Pharmacy/False Positive
Expert: Layla Yeganeh - 7/7/2007
QuestionHi Ms Yeganeh,
I am a 56 y/o male who takes the following meds: Clonidine,Sudafed,Albuterol inhaler,Primatene tablets and Tylenol for headaches. I apploed for a job recently and had a urine drug test that was positive for Ritalin. I've never seen it nor have I taken it or any other amphetamines. Do you know if any of the above medications would cause this?
Help,
Alvin
AnswerHi Alvin.
I can see how this would be stressful, to test positive for something you have not taken. The average clearance time for amphetamines is 48 hours.
It is possible, here is a list I found that could cause amphetamine false positives and positives.
I wouldn't think it would be the Clonidine, or the Tylenol that would cause a + result. Most likely the sudafed, or maybe the other stimulants such as albuterol, and the Primatene.
I would ask to retake the test, give them a list of all your current medications, and if I were you I would not use the inhaler or put anything in my mouth for several days, just to be safe, as they may have you take the test on Mon. or as soon as possible to make sure you are being forthright.
Good luck!
