I've been taking Levothyroxine for the past 5 months (25mcg for the first two weeks &50mcg for the remaining time) I had a blood test in December & my TSH had decreased from 7.2 to 2.8 (0.30-4.20)
I asked my GP for a increase however she wanted me to continue on the same dose for a little longer to see if I would get any further improvement. She also wanted to check my FT4 level.
I had another blood test last week & my TSH is now 2.6 (0.30-4.20). The FT4 was 14.00 (12.00-22.00) My original test in September showed a FT4 of 11.5
She agreed to an increase in Levothyroxine to 75mcg in order to see if I feel better. I have seen some improvement in how I feel since starting treatment but I certainly don't feel great. I've also been addressing my low b12, folate & ferritin thanks to the advice given here.
I'm interested to know if it's normal to see a good reduction in TSH but only an small increase in FT4 when starting on Levothyroxine.
