  • No, I don't think so. Your FT4 is not high, it would be better around 18-19, and most people seem to feel best with a TSH nearer 1. So I think you have room for an increased dose

  • Thank to the doctor next Friday so hopefully theyl do a blood test and ket me stay on the higher dose

  • Don't take your medication on the morning of your blood test and have it as early as possible. Take meds afterwards. This is what Dr Toft of the British Thyroid Association says:-

    The appropriate dose of levothyroxine is that which restores euthyroidism and serum TSH to the lower part of the reference range – 0.2-0.5mU/l.

    In this case, free thyroxine is likely to be in the upper part of its reference range or even slightly elevated – 18-22pmol/l. Most patients will feel well in that circumstance.


    Dr Toft also goes on to say some need a suppressed TSH or the addition of some T3 to a reduced T4.

    If you require a copy of this Pulse Online article, email and give your GP a copy highlighting question 6.

  • shaws thanks, pls could louise Warville email me a copy of the pulse article pls email to me at

  • Hi minus

    You have to email and she will send you the Pulse article.

  • Well done Audrey, for standing your ground!

    As Harry says, if you feel you need to up your dose, there some room for manoeuvre with those results. It would be good to have a T3 result too, to see what the T4 is doing - you may like to think about having a full private thyroid test once you've stabilised on your new dose.

  • Thanks for that i definately will have full blood test in a few weeks
