how long does oxycontin 40 mg last

it's time released at 12 hours, but reports vary, some who are very tolerant of opiods report pain relief for 8 hours, sometimes people get the full 12. every one is different, depends on tolerance.

I would re-evaluate with your doc the amount of Oxy that you're taking.It is a 12hr formulation, that might not mean that you are getting 12 hours of coverage, which i doubt you are since you take so much more B/T meds. I know that from personal experience that the tolerance I build up really doesnt' effect the actual AMOUNT of drug i take, but how long it lasts.  Generally i only get a couple hours of good pain mgmt from 20mg hydrocodone, but i've been taking that for a while now... Also are you taking anything non-narcotic to supplement them...tylenol or advil.....Ultram is another excellent adjunct (even tho people don't think it works....it does) to a narcotic pain mgmt program. It is a very weak opioid, but works very well (at least for me) in conjuntion with other stonger medicines.....Best of luck
