Oxymorphone
"I'm happy to read so many others who have been helped by this medication.  I've been taking it for over a year now, each time my pain doctor increases it a bit (I'm now taking 50 mg in the morning and 50 mg at night).  Unfortunately, I really don't notice that much pain relief from this medication.   I take Norco for "breakthrough pain" and it seems as though I need to take that 4 times a day along with this for relief of my back pain."
