Thank you moma4faith for providing the FDA website.  I started on Armour Thyroid at age 15 and still using it (age 63) (or did as of one month ago) at the very same dose:  formally known as 3 grains, now known as 180 mg daily. And thank you Jessica for your insights of this shortage may relate to the swine flu vaccine.  I have emailed a compounding pharmacy in Colorado to see if they will honor an out of state script and if so what would the cost be.  My internal med. doc told me she would write a script for any US or Canadian pharmacy and I found one that has 180 mg tabs at a cost of almost $400 for 100 pills.  That seems greedy to me.  This happened to me in the late 1970's and early 80's during which time I gained over 50 pounds.  Then their was a lawsuit against Synthroid and Synthroid lost and Armour was back on the market; supposedly not related????  In the 4 weeks I have taken 150 mg of the generic Synthroid I have not had one normal bowel movement (rocks to water), have been so confused it is affecting my business, gaining weight, sleeping 10-12 hours a day with a 45 minute nap during the day, experienced increased arthritis pain and crave meat.  My female doc assures me she has a lot of knowledge about this issue and disagrees with my wanting T3 but  respects my symptoms and concerns.  Hopefully this will blow over soon as it has in the past; problem is no one will tell you when Armour is back on the shelf. I am fortunate to have insurance coverage thru MerckMedco; they claim no knowledge of any other thyroid product like Armour, refuse to look into it.  My doctor did say that one of her patients has had some luck with taking "Thyroid Support" available at health food stores along with the synthetics so maybe I'll look into that. I'll come back to this blog as I have found it very useful.  Thanks!
