What is liothyronine?
Liothyronine is a naturally occurring hormone produced by the thyroid. It is important for
normal energy and metabolism. For a variety of reasons, the body may not produce enough of this
hormone on its own. In these cases, liothyronine is taken to replace the body's natural thyroid
hormone.
Liothyronine is used to treat hypothyroidism (low thyroid function). Liothyronine is also
used to prevent and treat goiter (growth or enlargement of the thyroid gland). Causes of goiter
include hormonal imbalances, radiation, surgery, and cancer.
Liothyronine may also be used for purposes other than those listed in this medication guide.
What should I discuss with my healthcare provider before taking liothyronine?
Since thyroid hormone occurs naturally in your body, almost anyone can take this drug. In
general, liothyronine should not be taken if you have other hormonal problems that are not being
adequately treated.
Before taking this medication, tell your doctor if you have heart diseases such as coronary
artery disease, hypertension, and angina. These conditions may be affected by thyroid therapy, and
closer monitoring may be necessary at the start of therapy.
Changes in blood sugar may also occur in diabetics, and special monitoring may be
necessary.
