Levothyroxine sodium (Levotiron, T4) is a synthetically manufactured form of the natural thyroid hormone tetraiodothyronine (T-4). Thyroid hormones are primarily responsible for regulating the body's metabolic rate, and play a vital role in the body's utilization of protein, fat, and carbohydrates. Levothyroxine sodium is used medically to treat cases of hypothyroidism, which is characterized by insufficient natural production of thyroid hormones.This may manifest itself with a number of symptoms including loss of energy, lethargy, weight gain, hair loss, and changes in skin texture. Levothyroxine sodium is considered a slow-acting medication, and may take up to 4 to 6 weeks before full therapeutic levels are reached in the blood. It is also the most commonly prescribed thyroid medication in the world, and is considered to be the standard form of treatment for most cases of hypothyroidism.
