I’ve been taking thyroxine for 22 years

[Notebook63]

My levothyroxine med went from 75mcg to 100mcg recently so had a blood test and the TSH result said I’m 0.10 so am I now at risk of becoming overactive? Also can thyroid problems cause itchy neck and sweating in bed?

Hi, I take 100mg Levo and my TSH is 0.11 - yes it's under range but doesn't mean I am over medicated. Do you have any other blood results - FT4 and FT3 with ranges?. How do you feel on the higher dose of Levo?

Thanks for reply yes I’ll talk to GP I see him in 2 weeks

You cannot become overactive but can be over medicated . To know if you are overmedicated you need to know FT4 and FT3 results in their ranges but GPs unlikely to oblige so test pricately.

Does English studies carry out tests on Ft’s?

No idea what you are on about.Look at Thyroid UK for information.

Just testing TSH when on Levothyroxine is completely inadequate

As per my replies in previous post

You need FULL Thyroid and vitamin testing 6-8 weeks after any dose (or brand) change in Levothyroxine

Low vitamin levels are extremely common and frequently need supplementing to maintain optimal levels

Thanks i actually did have vitamin B test and vitamin D testing about 2 months ago and the GP said I’m not deficient but I take b12 supplements anyway along with cod liver oil and vitamin c every day

ALWAYS get actual results and ranges

GP would say anything within range is fine

But we need vitamin levels optimal

Folate at least over ten (range usually starts around 3)

Vitamin D at least around 80nmol and around 100nmol may be better. But GP would say anything over 50nmol is ok

Ferritin at least half way in range
