Advice please. I have been on levothyroxine 50mg for 8weeks. Most recent blood test came back TSH 3.05 (0.27-4.2), free thyroxine 15.7 (12-22). Gp has refused to increase Levi to 75mg. He believes things are going in the right direction and will continue to improve. Endocrinologist asked for TSH to be between 2-3. I continue to be easily fatigued and have been having repeated viral infections. What do you all think?? Has anyone any evidence that I could take to gp to convince him an increase would be helpful?
