Allergy Medicine False Positive On Hair Follicle Test

I failed a seven panel hair follicle test. I have (for years) taken medicines for add (currently amphetamine salts) and I do use seasonal allergy medines/ asthma meds when needed. Could any of these meds have caused my false positive?

Hi elizabeth,

Are you saying that you tested positive for allergy medication after having took amphetamine?

I did find out that allergy pills (antihistamines) can sometimes produce a false positive for amphetamine. But I'm not sure if this is what you are referring to, since you did mention that you frequently take amphetamines.

Also, hair follicle tests can detected a number of different drugs that you may have had over the past 90 days, that could also attribute to a false-positive.

Have you asked about getting re-tested?

Yes, there are some medications that can cause false positives.

What did you fail for and what specific medications do you take?

This information would enable me to check the details for you.
