I took a urine drug test for my job and they said it came back positive for methamphetamine, but I dont use methamphetamine. I've just been real sick the whole week before and took a lot of diff. meds to break da fevers and my bad cough. What could have caused it to come up positive? ## Well, I can't check the specific medications, since you didn't list what you took, but there are some cold remedies on the market that can give false positives for Methamphetamine. Some examples would be: NyQuil, Tavist-D, Sudafed and Dimetapp. Can you post back with more information on what you took? If so, I'll gladly check them for you. ## I also got a false positive for methamphetamines on a drug test after taking perscription Nalex-A , a decongestant. Is there some response from the ... ...

How do you prove you only take sudafed when you show a false positive drug test for methamphetamine and you never did drugs except sudafed 120mg 2x daily non drowsy ## Ask for a GC/MS confirmation test. It's the "gold standard" use the gas chromatography mass spectrometry method....... Will show negative for meth if you didn't do methamphetamine, or consult a MRO (medical review officer) , doctor trained to interpret drug tests. ## Nice try. Only taking sudafed will not show up as anything. Your caught! Sudafed needs to be chemically altered in order to become meth!!!!! Therefor if it showed up as meth, IT MEANS YOU DID METH! Any further bull sharting will only make you look dumb. If sudafed only by itself showed up as meth than you are an alien and need to be deported b... ...

Amphetamines and methamphetamines false positives
11 Replies RSS
I took a drug test at work and it shows positive for amphetamines and methamphetamines and I don't do illegal drugs. I take latuda, pristiq, neurontin, sudafed, adderall, nasal spray at times, bc powder, and vitamins. How is this even possible? I can lose my job. ## Hi Girlygirl, sorry to hear about what you're going through. What you have listed as your medications (especially the Sudafed, Adderall, and nasal spray) are most likely the reasons that your lab work came back positive. If possible, your best bet would be to show proof that you are prescribed these medications, or a doctor's note, so that they can see the reason for such results. If you are unable to gather that information that I would definitely mention that you are taking over the counter Sudafed for allergie... ...

My daughter failed a drug test. She claimed she only took bc powder, ibuprophen, and trazodone..... Can u fail a drug test for methamphetamine with this mixture? ## Ibuprofen wont give a false reading for meth! Phenylalanine,pseudoephedrine (sudafed,for hayfever) & trazodone will both give a false positive though! :) Just like a reading for opiates will produce a false positive for morphine! & codeine will give a false positive for morphine also. ...

prescription and non meds that cause false positive for methanphatemine urine tests
1 Reply RSS
I just spoke with a pharmacist gave him a list of the meds I have been taking : morphine 30mg, diovan, hydrochlorothizide, valsartan, hydrocodone 10/325, bisopropolol, sudogest, pseudoephederine, aleve, pain reliever pm. He says none of these will cause false positive urine test results for methamphetamine although I keep testing positive and I have not used any of that stuff! Can you tell me why this is happening cause my po is going to throw me in jail. I really need help with this please ## Since you took sudafed, that could have caused it. Sudafed is used as an ingredient in methamphetamine. That's why you have to give them your ID just to buy it. Request a more detailed test, and it will show that an otc drug caused it to pop up as positive. ...

what over the counter medication can cause false positives

I am clean but probation says i tested positive for Methamphetamine. what med or combination could have caused it? ## I have heard that sudafed (pseudo ephedrine) can cause false positives for meth. Google it and see what you come up with but I have heard this more times than I can count. I don't have any experience since I never take cold/sinus medication. Too many I am allergic to so I stay away from all of them. Good luck and let me know what you find out. It's crazy, but it seems the more "scientifically correct" these drug screens get the more false positives come back for various drugs. Its not fair to a lot of people and you would THINK your doctor would know about other drugs that can generate false positives.....but, they don't seem to know or they just don... ...

sulfamethoxazole-tmp ds/possible drug screen false positive
2 Replies RSS
I am taking this medication along with levothyroxine for my thyroid and xanax for anxiety. Is it possible that these drugs mixed together along with sudafed can cause a false reading for methamphetamines on a swab test? ## It is highly possible that it was just caused by the Sudafed. The Pseudoephedrine in some of their formulations has been known to cause false positives for various types of Amphetamines, including Methamphetamine, since it is actually a distant relative. Are there any other comments or questions? ## Can sulfamethoxazole cause you to fail a hair follicle drug test for Methamphetamine? ...

Please explain this for me. I haven't done any drugs, just the medications listed? The celexa Tylenol b12 extreme zinc potassium naproxen and some sort of sinus pill few days ago? Yet I fail for methamphetamine and amphetamine how what's going on? ## Naproxen will give a false positive reading for barbiturates, (Cocaine/Speed/etc), Phenylalanine or Pseudoephedrine in Sudafed will give a false positive reading for Methamphetamine/amphetamines. ## the sines pill has afed in it that would hit on the test try dropping what u can even if a doc say youre good cuz state and gov workers look on a scale of levels the less they see the less of drug testing ## So when they send it to the lab can they tell it wasn't meth ## Can celexa, zany 1g, and Lasix 20 mg show a faulse posative on ... ...
