Hi, I have been taking 25mcgs levothyroxine for 6 and a half weeks now and my previous results from 24th November 2023 were:
TSH 4.18 (0.27-4.2)
T4 12.7 (12-22)
My latest results are
TSH 4.36 (0.27-4.2)
T4 14.1 (12-22)
So my TSH has gone up - which seems strange. I did try taking 50mcgs for a few days over Christmas but got heart palpitations and have also had Covid so went back to 25mcgs.
Anyone experienced something similar? Could this indicate that I am a poor converter? GP does not test T3 and havent been able to get done privately due to being unwell. thank you

If symptoms of hypothyroidism persist despite normalisation of TSH, the dose of levothyroxine can be titrated further to place the TSH in the lower part of the reference range or even slightly below (i.e., TSH: 0.1–2.0 mU/L), but avoiding TSH < 0.1 mU/L. Use of alternate day dosing of different levothyroxine strengths may be needed to achieve this (e.g., 100 mcg for 4 days; 125 mcg for 3 days weekly).
I take Vencamil which only come in 100mgs so been cutting it into 4. I take it in the morning - tried taking it at night but found it kept me awake and more heart palpitations. Will try adding half of a 25mcgs for 2-3 weeks before going to 50mcgs, I think that will work for me.
Due to get vitamins retested when I get over covid - have been taking all the supplements that im low in since last September so levels should be good. Thanks SlowDragon.
Think of it as your thyroid has been struggling, and along comes a pill and the body says "oh, I dont have to work so hard" so your TSH goes up. All this is doing is signalling that your body says "more please". Low T3 can cause heart palpitations, so it may be wise to ask for your GP to "check my T3 because of my heart". They probably wont though.
As other wiser heads have suggested, go up gradually. I hope you feel better soon.
