What Can Make A False Positive For Methamphetamine?

I had a test done that came back positive for methamphetamine. I was on metoprolol, and claritin-D. Which of these can come back as a positive for methamphetamines?

Hi tina - it is possible that the Pseudoephedrine in Claritin-D is what caused the test to come back positive for amphetamines. You should definitely bring up the fact that you are on this medication because that should be factored in. Hope this helps!
