Why Would Oxycodone Not Show In Your Urine

Updated

I have a prescription through the VA for Oxycodone. I generally take 8 pills a day for arthritis pain management. The dosage per tablet is 5 mg.

I had to do a fasting lab (blood draw and unrinalysis) and per instruction stopped eating at 8pm and drank only water throughout the night and next morning. I awoke at about 4am and had to urinate prior to the lab.

Since I hadn't eaten, I did not take my morning dosage until after my lab and had gotten home. For some reason, my test showed no signs of opiates.

Because I'm also on pseudofed due to allergies, my screen showed methadone. So my doctor is concerned that I am selling my Oxycodone and using meth.

Any idea why the screen would not show Oxycodone since my prescribed dosage seems so high?

Well, your metabolism can have an effect on how long it is detectable in your urine and, in addition, if you weren't allowed to eat, that could have caused you to up your fluid intake, which would also flush it out of your system much faster.

Have you discussed this with your doctor? They should be aware of how these factors can affect it and, if I were you, I'd request another urine test, on a normal day, where you are eating, drinking and taking your medications, like usual.

I did two different months that the test showed no oxycodone in my system. I was takintg 90 pills monthly, 4 a day for pain management. Why would oxycodone not show up in my bloodwork and urinalysis. My Dr. automatically assumed I was selling my med's which I had taken two that day before I was tested. He discharged me from his care and he did this in front of his staff. I was eminate to him that I was not dealing drugs and need to manage my pain and other health issues. I can't see a new Dr. until 7/27. I am out of my blood pressure med, paxil and Gabapentin which CAN NOT come of of my system or I will be in a Chronic pain that no one deserves. Please give me answers vs. what my Dr. is assuming and is he not responsible to treat my life threatning issues such as heart disease med's?

My advice would be for you to quit trading or selling your pills for meth. Maybe you couldn't eat because your were twaked out and are just saying you had to fast. Taking a few pills starting a few days before the test while jacked up and not sleeping or eating isn't gonna get it. At least you were drinking water your poor body probably would have shut down on you. Your pain Doc probably saw through your B.S. as easily as I did. Surely you didn't expect an educated physician who has heard it all to buy that line. Give off the sh*%t and take your meds like you are supposed to.

To hearditallbefore Annie used meth as in short for methadone.and urine tests can be very shoddy.tell your dic that you want a hair follicle gas chromatography test to prove that ur not on methadone.or better yet do it yourself then sue his ass for negligence and malpractice.

Wow How can you accuse that person of trading his medication and you don't even know him! yeah you say you heard it all before but understand what has happened to him! I was in the emergency room one day because of my chronic degenerative disc disease I was given 2 hydrocodone I took them right in front of the nurse and then had to go back to the emergency room the next day they did a urinalysis and it did not show up in my system. You say you were a medical doctor but remember the Hippocratic oath... First do no harm! Apparently your ignorance and judgementment attitude has gotten the better of you. That's unfortunate for your patience :(

If you are a doctor I pity your patients. Your judgemental ignorant assumptions are bulls***. You have no business holding a medical license. Omg.. really? You weren't there. You're not the prescribing physician.

Re: Annie (# 2) Expand Referenced Message

Same thing happened to me. I take 40mg oxycontin sr twice a day. Not showing up in 4 urine screens. I have never missed a dose. I dont do any other drugs. No weed drinkin.. nothn. I don't understand how its not showing up. Im bedridden without my meds. I have psoriatic arthritis, bursitus, rheumatoid arthritis, no disc at L5 S1, bunions, graves disease, among other thjngs. Im on 11 meds a day. Yet im going to be kicked off what i need most for something out of my cintrol. I asked for blood test and another lab. Nothing. Im terrified of not having my meds. I barely get by as it is. Idk what to do.
