Heart Disease. Heart, or cardiovascular, disease is responsible for nearly half of all deaths in the United States each year, killing nearly one million people each year, and afflicting over 60 million others.
In adults, thyroid hormones help to maintain the function of the brain, the use of food by the body, and body temperature. The FDA approved liothyronine in May 1956. PRESCRIBED FOR: Liothyronine is used to treat hypothyroidism (low production of thyroid hormone) in adults and children. Prolonged hypothyroidism can result in a condition called myxedema in which patients develop swollen lips, thickened nose, and unusual deposits of material in the skin that are dry and waxy.
What is levothyroxine (Levothroid, Levoxyl, Synthroid, Tirosint, Unithroid)? Levothyroxine is a replacement for a hormone that is normally produced by your thyroid gland to regulate the body's energy and metabolism. Levothyroxine is given when the thyroid does not produce enough of this hormone on its own. Levothyroxine treats hypothyroidism (low thyroid hormone). Levothyroxine is also used to treat or prevent goiter (enlarged thyroid gland), which can be caused by hormone imbalances, radiation treatment, surgery, or cancer.
