Hello.

Welcome to Healthcare Magic.

I read carefully your query.

There are some otc medications that can cause a false positive result for Oxycodone in a drug test :
-Cold medicine that contains cough suppressant Dextromethorphan
-Diphenhydramine (Benadryl) ,an antihistamine drug used to treat allergy symptoms like sneezing,runny nose,itching etc
-A class of antibiotics called Fluoroquinolones

Usually Benzocaine doesn't cause a false positive result for Oxycodone.

Hope it helps.
Please feel free to ask if you have any question.

Kind regards,
Dr.Rovena Murati
