Thyroid Hormone Replacement Drugs

The Medications, How to Take Them, T4/T3 Drugs, and Armour Thyroid

Hypothyroidism describes the condition where your thyroid is underactive due to autoimmune Hashimoto's disease, surgical removal of your thyroid gland, a thyroid that has been disabled by radioactive iodine, or other factors such as thyroid-slowing medications. In most cases, hypothyroidism means that you need thyroid hormone replacement treatment, a medication that replaces the missing thyroid hormone that your body is unable to produce on its own.

Thyroid hormone replacement drugs used to treat hypothyroidism include synthetic versions of the thyroid hormone levothyroxine (known as T4.). Levothyroxine drugs include brand names such as Synthroid, Levoxyl, and Tirosint. There is also a synthetic form of triiodothyronine, the T3 hormone, called liothyronine. The brand name is Cytomel. Finally, there is natural desiccated thyroid, sometimes called NDT. These prescription drugs are prepared from the desiccated (dried) thyroid glands of pigs, and are sometimes called porcine thyroid. Brand names for these thyroid drugs include Nature-throid and Armour Thyroid.
