My condition was mild. I took methimazole 5 mg. for 2 years, and everything was fine. After 2 months off the pills, the lab test was fine. However, 4 months later without pills, the lab test was below normal again. My doctor suggested RAI, but I didn’t want to. I’m afraid after RAI, I might become hypo. He said I could take the pills again if I prefer, but the problem is when I am off the pills, my condition won’t stay normal. Any suggestions?
What is the risk of having RAI?
