Oxycontin Er Or Cr?
WHATS THE DIFFERENCE BETWEEN OXYCONTIN ER AND CR?
I TAKE ER AND MY NEW INSURANCE COVERS CR; WHATS THE DIFFERENCE BETWEEN ER AND CR?
This is a little tricky; my understanding is that oxycodone ER/CR stand for extended and controlled release.
Oxycodone ER is slowly released over 12 hours allowing a consistent flow of the painkiller to your tissues and more consistent pain relief.
Controlled release oxycodone (CR) is also slowly released over 12 hours to provide a consistent dose of the pain killer. They both appear to be essentially the same thing.
Oxycontin, on the other hand, is the controlled release form of oxycodone; it's simply a new name for it. If you're taking oxycontin you're taking extended or controlled release of oxycodone.
As far as I'm able to tell all three drugs are the same. Health Central, for instance, lists all of them under 'oxycontin'.
You have to be careful not to chew any of these. Because they were developed to be released over a long period of time they contain higher than normal levels of the painkiller. Thus if you chew them and take in all the pain killer at once you can actually overdose on them (!).
