Help with results

I was taking 75 thyroxine and 20 T3 split into 2 doses in January when I saw consultant - results were:

TSH 0.08 (range 0.3 - 4.2)

FT3 5.3 (range 3.1 - 6.8)

FT4 14.1 (range 12 - 22)

He told me to increase thyroxine to 100 plus 20 T3 - results 6 weeks later:

TSH 0.02

FT3 6.7

FT4 17.5

Was contacted by surgery to advise that GP needs to see me asap because of latest results - I am beginning to panic a bit myself as I am scared that FT3 may go over now on the dose I am taking. Does anyone know if I need to cut down on the T3 or the thyroxine. Any advice appreciated.

No need to panic, FT3 is within range. If it tips over range at your next test reducing Levothyroxine by 12.5mcg should drop it back into range. Y

our results on 100mcg T4 + 20mcg T3 are excellent. I imagine your GP is faffing about the suppressed TSH. There's no need to worry about it. Insist your GP gets your endocrinologist's approval before adjusting your medication.
