Hi,
I could see making a case for this post on three boards actually but since the goal is to use the thyroid hormones as antidepressant augmentation, then I think the strongest case is for the main board also.
But since we're already here...
That's interesting that you've had such a negative response to T3. I was under the impression that it was more useful against depression than T4. If I understand you correctly, you think that in your case the problem has to do with the conversion rate? I've never tried T3 on its own (only as part of Armour thyroid) but neither the T4 nor the Armour have made much of a difference in terms of anti-depression for me so far. Perhaps if I raise the T4 dosage it will help.Your TSH is definitely on the high side. I probably couldn't hurt to bring it down a bit. I didn't know that T4 had some direct effects also.

My experience with thyroid hormone prescribed specifically for depression yielded a better response to T4 than to T3. It might depend on whether or not there is an impairment in the body's rate of coversion of T4 -> T3. T3 worsened my depression tremendously, despite multiple challenges. I might have to press my doctor to give T4 another try. My latest TSH was over 4.0.

(How long will it take before the medical establishment readjusts these maximums downward?????) Anyway, I told the doctor that I'm always cold (not to mention quite depressed). He said he wouldn't change my dosage since I was in the normal range. I've been treating my own thyroid condition in the recent past so I could always try adding a little more to the prescription I was given in hopes of getting more energy and a decrease in depression. I've read that between .5 - 1.0 is a more ideal TSH for those of us with depression. I've been taking 50 mcg of T4. I'm considering adding a little Cytomel or just increasing the T4 a little bit. The fact that I'm taking a small amount of doxepin has me thinking that maybe I should stick with the T4 (I've read in a few places that T3 can increase the cardiotoxicity of the tricyclic antidepressants.) What do you think?
