Questions & Answers

Side Effects & Adverse Reactions

Drugs with thyroid hormone activity, alone or together with other therapeutic agents, have been used for the treatment of obesity. In euthyroid patients, doses within the range of daily hormonal requirements are ineffective for weight reduction. Larger doses may produce serious or even life-threatening manifestations of toxicity, particularly when given in association with sympathomimetic amines such as those used for their anorectic effects.

The use of thyroid hormones in the therapy of obesity, alone or combined with other drugs, is unjustified and has been shown to be ineffective. Neither is their use justified for the treatment of male or female infertility unless this condition is accompanied by hypothyroidism.

The active ingredient (desiccated natural thyroid) in Armour® Thyroid (thyroid tablets, USP) is derived from porcine (pig) thyroid glands of pigs processed for human food consumption and is produced at a facility that also handles bovine (cow) tissues from animals processed for human food consumption. As a result, a potential risk of product contamination with porcine and bovine viral or other adventitious agents cannot be ruled out. Forest is not aware of any cases of disease transmission associated with the use of Armour Thyroid.
