What is Levoxyl?

Levoxyl is a thyroid medicine that replaces a hormone normally produced by your thyroid gland to regulate the body's energy and metabolism. Levothyroxine is given when your thyroid does not produce enough of this hormone on its own.

Levoxyl is a prescription medicine used to treat hypothyroidism (low thyroid hormone).

Levoxyl is also used to treat or prevent goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer.

Levoxyl is also used in patients who need surgery and radioiodine therapy to manage a type of thyroid cancer called well-differentiated thyroid cancer.
