Avoid surgery: Rai is designed to "kill" the thyroid without the need for surgery and surgical complications. The side effects of rai are few and manageable if done properly. Once your thyroid is dead, then you will need to take synthroid, (thyroxine) but that is easy... Much easier than taking antithyroid drugs like methimazole. You need an endocrinologist to guide you through this.

Why do you get with radioactive iodine for hyperthyroidism?

Radiation cures!: A hyperactive thyroid will absorb injected radioactive iodine. This iodine will kill the overactive thyroid cells and stop excess production of thyroid hormone. After treatment you will likely require some degree of thyroid hormone replacement to compensate for the loss of thyroid tissue.

Often medications such as methimazole are used initially and then patients subsequently get radioactive iodine.
