The best approach for you depends on your age, physical condition, the underlying cause of the hyperthyroidism, personal preference and the severity of your disorder: 1  Radioactive iodine. 2  Anti-thyroid medications. 3  Beta blockers.  Surgery (thyroidectomy). If you're pregnant or otherwise can't tolerate anti-thyroid drugs and don't want to or can't have radioactive iodine therapy, you may be a candidate for thyroid surgery, although this is an option in only a few cases. In a thyroidectomy, your doctor removes most of your thyroid gland.
