Used primarily in the treatment of hyperthyroidism, this compound helps reduce the production of thyroid hormones by inhibiting the enzyme involved in their synthesis. It is effective in managing symptoms of overactive thyroid, such as rapid heartbeat, weight loss, and anxiety. Due to its mechanism, it allows for control of thyroid hormone levels, making it useful in preparing patients for thyroid surgery or radioactive iodine therapy. Regular monitoring is required during use because of potential side effects affecting the liver or blood cell counts.
