I had a thyroidectomy Oct 2013 and I started out on 125 Mcg of Levo and 10 Mcg T3 then my Endo dropped me down to 110 levo, then down to 100 levo with 15 Mcg T3. I started having panic attacks so I stopped the T3 thinking it was making me racy then after three days I was so completely jittery and shaky and I don't know know??? Is it because I stopped my T3.

My Endo lowered my Levo down to 88 Mcg and now I feel fine.

Why am I having this problem, no thyroid and only 88 Mcg of Levo seems so low...I am tired and I have gained 20 lbs in one year, and nothing will take the weight off!

Jillybean, not everyone needs high doses of thyroid replacement after thyroidectomy or RAI. My sister has been on 100mcg T4 since RAI 3 years ago.

I don't think you are optimally medicated though as you are tired and gaining weight. Can you post your thyroid results with lab ref ranges for when you were on 125mcg + 10mcg, 110mcg + 10mcg, 100mcg + 15mcg and 88mcg. Raising 10mcg T3 to 15mcg may have been too much and it may have been better to go back to 10mcg for a while rather than stopping T3 altogether.


I just had my blood drawn today, I will post result as soon as I have them for my 88mcg levo

When I was on the 100 Mcg I was so jittery and panic attacks would just randomly happen..... Now that I have dropped down to 88 Mcg I don't feel anxious at all!


Jillybean, maybe adding 5mcg x 2 T3 would help with the tiredness without causing panic attacks or anxiety. It's out of your blood in 6 hours if it does. Are they testing FT3?
