Just heard an NPR report that said the majority of pharmaceuticals have no appreciable expiration date; a DOD study for their (huge) drug stockpile found the effective expiration date was >10years. The very short expiration date (there are often 2 dates on the bottle) are automatic 1 year pharmacy expiration dating mandated by state law, largely from nonscientific Pharma lobbying.
The Mfg expiration dating is based on elevated temperature and humidity study of opened drugs and even then the drug degrades less than 10%, actual storage conditions are never approximated unless you store your meds open in your sauna. The estimated cost is hundreds of millions of dollars yearly to consumers who discard active drugs (and poison the landfills but that's another issue!). The NPR report states "To date, though, the FDA has no reports of adverse events related to outdated drugs." NONE!

Its like drugs from Canada; no science to support the fear which has great financial benefit to the big companies.
