Best Levothyroxine brand + can I chew the tablet?

SKalila profile image
20 Replies

Hi everyone,

I was recently diagnosed with Hashimoto's and have been prescribed Levothyroxine, which I have never taken before. I have done some reading, which gave me the info that people respond differently to different brands. In your experience is there one brand that people prefer over others? Are there any brands that people generally don't get on with?

I have a phobia and anxiety and taking medications increases my anxiety considerably. I have issues swallowing even tiny tablets. Does anyone here chew or crush their Levothyroxine?

Any further advice or reading suggestions very welcome. Fortunately I have hardly any symptoms (anxiety/cold sensitivity), just unfortunate blood test results!

Thanks everyone. :)

There isn't a particular make in the UK that people prefer over others that I'm aware of.

It is quite common for people not to get on with Teva Levothyroxine. But having said that there are some people who get on extremely well with it and prefer it to any other.

Does anyone here chew or crush their Levothyroxine?

The only problem with chewing Levo (or any other prescribed drug or hormone) is that bits might get stuck between the teeth then get spat out when cleaning the teeth so you lose bits of the dose. But I'm not aware that just chewing your Levo will be a problem.

If you crush Levo, would you plan to put it in water or swallow it as a powder? If you put it in water I'd expect a similar problem with that as with chewing it - bits might get left behind and then lost.

Hi Humanbean,

Thank you for your reply and insights. I guess I will have to trial and error a brand and see how it goes. I read a forum about side effects and it was just tons and tons of people complaining! Kind of made me wonder if certain brands are notorious.

I would probably crush and then just eat off a spoon or add to honey and then take a drink to make sure there is no missed residue.

Not being able to swallow tablets is such a pain!

Once you find the make of Levo that suits you best you can ask your doctor to name the brand on your prescription. (I'm assuming you live in the UK.)

I think there might be a specific form of wording that will force the pharmacy dispensing your prescription to give you the make you want. But I'm on shaky ground in saying that. And whether or not electronic prescribing changes that in any way, I really don't know.

helvella will probably know.

I don't know! But I think I have picked up that it must be on the first line.

The USA has a way of saying "no substitutions".

Thank you. Yes, I have seen that we can ask for specific brands. Hopefully I'll pick a good one that suits me first time. :)

I looked at the British National Formulary but it doesn't appear helpful in this matter:

bnf.nice.org.uk/guidance/pr...

Whereas this Greater Manchester document is fairly full but not sure if it is sufficient.

I found it very difficult to swallow any tablets for decades ... until I improved my thyroid levels.

That's interesting. Can you explain a bit more? I have anxiety about it. Did you chew/crush your tablets?

Hi I take Levothyroxine oral solution at night via a syringe. Best brand is Mercurypharma as other brands have too many additives.

helvellaAdministratorThyroid UK in reply to Alimax

I don't understand what you mean by "too many additives"?

In additon to the levothyroxine Active Pharaceutical; Ingredient, the UK makes have the following numbers of exciepeints (other ingredients):

Actavis - 5

Advanz - 5

Aristo - 6

Teva - 6

Wockhardt - 4

That is, Aristo and Teva have one more ingredient. Wockhardt has fewer.

I have tried other solutions but sugars and E217 are not suitable for me + other brands are difficult to get consistently.

It is very much trial and error I’m afraid. The problem is often the fillers we react to, not the Levo itself so as someone has already said, once you know what your body reacts to don’t order that brand in future. May be start off trying the more popular brands your pharmacy can order or already order so a chat with the pharmacy could help. I asked when I started out when asked what brand I wanted and was told back then Mercury Pharma was easy to obtain so got that and I was successful first time. If you pick one a helpful person on here recommends then make sure your pharmacy doesn’t have issues getting it with the risk they may let you down.

What are your most recent thyroid results?

Anxiety is common hypothyroid symptom

SKalila profile image
SKalila in reply to SlowDragon

Hi, thanks for asking.

TSH: 9.95 (0.270-4.2)

Thyroglobulin Antibodies: 381.6 (0-115)

Thyroid Peroxidase Antibodies: 321.2 (0-34)

I tested positive for antibodies in 2016 and have been tested yearly for TSH with my GP. The results vary each time, this is highest my TSH has ever been, usually it swings between 4.something and 6.something.

Had anxiety my whole adult life, wondering if the whole time it was my thyroid, hypo runs in my family.

SlowDragonAdministrator in reply to SKalila

So if you had high antibodies, symptoms and TSH over 4.2 GP could/should have started levothyroxine then

See flow chart on top of page 2

gp-update.co.uk/Latest-Upda...

As you have high antibodies this is Hashimoto's, (also known by medics here in UK more commonly as autoimmune thyroid disease).

Hashimoto's frequently affects the gut and leads to low stomach acid and then low vitamin levels

Low vitamin levels affect Thyroid hormone working

Hence so important to regularly retest vitamin D, folate, ferritin and B12

Poor gut function can lead leaky gut (literally holes in gut wall) this can cause food intolerances. Most common by far is gluten. Dairy is second most common.

