Hi, could I have some advise please as to whether I should reduce to 50mcg or 62.5mcg of Levo?
My last two blood tests show a low TSH and high T3 (most recent below and previous ones on my profile).
TSH .01 mIU/L (.3 - 4.2) -7.4%
Free T4 (fT4) 15.4 pmol/L (9 - 19) 64.0%
Free T3 (fT3) 6.2 pmol/L (3 - 5.4) 133.3%
T4:T3 Ratio 2.484
( I follow all the blood test guidelines on fasting, before 9am etc ).
I have been taking 75mcg Levo for just over a year and have been gradually experiencing more fatigue and anxiety. I initially thought I would need an increase but the tests show otherwise. My weight is a steady 50kg.
My GP suggests that I reduce to 50mcg but I read on here on that that is more of a starter dose - but is it be the right amount for some people?
Or should I ask to reduce to 62.5mcg? If so, is it better to alternative 50 and 75 each day or split a 25 in half and take it with 50? Does anyone know if GPs are happy to do this?
Also my GP always requests 3 months not 6/8 weeks between blood tests. Is this too long to wait, particularly if things aren’t quite right?
Below is GPs text comment.
“I'd like to reduce your thyroxine dose from 75mcg to 50mcg because your T3 is higher and your TSH is lower than last time - which tells me you are on slightly too much thyroxine. Your T4 remains normal. I have sent a prescription to Lloydsdirect so the new dose should come by post. Please can you do a repeat blood test in 3 months. to check the new dose?”
I have a telephone consultation booked with them later this week so any advice would be much appreciated, and is anyone else on just 50 mcg and find that OK?
Thanks
