Want to try very low dose of T3 - should I split the dose

I stopped taking 10 mcg T3 with my T4 as I developed atrial fibrillation. But on 100 mcg T4 only I felt not 100%, and my free T3 was low. I have tried reintroducing T3 with a lower dose of T4, but feel that it is now causing heart palpitations. I went from 10 to 5 mcg of T3 in 2 doses but still feel not quite right. Thought I would try the Ken Blanchard approach and take 2.5 mcg T3 with 90 of T4. But should I still split the dose of T3? I have 5 mcg tablets and can split them into two with a pill cutter, but they shatter when trying to split them further. ( I have not yet read his book so don't know what he suggests).

Thanks!

I had severe palpitations when on levo and was forever in and out of A&E/ambulances. I haven't had any since being on T3 only. I have no idea why but it works for me. I've always taken whatever thyroid hormone replacements/combinations once daily.

Sometimes palpitations can be caused by too low a doe as well as too high, so we are in a quandary at times to know what to do for the best. A link which may be helpful.

Hi - not a direct answer, but difficulties in taking t3 can be caused by nutritional deficiencies. I have looked through your previous posts and the last tests I see for these were July 2016 with some of them less than optimum. Might it be time to re-test these to see if there is anything there causing issues? The main relevant ones are vit D, vit B12, folate and ferritin.

Coachv,

Reducing T4 dose may mean you are undermedicated which can cause palpitations as well as being overmedicated. Why not increase Levothyroxine dose to 100mcg plus 2.5mcg T3 x 1 daily.

I believe Dr. Blanchard used compounded T3 in doses of 1.25 - 2.5mcg to treat his patients.

I agree with Clutter . Increase Levo to 100 and add 2.5 mcg T3/NDT in divided doses .I just want to clarify in NDT it's about 16mg .

Clutter you are right . Dr B never went higher then 2.5 mcg of T3 in a time release capsule . And his theory works . But you can make your own time release by dosing 2-3x/day . His theory is 98.5:1.5 ratio . His patients loved him . He had patients from all over the world . He is a tremendous loss for the thyroid world .
