Advice please - Just been prescribed 10mg carbimazole

[Zman12]

Hi there ,

I just wanted some advice. I was recently referred to an endocrinologist as I had been having hormone tests due to family history of early menopause and planning for pregnancy etc. my results showed low TSH (<0.02 mouth/L) and when they retested showed high T3 (7.6 pool/L) and low TSH.

I do have some symptoms ( think nails/ hair) palpitations and anxiety, clammy hands. But feel well in myself , sleep well and am very active. Growing up I always thought I just had a fast metabolism, eating a lot and remaining very thin. Although I am now a normal weight at 9.7 stone.

I am really reluctant to take the carbimazole as I’m not a fan of taking medications ( rarely even take paracetomol) often opting for herbal things more.

Just wanted peoples experiences of that medication. I also haven’t had the cause of the hyperthyroidism yet so feel like starting the medication already feels like maybe to soon as the side effects seem quite difficult.

I also wondered whether having been contraception for the last 15 years and only recently coming off it for these hormone tests for early menopause may have effected the results as well.

Anyways would be grateful to hear your thoughts ☺️

thank you

I offer my blog page on the subject of carbimazole.

It doesn't really answer your questions but might be of some help/interest.

A short discussion about Carbimazole primarily focussed on splitting doses but containing some other information.

Welcome to forum. Was your FT4 tested and any thyroid antibodies? (There are several)

Add lab range as vary between labs.

10mg a really low starting dose. Important to check raised levels aren't transient.

Are you TTC? Dr would have recommended to wait until thyroid stable.

I don't think stopping contraception would have caused thyroid issue.

Serum TSH level < 0.02 mlU/L [0.27 - 4.2];

Outside reference range

Serum free T4 level 21.3 pmol/L [11.9 -

21.6]

Serum free triiodothyronine level 7.6 pmol/L [3.1 - 6.8]; Outside reference range

Thanks for your reply. 😀 popped the levels above. Yes they have recommended waiting, but also stated would need to take a different medication anyway as that one can’t be taken in pregnancy. Not actively TTC currently but aware I may not have much time.

think they have done more tests which involve the antibodies today so probably will wait and see what they say ☺️ had tests in April and July both showed similar ish results although the T3 got higher in that time. Yes I saw from others that it’s a very low dose don’t think my results are severe from the looks of things.
