Armour Thyroid is made from porcine thyroid glands. Only USDA
inspected grain-fed pigs are used.
Since Armour Thyroid is made to replace thyroid hormones,
the most common side effects generally mimic an underactive or overactive thyroid
(hypothyroidism or hyperthyroidism, respectively). Adverse reactions other than
those indicative of hyperthyroidism, either initially or during the maintenance
phase, are rare.
If you experience chest pain, increased pulse rate, palpitations,
excessive sweating, heat intolerance, or nervousness, please consult your doctor
immediately; your dose may need to be adjusted.
