Tremors and NDT - is there a connection?

I have been taking NDT since August and my symptoms are steadily improving. I was taking 1 3/4 grains, in three divided doses, until two weeks ago when I developed a tremor in my hands and an internal 'shakiness'. It is worse in the morning and seems to wear off during the day. I reduced my dose to 1 1/2 grains (1 grain at 6 a.m and 1/2 grain at 3 p.m), because I thought I might be overmedicated. My functional practitioner thought the same.These are the latest results from Blue Horizon taken on 8th decemberTSH .04 (.24-4.2)

T4 12.78 (12-22)

T3 4.92 (3.1 - 6.8)

Magnesium 1.13 (.6 1) -a free test from BH.

I am really pleased with these results as my T3 was very low in September. It would appear that I am not over medicated on NDT and the T4 result suggests I don't have reverse T3 issues.

I have been taking Citalopram since August and am on 20 mg. A tremor is listed as a side effect, but I would have thought this would have appeared earlier. I plan to come off this as soon as I can, now the T3 levels are increasing.

I am taking 800 mg daily magnesium glycinate, for high cortisol, which is why the magnesium result is high, so will stop this.

I obviously want to increase the NDT as there is room for improvment with the T3 levels and I am still far from being well. I'll stay on the 1 1/2 grains for a few more weeks, see what the tremor does and then think about increasing.

Any views, ideas would be greatly appreciated.

Thanks, Shaws. I'd love to be able to take my NDT all in one go, but it doesn't work for me, so I have to take divided doses. I'll try splitting the 1 grain into two divided doses and see if that works.



You aren't biochemically over medicated on NDT so perhaps the tremors are a side effect of the Citalopram. Side effects can develop, they don't necessarily become evident as soon as you start taking a medication.


Thanks Clutter, I think I might reduce the Citalopram to 15 and see how it affects the tremor.


Did you find the cause of the tremours.

I have had them for 2 weeks and it's driving me mad.


Hi Donna, the tremors went after I stopped taking Adreset, which I was taking for high cortisol. Cortisol is still high, but I am taking Ashwaghanda. I am also on a higher dose of NDT than I was then. I have stopped the Citalopram too, so that helped. It is never easy is it, a bit of a guessing game.
