Armour Thyroid recently went thru a reformulation that is causing many people to be undertreated. Not only that, but there is a shortage of the base ingredients, meaning that even if you had a doctor who would write for Armour, you may not get it. People are even having trouble finding *any* natural dessicated Thyroid.

I would strongly suspect your increased TSH to the reformulated Armour. Hope you can find the right meds.

I had my Armour refill and after about 2 weeks, I thought I was starting to lose my mind. I had already noticed that it smelled and tasted different. I then found out about the reformulation and had my doctor re-write my Rx for NatureThroid. I got that filled and feel miles better — but even that Rx will be difficult to get refilled due to the shortage. My mail order Pharmacy has already informed me of the shortage and suggested that Levothyroxine was a good substitute – NOT!!
