Hot flushes....too much iron ?

Hi All

I sent this huge set of results to Dr P, complaining that my (then) 75mcg of T3 seemed to be having little effect any longer - and that I had suffered from the odd pounding of my heart and felt as if the T3 wasn't getting into my cells.

He commented that my MCV and MCH show that I am short on iron and that I should increase my intake straight away and drop my T3 a little.

Well..rightly or wrongly, I dropped my T3 to 50mcg and have started taking 20ml of Floradix at night before bed (I was taking 1 sachet of Spatone). Does this sound ok ?

I ask because for a few weeks now I have been having hot flashes all day and night. They last just a few seconds and then I get really cold again. Yes, it could be the menopause of course - but I thought I was past all that. ! I wondered if it was connected to my taking too much iron ?

I'm also not sure whether to increase my T3 again. My temps are varying from 36.2-36.8 and my heart rate from 76-86 bpm.

I am seeing Dr P late July but - impatient as always - wondered if you could help !

Thanks so much..

  • Ever since getting hashimoto's 15 years ago I have been bothered with hot flashes. I realize through trial and error that it is the medication side effect for me, however it got really bad last week and a blood test showed me that normal t4 but high t3 and negligible TSH put you into the hyperthyroid state with the above stated problems. Personally I felt so bad I stopped all meds for 3 days and I am starting up again on low doses and feeling better. P.s. I also see Dr P. but as I live abroad I often have to take matters into my own hands. Here the docs are all about levothyroxine and there's nothing else. Anyway today feeling better! (But still sweating)

  • If you have pounding heart and sweats then perhaps consider overmedication of thyroid meds.

  • Thank you both for replying. I did suspect overdosing myself, but have reduced my T3 from 75mcg to 50mcg without any real difference.

    Mikiviki , interesting that you say it is a side effect of your medication. Last summer I remember experiencing a similar thing with hot flashes and I had only just started with 20mcg T3 with T4. Perhaps it is just something I will always experience with T3- or maybe I'm still overdosing on 50mcg?

  • I've been struggling in recent months to find the correct dose of T3. Two weeks ago Dr P told me I was taking too much. I had been taking around 125 and at one point had even increased it to 160. I had been changing my doses quite erratically because I really didn't have a clue what to do so I asked him exactly how I should proceed. I felt I really needed detailed guidance because I didn't trust myself at all at that point.

    He said I should reduce my current dose by 12.5 T3 then remain on that dose (even if I don't feel right) for one week; all the time taking my heart rate and temperature measurements. Then I should reduce it by the same amount again and stay on it for one week. And so on and so on until my pulse and temps were down and I felt better.

    Two weeks later I do feel quite a lot better and during the first week on the reduced dose I was quite surprised how my symptoms changed over that week. I expected to feel like I did on Days 1 and 2 for the entire week but I did gradually improve more and more. It was very reassuring knowing that I was doing what Dr P had told me to because when I felt a bit bad I wasn't tempted to alter the dose which is what I had been doing before then.

  • Mstp, thankyou. That is so helpful ! I feel like I have a plan now !

    I , too, have been altering my dose willy-nilly - without any real idea of what I should be looking for. This gives me something to work on. i'm very grateful !
