False Positive drug test for cocaine

Dear Ask The Doctor: Are ther any medications that would effect the outcome of a drug test. I have never taken any illegal drugs and i take many random drug tests for work and my last tese was positive for cocain and i am wondering if any of the many medications i take can effect the test.thankyou

Dear John: If done correctly, drug testing for cocaine is pretty accurate. Most drug tests that check for cocaine look for benzoylecgonine, a product of the body's metabolism of the drug. That said, some medications and medical conditions can sometimes trigger a false positive for cocaine. These include:

• Amoxicillin
• Topical anesthetics derived from cocaine (does not include lidocaine or novocaine)
• Liver disease
• Kidney disease
• Diabetes

I would suggest that you speak to your doctor if you are suffering from any of the above mentioned issues.
