Is darvocet poision after being expired for 3 years?

i would call the pharmacy and ask just out of curiousity. some meds become less potent. some become more potent after time. i was wondering the same thing about my phentermine the dr gave me for weight loss. but they are about 6yrs old and im terrified to try one!

No it doesnt turn into poison but it definantly might not work anymore and i do advise you to trash them they are only good for 2 yrs. and thats if its stayed in a cool place like a cabinet. Heat can ruin medication.
