Since being on T3 (6.25mcg) for 2 months I've noticed that my recent blood test showed my FT3 at 3.9 (4.0 - 6.8). Still under-range. Before when I was on Levo only it was 3.7. Not a big increase. As the recent blood test was taken over 24 hours after my last meds could this small increase in FT3 be the result of the T3 having left my body after such a long gap?
I am now taking 10mcg of Lyothyronine split into two doses and 62.25mcg of Levo and based on the above results I can't see my FT3 levels rising very much. Would it be too much to add another 5mcg in two weeks time or wait until the next blood test which won't be until October. Incidentally, my FT4 is 17.3 (12.0 - 22.0) TSH 0.67 (0.27 - 4.20).
Just out of curiosity which is the stronger Tiromel or Lyothyronine? Thank you for your response.
