SHYTOMEL 25 (25mcg Liothyronine)

Product Information

Shytomel (Liothyronine) is a thyroid hormone used to treat conditions caused by low levels of thyroid hormone (hypothyroidism). It may also be used to treat or prevent goiter (an enlarged thyroid gland).

Liothyronine works by restoring the body’s natural thyroid hormone levels, helping to regulate energy, metabolism, and growth. It is prescribed when the thyroid does not produce enough hormone on its own.
