To avoid some of these issues I try to stock up in advance.
But 1) doctors forcing you to wait til your sick to give you an Rx for antibiotic. You can’t have it on hand.
2) insurance will only pay for 30 days at a time
BUREAUCRACY KILLS YOU.
Some pharmacies won't refill until you've consumed at least 75 percent of the previous fill. I don't know how common that is or why they refuse, but a few months ago I drove my neighbor to the pharmacy because she couldn't afford a second ride in a cab after the pharmacist told her to come back in a few days. (That would have added about $20 to the cost of the medicine.)
So...if you’re a prepper who needs medication to survive, don’t bother to pack for 60 days if you can’t go 30 without the meds!
