There is no such thing as “the nemesis of hypothyroidism”. Hypothyroidism should be treated with regular medication. Commonly used medications are as follows: 1. Sodium levothyroxine: The purpose of using sodium levothyroxine is to restore serum thyroid hormone levels and thyroid stimulating hormone to normal, and it is usually necessary to take the drug for life. The dose of treatment depends on age, weight, condition, and individual differences. 2. Iodothyronine: fast acting, used for hypothyroidism caused by thyroid hormone resistance syndrome or peripheral thyroid hormone metabolism disorders, also used as an inhibitor of thyroid function tests. 3. Hydrocortisone: need to be injected intravenously, used for mucous edema coma. Hypothyroidism patients with symptoms, need to go to the hospital as soon as possible, by the doctor according to the specific conditions, to develop individualized diagnosis and treatment plan, in order to avoid delays in the condition.
