Thinking about changing my dosages. What do you think?

Your advice will be appreciated.

I am thinking I could increase my Eltroxin and decrease my Thybon 20 Henning.

My results since March have been:

16.03: FT3 4,5pmol/L (2.5-5.7); FT4 14.7 (9.0-23.0); TSH >0.01 (3.0-4.0)

01/06: FT3 6.1pmol/L (2.5-5.7); FT4 14.7 (9.0-23.0); TSH >0.01 (3.0-4.0)

I THINK my medication for 16/03 test was as for 01/06 test.

Eltroxin 100mcg/125mcg alternating days; 20mcg Thybon Henning

It changed from 08/07. Medication at 19/08:

Eltroxin 100mcg/125mcg alternating days; 15mcg Thybon Henning

19/08: FT3 4.8pmol/L (2.5-5.7); FT4 14.7 (9.0-23.0); TSH >0.01 (3.0-4.0)

Of course, my GP is in a panic about my TSH and always notes that he is following the advice of my endocrinologist.

I am thinking that I would be better increasing my Eltroxin to 125mcg every day. As a negotiating tool with my endo, I thought I could lower my Thybon Henning to 10mcg. (of course, the Thybon Henning is taken in 3 doses, approx 8 hours apart.

Of course, my GP is in a panic about my TSH and always notes that he is following the advice of my endocrinologist.

If your endo and GP know anything at all about taking T3 then they will know it reduces, even suppresses TSH, it's just what taking T3 does so there's no need to panic about that. What is important is where your FT3 is through it's range, if it's over range you're overmedicated, if it's within range you're not.

Your FT3 of 4.8pmol/L (2.5-5.7) is a very nice 71.87% through range.

Your FT4 of 14.7 (9.0-23.0) is 40.71% through range.

(Calculator: chorobytarczycy.eu/kalkulator )

Both are where one would expect to see them when someone is on combination hormone replacement, along with a low TSH.

How do you feel with these results? If you feel good there is no need to change anything. If you feel symptomatic then you may be like me and need FT4 higher in range. If you lower your dose of T3 then your FT3 level will reduce, and it's low FT3 that causes symptoms.

Thanks for this. I always appreciate your advice. I will talk to my endo about my T4. I would like to try a 125mcg 2 days/100mcg 1day schedule rather than just alternate days as I still feel tired and a bit low.

Not what you're looking for?
