Besides, will cold medicine affect a drug test?
New to drug testing: Cold medicine's effect on drug test results. Some OTC medications, including decongestants, contain drugs such as pseudoephedrine, ephedrine, and phenylephrine. Unlike codeine and hydrocodone, these sympathomimetics will not produce a non-negative drug screen.
Also, will Sudafed make a drug test positive? Used for sinus and nasal congestion, Sudafed can be the cause of false positive tests for amphetamine or methamphetamine.
Also, does Nyquil show up on drug test?
With that being said, Vicks Nasal Spray can also cause false positives for Methamphetamine or Ecstasy. Vicks Nyquil contains pseudoephedrine which can show positive as an amphetamine.
Will phenylethylamine fail a drug test?
Of the ingredients in APEX-TX5, the only one that may cause a false positive for amphetramines in a urine test would be Beta-Phenylethylamine HCl, otherwise knows as PEA. PEA is quickly metabolized in the body so its potential to be present in an amount large enough to cause a false positive is very low.
