If they test for alcohol it could show up as well depending on the time you took the medicine and the time you took the drug screen. Nyquil has a high amount of alcohol in it. It also can contain pseudoephedrine which can show positive as an amphetamine. If you do get a false positive, ask for confirmation by GC-MS-gas chromatograph-mass spectrometry. This test is more expensive and you may have to pay for it yourself but it will differentiate the false positives. It is used to confirm or dispute false positives. It is extremely accurate.
