This category includes cretinism, myxedema, and ordinary hypothyroidism in patients of any age (children, adults, the elderly), or state (including pregnancy); primary hypothyroidism resulting from functional deficiency, primary atrophy, partial or total absence of thyroid gland, or the effects of surgery, radiation, or drugs, with or without the presence of goiter; and secondary (pituitary), or tertiary (hypothalamic) hypothyroidism (See WARNINGS).

    2. As pituitary TSH suppressants, in the treatment or prevention of various types of euthyroid goiters, including thyroid nodules, subacute or chronic lymphocytic thyroiditis (Hashimoto’s), multinodular goiter, and in the management of thyroid cancer.

Endocrinologist A doctor who specializes in treating hormone-related disorders
Hyperthyroidism Excessive thyroid gland activity
Hypothyroidism Deficient thyroid gland activity
Levothyroxine sodium (T4) A hormone medication taken by mouth for replacement therapy in patients with reduced or absent thyroid function
Liothyronine The synthetic form of the thyroid hormone triiodothyronine (T3)
L-triiodothyronine A key thyroid hormone that is made from T4 and is the more biologically
active hormone
Myxedema Severe form of hypothyroidism that can be life-threatening
Thyrotoxicosis High levels of thyroid hormone in the blood
Thyroxine Iodine-containing hormone produced by the thyroid gland, also known as
levothyroxine (T4)
TRH Thyrotropin-releasing hormone. TRH is released by the hypothalamus and increases production of TSH by the pituitary
TSH Thyroid-stimulating hormone. TSH is produced by the pituitary and tells your thyroid gland to produce hormone. A TSH blood test is used to determine how the thyroid gland is working
Your body uses T4 to make T3.

IMPORTANT RISK INFORMATION

Thyroid hormones, including ARMOUR THYROID, should not be used either alone or in combination with other drugs for the treatment of obesity or weight loss. In patients with normal thyroid levels, doses of ARMOUR THYROID used daily for hormone replacement are not helpful for weight loss. Larger doses may result in serious or even life-threatening events, especially when used in combination with certain other drugs used to reduce appetite.

WHAT IS ARMOUR® THYROID?

ARMOUR THYROID (thyroid tablets, USP) is a prescription medicine that is used to treat a condition called hypothyroidism from any cause, except for cases of temporary hypothyroidism, which is usually associated with an inflammation of the thyroid (thyroiditis). It is meant to replace or supplement a hormone that is usually made by your thyroid gland.

ARMOUR THYROID is also used in the treatment and prevention of normal functioning thyroid goiters, such as thyroid nodules, Hashimoto’s thyroiditis, multinodular goiter, and in the management of thyroid cancer.

  • Do not use ARMOUR THYROID if you have hyperthyroidism, overactive thyroid, uncorrected adrenal problems, or are allergic to any of its ingredients.
  • Tell your doctor about any other medical conditions you may have, especially heart disease, diabetes, blood clotting problems, and adrenal or pituitary gland problems.
