Mode of Action

Levothyroxine is a synthetic form of thyroxine (T4), a hormone naturally produced by the thyroid gland. It is converted into triiodothyronine (T3) in the body, which regulates metabolism, growth, and development. By replacing the deficient hormone in hypothyroidism, levothyroxine helps restore normal metabolic activity.
