q12 hours is really somewhat of a gimmick......especially in a younger persons with quicker metabolism.....yes you should spread it out as close to q8 hours as possible.

Even the 40mg didn't last me 12 hours. That's why my doc was kind enough to do it 3 x/day. With breakthru meds on hand to boot.
Pain comes with a vengeance.
Also, we develop our own individual levels of tolerance, which also should be kept into consideration

After doctors visit and I told him of my side affects swetty, itchy and I forgot the other, he then switched me to ms contin 30mg three times a day. I am getting so forgetful, I have to write it down to remember it. I started it today and slept another 8 hours after sleeping all night. We will see how this works. Thanks for the info.

As I just posted. Oxy contin was designed poorly. The active drug, oxy codone has a 3-4 hour hald life. The pill make is such that is releases half the medication immediately and then the other half in 6 hours. So from 4-6 hours you pain returns with a vengence and then at 6 hours you get the other half. This fact makes it very hard to dose it effectively.Three times a day is better but not perfect. I think ms contin is far superior as the pill substrate is waxy and the release is much more even and smooth. You just need a week or to to get used to the morphine floatiness, but it DOES go away. Of course talk it over with you doctor before changing anything as you ALWAYS should. You will dial it in, be patient, I KNOW it's HARD.But fast large dose and med changes with pain drugs tend to give uncertain and ineffective results. Maybe ms contin with percocet10/325's for break though pain. They also make instant release oxy. Good luck...be patient Brian

The Ms contin has not even touched my pain. I did not realize I was in such pain until on this drug. The other was helping but my pain had been intensifying and I did not realize it and that is why my old meds were not covering it. Now it is on to Dialudid 4 every 4 hours to see if it helps. Then i will be changed to jurnista the extended release. Morphine has not ever helped I did not think about that before trying the Ms contin. Thanks everyone will see how this goes.
