Hi there
So for a little background information I had thyroid cancer when I was just 8 years old so I had it all removed. Now I do not remember what thyroid medication I was on at that age as I was very young. Anyways from what I do remember I was on liothyronine 20mg for one day then 40mg the next for a while then my Oncologist put me to 40 mg then eventually 40 mg one day then 60 mg the next as i got older. Everything was fine I do think my levels were a little high but my body was fine at the level it was at (which i dont have the numbers for but can get).
Then everything changed in the year 2015 my Dr switched my medication from t3 to t4 from what I understand but was not told was down to the price. It took a few months but my body did NOT react well to levothyroxine as my levels went sky high and I got hyperthyroidism rushed to the hospital for them to just to tell me about the bloods being high and to take less.
Anyways eventually my thyroids were switched back to just t3 only and the dose was 40mg each day. So my levels gradually fell back down I dont know the number but it did drop from what it was at with just t4s.
So this was all over 2015 and 2016 for my levels to get back to what they were before or close to it. So 2017 im still feeling some of the side effects of being hyper but not as bad. However I also take two other medications vitamin D3 and calcium supplements. In April this year my calcium tablets which I have been on since i was 8 were switched Sandocal Effervescent 500 mg (these stopped being produced now only available as 1000mg) to Calcichew 500 mg Chewable Tablets. I took these for two months but suddenly I would start to get random side effects which i thought were the cause of these new tablets.
The effects I would get was like I would just be sitting there at night and randomly i would start to get shaking rapid shaking, sweating, foggy brain and chest pounding. Like the experience I had with the the t4 medication. So this happened about 4 times like spaced out in weeks but it got so bad I went down to the hospital with it. They checked my bloods calcium etc was fine they said but my thyroid levels were high the t3 level.
So I went back to my gp and explained what was going on and he said my body is sensitive to medications changes it seems and put me back on to the Sandocal calcium 1000mg half tablets. He did mention about the thyroid levels but left it as that.
Now it has been about 2months that I have switched back to my original calcium supplement. I haven't had the extreme shakes however the sensation does sometimes come on. Other symptoms I experience are random rapid heart, sweating when I wake up at night, numbness/tingle on my temple area and top of my head, muscle soreness all over (bones), bad sleep so wake up feeling of fatigue, eyes more red than usual and like a heartburn feeling around the heart and gut area. Just general feeling horrible it is hard sometime to try and explain how you feel.
So I went back to the gp who contacted my oncologist because the gp did say my t3 was high sitting at 11.3 im sure I heard this correct I don't know all my levels currently I plan to go see them. Hyperthyroidism.
So now the t3 I take now is 20mg one day and 40mg the next to see if it brings down the t3 level suggested by my gp and confirmed by the oncologist. As they think Iam over medicated.
So medication that I take is: t3 20mg one day 40mg the next which i have been doing since tuesday (22/08/2017), Sandocal Effervescent 1000mg half tablet 500 in afternoon and one at night to space it out 4 hours from when i take my t3 and one fultium D3 800iu.
By the way I never knew about separating thyroid tablets and calcium until around 2014/15.
So this is a brief summary of what is going on with me and thyroid medications / calcium.
So I wonder did the calcium (Calcichew 500 mg Chewable Tablets) that I was switch to spark this rise in my t3 levels? or was it still high from the t4 medication and thats where it got to level wise? or was going from the dose of t4 (equivalent to 40/60mg t3) right back to 40mg t3 the issue?
Appreciate anyone who read all this and suggestions.
I understand that I’am in the minority who cannot tolerate t4 levothyroxine.
