Hello and welcome! I’m not sure about your timeline (guessing RAI in 2023?), but if there is living thyroid tissue left after RAI, it can regenerate – and hyperthyroidism can definitely recur. Dosing with antithyroid drugs can take some tweaking to find the right dose that will keep your levels normal. Has your doctor tested antibodies? I’m guessing you are overseas (as we use a similar drug, methimazole, here in the USA), but in the USA, it’s recommended that antibodies be tested before withdrawing antithyroid medications. If the antibodies are still raging, hyperthyroidism will eventually recur. Keep an eye on your symptoms, and call your doctor’s office ASAP if you feel the old hypER symptoms coming back.
