I tested positive for Meth in a urine test but did not take it. Could it have been one of the following?

Question

Sudefed, Sudefed cold and allergy, Benadryl allergy & sinus, Alka Seltzer Plus, Alavert, Advil, I also was taking Phentramine (Hoodia Guarana). Please if someone with knowledge could let me know, kids have been taken because they say I am lying.

Answer 1

I know poppy seeds in muffins can sometimes cause bad drug tests, don't know if that helps at all.

Answer 2

I'd put a vote in for the Sudafed. (Sudafed = Psuedoephedrine = "fake" ephedra) and Ephedra is an amphetamine.

"Drugs for FALSE positive on Meth-
Dristan Nasal Spray, Neosynephren, Vicks Nasal Spray, Sudafed, etc... and others containing ephedrine or pnenypropanolamine. Over the counter appetite suppressants which contain Amphetamines. As the cross reactive list suggests at the back of the book, amphetamine false positives are the MOST common. Recent articles in the Journal of Clinical Chemistry, Vol.38 No.12 (1992) and Vol. 39 No.3 (1993) warn that medications containing chloropromazine, fluspirilene, and others may yeild a positive when tested for amphetamines"

Earlier in the article it said there were 250 OTC medications that can cause false positives on meth urine tests.

Answer 3

No, the drug test specifically test for ampehtamines, benadryl is in a totally different catagorey as anphetamines as well as the other ove the conter drugs. Adderall, Ritalin, and other prescription stimulants contain some of the same ingredients, did you take an crystal meth specific test? If no other drug would cause a postitive. Unless you have a faulty test then no other drug will affect your results. Take another test. If you still test positive, you positively took meth.

Answer 4

yes, any of those could have sudafedrine in them , ask your pharmacist for the other common ingredients that could cause you to fail.i had mine taken 2 yrs ago, but proved the antibiotics id taken from a friend was dirty like meth, those pills are used to make meth so if i was you i would not even keep them in the house, the main over the counters are:walfidrin, sudafed and benedrin in pink box, hope this helps and good luck to getting kids back,,,

Answer 5

urine test?? the first one?? You have rights man, if you are clean ask for a hair sample to be done, and be adament about it. Lots of things can cause bad results but usually you have to have taken a lot of something. like poppy seeds, you would have to eat more than any human would ever consume in a lifetime. people that fail a test on a false posotive its usually either a lab error, or that person is trying to get high of something else.

Answer 6

Sorry to here about your children being taken- My children were removed from me about 2 years ago because of a meth addiction. If you REALLY did not use, it probably would be ANY cold/allergy type medicine that you had been taking on a regular basis.

Answer 7

Usually before you take a urine drug test, you will be ask to write down any medications you are taking, or have taken within the past thirty days.

Did you tell or write down the drugs you were/had taken?

I know that there are over the counter cold/sinus medications used to manufacture Meth.
One comes to mind...Coricidin.

Hopefully, you have a lawyer.

Answer 8

It could have been the pseudoephedrine in the Benadryl and Sudafed (note spelling) or it could have been the phentermine (again note spelling). If you can arrange to take the urine test again, allow 5 days for all OTCs to clear your systems completely and do so. And stop taking so many redundant medications.

Answer 9

Q Will commonly ingested substances such as vitamins, penicillin, aspirin, caffeine and acetaminophen (Tylenol), affect the results?
A: No. The tests are drug and drug metabolite specific. Because these commonly ingested substances are chemically and structurally different after metabolized by the body from the drugs being tested for, they will under most circumstances not interfere with or compromise test results.

Answer 10

It would depend on how they tested your urine. Most good drug tests could weed out the Rx meds from meth. A better question is have you been around meth being made or someone who has or does it even if you don't? Theres a reason they hazmat meth labs that s*@# is caustic.

Answer 11

I have never heard of any of those things individually causing anyone to test positive, but I guess it's possible. Perhaps you had too much sudafed or Hoodia in your system and an amphetamine is an amphetamine.
