I was taking the same med's that you were taking for several yr's and had the same problem. My PM doc changed my med's to 90mg's of methadone for my long term dose then 15-Mg's of oxycodone 4xdaily and the BIG difference was adding Nucynta 100mg's 3x daily. The oxy's and nucynta are ordered for break thru pain but I take them on a regular schedule and so far I am finally getting the 24hr relief for now. And the future plan is to rotate about every 3-4 month's between the methadone 90-Mg's and the oxycontin 80-Mg's for the best relief..The office I have been going to has been rotating the opiates for the last year and have had very good result's.
The Nucynta is a C2 narcotic in the opiate family but works on different receptor's in the brain, unlike adding dilaudid or morphine or just increasing the dosage of oxycodone. The nucynta worked as if I had not built up a tolerance to opiates.. My tolerance to oxy's or dilaudud has become so high that increasing the mg's just doesn't work for me but the nucynta does.
