I have MS and Hashimoto's thyroiditis. I have experienced 6 mos of hives in the past after taking antibiotics. That was ten years ago. November of 2016 I began having hives again. I also take serotonin meds which I have heard may play a role in chronic urticaria. I know the two auto immune diseases are related to the hives. Other than applying Arian oil, which stops them from itching (because its anti inflammatory). I have also used topical cortico-steroids occasionally. About every two weeks I am needing a course of prednisone, which I don't want to continue, for obvious reasons.
I went to an allergist and he just switched me from Claritin to Zyrtec. This did not help. I looked it up and saw that taking up to four times the usual dose of Zyrtec is recommended for chronic urticaria. The article also recommended Singulair which I am now taking. Still with the hives! Any recommendations?
