I'm on prescribed 100mcg T4 and 20mcg T3. My endo is "concerned" about my suppressed TSH, but is continuing to prescribe at the current dose because I am clearly extremely well. How long this will continue I don't know, because the chief endo is on record as saying that he will not tolerate suppressed TSH. Sooooo, does anyone know how long I would have to be off T3 to get a TSH that is "in range"? How quickly does TSH respond? I know at least one patient stays off T3 for two weeks - is this necessary?
Latest test results: TSH under 0.03 (0.35 - 5.5) FT4 14 ( 10 - 19.8) FT3 4.4 ( 3.5 - 6.5) BTW, I have perfect housekeeping in terms of gluten free, vitamin levels etc.
I already avoid taking T3 for 15 hours prior to testing to avoid "scaring" my endo and GP with the spike after dosing. I have told my endo this and although surprised, he thinks it is actually an idea that is worth continuing with.
Interested in any info at all. Thank you.
