I have been on T3 for several years now. I started on T4 but it made my hypo symptom worse, I had a few months of success with NDT but again it ended up making me more hypo. I was seeing Dr Peatfield at the time (so sad to hear of his passing, he was a wonderful gentleman and doctor) he recommended switching to just T3 . Unfortunately it was just before he retired so I wasn't able to follow up with any further appointments so just carried on taking it.
I'm very hypo at present and also in the Perimenopause which seems to of made things a whole lot worse.
I have visited a private Endo who has suggested I take 25mg of Wockhardt Thyroxine and 12.5mg of T3.
At present I am on 50mg of T3 split throughout out the day.
Has anyone had any experience of going from T3 to T3 and T4 combo?
If I'm not converting T4 to T3 or RT3 is the issue, is there anyway to overcome it?
My recent blood test in June was
FT4 5.5 (9.1 - 17.6)
FT3 3.7 (2.4 - 6.0) It has been as high as 8 not that I have ever felt over dosed.
TSH 0.14 (0.35 - 4.9)
Any advice greatly appreciated .

Do you always test under the same conditions - fasting and at the same time of day with same dose timing pre test?
To see stable levels of T3 its recommended to allow 8-12 hours between last T3 dose & blood test. If taking one dose then the day before split into 3 or 4 doses and take the last one with the correct timing.
So the FT3 is a bit of a false low result but your TSH is far too high.
Timing of your blood test is important. Always try to standardise them by timing last dose of T3 & time of day for blood test, keep them the same each time etc
You have room for an increase of T3 if you wanted to.
If your ferritin is low then it would be worth while working on that depending exactly how low it was? What was the number for it?
Iron is a cofactor for B12, also needed for best use of thyroid hormone.
Is that a joke? I'm sorry, I don't understand. How can 'only just' under range be 'far too high'? What do you think it ought to be? Not that it matters, anyway. That low in someone taking T3, it's totally irrelevant.
I doubt the T3 has stopped working - it's a hormone, not a drug. Hormones don't just stop working. If your last dose of T3 was the recommended 8-12 before the blood draw, it looks more to me like you've stopped absorbing it. Do you always take it on an empty stomach and wait at least an hour before eating or drinking anything other than water? At least two hours away from other medication/supplements?

And you paid good money for that suggestion? That's a tiny dose - especially compared to what you're taking at the moment. I really cannot see how that would help anything - and would probably make things a lot worse. I wouldn't do that if I were you.
I can't tolerate T4, either. I take 75 mcg T3. From time to time, I experiment with adding in some T4, but I still can't tolerate it, and have decided that I will never try again. But, if I were to try again, I would not drop my T3 by such a massive amount. That would just make me ill.
Medichecks and BH also offer private blood draw at clinic near you, or private nurse to your own home…..for an extra fee
I am a bit surprised you still have measurable FT4 levels after years on T3 only. I have read that they are most often undetectable when you take T3 only. Could your own thyroid gland be producing some hormones on its own?
The endo you saw seems absolutely clueless. Is sh/e a diabetes specialist? If you were really overmedicated on T3 (which does not seem to be the case) and reduced it so drastically, you would need a lot more T4 instead, not just 25 mcg.
Hi, I take 60mcg of T3 only a day. I’m surprised by your dosing timetable. I spread mine out more dosing at 6am, 2pm & then before bed usually at about 9pm. If you research you’ll find that T3 doesn’t stay long in the blood. So your doses are too close together leaving you low in the evening & particularly overnight. I think I’m right in saying that naturally T3 peaks at night.
Also be aware that high T3 can cause high blood sugar especially first thing in the morning. By concentrating your dose early in the day you maybe causing less than ideal higher blood sugar levels.
I think your thyroid must be producing enough T4 to keep you going when your T3 tablet dose has worn off. Personally, I couldn’t manage at all with your dosing timetable. Maybe try spreading your doses more evenly through the day. You may well feel better.
