Question 1

i recently tested positive for amphetamines and methamphetamines. i take prescription wellbutrin and vistaril. but i honestly do not and never have used meth. what could have caused me to test positive for both drugs?

Accepted Answer

: There can be false positive results which appear on toxicology screens secondary to prescription medications and laboratory errors.  Discuss results with your doctor, and if necessary and vital, repeat study while placing your regular medications on hold if this is safe for you.

Question 2

what medication will cause u to test positive for meth use?

Accepted Answer

Several!: Alpha Methyldopa and Clonidine can cause false-positive urine drug tests for methamphetamines; so can nasal decongestants, ritalin, various cold remedies containing ephedra compounds.

Question 3

can provigil cause positive drug test for meth?

Accepted Answer

It should not: Although Provigil is a stimulant of sorts, its chemical makeup is dissimilar to amphetamines and should not cause a false positive drug test.

Question 4

can using meth cause false positive pregnancy test results?

Accepted Answer

: No, abusing "meth" does not cause positive pregnancy tests.  But this is indeed a deadly habit, and you are urged to address this ASAP, especially if you are about to have a baby.  Contact a drug rehab program now, get off meth and all recreational drugs and reclaim your life.  It is not too late.

Probably. : Best to stop using illicit drugs. Get help with aa/na.

Question 6

will acetaminophen show up positive for anything on a urine test. and if so what will it show up as? also can hydrocodone cause a false-positive for meth on a urine test? i've heard there's a lot of things that can do that.

Accepted Answer

Urine toxicology: Employers don't usually care if you take acetaminophen or paracetamol. Hydrocodone is an opioid, related to oxycodone, morphine, etc while meth is in amphetamine class, so they won't cross react. However, many common consumer items can cause false-positives so do be careful.

Question 7

took drug test doctor called and said it came up positive told them i take tylenol 600mg & arthritis pills that r 650mg and if it would show up on test cause they said mine was 1400 and said was positive for meth i asked how much was drug from pills?

Accepted Answer

: Not sure what your question is, but drug tests are very specific and there are no meth components in Tylenol.

Question 8

i am wearing a sweat patch for drug screening & it came up positive for meth & i haven't used at all. i did 2 hair folicle test and the first can positive for meth. haven't used in over 3mo on hydroxizine can this cause false positive?

Accepted Answer

: Methamphetamine use of any kind or quantity will be picked up on drug tests for approximately 90 days. (plus or minus 10-15 days) Hair follicle tests can be positive for 6  months. Hydroxizine is not known to cause false positives for Meth. Ask for another test to be done or more specialized test such as gas chromatography-mass spectrometry (GC-MS) or high-performance liquid chromatography (HPLC)

Question 9

i have taken 2 separate hair follicle test for new jobs both test came back positive for meth i have been clean for over 5 months. could one of these medications cause it? diphenhydramine reglan tordol zofran losartan?

Accepted Answer

: One detailed study showed that chronic meth use can be found in hair tests up to 153 days after being stopped. As for false positives with those meds listed,your pharmacist will possibly have that information but I'm dubious that they would test positive.

Question 10

what could cause me to test positive for methamphetamine and amphetamine on a urine drug test that was confirmed using gc-ms when i do not use drugs?

Accepted Answer

What DO you take?: Someone else's specimen may have been mislabeled as yours. Or, you may be taking a medication that is "cross-reactive" with amphetamines and caused a false-positive result. Labs usually include such cautionary information in their reports. Go over the lab report and your meds with the ordering physician.
