Is there a home drug test to test for diphenhydramine o.t.c. abuse? i suspect my husband is abusing it
Very doubtful: There's info here: https://en.wikipedia.org/wiki/Diphenhydramine But, I'm concerned too about your relationship. Suspicion is often as harmful as the behavior in question. Consider Couple's Therapy after a few prep sessions for you alone to learn how to communicate concern w/o blame. A test would do nothing to help resolve any problem. Best wishes 2U2. ...Read more
I took drug test today and it was positive for tca, I regularly take an OTC sleep aid with diphenhydramine. Couldn't have caused the false positive?
"tca"????: did you mean THC (marijuana or cannabis)? TCA medically usually means tricyclic antidepressant, and these are actually chemically similar to benadryl. If all that was done was a SCREENING test, there are lots of potential false positives, and if used for legal purposes, all screening tests should be confirmed with a more sophisticated test, usually gas chromatography/mass spectroscopy. ...Read more

Im on drug court and i want to take a sleep aid because i can't sleep I have a generic sleep aid but it has diphenhydramine hci in it will this make me test positive for anything or will it be ok to take it
The : The answer dr. Johnson provided is correct. There are reports that with very high doses, Diphenhydramine has in rare cases, led to false positive drug screening for benzodiazapines. However, if this were to occur, normally the sample would be retested using a more precise test and that would clear up the confusion. It is reported that it could also trigger a false positive for pcp (but this is also very rare). Diphenhydramine is not a good choice for chronic problems with sleep. If you are in a program that requires drug testing, you might consider skipping the Diphenhydramine and working on sleep hygiene first. ...Read moreSee 1 more doctor answer
Can a 16 year old be taking Advil PM if they can not sleep?. And would it show positive in a drug test?
Look on the fine : print. Anything that says "pm" on it has diphenhydramine aka Unisom aka Benadryl in it. Yes it can cause false positives. Depends on test brand. It's used in pediatrics for allergic reactions, so it's fair to say the general medical population considers it safe *properly dosed* It is mildly habit-forming, but way less than doxylamine. Don't use combo products. Does she need ibuprofen in Advil PM? ...Read moreSee 1 more doctor answer

Shy bladder......: I would suggest you talk to your doctor about evaluating the issue, and if no significant pathology is found (like an enlarged prostate), your doctor can provide you with a generic to whom it may concern letter that you have difficulties voiding on command and/or in front of others. Ask them for a saliva test, or tell them you are willing to give blood for a test. ...Read moreSee 1 more doctor answer
