hydrocodone vs hydromorphone

[Notgonnasay]

I take hydrocodone nightly and don't take hydromorphone but it showed up on my last urine test.....   I'm highly allergic to hydromorphone.    Would the fact that I've had to take Ibuprofen for sinus headache have anything to do with this showing up???   I also was taking Maxalt and/or Imitrex at the time.   Hydromorphone sends me into anaphalaxis shock within 5 minutes even at the smallest of dosages.... i'm really concerned as to why this has showed up on my urine test...and how?!?!?!?

"Hey Doctor, did you know that hydrocodone METABOLIZES into hydromorphone? Look, look what I printed out off of Google. I found it here: http://www.mayomedicallaboratories.com/articles/drug-book/opiates.html So, doc, I sure hope you don't think I'm taking hydromorphone on the side. In fact, have the testing company evaluate the QUANTITY of hydromorphone in my urine, and you will see that there is only a small amount, appropriate to what the HC metabolized into."

No one tampered with results.

hydromorphone is an active metabolite of hydrocodone.

I was drug tested for my employer and the result said “hydromorphone OR hydrocodone”.  Even though they are molecularly different, I guess they are similar enough on a drug test.  Or at my drug test lab anyway.

They are two different drugs with different metabolites. They may have simply conducted a screening test instead of a GC/MS test. As long as you have a valid prescription the employer should view that as valid.

Thank you,  I don't see him again until Feb... but I am definitely going to have a major discussion with him about this as he knows I am highly allergic to Hydromorphone.  Thank you for your help.  I am not happy about these results....it appears to me as though someone tampered with them....as this is not the only thing showing up that I do not take.

I would ask my doctor to test me again as it should not have showed up as hydromorphone
