Welcome to the forum, Lei4.

You appear to be optimally dosed on 75mcg Levothyroxine and 10mcg T3. Isn't your GP prescribing it?


Thankyou no my endo was



Why has endo stopped prescribing it?


Thankyou my current endo didn't think it was improving my symptoms even though I felt better on it but the endo I had before (she now works in London and I live in south west UK) believed it was helping me and she was happy for me to stay on it



Spare me endos who don't believe patients and impose their own damn prejudices about treatment! On top of that your numpty GP has reduced dose because TSH is low presumably?

If your endo is a registrar you could write to the consultant endo and complain about being taken of T3 which you benefitted from in the hope the prescription is reinstated.

Thankyou yes GP reduced dose despite endo saying the levels actually looked good



Contact your endo and ask endo to tell GP that you need 75mcg not 50mcg and to stop interfering. What point is there in patient's seeing specialists if GPs ignore their treatment plan and interfere?



Why was your dose reduced from 150mcg to 50mcg? Dose changes should be done gradually, usually 25mcg at a time, not reducing by 100mcg at all once.

Your August results do not show that you are overmedicated. Yes, your TSH is suppressed, but your FT4 is in range, as is your FT3, but your FT3 is low and shows you need the T3 that was removed.

By removing your T3 and reducing your Levo by such a large amount, you've now been plunged into hypothyroidism again and it's very likely that your nutrient levels have been affected. So you need to test

Vit D




Iron Panel

Full Blood Count

Also, have you had thyroid antibodies tested, were they positive, do you have Hashimoto's which is very often the case when we see posts like yours.

I agree with Clutter, that when you were on 75mcg Levo plus 10mcg T3 your results looked good, how did you feel and why were you changed to 150mcg Levo only?


Thankyou I felt much better on 75mcg levothyroxine and 10mcg T3 and GP then intervened and reduced dose to 50mcg



If you are under the care of an endo your GP shouldn't interfere. Can you contact your endo?


No idea what to do, endo didn't like me taking T3 and surprised me when he said my levels on 150mcg looked very good and they were the levels my GP didn't like
