I have slight hyperthyroidism which at this level doesn’t require treatment just regular blood tests,so do I now stop supplementing with T3 or should I cut the tablet into 4?
Also,my TPO is 35.
Could you space the text a bit better or put each test on a separate line? Its very difficult to pick out the relevant numbers.
Who said you have 'slight hyperthyroidism'? If you're taking T3 it means you must have hypothyroidism, and taking T3 will make your TSH low/suppressed. That does not mean you have hyperthyroidism. And you certainly should not be treated for hyperthyroidism.
If you are taking T3, look at your FT3 result. It is not much more than mid-range, which certainly doesn't indicate over-medication, much less hyperthyroidism. So, if your doctor told you that, he knows nothing about thyroid or how to treat it. 
monitor your health who did the blood test
Overall comment07/06/2023Your results indicate you may have a mild form of overactive thyroid known as subclinical-hyperthyroidism. This normally does not need treating at this stage, but indicates you should have your thyroid hormone levels checked regularly in the future. We recommend repeating this test in 3 to 6 months.
That is just a general lab comment , made on the assumption that you are not already diagnosed with a thyroid problem , and are not taking any replacement thyroid hormone .. it's not based on your individual circumstances .
You are taking thyroid hormone for treating hypothyroidism , so that comment should be ignored. its not relevant to you.
TSH will often be below range/ or even supressed when taking T3 .Some GP's would say the low TSH means you are overmedicated and should reduce your dose a bit ... but others would say that if you feel well ,and have no symptoms of overmedication , then the low TSH when taking T3 is not a problem as long as the T4 and T3 are not over range.
Note* Hyperthyroidism/ Overmedication are a bit different:
Hyperthyroidism is the thyroid making too much T4 /T3 by itself, continuously .
Overmedication is taking too high a dose of replacement T4/T3 , no treatment is needed , the dose is simply adjusted.
The symptoms are the same for both , and are the result of too much T4/T3 .. but the cause and treatment are different.
p.s . To know if the fT3 result is accurate it's important to let us know how long a gap you left from the last dose of T3 to taking this test ..
should be no longer than 8-12 hrs from last dose T3
and 24 hrs from last dose Levo
.
It was 24 hours after both meds.
Hello Shell ;
What do you mean by slight hyperthyroidism -
do you have symptoms of hyperthyroidism or are you saying this based on these blood test results ?
Once diagnosed hypothyroid you can't become hyperthyroid - though you could become over medicated.
Your results, the free T3 and Free T4 are both in the range and do not read as overmedicated.
I see you are experimenting with adding in some T3 - Liothyronine and this may well have suppressed your TSH reading :
What strength of T3 tablet and brand are you taking and or proposing to stop or chop into smaller pieces ?
We really need more information to help you better :
Hi Pennyannie, I have been taking Tiromel 25mcg cut in half so 12.5 and I have felt a lot better, shall I continue at that dose then.
Shell -
Without your sharing more information with forum members it's impossible to say anything of any value :
What was the reason for your diagnosis of hypothyroidism - do you have Hashimoto's - an auto immune thyroid disease - are you with or without a thyroid ?
What dose of T4 are you taking ?
What was the time line from your last dose of T3 and your last dose of T4 to the blood draw ?
Do you have a TSH, Free T3 and Free T4 reading prior to starting this experiment ?
Shell when we are hypo and take T3 then many find that their TSH is low. That is how things are.
It does not mean that you are hyper or overmedicated.
When you are on T3 you need to look at your hormone levels Ft3 and ft4 and how you feel.
An easier to read way of presenting your results...
07/06/2023
FT3 5.6 pmol/L (3.1 - 6.8 pmol/L)
FT4 16.2 pmol/L (12 - 22 pmol/L)
TSH 0.04 mu/L (0.27 - 4.2 mU/L)
Note :
Triiodothyronine is another name for T3. FT3 is short for Free T3.
Thyroxine is another name for T4. FT4 is short for Free T4.
Thyroid Stimulating Hormone is the full name for TSH.
Also :
Your Free T3 is 68% of the way through the range.
Your Free T4 is 42% of the way through the range.
How much levothyroxine are you currently taking
Which brand
Ft4 is rather low ….you probably need small increase in levothyroxine
But GP will likely only look at low TSH
Day before test split T3 into 2 or 3 smaller doses spread through the day …..with last dose T3 Approx 8-12 hours before test
So next test - cut T3 into 1/4’s (use sharp craft scalpel)
1/4 tablet waking and 1/4 tablet around 9pm
previous post shows terrible ferritin level
healthunlocked.com/thyroidu...
Low ferritin will make you feel exhausted and lower TSH
I’m on 75mg of levothyroxine and not sure what brand as I get it pouched. I have got an appointment with Endocrinologist on the 16th due to my brain haemorrhage being close to the pituitary gland and not being checked in the first 12 months.
You can always identify the make of levothyroxine by looking at the tablets - and any markings on them
I think all UK ones are adequately described in my UK medicines document.
helvella's medicines documents (UK and Rest of the World) can be found here:
helvella - Thyroid Hormone Medicines
helvella has created, and tries to maintain, documents containing details of all thyroid hormone medicines in the UK and, in less detail, many others around the world.
This link takes you to a page which has direct links to the documents from Dropbox and Google Drive, and QR codes to make it easy to access from phones.
The UK document contains up-to-date versions of the Summary Matrix for tablets, oral solutions and liothyronine available in the UK.
if it’s a single tablet it will be Teva brand as they are only brand that makes 75mcg tablets
Do you always take levothyroxine on it’s own on empty stomach and then nothing apart from water for at least an hour after
No vitamins or other medication within 2 hours
No iron, calcium, vitamin D or magnesium within 4 hours of levothyroxine
Most easily available (and often most easily tolerated) are Mercury Pharma or Accord
Mercury Pharma make 25mcg, 50mcg and 100mcg tablets
Mercury Pharma also boxed as Eltroxin. Both often listed by company name on pharmacy database - Advanz
Accord only make 50mcg and 100mcg tablets
Accord is also boxed as Almus via Boots,
Many patients do NOT get on well with Teva brand of Levothyroxine.
Teva is lactose free. But Teva contains mannitol as a filler instead of lactose, which seems to be possible cause of problems. Mannitol seems to upset many people, it changes gut biome
Teva is the only brand that makes 75mcg tablet.
So if avoiding Teva for 75mcg dose ask for 25mcg to add to 50mcg or just extra 50mcg tablets to cut in half
But for some people (usually if lactose intolerant, Teva is by far the best option)
Aristo (currently 100mcg only) is lactose free and mannitol free.
March 2023 - Aristo now called Vencamil

