Not sure about the drug you have, but I remember a few years ago, when I was doing landscaping work, I was working for this older lady, got to talking about painkillers, she told me she had an old bottle of percocet, she was going to throw them out, but I convinced her to give them to me...this was 2008, the bottle of pills had been filled in 1996...so they were pretty damn old, at first I was worried about taking them, but decided to take 2 and see what happens, even though these pills were over 12 years old, they still worked just fine...got me feeling good, like a brand new percocet would have...I didnt notice any difference in them!
