Product Overview

Armour® Thyroid Tablets Description1,2

Armour Thyroid® (thyroid tablets, USP for oral use) is a desiccated thyroid extract obtained from porcine thyroid glands. On a microgram-for-microgram basis, liothyronine (T3) is approximately four times more potent than levothyroxine (T4). Each grain of thyroid provides about 38 mcg of levothyroxine (T4) and 9 mcg of liothyronine (T3). Armour Thyroid is used in the management of hypothyroidism of any cause and for the treatment or prevention of certain forms of euthyroid goiter.

Mechanism of Action1,2

Thyroid hormones influence the growth and maturation of tissues, increase energy expenditure, and affect the turnover of essentially all substrates. These effects are mediated through control of DNA transcription and, ultimately, protein synthesis. Thyroid hormones play an integral role in both anabolic and catabolic processes and are particularly important to the development of the central nervous system in newborns. They regulate cell differentiation and proliferation, and aid in the myelination of nerves and the development of axonal and dendritic processes in the nervous system. Thyroid hormones, along with somatotropin, are responsible for regulating growth, particularly of bones and teeth.

Signs and symptoms of overdosage1,2

  • Anorexia, nausea, vomiting
  • Palpitations, tachycardia
  • Nervousness, tremors

Contraindications & Precautions1,2

  • Hypersensitivity to any component of the formulation.
  • Use with caution in patients with cardiovascular disease (e.g., angina, arrhythmias).
  • Caution in patients with diabetes mellitus as thyroid hormone can alter glycemic control.
  • Start at lower doses in elderly individuals and titrate slowly.
  • Long-term use may accelerate bone loss, especially in postmenopausal women.
  • Store at controlled room temperature (20°C to 25°C / 68°F to 77°F)
  • Protect from moisture and light
  • Keep in a tightly closed container
