I'm currently on pain management and I went to my dr. Visit and I was told I tested positive for methamphetamine! I'm on 15mg xr adderall, 12mg. X2 a day, I take over the counter benzadrex and I use a vicks inhaler constantly, I'm a hairstylist and allergic to dogs. The last owner of my car road her dig around everyday and I havent had chance to deap clean the car so my sinuses are terrible. I'm adhd and ocd, but the nurse treated me as if I was guilty..And my husband goes to the same dr. And is on the same meds, his shows as amphetamines.

The nurse practitioner said that the levels reveal that I must have been on it the day I tested on my last months test, I honestly haven't taken any methamphetamine nor was I around it. But I use the benzadrex about 6 more times a day than recommend use. I told them exactly that, they are sending an email back to the lab to retest or break it down? They are supposed to call me in 5 to 7 days..Im also in a custody battle and I test for dhr and they send my test to a lab and I have never had a problem with my drug screens through their lab.

If this nurse had a 15 min conversation with me supposedly on methamphetamine when the visit took place...How could she have not made some kind of note of odd behavior? In my experience of people on methamphetamine they show sure tell signs!! I'm devastated! I don't know what to do, I left the dr.s office completely humiliated and felt like I was discriminated against by this certain nurse its like every since i've seen her 3x its been something and she acts like she could care less about anything going on in my life, unlike the other nurse I had seen 2x.. I'm lost ive prayed for god to reveal the truth, and are the labs able to break down the ingredients because there are so many harmful things in methamphetamine? Wouldn't they be able to tell the difference?

Novacaine does not have ANY epinephrine in it and would never cause a false positive for methamphetamine, not even for cocaine, which is a relative of the novacaine. Drug tests don't test for the actual drug, they test for what the drugs metabolize into, or the test results are designed to read for chemicals the body only produces when such drugs are used as the result of the use of them. Methamphetamine doesn't metabolize into pseudoephedrine, it derives from ephedra but needs to be made with many processes, first step is to process and isolate pure ephedra from pseudo with acids, then it needs to be processed with red phosphorus to create methamphetamine. It's a dangerous drug that gets very few false positives, however other amphetamines, such as ritalin and other ADD and ADHD drugs may have a better chance of causing these metabolites than something like novacaine. Think about it, when was the last time anybody has ever tested positive for methamphetamine when they went to the dentist?

I am on fed probation and was pregnant. I do not take methamphetamine and never have. I consistently failed on the screening (cup) BUT the lab it is sent to can differentiate and if ur friend doesn't know it is his right to demand it be sent to a lab. Prilosec can make u fail for thc and in my experience the lab could not tell the difference. I hope this helps ur friend.

Last I heard, Phentermine is illegal. But, in reading your post, what's the purpose of it?

Hi,

I know this may be old. But which article or reference did you find this list.

I need accurate and informative credible sources to document this information.

October - February I have had positive drug screens for Amphetamines (I take Dextroamphetamine Salts and Methadone) and NO METHAMPHETAMINE.

I suffer from asthma and use Pro Air albuterol and take Sudafed occassionally and sleeping pills (benedryl)

I know for a fact these are false positives yet CPS is trying to terminate my parental rights to my 6 year old son who was removed from my home with zero evidence (when I was testing negative)

I have heard of this situation several times where, for whatever reason, a Dr confiscates prescription meds from a patient. The answer is, Generally, NO. If you obtained a script legally, that is your private property, and no one has a right to it but you.
BUT, Nowadays, most pain management Dr's make you sign a contract agreeing to certain terms and conditions that the patient must adhere to. Basically, take meds as prescribed, don't get same meds from 2 different doctors, although that one is really hard to do nowadays because the DEA, and in Tx, the Texas Dept of Public Safety have a clearinghouse type of list that notifies doctors when they identify patients that are Dr shopping, etc.
So if in that contract it stipulates that the patient must surrender meds in certain instances, you have to do it or I'm sure the penalty is that the Dr will drop you from his practice if you refuse.

I've read a few answers to your question on here, and I saw one which caught my attention. (S)He who said that benzedrex will only test positive for amphetamines in an at-home drug test (5-panel dip and wait drug test) is wrong. Benzedrex may also give a false positive for methamphetamine salts. I say this from personal experience.
I'm on the verge of getting into a considerable amount of trouble over this.
It sucks.

This is a question I'd like to know as well. My doctor had said I've come up positive for methamphetamine 3 times now... He prescribes me tramadol. U would think he'd know right? So if u find out let me know plz.

Yes , some of your over the counter Cold &Cough medicine would react in a false-postive. Sudafed Is the most Common. Also some Adhd & Blood Pressure medicine can as well. Along with a Controlled 3 Category Medicine that is used to treat severe Obesity.
I hope this helps and puts you at some ease.

I am on trazodone, prilosec, lamictal, geodon, topamax, gabapentin, zaniflex and 800mg ibuprofen. Could any of these drugs show up on a urine screen as a false positive for either methamphetamine or amphetamine? I'm worried that I'm on the wrong meds since i tested positive for both.
