Numorphan has been marketed in the U.S. before .I,m not sure how long ago they quit selling it here in the U.S. They were blue tablets .I can,t remember the mg. of the tablet form of it .They later took the tablet form of it off the U.S. market and only had the liquid form of it for surgical purposes .I have a older PDR with the liquid form desqription in it. We used to call it blue morphine on the street .This was about 30 years ago.
