T3

[mischa]

I've just received my latest blood tests and I find these confusing.

My FT3 level before was 6.1 (3.5 - 6.5) and was on 75mcg of T4 and 30mcg of T3.

I felt very over medicated with anxiety, feeling wired, sweating and headaches  so I reduced my T3 to 25mcg.

However, whilst  still on 30mcg I had another blood test and the results are 5.5 clearly not over-medicated.

If I am not over-medicated on 30mcg what other reasons could cause the over-medicated symptoms? Since reducing those symptoms have gone but I am left feeling very cold.

Mischa,

You can *feel* overmedicated without being biochemically overmedicated.  Not everyone does well with FT3 level high in range.  Perhaps you could halve the 5mcg tablet and try 27.5mcg to see whether it relieves the coldness without making you feel wired and overmedicated.

Thank you Clutter - I will try the 27.5mcg and see how I go.

I mean 2.75mcg

I, myself, would take more notice of my symptoms than the blood tests. It's how we feel that should dictate if the dose is correct and needs adjusted which you did do.

I would have preferred to reduce my dose of T4 rather than the T3

You now feel underdosed so that's what I would do, reduce T4 slightly and go back to 30mcg of T3. It is trial and error.

Thanks Shaws - I'm going to try the small increase of 2.75mcg of T3 for a couple of weeks and see how that goes.  Then if it doesn't work I will reduce the T4 and increase the T3 to 30mcg again and do a blood test again.
