"i was recently changed from oxycontin 20mg er x2 twice a day with 5mg oxycodone three times daily for breakthrough pain.  that combination did nothing for me.  i am now on nucynta er 150 mg twice per day with opana 10mg 3 per day for breath through pain.  to me i find myself using my breakthrough medication more than i did with the oxycontin.  i have only been on the nucynta for a week now and i am hoping that the relief will get better the longer i am on it."
