We typically don't use thyroid medication to suppress thyroid nodules or cysts, unless the patient has a high risk history of radiation to the neck or family history of thyroid cancer. If the TSH level is elevated then of course we use thyroid hormone to bring it back to the normal range. Palpitations are a common side effect of thyroid hormone treatment, but often they resolve in the first 2 weeks of being on the medication. It may be an indication that the dose is too high for you.
Thanks very much for your response, will see how things go in the next week or so. much appreciated
thank you for your response re: the palpitations. that's what happens to me every time i try a dosage of levo -- within a few days i get heart palpitations -- even on as low a dosage as 12.5
needless to say, it's very frustrating.
Hi Dr Lupo, I need your advice again. My TSH is 0.02 now after being placed on 75mcg levothyroxine over 2 weeks ago to try to shrink (or "suppress") an elarged multinodular thyroid (I have only half a thyroid now after having a hemithyroidectomy last March to remove my large and multinodular left side of the thyroid). Before i went on the medication my level was about 0.76. My endo said the medication should "switch off" the thyroid and help it shrink. However I am concerned about seeing such a low TSH, my doctor said as long as the FT4 and FT3 stay in the normal range i am ok, however my FT4 is borderline high already at 23.5 (limit is 24) and has climbed from a level of 14.5 in my last test in November, my FT3 is ok at 5.5 (limit is 6.5).
Are there dangers with having such a low TSH? I heard having an extremely low TSH can be bad for the heart and bones in the long run. But does this apply if my FT4 and FT3 are ok? And what about using this type of suppression treatment? I hear it's controversial.
