Hi I have recently been told to take a higher dose of Levothyroxine from 100 to 125 as i had usual low thyroid symptoms tired all the time falling asleep etc...and my TSH was 4.9 just above the range of the lab.Doctor said i was under medicated. So taking the new dose feeling really really low, tearful and depressed and appear to have put ON weight in a very short space of time. I've been taking the dose for about a week. Is this a typical reaction of a higher dose i haven't experienced this reaction before when the dose has been raised. Also feel sick every morning but i have been dealing with that I started taking thyroxine 5 years ago. They don't measure the T4 at my surgery but i had it done recently with Blue horizon and the T4 was 18, vitamin D low B12 well within range and Ferritin low. I am taking Iron and Vit D.
Any ideas gratefully received.
