Benzonatate is not known to cause false positives on standard drug screenings, as it is not structurally similar to substances typically tested for, such as opioids or amphetamines. However, individual drug tests may vary, and there is always a small chance of unexpected results. If you are concerned about drug screenings, it's best to inform the testing administrator about any medications you are taking.
If the urine panel is a 9 panel drug screen, benzonatate will not show up.
what medications cause a false positive on a drug screen for marijuana?
yes
I can't see how.
Nitroglycerin will not show up on a standard drug screen.
It just gave me a false positive for marijuana for a drug screen for a job.
Can trazadone give a false positive urine drug screen for methamphetamine
It shows a false positive as Benzodiazepines!!
It should not cause a false positive on a drug test.
Yes. It will show up as Meth.
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.
A number of things can cause a false positive drug screen. A screening test is generally inexpensive to run. Tests for specific compounds are generally more expensive. As a result, more people will get a false positive on a screening test than will get a positive on the more specific test. Still, it will cost a lot less money to run an inexpensive test and then an expensive test.
