In May, 2006, TSH=over 150, FT3 & FT4 very low.
I started taking levothyroxine (Sandoz)and tested again in June, 2006. I had the same readings; nothing changed.
My dosage was doubled, and I was tested again in July, 2006; TSH=34.
Long story short, today my TSH is less than .1 and my FT3 & FT4 are in mid range on a dosage of 100 mcg. I still have symptoms, but I feel sooooo much better.
