The labels say 1 or 2 years, but the actual shelf life is more like 10 or 20. They would give a 3 year shelf life to sodium chloride, despite the fact sea salt has been around for billions of years unchanged. Ok, except for the occasional neutrino absorption or proton decay...

For most drugs, using them beyond their expiration dates would probably have a negligible loss of pharmcological activity depending how old they are and their storage conditions. You don't want a cavalier attitude with expired tetracycline, or you may get Fanconi’s syndrome. I wouldn't be surprized if there are other drugs with expiration dates that need to be respected.
