I am having antioxidant tablets will give relief from urticaria, what to do?

Managing unexplained urticaria is often a matter of trial and error -- perhaps even an elimination diet -- and often no solution is ever found. Read up on it, whether it's a subtype like cholinergic urticaria, and let your next try at a Rx be guided by real science.
