T-3

Uses
T-3 tablets (Liothyronine Sodium) are a treatment for patients with hypothyroidism. This is a condition where the body is unable to produce enough thyroid hormone on its own. Liothyronine is a synthetic version of thyronine. Thyronine is important for regulation of energy and metabolism in the body, as well as for cell growth. T-3 tablets (Liothyronine Sodium) can also be prescribed to patients with goiters (an oversized thyroid gland resulting from endocrine disorder).
