In brief: Many meds for hives

H2 blockers are easy and inexpensive to try and they do sometimes help with treating chronic urticaria.
They include cimetidine, ranitidine, Famotidine and nizatidine. They are all available over the counter without a prescription. In my experience, they rarely work well by themselves, but sometimes work well along with a good h1 blocker, like Cetirizine or fexofenadine. Use an allergist for help.
