I have Hoshimotos Thyroiditis and constantly have to have my levels checked almost every six or up to 12 weeks. I have just last month gone and trying to recover from hyperactive toxicosis. Prior to that my TSH was 6.99 since Oct of last year. This time my T3 and T4 were off possibly because of Zoloft, but recently changed to Lexapro. I have the Thyroid Diet book and The Thyroid Source book.
I know prednisone causes problems for my hoshimotos. If I have an MRI with IVP iodine I have to premedicate with prednisone since I’m allergic to the IVP iodine. It’s a constant rollercoaster. If you feel your levels aren’t right push the issue. None of this just have it checked just every six months like they prefer.
