Armour Thyroid, used successfully to treat hypothyroidism for over 100 years, offers patients unique benefits not seen with synthetic thyroid preparations. Forest Labs, which has been the maker of Armour for many decades is about to be merged with Pfizer. Pfizer already manufacturers a synthetic thyroid hormone product, Levoxyl. Pharmaceutical industry dynamics require that in this type of merger the weaker of two competing products, in this case Armour, will be eliminated without hesitation. Without Armour Thyroid the health and well being of many thousands will be jeopardized.
