Question
I am currently taking small daily doses of trileptal and fluoxetine. Is it possible for these drugs to cause a false positive response for cocaine on an over the counter drug testing kit?

Answer
Prozac, and trileptal= cocaine,,, I doubt it.
But always tell the testing person what medcations you are currently on.


Popssible Cocaine False Positives  

Amoxicillin, tonic water, kidney infection, kidney disease
liver disease, diabetes.

*Some of the drugs used to treat kidney disease may cause a false positive but the disease itself does not.


If I were you and I had not used cocaine, and wanted to get my name cleared I would ask for a retest. Your company should always provide the services of a Medical Review Officer (MRO), a person who is a licensed physician and who is responsible for receiving and reviewing laboratory results and evaluating medical explanations for drug test results.

"The MRO helps protect both the rights of the employee being tested and the employer requiring the testing.

MRO "reviews" include the interpretation of urinalysis test results reported by the testing lab to ensure a scientifically valid result.  Especially, the MRO attempts to determine whether a legitimate medical explanation could account for any "confirmed positive" result reported by the laboratory. This duty is fulfilled through telephone or in-person interview with the specimen donor and by giving the the donor an opportunity - through their doctor or pharmacist - to provide evidence of legally-prescribed drug-use that may have caused the lab-positive.

When the MRO can determine that a legitimate medical explanation exists, the MRO will then "overturn" the results reported by the lab and, instead, report the "final" result to the donor's employer as "negative".  While a small percentage of companies will not pay the extra expense associated with MRO services, such services do greatly enhance the validity and reliability of the overall drug-testing process.  They also help ensure fairness to the donor and offer more protection to the employer in any case of later litigation due to a "positive" drug test where the employee has been suspended or fired."
