Hashimoto's thyroiditis
Hypothyroidism caused by Hashimoto's thyroiditis is treated with thyroid hormone replacement agents such as levothyroxine, triiodothyronine, or desiccated thyroid extract. A tablet taken once a day generally keeps the thyroid hormone levels normal. In most cases, the treatment needs to be taken for the rest of the person's life. If hypothyroidism is caused by Hashimoto's thyroiditis, the TSH levels may be recommended to be kept under 3.0 mIU/l.
