I tested positive for cocaine on a drug screening. I don't

Customer Question

I tested positive for cocaine on a drug screening. I don't do any illegal drugs at all. Never have. I take fiorcet for migraines & had 4% Citanest with dental work two days before my drug test. The test isn't showing positive for forget at all but positive for cocaine. What could be causing this false positive ?

Citanest or Prilocaine can potentially cause a false positive cocaine test. Other possible culprits include antibiotics like Amoxicillin
Ampicillin.
Coca tea, Coca leaf, Coca flour, Coca oil can also cause a false positive cocaine test.
