Which treatment is NOT commonly used for hyperthyroidism?

Corticosteroids are not commonly used as a primary treatment for hyperthyroidism. In the management of hyperthyroidism, the main strategies typically include antithyroid medications, which help to reduce the production of thyroid hormones; radioactive iodine treatment, which destroys overactive thyroid cells; and surgery to remove a portion of or the entire thyroid gland in certain cases.

Corticosteroids may be used in specific situations, such as managing symptoms during a thyroid storm or treating related autoimmune conditions like Graves' disease, but they do not directly address the underlying endocrine dysfunction of hyperthyroidism. As a result, they are not typically a frontline treatment option for this condition.
