I have been on the same dose of this medication (except for the 3mos that I refused to take it late last year) for about 9 of over 11yrs with RSD/CRPS.
I've been taking it for almost 12 days now and I became more constipated as I had that under a decent control before and also became sick to my stomach throwing up for 2 days not knowing if it is the new formula or if I just got some kind of bug?
I'm on 40mgs and have stayed on the brand name after trying the generic about two years ago and not finding it to be as effective with my doctors agreeing.
I don't know if I just got a bug as far as literally being ill to my stomach or if this is a new side effect that others are experiencing?
I know I wasn't able to go to the bathroom for over 6 days and only after getting sick to my stomach and taking Phenegren (sp?) hours later was I able to go.
Because of this I haven't been able to take all my medications for pain or the Percocet for breakthrough pain like I need to which has only increased my pain levels so I don't think it works less but the new formula may be something that our bodies need to adjust to.
I'm extremely sensitive to any opiate pain medications being allergic to all I've tried except Oxycontin. You name it, I've been severely allergic to it.
Has anyone else experienced any negative side effects from the new formulation of Oxycontin? If so, what have they been?
I've never abused my medications and even take less when I can.
I appreciate any advice or others who have experienced changes since taking this.

I have been on oxycontin for several years and I just started taking the new formula recently. I have gotten a bad rash/hives on my left side and I ended up in bed all day for two days due to the lack of pain relief. I think this new formula doesn't help near as much as the old one did. Addict's are gonna get it from somewhere but the legitimate user will only visit his doctor. Im gonna have to see about this new "generic" formula that is supposedly coming out as i don't trust this new one. Im kind of caught between a rock and a hard place.
I feel badly for those of you that get the drug through legitimate sources for pain that is real and really need the drug. You are the ones who are made to suffer. You are suffering the side effects of the new formulation and the junkies will get a hold of the old stuff and still manage to get high. There is something wrong in this country if this is what happens to those of us who suffer chronic pain and just want some relief. I hope you can get a hold of something that works. Print off these comments and show them to your doctor. Let him/her know that many others are having trouble with the new formulation of the drug and maybe your doc can find you something else that will work. Good luck, God bless and feel better soon!!!

I did call the Purdue # I saw on here and was surprised that someone answered AND took a full report . So maybe they are starting to listen and compile some evidence/facts about this new formula. So please try calling all of you who have had trouble with it?
I just now received the paperwork from Purdue on the report I made back in September. If you receive a form in the mail, they want a LOT # or they won't further investigate the claim. I know it's not on many prescription bottles and it says you can this from your pharmacy so please make sure you get the lot # from the pharmacy to ensure your report is part of the investigation.
