increased thyroxine dose symptoms?

Robinface profile image
32 Replies

Finally after seeing different Gp am able to increase Thyroxine from 25 to 50, now 2 weeks in- pulse is up and I feel like heart beat is in my neck- i do have horrible cold which is flu like and sinuses are worse than ever-awful! Experiencing some palpitations at random times. Bp is fine no change. Is it just my yukky cold or increase-should i do alternate days on higher dose ? Or will it settle?

Same thyroxine brand, bloods showed me in bottom of range last year, GP i saw then wouldn't increase!! Next bloods in 3 months. Thanks

Sorry you are feeling grim, a stronger heartbeat feels weird as likely you have been undermedicated for sometime but it is a good sign that your heart is getting what it needs for a change, how are you other vit/min levels as low iron and B12 can lead to palpitations.

Grab a cigar and read this link...😉 healthunlocked.com/thyroidu...

I had private tests done last year but the GP i saw then wouldnt look at them let alone act upon them! B12 was low and have addressed with diet- hoping to afford repeat tests next month. Thank you for quick response, will see how it goes- hopefully when cold thing goes i will feel some benefit of increased dose! Thanks

Likely you'd do better on a good Vit B complex.... my daughter was investigating heart palps and it turned out her B12 was within 1 of the bottom range and ferritin low too. Luckily I had primed her to question the 'normal' on her results with GP and they gave her some tablets... pretty crappy ones though so self sourcing OTC often better 🤗

Sublingual B12 works well

hi thank you which B complex does your daughter use? Struggled with a few! I am certainly warmer since increase which is good!

I used this one for the first 8 weeks as my stomach was delicate and it worked a treat, then swapped to Thorne BB

thank you much appreciated! Can i ask do you test privately? If so Who do you use? I used Medichecks last time but prices gone up!!

Medichecks often have a 20% offer each week on difference tests so keep an eye on them, if it's for TSH, T3 &4 then Monitor My Health do one for £29 but use the code to save 10% they have a new one which includes (see Below) for £65 monitormyhealth.org.uk/full...

Yep 🤗 MMH have a use by date on them that varies but discount always works on theirs so just order when needed

If you're unwell with a cold and possibly more and have been undermedicated for a while then it's understandable that you are feeling changes in your body. 50mcgs of Levo is still a very low dose and likely some of what you are experiencing are hypo symptoms. It's common to feel a bit worse on lower doses as it's not enough hormone to replace what your system was putting out. Hang in there, get bloods done in 6-8 weeks at 9am with 24hrs since last Levo dose and post the results here.

approx how old are you

Unless over 60 years old, standard starter dose levothyroxine is 50mcg

What were results BEFORE starting on levothyroxine

What were results after last blood test

Having been left grossly under medicated you likely have low vitamin levels

When were vitamin D, folate, ferritin and B12 levels last tested

Palpitations can be due to being under medicated

You could try splitting the dose…..25mcg waking and 25mcg at bedtime

vitamin results from 11 months ago here

healthunlocked.com/thyroidu...

You need to retest these

Presumably you have been working on improving low vitamin D, low folate and low B12

Are you still taking daily vitamin B complex and how much vitamin D?

Robinface in reply toSlowDragon

hi restest hopefully next month when funds allow! taking vit D spray see pic below daily but struggled with the B complex- digestive issues left me unable to tolerate so increased diet levels- not ideal but better than nothing! Thanks

Vit D spray
SlowDragon profile image
SlowDragonAdministrator in reply toRobinface

how many sprays per day are you currently taking of vitamin D?

Robinface profile image
Robinface in reply toSlowDragon

2 sprays per day i remember most days!!

SlowDragon profile image
SlowDragonAdministrator in reply toRobinface

Retest levels twice year

May not be high enough dose, especially in winter

Robinface profile image
Robinface in reply toSlowDragon

I saw on social media recently a local practitioner does B12 injections- thoughts? Is this allowed and commonplace nowadays?

SlowDragon profile image
SlowDragonAdministrator in reply toRobinface

suggest you just try B12 drops

They usually work very well and quickly

Retest in 6-8 weeks when you test full thyroid levels

SlowDragon profile image

If can’t tolerate B complex try separate B12 and separate folate

Initially only add B12

Low B12 symptoms 

b12deficiency.info/signs-an...

methyl-life.com/blogs/defic...

B12 drops work very well

healthunlocked.com/thyroidu...

or

B12 sublingual lozenges 

amazon.co.uk/Jarrow-Methylc...

cytoplan.co.uk/shop-by-prod...

B12 range in U.K. is too wide

Interesting that in this research B12 below 400 is considered inadequate 

healthunlocked.com/thyroidu...

About 2 weeks after adding B12 try adding methyl folate

Eg Jarred methyl folate 400mcg …..perhaps alternate days initially

thank you, much appreciated! Will have a look- Shall i start them then do test in a month or 2 or longer? Are they recommended to halt before blood tests? Sorry my awful headcold making me dim today!! Thank you

SlowDragon profile image
SlowDragonAdministrator in reply toRobinface

you can continue both B12 and folate up to day before blood test

Test thyroid and vitamins early morning

Last dose levothyroxine 24 hours before test

careful adding supplements, only do one new thing a fortnight or you won’t know what is causing what when something gives you a dicky tum or spinny head.

I felt weird going from 25 to 50, took it alternate days for a week and then tried again and was much better. Going to 75 was easier and better still. 125 now and I walked 2.5 miles to work and 2.5 miles back today 💪

Gotta say though on 50mcg I felt worse of all. I used the advice here to pester the gp surgery with my £29 blood test results and insisted on a raise sooner in 8 rather than 12 weeks as my symptoms were so awful. Try it.. 3 months feeling like that is just horrific. The patient leaflets in the pill boxes say 3-4 weeks but that isn’t long enough for me to settle on a dose. Wishing you a smooth titration to good health 🌱🦋🌱

I have had heart palpitations quite bad since before Christmas. Long story but I had a second blood test this week. Text received from GP tonight to say I am low in Folic Acid and a prescription is waiting for me at Pharmacist! Having read about this deficiency it does explain some of my symptoms. I am not over medicated on Levothyroxine, I am currently under medicated!!! Heart palpitations and fast heart rate is awful, hope you get sorted soon.

lots of us have the MTHFR gene mutation that affects our absorption of vitamins like folate. I was recommended to take the methylated version (L-methylfolate) (same with B12) rather that folic acid for better results. I’m waiting on a blood test myself to see if this has helped. Just thought I’d mention it, be interesting to see how the folic acid version work for you 🌱🦋🌱

Hi. I don't think I have the MTHFR gene, well not to my knowledge! I have never heard of that. Never been folic acid deficient before. I eat plenty of green vegetables, oranges, etc so not sure why this has happened. My TSH has inceased in last few months. Blood results show folic acid at 2.6 which is below ref range of min 3.90. I now have 3 months worth of Folic Acid tablets, brand Crescent 5mg once a day. Doctor never asked about my diet and hasn't suggested a blood test after taking meds. Mind you he didn't bother speaking to me just a text!!!See how it goes. Hope your blood test goes ok.
