I am getting marcaine injections and am on lidocaine patches. I have a urine drug screen this week and am wondering if these can potentially cause a false positive for cocaine?

I was ordered to take a hair test and it came back positive for cocaine but I haven't done any! I have read that lidocane patches can cause this (which I DO take - and have rx for) and I'm wondering if this is true and/or if there's anything else I may have taken (antidepressants, etc) that I'm not aware of that may have caused this. PLEASE HELP!!! This is a custody issue and I"M TRIPPIN!! so any help would be appreciated. I also took z-pac (antibiotic)...would that have caused it??

No those medications cannot make you test positive. It would have to be a derivative of cocaine like marcaine, lidocaine etc.
