Any other drugs that give a false positive for methadone?
no. --YES, other opiates, or cough Meds containing dextrmathoraphan (DXM), quinolone antibiotics, and lower incidences of diphenhydramine.
What over the counter medicine would make you test positive for opiates on a drug test?
Opiates - Substances or Conditions which can cause false positivesPoppy SeedsTylenol with codeineMost prescription pain medicationsCough suppressants with Dextromethorphan (DXM)NyquilKidney infection, Kidney DiseaseDiabetes, Liver Diseasewww.passdrugtest.com
Will a daytime sinus soft gel make you test positive for opiates?
Excessive (above prescribed dose) use of any product contain Dextromethorphan (DXM, DM) can result in an opiate false positive reading. If you take a dose as prescribed there should not be an issue tho.
Will dextromethorphan show up in a drug screen?
ok, there is speculation that at higher doses (500 + mg) of DXM, certain tests will show this as a "false positive" for PCP and/or opiates as long as 3-5 days after ingestion. Though based on experience, DXM does not show up on the basic THC/METH/COC/OPI tests, which are used in most probation departments. after taking 21 maximum strength Mucinex DM pills, (which total up to 1260 mg of Dextromethorphan Hydrobromide) I tested clean 4 1/2 days after ingestion. There is ongoing debate on this matter, my experience shows evidence that it is unlikely or impossible for DXM to show up on standard drug tests.
What can cause a false positive in a urine drug screen for angel dust?
High amounts of dxm(cough syrup)could, possibly ketamine too.
Can you pass a drug test while taking dextromethorphine?
Yes. DXM is slightly related to opiates but not close enough to cause a positive drug screen. It is very unlikely for one drug to cause a false positive on a drug screen for any other substance. Drug screens test for metabolites of specific drugs. All drug tests have a rating based on specificity and sensitivity. The higher the sensitivity, the lower the specificity. Basically it is only possible to have a false positive by using another drug that is very chemically similar to the positive test.
What causes a false positive for PCP?
The cough suppressant, DXM, has been known to cause a false positive for PCP. PCP, or phencyclidine, is also commonly known as angel dust.

What would cause a urine drug test to show positive results for propoxyphene other than the actual drug?
Propoxyphene is an opioid much like codeine, but is not considered to be much stronger than aspirin. Things that have been proven to cause false positives for opiates include:Poppy SeedsTylenol with codeineMany prescription pain medication (Norco, oxycontin,etc) Couch Suppressants that contain Dextromethorphan (DXM)NyquilKidney infection, Kideny DiseaseDiabetes, Liver Disease
Does DXM show up in a blood test?
DXM can possibly show up in a blood test if they are testing you for it specifically. Any drug or chemical can be tested for if the people know what they are looking for. Now, is it most likely going to get you in trouble because they find out you used DXM? Most likely not. The reason for this is because DXM isn't on a blood test more than likely as it is not really considered to be a "serious drug of abuse". So i wouldn't worry about DXM showing up in a drug test. However, supposedly it is possible to give a false negative of PCP, but that isn't confirmed as far as i know.
Can mucinex test positive for methamphetamine?
Yes! It did for me and my mother. I tested positive for amphetamines after taking mucinex that morning. They even sent my urine to the lab and it came back for 1000 nanograms of the amphetamines. Plus back a few years ago my mothers pain mangemeny doctor told her mucinex can come back positive for meth or ecastcy. No matter what other websites say. Its very VERY possible.
