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...

I am not a MD!, However anything except-live culture antibiotics should be good to go, the expiration date is a tool to limit liability in most cases

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.
