Synthroid (Levothyroxine) is used to treat low thyroid hormone. It is also used to treat or prevent goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer. Levothyroxine is a replacement for a hormone normally produces by your thyroid gland to regulate the body’s energy and metabolism. This medication is prescribed to patients when their thyroid does not produce enough of this hormone on its own.
