why would adderall not show up in a pee test?

I take morphine, Percocet, and Adderall daily, and I had to take a **** test for my pain doctor, and Adderall didn't show up on 2 test, I drink a lot of pop, water, and also been on antibiotics at the times they test me, could that make Adderall not show up?

Your body may be metabolizing medicine differently than others. Same thing happened to me. Once with my Xanax and once with my aderall. I go to the doctors office 2-3 days before any possible urine screens and MAKE a nurse physically watch me take my meds so if they don't show up I am not to blame. The most frustrating thing is knowin you take your meds and having someone treat you like trash and basically call you a liar because their test is bunk or your body metabolizes it differently. Make them watch you take it. I'm so sorry that happened to you!!!

    Good points, thankyou.  Reminds me that a hair follicle test will show stim meds from over a much greater time period.

Assuming that your pain doctor knows you are prescribed to Adderrall and are supposed to be taking it daily and it is not showing up, then maybe he doesn't think you are the one actually taking the Adderall, even though you are prescribed it?
Maybe he/she believes that since the urine test concluded that the drug absent from your urine that even though you are the one prescribed/getting this drug filled, that you are not the one taking it and someone else is... Because of this, your pain doctor might assume that you might be an 'at risk' patient for prescription drug abuse because of you show signs of inhibiting typical behavior pattern signs of someone who actually does abuse prescription drugs (i.e. getting a prescription and having it filled on behave of someone else, or getting it filled and selling it for street value)...
Listen,  I am not saying that you are doing this or not doing this - but, just think about it logically, if you were a doctor, wouldn't you be concerned about prescribing pain meds (that carry a high street value when sold) to someone who is says they take a drug that is prescribed to them regularly,  (especially a drug that also carries a high street value, similar to pain meds) and their urine does not test positive for this drugs? Most doctors would, because if the patient is telling you one thing and a medical test is telling you another - Then the doctor can only logically conclude that the odds of the patient being dishonest with them vs.  an error simple urine test is definitely 99.999% that the patient is being dishonest and flag you as someone who is a 'high risk' to prescribe to.
Listen, if I were you and I really did take addreall like my doctor had prescribed me too - I would make darn sure that my pain doctor knew this and would find ways that would prove it so (request filled reports from your pharmacy, request a blood test instead, etc.)!
Without any hard proof (like a urine/blood test) the doctor can only assume the worst. I know, it is totally unfair that you would have to keep going back and forth like this just to prove that you are being honest; however, your doctor's license is on the line here and he/she needs to be 100% comfortable with prescribing you these type of drugs before he/she does so...and unfortunately, without any hard medical proof (like a positive drug/urine test, etc.) it will be very hard for them to do so.
Good luck and just remember - your doctors perception of this situation is reality, change his perception and you change the reality!

    I agree.   That's why I think something else is going on.  And as long as he had taken the stim meds probably 24 to 36 hours before the test, it easily should have shown up.

Adderall can counteract the "high" some people get from pain meds, But it is still odd that a doctor would conclude that a person is abusing pain meds based on the lack of Adderall in a patient's system.

   Ok, thats the problem.  There is no reason why I can think that they would stop your pain meds if the stim meds were not showing up.  To me, I think its possible that you misunderstood what was going on.  
   Stim meds should show up for at least one day after ingestion.  Typically it will show for two to three days after (http://www.erowid.org/chemicals/amphetamines/amphetamines_testing.shtml).
   Thus, if you have taken the med within probably 48 hours of the test, it should show.
   The question for your doctor is why is he stopping the pain meds if the stim meds don't show up?  You do need to know what is going on.  My guess is that the stim meds are showing up - if you are taking them as prescribed and that is why the doctor is making his decision.  
   Both pain meds and stim meds can be addictive. If you are seeing two different doctors then maybe its time for the doctors to talk to each other.

    Ya, thats the point.  Adderall will show up in tests - and its a pretty easy drug test.  I wonder if your pain doctor does realize you have a prescription for it?  Perhaps he feels that you are abusing stimulant medications?  Anyway, it all leads back to you finding out from him what is going on.

      Not sure why your pain doctor would WANT it to be there.  I would think that if anything he would NOT want it to be there and stopped your pain meds because it was there.  You might want to clarify this with him.

They must not have tested for it.  

When I had to take a pee test (for work) it came up as amphetamines.

Always disclose the fact that you are taking adderall before a urine test.  Bring the current prescription bottle and show them.  

I was working for the state of California and that was all they required.

   My only guess would be that they were not specifically testing for stim meds.   It normally should show up no matter what you are taking.
