Liothyronine

Liothyronine is a synthetic form of the thyroid hormone triiodothyronine (T3). It is commonly prescribed to treat an underactive thyroid (hypothyroidism) and certain thyroid-related conditions. Liothyronine helps maintain normal metabolism, energy levels, and body temperature by replacing the hormone that the thyroid gland fails to produce. It is especially useful in cases where T3 replacement is preferred over T4 or when rapid hormonal correction is needed. Always use this medicine under medical supervision.

Uses of Liothyronine

• Treatment of hypothyroidism (underactive thyroid)
• Management of myxedema coma (severe hypothyroidism)
• Thyroid hormone suppression therapy in thyroid cancer
• Used during diagnostic testing of thyroid function
• As a replacement therapy for low T3 levels

How Liothyronine works

Liothyronine works by replacing or supplementing the T3 hormone in the body, which is normally produced by the thyroid gland. It regulates metabolism, energy, heart rate, and body temperature by influencing how cells use energy. This helps improve symptoms of an underactive thyroid.
