Yesterday a patient of mine asked if I was aware of a source of desiccated thyroid produced in Thailand. I was immediately skeptical for a few reasons. Many countries do not have an agency that provides quality control for medications. Whatever the drawbacks to the FDA, it is reassuring to know that for the most part, they have been able to protect citizens in the US from dangerous or defective medications. Many other countries provide similar protection to their population. Unfortunately there are places in the world where potentially dangerous medication is still available without a prescription. Quality control of medication production is also lacking.

My concern is that in some parts of the world, possibly Thailand for example, that a medication like Armour could be made but no qualified individual or agency is available to certify its ingredients or standardization.

Today a well meaning member forwarded their comments on a product called Thyroid S produced in Thailand, which is a supposed substitute for Armour thyroid and is available without a prescription. My reaction is that until we can be certain of the formulation of a medication that the best thing to do is to avoid using it. Perhaps in time someone will be able to provide the necessary information required to evaluate this product but as editor-in-chief of this website I will try to guard our readers against becoming victims of scams and exploitation.

I welcome any information others may have on solid information about Thyroid S or similar compounds being marketed as Armour Thyroid substitutes.
