anxiety
""Atarax" was prescribed to me in a "controlled environment." I was prescribed Klonopin originally, but the 0.5mg dosage wasn't enough for my anxiety and with the medication (Suboxone) I was currently taking there is a risk of taking Benzodiazepines while on Suboxone (like, death). 
Anyway, Atarax was prescribed. I can't remember the dose now, I know it was more than 10mg, but it was 4-6 x daily as needed. It seemed to be working alright at first, but I think it was the controlled environment, when I left, it stopped working for my anxiety and panic attacks and has not had any useful effect since.
*Didn't experience any side effects"
