Levothyroxine (Synthroid, Tirosint, Unithroid, Levo-T, Levoxyl) is an FDA-approved thyroid medication that replaces a hormone normally produced by the thyroid gland to regulate the body’s energy and metabolism. It is generally prescribed for people with hypothyroidism (an underactive thyroid gland), and while it has been suggested as a possible treatment for idiopathic hypersomnia, levothyroxine carries potential risks, including the risk of cardiac arrhythmia.
