T4 Tablet 25 mcg contains Levothyroxine Sodium, a synthetic thyroid hormone used for the treatment of hypothyroidism. It replaces or supplements the natural thyroid hormone thyroxine (T4) when the thyroid gland does not produce sufficient amounts. This helps restore normal metabolism, energy levels, and overall physiological balance in the body.

Mechanism of Action
Levothyroxine is a synthetic form of thyroxine (T4), which is converted in the body into the active hormone triiodothyronine (T3). It binds to thyroid hormone receptors in cells and regulates metabolic activity, protein synthesis, and energy production. This helps normalize heart rate, digestion, temperature regulation, and overall metabolism.
