Levothyroxine is a medication used to treat an underactive thyroid gland (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. This hormone is important for maintaining normal energy levels and metabolism.
It is important to take levothyroxine exactly as prescribed by your doctor and to follow their instructions carefully. Do not stop taking this medication without consulting your doctor, as it may lead to negative health effects.
Consult your healthcare provider for more information about levothyroxine and how it can benefit your health.
Medical Uses
Levothyroxine is a synthetic form of the thyroid hormone thyroxine that is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. It is also used to prevent goiter, a condition characterized by an enlarged thyroid gland, and to treat thyroid cancer.
Hypothyroidism: Levothyroxine is commonly prescribed to patients with hypothyroidism to restore their thyroid hormone levels to normal. Symptoms of hypothyroidism include fatigue, weight gain, cold intolerance, and depression.
Goiter: Levothyroxine can help shrink an enlarged thyroid gland and reduce symptoms such as difficulty swallowing or breathing.
Thyroid Cancer: In some cases, levothyroxine may be used as part of the treatment plan for thyroid cancer to suppress the growth of cancer cells and prevent recurrence.
