Benadryl will show a false positive for methadone I’ve done it a few time and paid for them to send it off for conformation at the lab it always comes back as a false positive
Idk if you took any Benadryl but if u did I would have them send it to the lab for a complete analysis

Read all the causes for Methadone, make a copy of the list, keep original, and have your results to show false positive.

I am on 2mg oxicodode three times a day for severe back pain. I had my urinalysis come up and say I was posative for methadone. The only other medications I take is Lamictal 10mg twice a day klonapin 1mg twice a day. My dr now thinks I broke the pain contract. I never have taken this drug. Does any one know why it came up in my test?

That's not true. I'm on lamictal, ability & wellbutrin. I consistently test positive for PCP & methadone. They've even stopped sending my ua to the lab because it always turns up that I did no drugs at all.
