What should I do if the symptoms of hyperthyroidism are still obvious after taking iodine for 2 months? 1, after iodine-131 treatment, it starts to work in about 1 month, and feels relieved in 3 months, whether it is cured at once should be judged after half a year, you are currently treated for about 2 months, if the symptoms are obvious, you can take anti-thyroid drugs, liver function impairment while taking liver-protective drugs, after 3 months, you can stop taking the drugs and try, if the symptoms do not appear, maybe the hyperthyroidism has been relieved. 2. This is also normal. When the effect of iodine-131 is not fully developed, some patients will have aggravated symptoms and thus need anti-thyroid medication to control and relieve. 3. Some patients may have aggravation of proptosis or emergence of proptosis after iodine-131 treatment, which is related to elevated autoimmune antibodies and TSH, and can be treated with Yunque. It is now advocated that to prevent aggravation and appearance of proptosis, thyroxine should be taken to inhibit further increase of autoantibodies even when thyroid function is normal. 4. Despite the high rate of iodine uptake by the thyroid, if the effective half-life is too short, 3 milli-curies of iodine-131 may not cure hyperthyroidism. The industry advocates moving closer to 6, 7 or 8 milli-curies for a possible one-time cure, and it is possible that the chances of hypothyroidism will be higher this way, but most hyperthyroid patients get remission. It is highly likely that you will need to be treated again in six months.
