I take Hydroxyzine Pamoate 25 mg twice a day, but really doesn't help..I bought me an item that you can put anti-itch cream in and then rub all over my back since I can't reach back there.....that is temporary and only lasts a little while...I've been awakened during the night by the itching and it drives me crazy....ya'll probably know how hard it is to go to sleep and to be awake in the middle of the night is the P I T S ! ! ! !
