A few weeks ago I was diagnosed with Graves' disease after a sudden RHR spike (40-50+ bpm). Started on methimazole + a beta-blocker — RHR has actually come down nicely (from the 100s to 67 in about 2 weeks on beta-blocker, which seems to mean the methimazole is working).

Last night I broke out in hives and had to get a steroid. No fever or sore throat, so hopefully not the scarier rare stuff, but wondering — has anyone else had a hive/allergic reaction on methimazole? Did your doctor switch you to a different anti-thyroid med, or was it manageable enough to stay on it?