Wockhardt is very well tolerated, but only available in 25mcg tablets. Some people remain on Wockhardt, taking their daily dose as a number of tablets

Once you find a brand that suits you, best to make sure to only get that one at each prescription.
Watch out for brand change when dose is increased or at repeat prescription.
Government guidelines for GP in support of patients if you find it difficult/impossible to change brands
gov.uk/drug-safety-update/l...
If a patient reports persistent symptoms when switching between different levothyroxine tablet formulations, consider consistently prescribing a specific product known to be well tolerated by the patient.
academic.oup.com/jcem/artic...
Physicians should: 1) alert patients that preparations may be switched at the pharmacy; 2) encourage patients to ask to remain on the same preparation at every pharmacy refill; and 3) make sure patients understand the need to have their TSH retested and the potential for dosing readjusted every time their LT4 preparation is switched (18).
Discussed here too

Levothyroxine is an extremely fussy hormone and should always be taken on an empty stomach and then nothing apart from water for at least an hour after
Many people take Levothyroxine soon after waking, but it may be more convenient and perhaps more effective taken at bedtime
verywellhealth.com/best-tim...
No other medication or supplements at same as Levothyroxine, leave at least 2 hour gap.
Some like iron, calcium, magnesium, HRT, omeprazole or vitamin D should be four hours away
(Time gap doesn't apply to Vitamin D mouth spray)
If you normally take levothyroxine at bedtime/in night ...adjust timings as follows prior to blood test
If testing Monday morning, delay Saturday evening dose levothyroxine until Sunday morning. Delay Sunday evening dose levothyroxine until after blood test on Monday morning. Take Monday evening dose levothyroxine as per normal
