I started on levothyroxine 50mg in feb22 as I was reallly unwell my TSH then was 35.4 it lowered to 7 then rose to 10 so I went on 75mg followed by 100mg my recent blood test at the beginning of may gave me 0.07 TSH and T4 was 21.1 at this point I was told I’d gone overactive and reduced back to 50mg weekdays and 100mg weekends I’m really confused and just so hungry and tired and suffering really bad depression and anxiety any advice would be massively appreciated thankyou for reading .

I am sorry you are going through this. That is a massive decrease. No wonder you feel so awful. There are others more knowledgeable than I to answer your questions, but it doesn't appear that you were overdosed.
Hi .. that last reduction sounds like it was much bigger than necessary .( unless you actually had symptoms of overmedication)
Once taking thyroid hormones the thyroid doesn't become 'overactive '. (the thyroid is 'on holiday') but we can become 'overmedicated' if we take too much . ( same symptoms as overactive / hyperthyroid, but not same cause .. i do wish doctors would use the proper term ,, telling people they have 'gone overactive' just confuses the issue)
You current dose is 64mcg /day ([50 x 5] + [100 x 2] = 450 , divided by 7 )
dropping from 100mcg to 64mcg is a huge drop in dose.
once you are somewhere near the right dose , adjustments should really be as small as possible. not brutally chopped in half just because the TSH is slightly low .
it would probably have been more sensible for GP to reduce dose to to 87.5mcg ( 75 / 100 mcg alternate days).
or perhaps to 75mcg day , depending on whether the fT4 was high in range , or over range.
Do you have the lab range for that fT4 test ? eg [12-22] or [7.9 -14] or [9-21] etc
You are legally entitled to printed copies of your blood test results and ranges.
The best way to get access to current and historic blood test results is to register for online access to your medical record and blood test results
UK GP practices are supposed to offer everyone online access for blood test results. Ring and ask if this is available and apply to do so if possible, if it is you may need "enhanced access" to see blood results.
Always test thyroid early morning, ideally just before 9am and last dose levothyroxine 24 hours before test
This gives highest TSH and lowest Ft4 results
You’re only over medicated if Ft3 is over range
Ft3 not even been tested
Never agree to dose reduction without FULL thyroid and vitamin testing
GP has most likely reduced dose far too drastically
How long since you reduced dose
Bloods should be retested 6-8 weeks after each dose change or brand change in levothyroxine
Do you always get same brand of levothyroxine at each prescription
For full Thyroid evaluation you need TSH, FT4 and FT3 tested
Also both TPO and TG thyroid antibodies tested at least once
Very important to test vitamin D, folate, ferritin and B12 at least once year minimum and ESPECIALLY after dose reduction in levothyroxine as vitamin levels likely to reduce
About 90% of primary hypothyroidism is autoimmune thyroid disease, usually diagnosed by high thyroid antibodies
Autoimmune thyroid disease with goitre is Hashimoto’s
Autoimmune thyroid disease without goitre is Ord’s thyroiditis.
Both are autoimmune and generally called Hashimoto’s.
Low vitamin levels are extremely common when hypothyroid, especially with autoimmune thyroid disease (Hashimoto’s or Ord’s thyroiditis)
20% of autoimmune thyroid patients never have high thyroid antibodies and ultrasound scan of thyroid can get diagnosis
In U.K. medics hardly ever refer to autoimmune thyroid disease as Hashimoto’s (or Ord’s thyroiditis)
Recommended that all thyroid blood tests early morning, ideally just before 9am and last dose levothyroxine 24 hours before test
This gives highest TSH, lowest FT4 and most consistent results. (Patient to patient tip)
Private tests are available as NHS currently rarely tests Ft3 or all relevant vitamins
