Positive for suboxone and oxy.
Date: 4/6/2013
I went to my sub clinic the other day. the doctor has me on suboxone...he gave me a random. and the test showed positive for suboxone and oxy. why would it show positive for oxy. they are sending the urine to a lab. will it come back negative or positive?
Jamie

AskDocWeb: According to the American Association for Clinical Chemistry suboxone (Buprenorphine) may test false positive for oxycodone (Reference 54). If you haven't taken any oxycodone then the confirmation test from the lab will come back negative.


Is there any way to be sure?
Date: 4/6/2013
My husband is on various prescribed medications, for chronic back pain, diabetes, and cholesterol. In the past he has also had an issue with illegal drugs. His drug of choice Cocaine and Crack-cocaine. As I read the false positive list, I realized that codeine can be a false positive for cocaine as well as diabetes. After claiming to be clean for a few years now, I recently discovered drug paraphernalia used to snort cocaine. His claim, is that he has began to snort his prescribed medication to take effect faster. He is willing to take a drug test to prove his innocence but with so many meds he's on I know the reading might not be accurate and the possibility for a "False Positive" is almost certain.

Is there any way to eliminate a "false positive" and directly confirm if it is Cocaine being used? The evidence is more than incriminating, I know. My trust has been broken once again and I'm hoping there will be a way to know for sure if I am indeed being lied to. Please give me your expert opinion. My marriage is in deep trouble.

AskDocWeb: We are not marriage counselors and can't help you with that. For eliminating false positives on urine tests the "Gold Standard" is the GC/MS test used by government certified laboratories. They are so reliable that their results are used to confirm or deny drug abuse in a court of law. For a list of SAMHSA certified laboratories see page 185.


Grrr...

I supposedly tested positive for methadone... I guess it goes to show how accurate the testing can be. Did they just mix up my results or did the test not work right? With the amount of testing going on there must be a lot of negligence; what a cash cow. There is no reason for methadone to show up in my urine sample... Grrr...

Will compazine show on a drug test for drug abuse as anything?
Dixie

AskDocWeb: Compazine has not been reported to show up on urine drug tests for drugs of abuse.


Positive for Suboxone?
Date: 4/9/2006
My son recently tested positive for Suboxone. He recently was put on prescriptions meds Levofloxacin, Fluticasone and Venlafaxine. Could any of these cause a false positive?
Alan

AskDocWeb: Sorry Alan, our database doesn't list anything that would test false positive for Suboxone. Of course that doesn't rule out the possibility of a false positive so the additional testing is recommended to confirm the result. If it comes back negative then he is in the clear.


How did i fail?
Date: 4/9/2006
i just took just drug test for a job yesterday i tested positive for methanphetamines and opiates im drug free i just drink i take my meds daily which is lisinopril hydrochlorozide and zantac 150 for my acid reflux how did i fail?
Carl

AskDocWeb: Those medications would not have tested false positive for opiates. However, Zantac (ranitidine) is known to sometimes test positive for methamphetamines (References: 33 and 52). Since the test was for employment you will likely have to get a confirmation test to prove you are not a drug abuser. Just so you know, the confirmation test has to be performed on the original sample, which is kept for a limited amount of time.


Hum...

Jeremy

AskDocWeb: Is that a statement or a question?


Not their policy to retest
Date: 4/9/2006
just wanted to add my question, what if you take methadone, and the doc says your UA is pos. for buprenorphine and I did not take it. got discharged asked her to retest and she says its not their policy. now I don't have my pain meds for my back and have been on it for about 1.5 years?
April

AskDocWeb: Unfortunately that is the policy of many clinics that treat pain. That is the result of laws that treat people with certain medical problems as if they were criminals. Hopefully you will learn from that experience and apply that learning in the future. In looking for a new source of treatment, find out what their policy is should a urine test come up positive. You want a care provider that will do a confirmation test, or at least allow you to pay for one, and not fire you on the spot.


Guilty until proven innocence
Date: 4/10/2006
I have been going to pain clinic for 2 years and not once have I had a problem with my urine screens. Then one month they say I tested positive for THC. They do the cheap in house tests and I take numerous medicines including promethezine which is on the known list. I also at that time had a kidney infection which I can prove. I even went back and had another urine screen that showed all negative. but they have discharged me from their care stating i tested positive for thc during the most recent month and know nothing of what i was talking about the previous month that they in fact told me that i did. this is absurd and want to know how to prove my innocence. thanks for any help!
KC

AskDocWeb: If you are talking about proving your innocence to those at the pain clinic, the only proof that they are likely to accept is the results of a GC/MS confirmation test performed on the original sample that tested positive for THC. That may or may not be possible because laws vary from State to State. Even within a single State the company policy of pain clinics can vary widely from one clinic to the next. To start with you may want to Adask a Lawyer about what options are available to you in the state where you live.


68 year old Nanny
Date: 4/10/2006
On 3-20-13 I took 1-100 mg Celebrex capsule and within 10 minutes I went into full anaphalaxis. I realized what was happening and called 911 immediately and was transported and treated at the local hospital. I came home AMA as I had 6 animals at home that needed care. Boy was that a dumb move! I went to my PCP the next day as I was advised to do. I have refused all meds except tramadol 1-3x per day for ruptured disc's, arthritis and I need a hip replacement. I also have neuropathy in both lags and feet because of b12 deficiency. I also have hepetitis C from a blood transfusion when I had 80% partial gastrectomy due to being over prescribed prednisone when then disc's were ruptured in a MVA in 1976, the surgery was done shortly after the prednisone caused the ulcers. For years I have had malabsorbtion because of this surgery. This has made getting rid of pain a nightmare! I have taken 3-4 asprins at a time or 2-3 advil or aleve to help what the tramadol doesn't.

After the anaphalaxis my PCP decided that something called narco would be appropriate and prescribed 20 to be taken 1-6 hrs. I asked to have only 5 until I could see if they would even work with the malabsorption. He explained that I would have to take a urine test to receive this medication. I did this without reservation. Approximately 1 week later I received a letter in the mail telling me the urine screen was positive for tramadol, which was expected - I am also taking Restoril 1 per night because of the burning neuropathy in my feet and legs. But it also said I was positive for Serax and THC. I have never taken Serax or smoked Cannabis!!!!!!

I am a 68 year old Nanny and was admonished by this letter to stop the Serax and Canabis or they would terminate me as a patient. I immediately took this letter to my employer who is a Kidney Dr and she advised me to immediately find a new PCP as it appeared at best my Physician was not knowledgeable of false positives at worst protecting himself in case I decided to sue him because of the almost fatal reaction to the Celebrex.

I am now waiting to receive the 1st responders report of medications given by them and from the treating hospital. I have NEVER taken ANY meds not prescribed by my PCP and certainly not smoked eaten or had anything else to do with cannabis. In the mean time could I have been given anything form the 1st responders or hospital that would cause these results! Could my B12 injections, vitamin supplements, all necessary because of the malabsorbtion do this or could my Hep C have any connection.

I know this sounds rambling but it has taken me 2 weeks just to get rid of my anger at my PCP who immediately assumed I had done something wrong. By the way He also wants $1.35 per page for my medical records which I need to complete my report to the FDA and Phizer. When I ask if he was making a report he said no that they already know this is a side effect! Thank You for your time. Sincerely,
Fran
