What is levothyroxine?
Levothyroxine is a prescription medication used to treat thyroid conditions. It is a hormone replacement drug usually prescribed to treat hypothyroidism, a condition in which the body does not produce enough thyroid hormone to properly regulate your metabolism and weight. Levothyroxine may also be prescribed to help treat thyroid cancer.
Hypothyroidism affects almost 5% of the U.S. population. Without the proper amount of thyroid hormone, people with hypothyroidism often suffer from fatigue, poor growth, constipation, weight gain, hair loss, muscle pain, depression, and more.
