Why Does Oxycodone Show Up As Morphine In A Drug Test

Updated

I take 10 milligram oxycodone, 4 times a day. My doctor said my urine test showed morphine, but I don't take morphine, so why would that be?

Did you ever find out????? I'm on 5-6 percs per day, ran out way early so I bought some opana 80s and was told they would show as the perc. I'm now learning that it shows as morphine. So I have the same question. Just the opposite of yours. Did they ever explain how you got a positive one for the other? Is this something that may test as the same on a drug screening?

I take morphine and oxycodone.. If I took an opana, and I got a urine test by my doc..would I pass the test? Is oxy and morphine the same as one opana?

Opana is comprised of both oxycodone and morphine.

Google pharmacokinetics for the substances you took. Oh what the hell theses are the metabolites that will show up for each drug.
Morphine will only show up as morphine. It is the base opiate. When your body metabolize it, there will be a very small less than 3 percent trace of the hydromorphone metabolite. On that note, the test for two types, opiates and opiods. Opiates are the natural metabolites, opiods are a synthetic derivitive. OK back on topic, now that we know what morphine does let's look at the rest shall we. If you take codeine it will show up as codeine and morphine as the major metabolites and hydrocodne less than 5 percent as a minor metabolite. If you take hydrocodone(vicodin,norco,etc) it will show primary metabolite as hydromorphone and norhydrocodone. It will all show a secondary metabolite of dihydrocodeine. If you take hydromorphone ( dilaudid) it will only show up as that, no other metabolites. Those are the true opiate with the exception of heroin. When you do heroin it's active metabolite are morphine and 6-mam. All opiate metabolites are detectable in urine for up to 3 days with the exception of 6-mam which has a half life of a few hrs. That's what makes testing for heroin itself so hard. OK so now on to the opiods. These are basically gmo opiates. What I mean is man made to aid in efficacy and minor metabolite reduction. If you take oxycodone (pecocet, perxodan, oxycontin etc.) it will show up as oxycodone and it's primary metabolites noroxymorphone and oxymorphone. If you take oxymorphone(opana) that all it will show up as, oxymorphone. If you take naloxone it will show up as noroxymorphone. Then you have your others synthetics like tramadol but they don't matter. I hope this helps.

Just FYI Opana is in no way made up from oxycodone and morphine! Oxymorphone is a completely different chemical compound and drug than either of those mentioned!!
