I keep older bottles of meds that didn't work because of side effects but that I'd take in a pinch if needed. I have a pretty healthy selection from which to choose and keep them locked up in case of apocalyptic type events keeping me from getting meds when I need them. I'm paranoid about something like this happening and tend to have a stockpile of stuff on hand just in case.

I'm really sorry you are in this situation and I hope you get this sorted.
