Hi again ,still on 50 mcg thyroxine and 20 mcg t3 once a day.

Having fuzzy headache all day.Do not know if it is because I am hypo at present (tsh ove r 7) or my increase from 10 mcg t3 to 20mcg .I have not taken it this morning ,but still have headache.I think I will take t3 tomorrow just 15mcg and raise slowly,or do you think 10 mcg am and 10 mcg pm will help headaches.Really want to stop thyroxine though ,how can I do this any ideas. So at aloss a gp does not know what to do,have to wait till may to see endo.Thanks again everyone.

Susie, Can you have blood tests for TSH, FT4 and FT3 now to see what your levels are on 50mcg T4+20mcg T3? It would help ascertain whether your symptoms are due to undermedication.

I suggested a while back that because you are so sensitive to dose increases that you should be cautious and raise T3 by 5mcg increments. If you've skipped a dose this morning and the headache persists perhaps it is unrelated to T3? You could also try splitting T3 into 2 x10mcg doses 8-12 hours apart to see whether you feel improvement.

If you want to stop thyroxine, you just stop taking it but you will need to raise T3 to compensate.

Thanks Clutter,have only been on raised dose for 2 weeks,due bloods in 4 weeks ,will let you know result.Still got bit of a headache .I will take meds in am but only 15 mcg t3 and raise slowly.Thankyou again


Susie, If the headache was due to raising T3 to 20mcg I think you would have had it within a day or two of raising. if you can stay on your current doses of 50mcg T4 + 20mcg T3 until your blood test in 4 weeks I think you'll get a better idea of where your levels are. Do try split dosing the T3 for a couple of days. If it doesn't improve symptoms then you can go back to once daily dosing.
