is nothing more than a variation of benadryl
--a non-controlled (in the US), but still PRESCRIPTION antihistamine
that (like benadryl) is sedating.
as added hype--and to give physicians the ability to deny benzos
to those with anxiety issues--hydroxyzine is also often touted as an anti-anxiety med.
if you wanted to you could spin it as an antihistamine, a sleeping pill, an anti-anxiety, an anti-itch med, a sunburn reliever, an anti-emetic (to stop puking), as well as an anti-Parkinson's disease cure.
doesn't change the fact that it's (by and large) a non-abusable, non-addictive totally bullshit, non-drug
-of-abuse. and if you're in the US, it's not even a controlled substance.
Don't sweat it. and if they 'claim' that you pissed dirty, DENY THE HELL OUT OF IT! this will force them to do a GC/MS confirmatory test which (of course) will be negative.
