i d'ont know what i can do, i am desesperate.

I have recently been of a drug caleed apo-hydroxyzine and have had an awfull time with a rash that wants to keep coming back, and, I feel very itchy. With this condition it is very hard to work and someitmes even think rationally as the itch is so dicomfortable, and , distressing. I am on several antihistamines and a few other pills from the doctor but the itch is driving me a little crazy. any suggustions! the ones in my hair, face, chest, back, legs and arms will slowly drive me a little nuts as they are so overwhelming. Help
