Hello, am recently diagnosed and have been gradually having Levothyroxine increases and tested 3 monthly. Was on 50mg (TSH wa 2; range (0.35-4.94) and felt better than on 25, but still not great so was increased to 75mg 10 weeks ago. Had blood test yesterday (followed all advice on this very knowledgable site; fasted, no morning dose levo and done 830am same as others tests). Results have come back as TSH 0.11 (same range as before so out of their range). Just noticed this morning they have also tested Free T4 (presumably as out of range as this hasn’t normally been done); this is upper end (16.3; range 9-19). I had assumed when I got TSH result I need to go back to 50mg, but if Free T4 is within range is that the case? (Never been sure about the correlation if these 2!) All results were on the NHS app so assume I will get a phone call in next few days but just wondering what anyone’s thoughts were on next steps. I’m happy to reduce if advised; felt great on higher dose initially but have been really tired last few weeks (which I had put down to being busy at work but may be related?)
Thank you in advance 😊
