i am having acute urticaria since 2weeks. i was admitted in a hospital for 4days and was on steroids. after that now i am on atarax 25mg and defza 6mg (1 each a day). But since last two days the hives have started coming back again and its getting extreme. i have consulted my doctor, he asked to take 2 defza a day. Please suggest what should be done, how long does this disease last and how can i get well at the earliest because its really frustrating. Thanks in advance.
