Most side effects happen when the dose is too high and can feel like an overactive thyroid. Contact your prescriber if symptoms are new or worsening.

Armour Thyroid Key Facts
What Armour Thyroid is
A natural thyroid hormone preparation (desiccated thyroid extract) that contains both T4 (levothyroxine) and T3 (liothyronine). Each “grain” provides 38 mcg T4 and 9 mcg T3.
What it’s used for
Thyroid hormone replacement or supplemental therapy for hypothyroidism (most causes)
In select cases, to suppress pituitary TSH for certain thyroid conditions, such as some goiters or thyroid cancer management
How it works
It replaces thyroid hormones your body normally makes. Thyroid hormones affect energy use, metabolism, and many organ systems, so the dose needs to be carefully individualized and monitored.
Armour Thyroid Safety Overview
Armour Thyroid is a thyroid hormone medicine. Dosing of this medication needs to be individualized and monitored with labs.
Armour Thyroid Warnings & Precautions
The main safety issue is getting the correct dose. Too much thyroid hormone can cause serious heart and “overactive thyroid” symptoms.
Important safety warnings:
- Thyroid hormones should not be used to treat obesity or for weight loss in people with normal thyroid function.
- Too much thyroid hormone can strain the heart (fast heartbeat, palpitations, chest pain), especially in older adults or people with heart disease.
- There’s a small margin between “not enough” and “too much,” so lab monitoring and dose adjustments are important.
- The active ingredient is animal-derived; the manufacturer notes a potential (theoretical) contamination risk cannot be fully ruled out, and no cases of disease transmission have been reported.
Do not use Armour Thyroid if:
- Uncorrected adrenal cortical insufficiency
- Untreated thyrotoxicosis
- Known hypersensitivity to ingredients
Side Effects and When to Get Help
Hyperthyroidism (high dosage):
- Rapid or irregular heartbeat, palpitations
- Shakiness, anxiety, sweating, heat intolerance
- Diarrhea, weight loss, trouble sleeping
Get urgent help right away if you have:
- Chest pain, fainting, severe shortness of breath
- Very fast or irregular heartbeat
- Severe or sudden worsening symptoms
Interactions
Most interaction issues come from absorption changes or from thyroid levels shifting other medicines’ effects. Keep a consistent routine, and review every new prescription or supplement with your prescriber.
Interactions to review with your prescriber may include:
- Blood thinners like warfarin since thyroid hormone can increase anticoagulant effect in some patients
- Diabetes medicines since thyroid replacement can change insulin or oral medication needs
- Estrogen therapy or estrogen-containing birth control since thyroid dose needs can change
- Supplements that affect absorption such as iron or calcium products since they may need spacing from thyroid dosing
