I have been taking 80mg twicw a day for degenerative arthritis and fibromyalgia but this has stopped being effective, On a recent visit with my physician he prescribed 100 mg Nucynta every 6 hrs to be taken along with my oxycontin. After reading it seems like most people have replaced their former meds with Nucynta, not taken this medication in conjunction with other strong pain med's. Should I be concerned or discuss this with my Doc again before i have this filled?
