It is unfortunate that you had that reaction and I hope you have recovered! However, I have had reactions to pills prescribed by doctors as well, with not one nurse ever bothering to check a PDR (Physician's Desk Reference). It is my view that we have to be very-well-informed consumers and not let anyone dictate what we do with our lives.

I have been on Synthroid or Levothyroxine now for 22 years and this year I plummeted down into a lie-on-the-couch funk that did not dispel with vitamins or acupuncture or therapy. What did pull me out of it was a product called "Raw Thyroid" (a tissue extract complex of thyroid, adrenal, spleen, thymus and pituitary) and I have no one to advise me on how to take it... it has literally pulled me out of that slump to the point where I can now cook a meal without burning it and get a day's work in. It is very difficult to take because I my doctor (an internist) knows nothing about natural thyroid supplementation. Self-pay visits to one of the "natural" thyroid doctors will cost me $500/$400 a visit plus lab tests plus additional visits-- I can't cover that, so I will take my chances.
