Description

(Desiccated Thyroid Extract, Natural Porcine Origin)

Natural Thyroid Hormone Replacement for Hypothyroidism Management

Armour® Thyroid USP 0.1 mg is a prescription-grade natural desiccated thyroid (NDT) medication derived from porcine thyroid gland, containing both thyroxine (T4) and triiodothyronine (T3) in physiologic ratios. It is indicated for the treatment of hypothyroidism—a condition characterized by an underactive thyroid gland, leading to insufficient hormone production and symptoms such as fatigue, weight gain, cold intolerance, hair thinning, dry skin, and mental fog.

Unlike synthetic levothyroxine (T4-only) medications, Armour Thyroid delivers a full spectrum of thyroid hormones, more closely mimicking the human thyroid output. This may offer improved symptom relief in patients who do not respond optimally to T4-only therapy.

Key Features and Benefits

• Provides both T4 (levothyroxine) and T3 (liothyronine) for a comprehensive hormonal replacement

• Derived from natural porcine thyroid tissue, standardized for potency

• May benefit patients with persistent symptoms on synthetic T4 monotherapy

• Available in multiple strengths for individualized titration

• Manufactured under strict USP standards for consistency and safety

• Supports restoration of metabolic rate, energy, mood, and temperature regulation

What Is Armour Thyroid?

Armour Thyroid USP is a natural, prescription-only thyroid replacement. Each 0.1 mg (100 mcg) tablet contains an equivalent of 16.25 mg of desiccated thyroid standardized to provide:

• Levothyroxine (T4): approximately 38 mcg

• Liothyronine (T3): approximately 9 mcg

The product is free from gluten and does not contain artificial colors or unnecessary fillers, making it suitable for sensitive individuals when prescribed appropriately.

Indications

• Primary hypothyroidism (congenital or acquired)

• Secondary or tertiary hypothyroidism (pituitary or hypothalamic dysfunction)

• Goiter management (benign, non-toxic nodular or multinodular)

• Post-thyroidectomy hormone replacement

• Post-radioiodine therapy

• Adjunct in the management of thyroid suppression therapy in thyroid cancer follow-up (when deemed appropriate)

This medication is not indicated for weight loss in euthyroid patients and should be used only under direct medical supervision.

Mechanism of Action

Armour Thyroid acts by supplementing or replacing endogenous thyroid hormone levels, thereby supporting:

• Basal metabolic rate regulation

• Protein synthesis and oxygen consumption in cells

• Thermogenesis and lipid metabolism

• Cardiovascular responsiveness and mental alertness

• Growth and maturation processes in infants and children

By including both T4 and the more active T3 hormone, Armour Thyroid can exert faster symptom resolution in some individuals compared to synthetic T4-only treatments.

Dosage and Administration

• Initial dosage should be based on TSH levels, age, weight, and comorbidities

• Starting dose for adults typically ranges from 30–60 mg per day (0.05–0.1 mg T4 equivalent)

• Armour Thyroid 0.1 mg (16.25 mg desiccated extract) is commonly used in low and maintenance dosing, or as part of a titrated split regimen

• Dose adjustments should occur every 4–6 weeks based on lab results and clinical symptoms

• Take once daily, preferably in the morning on an empty stomach, at least 30–60 minutes before food or other medications

Monitoring Parameters

• TSH (Thyroid-Stimulating Hormone) every 6–8 weeks until stable

• Free T4 and Free T3 levels (especially in combination therapy)

• Periodic monitoring of cardiovascular status in older adults or those with cardiac history

• Signs of underdosing (fatigue, cold intolerance, weight gain) or overdosing (palpitations, anxiety, weight loss)

Safety and Precautions

• Contraindicated in patients with untreated thyrotoxicosis or adrenal insufficiency

• Use cautiously in patients with cardiovascular disease, diabetes, or osteoporosis

• Not recommended for use in pregnancy unless under endocrinologist guidance; dosage adjustments may be needed

• Do not use for weight loss in the absence of hypothyroidism—serious complications can result

Side effects may include palpitations, nervousness, sweating, insomnia, or weight loss if overdosed. Always use under physician supervision.

Storage and Handling

• Store at 15°–30°C (59°–86°F)

• Keep in tightly sealed container, away from moisture and light

• Keep out of reach of children
