Advice on splitting a Levo dose to achieve optimal levels

Hi all

I’m in a place where 75 Levo is too little (bottom range T3 and 4 and TSH nearing 5)

We’re going through IVF and my dose was increased (at my request) to 100. Which felt great for 6 weeks or so. 24th October blood test showed 0.4 TSH and T3 and 4 reaching top quartile.

Yesterday we found out the embryo transfer hadn’t been success (started to implant but stopped) and I can’t helping noticing that I’m feeling slightly over medicated (hot, thyroid “thumping” type sensations that I’ve had before. And I wonder whether this had anything to do with the loss

But I know going back to Levo 75 will be too low - I think I need a split between 100 and 75 to sit where I feel good, which is at the reading levels on 24/10 (any lower TSH wise doesn’t feel right)

do you split the pills?

Jessica so sorry for your troubles.Some folks take 100mcg one day and 75mcg the next day. This is fine to do if that suits you.

My body didn't like different amounts different days so I ended up splitting tablets with a basic pill cutter.

You could also try splitting your dose so take a 50mcg tablet in the morning and the rest of your daily dose at night. This can help as it is gentler on the body and there is not such a high spike when the peak of the dose enters the system.

thanks so much for your reply - splitting it and taking half in the morning and half at night is something I might try, thanks for that 🤩

Which brand of levothyroxine are you taking for 75mcg and which brand is 100mcg tablets

Many people find different brands are not interchangeable

Was new test done 6-8 weeks after dose increase to 100mcg

Always test thyroid levels early morning, around 9am latest and last dose levothyroxine 24 hours before test

ESSENTIAL to test vitamin D, folate, ferritin and B12

Have you had these tested

What vitamin supplements are you currently taking

Have you had thyroid antibodies tested for autoimmune thyroid disease

You could reduce dose a little if you feel over medicated …eg 100mcg 4 days a week and 75mcg 3 days week

But ideally get full thyroid and vitamin testing done first before changing dose

Only do private testing early Monday or Tuesday morning.

thanks so much for your reply

I’m not sure on the brand of levothyroxine, but they’re both the same, I’ve put a picture of the box below

I’ve also had a full thyroid check up (see results below)

Thanks Slow Dragon, here’s the reattached results

Is there a difference between the two antibodies as only one of them is out of range, peroxidase is fine and always has been

So Almus is Accord brand, boxed by Boots as Almus

Accord also boxed as Northstar via Lloyds pharmacy

Accord don’t make 25mcg tablets

So how are you getting 75mcg per day ?

Cutting a 50mcg tablet in half to get 25mcg?

Jessica1987 in reply to SlowDragon

I’ve dug out a 75microgram pack and they must be different brands then (let me know if the photo doesn’t come through. I’ve been taking 100 on alternative days just because it felt a bit hyper but the latest blood tests don’t show it quite out of range yet. This happened when I moved from 50 to 75, at first I went from high TSH to low (and high T3 and T4 but then it settled down again and within a year, 75 was getting to be too low a dose and that’s where the 100mcg came in. I feel like it only needs a teeny tiny adjustment, as if I went back to 75 it would be too low

75 vs 100

Suspected as much

Teva is the only brand that makes 75mcg tablets

Many people find Levothyroxine brands are not interchangeable.

 Many patients do NOT get on well with Teva brand of Levothyroxine.

Teva contains mannitol as a filler, which seems to be possible cause of problems. 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.

Most easily available (and often most easily tolerated) are Mercury Pharma or Accord

Mercury Pharma make 25mcg, 50mcg and 100mcg tablets 

Accord only make 50mcg and 100mcg tablets 

Accord is also boxed as Almus via Boots, and Northstar 50mcg and 100mcg via Lloyds ....but Accord  doesn’t make 25mcg tablets

beware 25mcg Northstar is Teva

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).

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...

markvanderpump.co.uk/blog/p...

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

Similarly if normally splitting your levothyroxine, take whole daily dose 24 hours before test 

Increasing number of members find it smoother/more tolerable to split levothyroxine as two smaller doses, half dose waking, half dose at bedtime.

vitamin levels are good

B12 might be a little high as is over 150

High TG antibodies

Currently NHS doesn’t readily diagnose autoimmune thyroid disease if ONLY Thyroglobulin antibodies are high 🤷‍♀️

Jessica1987 in reply to SlowDragon

yes, my b12 has always been quite high but it seems to have fallen slightly. I take well woman max as a supplement and there always seems to be such a high RDA of B12. Does having high b12 affect thyroid? Or is there no link.

Yes, strange as all the attention always seems to be peroxidase and thyroglobulin just gets ignored 😂

Recent research suggests Both folate and B12 might be Goldilocks vitamins for pregnancy

most autoimmune thyroid patients have high TPO or high TPO and high TG antibodies

But significant minority, like you only have high TG antibodies
