating how many refills left. I imagine in a recognized crisis, you would be able to get those refilled with little trouble, maybe even if it said zero refills as long as it was a drug typically used long term and not a drug commonly abused.
We don't do that. You just get a box and that's it.
