Please tell me if orajel or ambesol can cause a positive for cocaine?

Question

I recently came up positive for cocaine and I do not use cocaine in a job related urine test. The only I take is Ibuprophen and ambesol and orajel for my toothache for the last 2 weeks.

Answer 1

Apparently, diabetes, kidney, and liver problems are the leading causes of false positives.  Reportedly, amoxicillin and tonic water can also do it and I would guess that benzocaine (Anbesol/Orajel) could give a false positive in a saliva test, though I doubt it would show up on a urine test.
