Antithyroid Agents

Antithyroid agents are medications used to treat an overactive thyroid gland, also referred to as hyperthyroidism. These medications work by blocking the gland’s ability to release hormones, making it less active. This helps reduce the symptoms of hyperthyroidism, such as weight loss, palpitations (rapid heartbeat), nervousness, irritability, and other signs associated with an overactive thyroid. It can also help reduce inflammation in the thyroid gland, leading to a reduction in the size of the gland. Antithyroid agents can be used alone or in combination with other treatments, depending on the individual’s medical situation. In addition, they can be used as a preventive measure in people with a family history of thyroid disease.
