Prescription Expiration Dates

I've posted on this before, albeit some time ago. Many people assume the expiration dates on prescription medication should be followed verbatim. That's not exactly true as this article in Back Door Survival points out:

"... with that thought, the Shelf Life Extension Program (SLEP) was developed.  The SLEP tested over a hundred drugs in their possession and found that the vast majority were 100% potent 2 to 12 years beyond their listed expiration dates."

So when the big one hits and you can't get refills for important prescription drugs, you can still use the old ones.