According to Izabella Wentz the Thyroid Pharmacist approx 5% with Hashimoto's are coeliac, but over 80% find gluten free diet helps, sometimes significantly. Either due to direct gluten intolerance (no test available) or due to leaky gut and gluten causing molecular mimicry (see Amy Myers link)

Changing to a strictly gluten free diet may help reduce symptoms, help gut heal and slowly lower TPO antibodies

While still eating high gluten diet ask GP for coeliac blood test first or buy test online for under £20, just to rule it out first

healthcheckshop.co.uk/store...?

Assuming test is negative you can immediately go on strictly gluten free diet

(If test is positive you will need to remain on high gluten diet until endoscopy, maximum 6 weeks wait officially)

Trying gluten free diet for 3-6 months. If no noticeable improvement then reintroduce gluten and see if symptoms get worse

Non Coeliac Gluten sensitivity (NCGS) and autoimmune disease

ncbi.nlm.nih.gov/pubmed/296...

The predominance of Hashimoto thyroiditis represents an interesting finding, since it has been indirectly confirmed by an Italian study, showing that autoimmune thyroid disease is a risk factor for the evolution towards NCGS in a group of patients with minimal duodenal inflammation. On these bases, an autoimmune stigma in NCGS is strongly supported

ncbi.nlm.nih.gov/pubmed/300...

The obtained results suggest that the gluten-free diet may bring clinical benefits to women with autoimmune thyroid disease

nuclmed.gr/wp/wp-content/up...

In summary, whereas it is not yet clear whether a gluten free diet can prevent autoimmune diseases, it is worth mentioning that HT patients with or without CD benefit from a diet low in gluten as far as the progression and the potential disease complications are concerned

restartmed.com/hashimotos-g...

Despite the fact that 5-10% of patients have Celiac disease, in my experience and in the experience of many other physicians, at least 80% + of patients with Hashimoto's who go gluten-free notice a reduction in their symptoms almost immediately.

Why gluten intolerance can upset cortisol levels

kalishinstitute.com/blog/gl...

Astonishingly cutting out gluten can help reduce anxiety for some Hashimoto’s patients. I personally found this was the case too

Wow, thank you so much for all that info. I have been working with a functional medicine doctor and have been gluten free now for almost 3 months. So far I have noticed a big difference in PMT symptoms. I also have lichen sclerosus, which I understand is connected with thyroid issues.

My FM GP is helping me with my supplements (I am v low on B12 and Vit D) and I'm currently trying to find someone to give me B12 injections (proving more difficult to find someone than I first anticipated!).

I will check out those links, thanks again! :)

Glad to hear strictly gluten free diet is helping

How low was vitamin D?

GP will often only prescribe to bring levels to 50nmol.

Some areas will prescribe to bring levels to 75nmol

leedsformulary.nhs.uk/docs/...

GP should advise on self supplementing if over 50nmol, but under 75nmol (but they rarely do)

mm.wirral.nhs.uk/document_u...

NHS Guidelines on dose vitamin D required

ouh.nhs.uk/osteoporosis/use...

But with Hashimoto’s, improving to around 80nmol or 100nmol by self supplementing may be better

ncbi.nlm.nih.gov/pubmed/218...

vitamindsociety.org/pdf/Vit...

Once you Improve level, very likely you will need on going maintenance dose to keep it there.

Test twice yearly via vitamindtest.org.uk

Vitamin D mouth spray by Better You is very effective as it avoids poor gut function. There’s a version made that also contains vitamin K2 Mk7

It’s trial and error what dose we need, with hashimoto’s we frequently need higher dose than average

Calculator for working out dose you may need to bring level to 40ng/ml = 100nmol

grassrootshealth.net/projec...

Government recommends everyone supplement October to April

gov.uk/government/news/phe-...

With your Vit D, are you also taking it's important cofactors - magnesium and Vit K2-MK7?

Magnesium best taken in the afternoon or evening, but must be four hours away from levothyroxine

How low was B12

Have you had test for Pernicious Anaemia?

pernicious-anaemia-society....

If you have B12 injections Or taking B12 supplements it’s recommended on here to also to supplement a good quality daily vitamin B complex, one with folate in (not folic acid) may be beneficial.

This can help keep all B vitamins in balance and will help improve B12 levels too

Difference between folate and folic acid

chriskresser.com/folate-vs-...

Many Hashimoto’s patients have MTHFR gene variation and can have trouble processing folic acid.

thyroidpharmacist.com/artic...

B vitamins best taken after breakfast

Igennus Super B is good quality and cheap vitamin B complex. Contains folate. Full dose is two tablets per day. Many/most people may only need one tablet per day. Certainly only start on one per day (or even half tablet per day for first couple of weeks)

Or Thorne Basic B or jarrow B-right are other options that contain folate, but both are large capsules

If you are taking vitamin B complex, or any supplements containing biotin, remember to stop these 7 days before any blood tests, as biotin can falsely affect test results

endo.confex.com/endo/2016en...

endocrinenews.endocrine.org...

Low B12 symptoms

b12deficiency.info/signs-an...

If Serum B12 result is under 500, then taking a B12 supplement and a B Complex (to balance all the B vitamins) initially for first 2-4 months, then once your serum B12 is over 500 (or Active B12 level has reached 70), stop the B12 and just carry on with the B Complex.

Yes lichen planus and lichen sclerosis both frequently respond well to strictly gluten free diet
