Cytomel 25mcg 2 x 100 tablets (liothyronine)
How Cytomel (liothyronine) works
Cytomel (liothyronine) is a synthetic version of the T3 thyroid hormone made by your thyroid gland. Thyroid hormones have important functions like controlling metabolism, body temperature, heart rate, and more. When the amount of hormone is too low, taking thyroid replacement hormones can bring your levels back to normal.
What is Cytomel (liothyronine) used for?
- Thyroid cancer (with radiation and surgery)
- Thyroid suppression test
If you been diagnosed with hypothyroidism, it’s virtually certain that you’ve been prescribed the drug levothyroxine (marketed under the brand names Synthroid, Levoxyl, and others)—a synthetic hormone that replenishes the thyroid hormone thyroxine, also known as T4. But if you are on levothyroxine and still not feeling well, another drug known as Cytomel (liothyronine) may help.
Cytomel is the synthetic form of the hormone triiodothyronine, known as T3, which is equally important to healthy metabolic function. Some endocrinologists also endorse the use of natural desiccated thyroid (NDT), a drug derived from dried glands of pigs or cows that has T3 and T4 along with other thyroid gland protein such as thyroglobulin.
Liothyronine is a man-made form of a hormone that is normally produced by your thyroid gland to regulate the body’s energy and metabolism. Liothyronine is given when the thyroid does not produce enough of this hormone on its own.
Liothyronine treats hypothyroidism (low thyroid hormone). Liothyronine is also given as part of a medical test for thyroid disorders.
Liothyronine is also used together with surgery and radioactive iodine therapy in people with thyroid cancer.
Liothyronine should not be used to treat obesity or weight problems.
Liothyronine may also be used for purposes not listed in this medication guide.
