Hi, I would be very thankful for a little advice. I had a total thyroidectomy in 2010 due to thyroid cancer. Been very unwell ever since - all the usual unpleasant symptoms. Told by my oncologist that I am intolerant to Levothyroxine but he said there is nothing else that I could take. Finally found a private Doctor and am about to start taking Erfa. I am petrified to make the change but feel I have no choice as I feel so unwell on current meds. I take 50mg of T4 and 10mg of T3 which I can just about manage. Any advice on making the changeover please. So badly need the NDT to work. Thanks for reading this post.
