L-Thyroxine (T4) is a synthetic form of the natural thyroid hormone thyroxine, essential for regulating metabolism, energy production, growth, and hormonal balance. It is widely used to treat hypothyroidism, a condition where the thyroid gland does not produce enough hormones, helping restore normal thyroid function and alleviate symptoms like fatigue, weight gain, cold intolerance, and depression. It may also be prescribed for goiter management, thyroid hormone replacement after surgery, or thyroid cancer treatment. L-Thyroxine works by supplementing or replacing deficient thyroid hormone, ensuring optimal metabolic function.
