Forest laboratories make Armour, Thyrolar and Levothroid. Reading the article entitled "Does Forest Really Want to Save Natural Thyroid?" by Mary Shomon, it's obvious that Levothroid is Forest's drug of choice. Must be as cheap as chips to make Levothroid IMO.
"Forest's synthetic T4/T3 medication is unavailable/backordered/no return date, and Forest's natural T4/T3 medication is unavailable/backordered/no return date.
The Thyrolar shortage is blamed on a nonexistent USP issue, and the Armour shortage is blamed on a mysterious "shortage" of raw material that has never been explained. Neither explanation holds up, in my opinion.
Interestingly, Forest's levothyroxine drug Levothroid has no problems with availability and backorders."
"And Forest has never marketed Armour or Thyrolar, won't defend these products, and won't even mention them at their corporate websites. Fact is, they barely acknowledge their existence."
I have no idea how the FDA works, or why Forest made the change. All I can tell you is that I used Armour Thyroid both before the change and after. I can tell there is a difference if you try to take it sublingually, and perhaps that is the biggest reason patients don't like it as well. Other than that aspect I am very happy with it.
The blame may not be Forest itself. FDA and pork products are a big political arena.
There are over 185 products that come from pig- by products
and the medicine for Thyroid is a small market compared to others.

My doctor told me to chew the pills before swallowing them. That seems to help. How do you take yours?
