I was started on Tapazole (generic) 5 mg three times a day for Graves Disease.(I apparently have antibodies for both Hashimoto's and Graves and was initially mildly hypothyroid). My tachycardia and anxiety went away on the medication and I was feeling well. After about 4 weeks on the med, I developed generalized hives which required an antihistamine and prednisone to resolve. Currently I am not on any treatment for my Graves (it has been about two weeks) and my heart rate is beginning to increase (90's) and my anxiety is coming back. I was told propranolol is not an option for me because when I occasionally get bronchitis, I have mild reactive airway disease with it. My doctor is recommending radioablation, but I would like to use that as an absolute last resort. Is there any other medication that would be safe to try such as PTU or anything else? Also, how do you know when it is absolutely necessary to go to radioablation...i.e. heart rate etc.
Is there anything I can use to control the anxiety in the meantime? Thank you for your kind help.
