Due to the shortage of Nucynta, my doctor changed me to MS Contin ER 15mg twice a day. I had been taking Nucynta for almost 5 years and my dose for the last few years has been 150mg of Nucynta ER twice a day. Until a couple months ago, I also received 50mg of regular Nucynta per day. Is this dose of MS Contin ER going to be enough to help my pain like the Nucynta did?
