Opana ER positive test

Hello.  I am prescribed Oxycodone and Hydrocodone for pain.  My doctor told me that my last drug screening came up positive for Opana ER.  I have never taken Opana.  How in the world could this have happened?  I know many people won't believe me, but it's the truth.  I'm just trying to figure out how this could happen.  Any help would be appreciated.  Thanks!

Thank you for responding.  I have a message in for the doctor to provide me with a copy of the results.  After I posted this, I researched online because I was so upset, knowing that I hadn't taken the Opana ER.  I found an interesting study that was done by a doctor a few years ago.  She indicated that for patients that take 100mg or more per day of Oxycodone - that 93% of the time the urine test comes back positive for Oxymorphone, which of course is what is in Opana.  She studied a whole bunch of pain mgmt patients and this is what she found.  She also said that many doctors that write for narcotics are being irresponsible by NOT educating themselves on the lab quirks (my word, not hers, ;o) and falsely accusing patients of taking drugs that they many times have not taken.  This is one of the issues that comes up, quite a bit from what I understand.  I'm assuming that he knows that, because he wrote my scripts for me - I can only assume that if he TRULY believed that I had taken the Opana ER that he wouldn't have written my regular script.  But on the other hand, next week I start pain management, so he may have just decided to do it this last time.  I don't know, but I am upset that this now is going to be on my record.  I've printed the study and intend to keep it in case my new pain management doctor comes up with this same crap.  I'll post once I get my results.  Thanks again for responding.  I really appreciate it.  Happy New Year!

Your doctor specifically said "Opana ER"???

That's a bit odd.

Opana is just the brand-name for Oxymorphone, and the ER just means "extended release" (as opposed to the IR, "instant release").

A doctor telling you that you tested positive for Opana ER would be like telling someone that they tested positive for Norco 10/325.

Drug screens/tests just aren't specific enough to determine brand-names of drugs, let alone whether it's the ER or IR version of the drug.

Talk to your doctor and tell him you'd like to see the results of the test, and ask him how he came up with "Opana ER".

There ARE other brand-names on the market for Oxymorphone besides Opana, so I'm curious what he says...
