I was diagnosed with hypothyroidism two years ago and my dose of Levothyroxine was increased to 100 micrograms per day in January. I had bloods taken yesterday morning at my local surgery and have just looked at results on the NHS app.
TSH 0.02 mlU/L. Lab comment - Normal fT4 with suppressed TSH: su clinical hyperthyroidism
Serum free T3 level
I assume my GP will recommend a reduction in the dose of Levo.
Are there any numbers for FT4 and FT3?
Just the following comment:-
Normal fT4 with suppressed TSH: sub clinical hyperthyroidism.
If on T4 consider review of dose and compliance. If not may reflect non-thyroid illness or early hyperthyroidism so repeat TFTs with ft3.
In which case, yes your GP will almost certainly reduce your levothyroxine. Typically it will be dropped by 25mcg daily, so down from 100mcg to 75mcg.
If you feel well on your current dose, you could ask your GP if you can drop to 75mcg on alternate days only i.e. 75mcg one day and 100mcg the next. That would give an effective daily dose of 88mcg, which may work for you.
Assuming you feel well and not over treated….I would refuse to reduce dose until had FULL thyroid testing including Ft3 and vitamin D, folate, B12 and ferritin
Recommended that all thyroid blood tests early morning, ideally just before 9am, only drink water between waking and test and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
do you always get same brand levothyroxine at each prescription

If GP says " I have to reduce your dose because the guidelines say i can't let you have a below range TSH" .....
The first paragraph in the NICE (NHS) Thyroid Disease, Assessment and Management guidelines says :
nice.org.uk/guidance/ng145
"Your responsibility
The recommendations in this guideline represent the view of NICE, arrived at after careful consideration of the evidence available. When exercising their judgement, professionals and practitioners are expected to take this guideline fully into account, alongside the individual needs, preferences and values of their patients or the people using their service. It is not mandatory to apply the recommendations, and the guideline does not override the responsibility to make decisions appropriate to the circumstances of the individual, in consultation with them and their families and carers or guardian. "
Just testing TSH is totally inadequate
INSIST on testing Ft4, Ft3 and all four vitamins before considering reducing dose
If Ft3 is over range….then a small dose reduction eg 12.5mcg 4 days per week…..retest in 10 weeks
