I have some pills that my pharmacy gave me some pills they are suppose to be generic percocet but they don't have 512 on the back. They have IP and 203 under that. On the back it has a line going down the back.

What did you want to know that you haven't already told us?

If you believe that the drug store gave you the wrong pills, take them back and have them check them against their stock.

You should be asking this to your pharmacy, not some strangers on the internet. The 512 brand is made by a company called mallinkrodt, the others may be a different manufacturer, call your pharmacy.

I have deleted at least one post that went on to ID the pill. It has been long discussed that for safety of our readers we do not ID pills on here.
