Armour, Erfa, Thyroid-S etc are all Natural Dessicated Thyroid Hormones.
Levothyroxine is only ever called levothyroxine and it is made by several companies. So that's why we should always check we have the same one each time from the pharmacist.
I just want to recap on your dose(s). You were on two 1/2 grains of Armour with the blood test results of tsh 0.27, free t3 is 3, two half grains of amour a day. Which is 1 grain of Armour daily = approx 100mcg levo.
You are now taking: 50mcg levothyroxine and one half grain of armour 30mg tablet.
No wonder you are puzzled. First of all if we are taking NDT the blood tests cannot be exactly be the same as if we were taking levothyroxine alone. I wonder why doctors are unaware of this phenomenon.
So the doctor has reduced your Armour by 30mcg of Armour (equal to around 50mcg of levo !) and gave you 50mcg of levo?
Your doctor didn't do your Free T4 and your FT3 is at the bottom of the range! It should be towards the upper part of the range not the bottom.
I do wish they would stop messing about with patients' medications according to the computer print out as it is like trying to fit a square peg into a round hole. Impossible. Impossible to get to a level where the patient is clear of clinical symptoms and feels relatively well. or really well.
The purpose of taking replacement thyroid hormones and as you have no thyroid gland at all they should be taking far more care of you. You should be having approximately the same amount of thyroid hormones as if you still had a thyroid gland and that would be an amount that removed your clinical symptoms and you felt well.
I think, due to your low FT3 that you don't have sufficient to saturate your T3 receptor cells. Also will the 50mcg of levo convert to sufficient as no FT4 was taken.
I hope someone will be able to suggest how best to turn this to your
advantage. Your doctor has only looked at your TSH I believe and thus changed your dose because of it. 100mcg of thyroid hormones is not sufficient if you have the lowest FT3 and probably FT4 as well.
