I've been taking Levothyroxine for the past 11 months. My TSH was 7.2 (0.30-4.2) & my FT4 was 11.5 (12.00-22.00).
After almost 8 weeks on 50mcg my TSH went down to 2.8, range as above. My FT4 was not tested this time.
After a further 8 weeks on the same dose my TSH was 2.6 and my FT4 was 14.9.
My GP agreed to increase the Levo to 75mcg and when I tested next after 8 weeks my TSH was at 1.1.
I have now been taking 75mcg for just over 5 months. I decided to do a medichecks home test this week to see how things are doing & I got the following results:
TSH 2.41 (0.27-4.20)
FT4 16.5 (12.00-22.00)
FT3 4.36 (3.10-6.80)
Are there any obvious reasons at to why my TSH has risen? I have taken my blood tests at the same time, fasting, drinking only water.
I have been supplementing B12, B complex & iron for the past 11 months as these were low.
I can't see that I'm doing anything differently but I'm not getting the same results from my current dose. Is this normal? Can anyone help?
I was tested for TPO antibodies last December & these came back negative.
