I did not have any break through symptoms after I had RAI. I was on a combination of anti-thyroid meds and lorazepam from the time of diagnosis to RAI which was approximately 12 weeks. The anti-thyroid meds had an adverse effect on my liver and I believe my storms were severe enough to warrant the fast turn-around to receive RAI. My doc had me hold onto the Lorazepam just in case, but I had no break through symptoms after my body settled from the RAI.
I understand why you are anxious about this. It is very difficult to get past the anxiety after you have experienced your body being taken over by these symptoms. I cannot of course guarantee that you will have the same results immediately post RAI, but hopefully you’ll feel a bit more at ease knowing a little more about what I experienced.
