T3 and increased anxiety

[PillJunkie]

My current readings are: T3 4.3 & T4 10.8

My endo increased my T3 drug from 30mcg to 40mcg last week.

I have chronic anxiety, the cause of which, I think, is environmental issues. Then a strange thing happened last night:

I had a dream where I was buying something, but the seller suddenly doubled the price. I felt severe anxiety in my dream. I was aware I was dreaming, but chose not to wake! When I did wake, the anxiety was still there and is still present, but is greatly reduced, as I write this. I just have a knot in my stomach.

Clearly, the anxiety attack was not caused by environmental issues. My endo warned me thatanxiety could be a side effect of the drug.

Has anybody else experienced increased anxiety from the T3 drug, but with a relatively low T3 reading?

Thank you.

Please add ranges in brackets after your results, as these can vary between laboratories. Was TSH also tested?

I need to make adjustments in thyroid medication super slowly, as this causes my anxiety to spike. When adjusting Levothyroxine, I only increase by 12.5mcg until well tolerated and with Liothyronine, 2.5mcg.

Remember to retest levels 6-8 weeks after any increase.

Thanks Buddy195. TSH was 0.01 (0.27 - 4.2). FT3 range (3.1 - 6.8). FT4 range (12 - 22).

Yes, my endo does increase my dose by quite a large amount each time. So, if that's the cause of my anxiety spike it should ease off over time. We retest every six weeks. I am hoping that at their present levels of 20mcg T3 and 200mcg Levo, we should hit optimum levels very soon.

Thank you for your guidance.

your dose changes seem a bit extreme pilljunkie.

large dose changes can make us feel awful.... and trigger anxiety

repeated changes before the body has had time to acclimatise to each change is likely to create chaos in the body (and presumably in the brain too) .

doing both together (making large changes repeatedly) is rather asking for trouble.

your post 28 days ago said this:

" ....I suddenly went from 100mcg Levo and 20mcg T3 to 150 and 30 ,respectively, at the same time, 10 days ago".

you increased T3 from 30mcg to 40mcg last week

the reply above says "20mcg T2 and 200mcg Levo " ?

has levo been increased to 200mcg ?

is 20mcg a typo ? top of this post says your taking 40mcg

i would say your endo/ doctor is making changes far too fast, and far too large.

I agree with above comments. I wrote a post recently on this subject - and my slavishly following the idea that ‘more is better’ when it comes to T3.

You speak of your relatively low levels. I think it’s important to remember though that the journey is as important as the destination - and it’s better to arrive safely at your optimal FT3 level by small dose increases and regular testing.

Edit:

I see your FT3 was 4.3 but I wonder how long you left between taking the last T3 and testing. Another mistake I made (I made many!) when I introduced T3 was to leave 24 hours as I always had done with Levo. This gave me a false ‘low’ and led to my making a real mess of things by adding more T3 when I didn’t really need to.
