So many people want to know what is in the different brands of levo, so I prepared this table based on helvella 's useful file. I looked up the ingredients of current brands. I made it for a friend and it seems to make things clearer for me.
Please let me know any errors.

I've now looked up 'sodium starch glycolate type A'. Type A is based on potato. I'm sensitive to potato so that explains why Vencamil disagreed with me. It's also in Armour which also disagreed with me.
Just shows I should have been careful with google!
I'm sensitive to oats and wheat as well as potato, but not gluten. Further googling shows that 'starch glycolates are also of rice, wheat or corn origin' so could be the wheat for me.
Yes it’s on my notes but the pharmacy do occasionally try to slip in Teva which give me terrible headaches. I open my prescription in front of the pharmacist now and if it’s Teva I refuse to accept them.
I do exactly the same, got caught out once as Teva was just in small writing on the side and I was so poorly. Luckily the chemist exchanged them for me as it was their mistake and my prescription said No Teva on it.
The mannitol used in any particular product might well be synthetic.
But mannitol does naturally exist in many plants.
It was originally made from the flowering ash
Natural extraction
Since mannitol is found in a wide variety of natural products, including almost all plants, it can be directly extracted from natural products, rather than chemical or biological syntheses. In fact, in China, isolation from seaweed is the most common form of mannitol production. Mannitol concentrations of plant exudates can range from 20% in seaweeds to 90% in the plane tree. It is a constituent of saw palmetto (Serenoa).
There is no reason to consider that two products with different active pharmaceutical ingredients would be likely to have the same excipients.
Indeed, that is usually unlikely even when they have the same active pharmaceutical ingredients. The exception might be levothyroxine oral solutions which are close to identical.
(And, of course, where the exact same product is supplied under different presentations/liveries - like with AAH Hillcross levothyroxine actually being Teva or Accord depending on dosage.)
helvella - Thyroid Hormone Medicines - UK
The UK document contains up-to-date versions of the Summary Matrixes for levothyroxine tablets, oral solutions and liothyronine available in the UK. Includes injectables and descriptions of tablet markings which allow identification. Latest updates include all declared ingredients for all UK-licensed products and links to Patient Information Leaflets, Dictionary of Medicines and Devices (dm+d), British National Formulary, NHS Drug Tariff, etc. PLUS how to write prescriptions in Appendix F.
Also includes links for anti-thyroid medicines (but not product details).
This is brilliant. Thankyou for taking the time to do it.
I intend to print it off and wave it under the pharmacist's nose next time he tries to palm me off with anything other than what it states on my prescription ie Accord/Almus/Northstar .
I'm sure he thinks I'm just being awkward by refusing to accept all the recognised brands he wants to offload.
I don't think I did until I started looking them up.
That 2nd column - are they all interchangeable? Is Mercury exactly the same as Eltroxin? and Advanz? Same ingredients, but are they in the same proportions?
Yes - they are absolutely 100% identical. This has been explicitly conformed by the MHRA.
(Many years ago, there was a tiny difference in one of their 50 microgram tablets - and the MHRA got them to reformulate to make them identical. Until then, the two 'versions' had different product licence numbers.)
However, we do not have the details to establish if the proportions of the excipients are the same in the 25, 50 and 100 microgram tablets.
I need to ask a question I’m hoping Helvella can answer.
I have to take carbocisteine for a lung condition. It is made by a number of companies but almost all contain yellow dyes eg sunset yellow and quinolone. However Milpharm do not contains these.
BUT I have been told by my usual pharmacy and another, that it is illegal to specify a certain manufacturer. And it is the luck of the draw if the ones I want come in.
The same is so with Sitagliptin for diabetes. This is available without the colours as Januvia. But again the pharmacist cannot specify this.
Nor can they contact the manufacturer/ importer directly.
I get dreadful hives with these dyes.
And my HbA1c is going up and down because I cannot get them consistently
Has anybody found a solution?
Can I buy them privately, if so how?Surely I cannot be the only patient with allergies to excipients.
I am entirely unconvinced that someone with a demonstrable intolerance cannot be either prescribed by brand or with a positive requirement to avoid the problem ingredient(s).
However, we see all too many members who have to jump through ridiculous hoops to achieve that.
And I do not know the formal and complete answer.
Regarding private purchase:
All medicinal forms of carbocisteine are Prescription-only (POM). So you first need to persuade a doctor to prescribe it on a private prescription. The rules about NHS doctors and private prescriptions are a bit odd and I do not know if you can get past that. So you might need a private doctor.
Then, the medicine itself isn't that expensive but you can probably add around £10 per item to the NHS price for dispensing a private prescription. Plus postage, if required.
I suggest you consider contacting Roseway, as their resident prescribing GP might be willing to prescribe especially if you have NHS prescriptions already.

Handling questions about excipients

Pharmaceutical excipients are constituents of a medicine that are not used for their direct therapeutic action, but to aid the manufacturing process, such as to enhance stability or bioavailability.
Patients may want or need to avoid certain pharmaceutical excipient(s) for a number of reasons. Medicines free from specific pharmaceutical excipient(s) may be requested for particular patient groups (e.g. neonates), patients with a severe allergy or with particular cultural or religious beliefs. This document aims to assist healthcare professionals in providing safe, effective and timely answers to support that decision. It outlines the steps involved in checking for the presence or absence of the substance in product information; and provides an explanation of the requirements for information about constituent excipients in the product labelling and patient information leaflet.
That is, they accept that avoidance of some excipients is necessary. They provide some background information. But utterly fail to provide any guidance as to HOW to ensure the avoidance is incorporate in prescribing and dispensing practice other than contacting manufacturers, etc.
Thank you - this is a hornets nest but Lactose removal from Teva in particular alters the bioavailability of the Levothyroxine . If you're on it and ok you need to stick with it. Ireland and the US do not allow switching of brands for patients and it should be that way in the UK . I cannot take Teva or other brands which have a Teva product licence without having an issue with my thyroid. One to be aware of and I'm not lactose intolerant.
