I took 75mg of Benadryl 12 hours prior to taking a urine drug screen. will this give drug give me a positive drug result?
Hi. No, benadryl will not give a false positive on a drug screen and the medication itself is not tested for, so no worries here, you'll be negative on the test

are you sure because I have read that it will show a false positive for benzodiazpam

No, not with a standard gas chromography/mass spectrometry test which is done on all samples--that rules out any false positives. That said, just document that you took the benadryl before you take the test
