I’ve recently had an appointment with a consultant who finally diagnosed hashimotos and also confirmed my thyroid is still slightly enlarged. Also that my t3 to t3 conversion isn’t so good.
He’s moved me from 150mg levo to 100mg levo + 30mg NDT (erfa) as he said that would effectively be the same dose.
Would I expect to feel different on an equivalent dose? And how long would it take to feel different? I’m hoping I will at the very least feel more energetic
Whatever we've been prescribed to replace thyroid hormones is to try to alleviate any clinical symptoms we may have.
Your Endo sounds a good one as he's prescribed a combination dose.
You have to give a few weeks at least to judge whether or not the dose is suitable.
T3 saturates all of our T3 receptor cells (and is also the 'active thyroid hormone' and then sends out 'waves' throughout the day. Levo (T4) has to change to T3 but not everyone finds levo suitable for them. The brain and heart have the most T3 receptor cells.
How long is a piece of string? It's different for everyone. And, what you are now taking is just a tiny dose of T3 - 4.5 mcg - so might not be enough to make you feel different at all. How long have you been taking it? Did your endo say anything about increasing the NDT with time?
Hi thanks for this. Since last Friday so not long at all. Things are so frantic at the moment work wise and I’m shattered - so sometimes when I’m in that state I don’t always notice a step change in how I feel, and I guess after years of levo and changes to that I never really feel that great, unless it’s reduced and then I feel horrific . He didn’t mention increasing but will see me again in 6 weeks to see how things are progressing.
OK, so probably not long enough to feel any difference. I have to say that some people feel better almost immediately, but other it can take weeks. And, don't worry if you start to feel better, and then feel bad again. This is normal and it just means you're ready for an increase in dose. 
Thanks - fingers crossed then and when things settle down I might get an opportunity to reflect on how I’m feeling
I’m just so grateful to try something different. He’s prescribed t3 before but is a lot more comfortable with ndt as it doesn’t create a spike.
Not sure he's right on that one, but still. Glad you're getting to try something different.
I don’t know so much about either aside from what I’ve read on here - but for some reason he wanted to use Ndt but he has prescribed t3 before according to the endo list .
Were vitamin D, folate, ferritin and B12 levels tested
Levels should be tested at least annually
Vitamin D twice a year when supplementing
What vitamin supplements are you currently taking
As you have Hashimoto’s are you on strictly gluten free diet or dairy free diet
Hi yes I’ve had testing on vit d which was pretty abysmal at 31! He’s got me on 4000 per day. Folate on nhs was 6.2 but I’m not sure of the range
Healthscreen - Ferritin - 92 (range 13-150)
Healthscree. - B12 - 107 (range25-165)
Interestingly the nhs reads of ferritin and b12 wee lower but they didn’t tell me the ranges.
And I’ve not been reducing dairy, but have significantly reduced carbs generally
How long does it take for T3 (NDT) to be eliminated from the body?
How long before I feel better after switching from T4 to NDT?
How long does it take NDT to work 
How long to feel better?
How long after quitting NDT would I be back to baseline?
