I was suffered from itching since last few years but after taking cetrizine tablet in every 4th day it got controlled but since last few days it become uncontrollable and I visit a dermatologist and he ask for a ige total test and my ige total obtained test value if 516.6 iu/ml. Which is very high. Please suggest what should I do because the doctor whom I visit is out of town for next few days and I need relief asap from itching.
