They don't really expire per say, they just may not be as "strong" as if they were new. Does that make sense? They should be fine to still give though. I've given Tyson older meds as well for his ears with no problems.
Agree with [MENTION=13133]TyTysmom[/MENTION], I've used very old mess before with success. But if you do not have 10 days worth it probably won't cure the UTI. Hopefully you caught it early!
I agree, I have used some old meds. and they seem to work just fine! I hate to waste stuff, and I just saw a doctor on TV talking about the same thing, and he says just because it has an expiration date does not mean it is no good. He actually said it keeps for years. If pills are crumbled to bits, then they are too old [MENTION=8541]Daphnee[/MENTION]
Kind of what I've been reading... antibiotics are 1-3 yrs shelf life(1-3right?!?!?).. as long as stored safely, it just looses potency.. if not stored correctly, can get bacteria and other bad stuff.. Just a little wigged out about the stinky smell, not real bad, kinda what you'd expect from an antibiotic, but still stinky... A refill is just $4 so, trying for that without a vet visit... Thanks..
