Liothyronine: functions, dosage, side effects, how to use

What Drug Liothyronine?

What is liothyronine for?

Liothyronine is used to treat an underactive thyroid (hypothyroidism). This drug replaces the hormone normally produced by the thyroid gland. Low thyroid levels can occur naturally or when the thyroid gland is injured by radiation / drugs or removed by surgery. It is important to have appropriate thyroid hormone levels in the bloodstream in order to maintain normal mental and physical activity. This drug is also used to decrease thyroid function in certain diseases such as when the thyroid gland is enlarged (goiter) and Hashimoto's thyroiditis. This drug is also used to test thyroid activity. Liothyronine is a man-made hormone that can replace the body's natural thyroid hormone (T3).
