Levothyroxine is a synthetic version of the hormone Thyroxine which is normally produced by your thyroid gland to regulate the body’s energy and metabolism. Levothyroxine is given when the thyroid does not produce enough Thyroxine on its own.
Levothyroxine treats hypothyroidism (low thyroid hormone). Levothyroxine is also used to treat or prevent goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer.
