Hello. I'm wondering if anyone can help me please. I have been on thyroxine for many years for underactive Thyroid.
My usual dose has been somewhere between 125 and 175 per day for many years.
A recent blood test has shown my TSH to be 40.
I'm not sure what it is meant to be?
My doc just told me to increase my dose from 125 to 200 per day.
Any help or advice would be appreciated
