I decided to switch to opana from oxycontin because the oxycontin was sort of not working as long as it used to.  Now I am on the opana er with oxycodone 15 for b/t.  Having bad side effects with the opana.  Bad constipation head aches and tired lazy feeling.  I did not have any of this with the oxycontin.  The opana did work a bit longer than the oxycontin.  What to do?   Can someone give me some advice on what i might do.  When i was on the oxycontin I came up a few short a couple of months and told my doctor.  I did not try to lie or hide it.  I told him exactly what was happening so he switched me to opana.  Heres my problem:  little or no side effects with the oxycontin and does not last as long and many side effects with the opana but the pain relieving qualities last longer.  What should I do?  I was on the oxycontin for 3 yrs.  I have been on the opana now for a week.  I try to keep giving it a bit more time but the side effects are still there? Should I wait for my next monthly doc appointment and tell him ( have to deal with the side effects for 3 more weeks) make a appointment soon?  Just some feed back would be nice.  I just dont want my doc to think i am a pain in the butt.  I am sure he has patients that need their meds adjusted and changed alot. Thanks

Shaw, How long have you been taking the Opana? Maybe you should wait and see what happens...sometimes it takes meds longer to really start working, so you might just want to sit tight. But, if they're not working very well you should call your Dr. I tried changing from 120 mg. Methadone to Morphine and went through a week of hell...I called the Dr. office every other day and after upping the doseage twice I finally decided that I had to go back to the methadone. Some meds work for some of us but do nothing for others...I would call...

You've only been on the Opana for a week. I switched a while back from Oxycontin to Opana, however I didn't get any relief from it.
When you go on a new or different medication, you really should give it at least two weeks and in most cases a month unless you are having severe vomiting or an allergic reaction to the medications. Oxycontin is one of the most constipating meds out there, but with any new opiate pain medication, you may experience constipation, along with some other side effects. Try using a stool softener and increasing your vegetables and fruits in your diet to help that.
The tired feeling and laziness feeling should disappear in a few weeks once your body becomes adjusted to the medications.
Most of the side effects go away once you re-adjust to the new medications.
I would stick with the medication that is giving  you better pain relief at the moment and see if the side effects lessen over the coming month. If not, then talk to your doctor about changing meds again.

On going back pain and neuropathic pain, failed back surgery, consult for scs, decided not to do that at this point.
Adhesive Arachnoiditis also......just what I didn't need..9/08- adding bilateral ulnar neuropathy with severe compression to the mix. They want me to see a surgeon for ulnar nerve surgery, but I'm not biting.
I've seen enough surgeons over the last few years.
