I have been on 125mg levo per day since last year. I had serious flu last year which led to low Vit D and B12. I had neurological symptoms then and I still have benign fasciculations. I've been tested by the consultant for autoimmune stuff like PA/Coeliacs but negative for those.
I had been on 150 mg levo for 20+ years prior to this with no obvious problems. During the illness I started taking my medication properly (without food, caffeine etc) and had to drop my dose because I became overmedicated.
Late last year I tried daily doses of 136mg and 139mg because I felt 125mg was too low. I didn't feel good on either of those so stopped.
In agreement with my GP I have just started trying a daily dose of 128.6mg (one day on 150, rest of week on 125) and have felt considerably better in the first week of this regime. We will test again in 6-8 weeks.
I know it can take a while to find the euthyroid point. My previous bloods are below.
Can you advise: the GP is focussed on getting the TSH below 2.0 but as I understand it the profile I'm looking for is FT4 in the third quartile of the range, FT3 near the top of the fourth quartile and TSH low in range - is that correct?
I am also supplementing D3 and B12 which were insufficiently replaced over winter - I was put on 10,000iu for 8 weeks which you guys told me would never do anything, and you were right, my D3 declined.
24/03/17 TESTED AFTER TAKING MORNING LEVO: TSH 2.027 Mu/L [0.34-5.6), FT4 13 pmol/L [8.0-18.0], FT3 5.3pmol/L [3.8-6.0], Vit D 43nmol/L, B12 404ng/L, Folate 12.9ug/L, Ferritin 35ug/L [24-250]
