I tested positive for meth. Have never ever, and would never ever take meth!! The only thing that could cause this is the diphenhydramine that I take. I do take more than recommended. The confirmatory was also positive. And nobody can say that is impossible, because it is possible it did happen!!!!!!!!'''
I take diphenhydramine on a daily basis and never test positive for anything on a 12 panel drug test which includes EtG testing.
I'm currently on probation and am in a very strict court program where I take anywhere from 3-7 UA's a week. I take diphenhydramine every night as a sleep aid, and in all honesty, I take a more than the advised 30 ml dose.
All of my test's so far have been negative for everything. I was concerned I may test positive for alcohol or a benzo. The staff at the UA company told me the only way you can only test positive for anything would be by drinking several bottles of diphenhydramine. I know everyone here is looking into this for different things showing up, so I hope this helps, but you may want to look into what else you are taking that could be causing a positive on your test.
If anyone is concerned about diphenhydramine showing up as alcohol on a test, you MUST BE SURE that the diphenhydramine you are taking does not contain alcohol in it. For instance the brand Zzzquil has two versions of diphenhydramine as a sleep aid, one that contains 10% alcohol and one that does not contain any alcohol. You just have to be sure to check the inactive ingredients as well. I have found tremendous results with the CVS brand of diphenhydramine as a sleep aid. It has surprisingly worked better than prescribed medicines.
Hope this helps!
I'm having same problem I've tested for ampthenmines and I don't take I was take benadryl and norvasc I'm like idk wth is going on man and its still coming up in my urine I'm in a mdone clinic there looking into it.
Yes it could have caused a false positive. Make them send your urine to a lab.
Cps has taken my son, they said I had failed for amphetimine. I hadn't done methim almost 2 years!! How could that be possible? I take diphenhydramine hci 25mg pain reliever pm and diphenhydramine hci 50mg night time sleep aid every night to help me sleep. Could this have been the reason?
