pruritus
"So for as long as I can remember I have had severe, chronic itching all over my body. Every day like clock work I start feeling the tingles under my skin and then a non stop itch fest. I was put on Hydroxyzine about 12 years ago and I'm now taking 200 mg every day. It does control the horrible itching for at least 5 hours. I have become so immune to it that it doesn't make me super drowsy any more however, it does make me feel very tired. I wish there was a better alternative but your standard allergy medicines do nothing for me."
