synthetic thyroid hormone used to treat hypothyroidism
Levothyroxine, also known as L-thyroxine or T4, is a synthetic form of the thyroid hormone thyroxine. It is commonly prescribed to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone, leading to symptoms like fatigue, weight gain, and hair loss. By supplementing the body's natural hormone levels, levothyroxine helps restore normal metabolic function and alleviate these symptoms.
