Hashimoto’s thyroiditis and hyperthyroidism are more serious compared to primary hyperthyroidism, mainly from the treatment point of view of primary hyperthyroidism, the treatment time is longer, and easy to relapse, in the process of oral antithyroid medication is also prone to liver function damage and leukopenia. Many patients with Hashimoto’s thyroiditis don’t need oral medication if they don’t have combined hypothyroidism. Some patients have primary hypothyroidism due to Hashimoto’s thyroiditis, and the treatment is relatively simple: patients need to take Eugenol every day as a replacement therapy. Euthyrox is relatively safe and has fewer side effects. Thyroid function should be reviewed once a month, and if the dose of Euthyrox is appropriate and the thyroid function is normal afterward, there is no need to review it every day.
