Levothyroxine is a thyroid hormone medication used to replace the lack of thyroid hormone available in your body. It is used to treat the following indications:

•    Hypothyroidism, a medical condition that causes the thyroid gland to secrete a lower than normal amount of thyroid hormone. The function of thyroid hormone is to regulate your metabolism. Symptoms of hypothyroidism include: cold intolerance, muscle pain, hair loss, deep voice, fatigue, weight gain, and dry, flaky skin.

•    Tumors that respond to TSH (parathyroid tumor type).

Do not take levothyroxine

•    If you are allergic to levothyroxine, or any other ingredients this medication contains. Tell your doctor about the symptoms you experience.

•    If you have uncorrected adrenal insufficiency (underactive adrenal glands in your kidneys).
