hello everyone
I’ve recently had my meds upped to 100 from 75 mcg Teva but the 100 mcg are smaller in size than the 75 mcg..just wondering if they just look different but are stronger …I’m not sure how I feel as only had them four days now…has anyone else noticed this..I will ring the pharmacist tomorrow ..thanks Carol.
It is not unusual for the size of tablets to change in unpredictable ways.
It might help to remember that only around one thousandth of your tablet is actually levothyroxine! A tablet might weigh 100 milligrams. Which is 100,000 micrograms. But your dose is only 100 micrograms.
In the USA, where they usually have a large range of dosages, it is common for every tablet to be exactly the same size, regardless the dosage.
One UK make, the 25 was the physically largest tablet.
Does the tablet have 100 on one side and a score on the other? I have tried to include physical details (where known) in my UK medicine document. But I do not know the diameter of Teva tablets.
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. There is now a specific world desiccated thyroid document.
I highly recommend viewing on a computer screen, or a decent sized tablet, rather than a phone. Even I find it less than satisfactory trying to view them on my phone.
helvella - Thyroid Hormone Medicines - UK
The UK document contains up-to-date versions of the Summary Matrixes for levothyroxine tablets, oral solutions and also liothyronine available in the UK. Includes injectables and descriptions of tablet markings which allow identification. Latest updates include all declared ingredients for all UK products and links to Patient Information Leaflets, etc. PLUS how to write prescriptions in Appendix F.

oh thanks for answering so quickly..I did another post as I realised both tablets were from different manufacturers. The 100 mcg tabs have a C on one side and TC on the other , thanks Carol
I recently switched to Teva and was thinking their tablets were massive compared to almus. Lol
Be aware …….Many people find Levothyroxine brands are not interchangeable.
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,
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
July 2024
Crescent levothyroxine. Dosages: 12.5, 25, 50, 75, 100
(Not yet known if all approved dosages are or will be available).
Excipients: lactose monohydrate, maize starch, croscarmellose sodium, gelatin and magnesium stearate.
Lactose free brands - currently Teva or Vencamil only
Teva makes 25mcg, 50mcg, 75mcg and 100mcg
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
But for some people (usually if lactose intolerant, Teva is by far the best option)
Vencamil (currently 100mcg only) is lactose free and mannitol free. 25mcg and 50mcg tablets hopefully available from summer 2024
March 2023 - Aristo now called Vencamil

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.

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).

Thanks for the info
Yes I am on 75mg and 100mg alternative days and the 75mg is a larger tablet. Packing in the tablet presumably but a pharmacist should be able to explain.
Thankyou
what brand do you take please
CarolMSM It varies, currently 75 Crescent Oharma Ltd, 100 Accord. 100 is usually one strip of 14 and 75 a cut strip (14 from 28).
Increased anxiety…
Menopaused. Would starting HRT mean reducing NDT? Has anyone experience of this please?
I’m fine. Really?
Thyroidectomy or not? Thyroidmegaly and multi modular goiter. 
which levothyroxine brands are made in 75 mcg?
