❓ Will promythazine cause you to fail a drug screen?

I'm a little confused by your question versus the categories you chose for it. Promethazine (the generic name for the prescription anti-nausea medicine Phenergan) is not an amphetamine, and is not tested for in standard drug tests. However, promethazine has a formulation that includes codeine, which is a narcotic pain reliever and antitussive. Codeine will cause you to test positive for opiates.

This is perhaps one of the most common offenders when it comes to failed drug tests. Sudafed is often mistaken on pee tests for numerous hard-core drugs. This is because, like most cold remedies, Sudafed’s main ingredient is pseudoephedrine, which is a type of synthetic amphetamine. Avoid Sudafed at least 48 hours before a drug test.

Sudafed products, such as Mucinex DM contains two key ingredients: dextromethorphan and guaifenesin. Dextromethorphan can potentially cause you to get a false positive for heroin, opiates, and morphine on a drug test. Guaifenesin is an expectorant that helps thin and loosens mucus in the lungs, making it easier to cough up the mucus.

No, you should be fine. But, if for some reason you do, they will most likely confront you about it, then you can refer them to your doctor. I've had to do that before when I had a Rx and it made me fail a drug test. It all worked out once they talked to the doctor.

Yes, unfortunately sudafed can cause a false positive for cocaine along with other drugs such as amphetamines. Fortunately your urine drug screen was negative.
