I found an old bottle of pills while cleaning at my aunts. The bottle is stained badly, but we could make out the pharmacy. The pharmacy it came from has been closed now for almost 2 years. I asked my aunt and she said that she has never seen them. I looked them up and believe they could be a pain med. called percacet, but the site had no pictures. The meds. are oblong, blue, waxy and say 1 6 0 and oc on the other side. I would like to know what they are for sure and if possible what is the shelf life. My family does not take much med. but we would keep them for emergency if we could varify. -Thanks in advance.
