Could Letrox and Bromergon have caused heart issues such as Afib?

Hello all

My gf was on Letrox and Bromergon for nearly a year and a half. About five months ago she started to complain of heart palpitations and tremors. Looking at the side effects of these medication we immediately suspected that these were the likely cause of such complaints. In September she went to see her endocrinologist and after taking the required blood tests was told that they were within the range and was told to stop taking Letrox and Bromergon which she did. However, she still complained of rapid heart palpitations, tremors and fatigue. This month she did an ECG and the results weren't good and was immediately put on anti-arrhythmic medication by her cardiologist

Some questions. Could Letrox and Bromergon have caused such heart related issues? And could she still be suffering from an under/over active thyroid even though her recent blood tests are within the range?

Thanks and a Happy New Year

Peter

  • If she was diagnosed hypo, and prescribed levo, then yes, she is still hypo. It doesn't go away. Her bloods are only in range because she's been taking the levo. If she stops it, her TSH will rise, and her Frees will drop and she will get all her hypo symptoms back. Her endo is an idiot!

    Personally, I would think the cause of her palps was under-medication. Most hypos are under-medicated, because doctors - even (or especially?) endos - have no idea how to treat them. One of the causes of palps is low thyroid. I don't suppose she has any copies of her blood test results, does she? If so, it would be a good idea to post them on here, with dates, ranges, and what she was taking at the time. That will give us a better idea of what's going on.

    I can't comment on the Bromergon, because I've never heard of it before. But, looking at the reasons for taking it, she probably only needed it because she was under-medicated for hypo.

  • Hello Greygoose

    Thanks for your informative reply. As soon as she is back from abroad I will take a look at her blood tests results. However, she stopped levo in September and when she had blood tests taken a few weeks ago they were within the range which led us and her endo to assume that her thyroid was okay. But then her ECG wasn't good. However, I need to really see whether she is actually suffering from an under/over active thyroid by taking her to see a better endo.

    Or you could get those results and ask us. We're more reliable than most endos.

  • Thanks :)

  • Just being 'in range' is not good enough. It's where in the range they fall that counts. If her TSH is three or over, that will be inside most ranges, but she will be hypo.

  • Thanks :)

  • My heart played up dreadfully before I was diagnosed - it took a long time as I never had a blood test taken for hypo.

    I was often in hospital getting ECGs - discharged once after an overnight stay with a diagnosis of ' probably viral with high cholesterol'. First cholesterol is a clinical symptom of hypothyroidism - pity they didn't take any for thyroid hormones as my TSH was 100 when diagnosed a week later. This had been going on for over 5 years at least.

    I hope your gf is diagnosed soon as the symptoms can be crippling. Most of the thousands on this forum have found our condition to be a DIY method to recover.

  • Untreated or under-treated hypothyroidism is often a cause of arrhythmia. Another thing to consider is that nutrient levels may be too low - and low nutrients levels is extraordinarily common in hypothyroidism. Low iron can cause tachycardia for example.

    When you look into blood test results find out whether ferritin, iron, vitamin B12, vitamin D and folate have been tested, and if they haven't ask for them to be tested. They all need to be optimal (which is not the same as just being in the reference range) in order for thyroid hormones to "work properly" in the body.

  • Interesting reply because as soon as she had stopped taking levo we thought we were going to see a gradual disappearance of the symptoms she was complaining of (palpitations, fast heart beat, tremors in the morning, fatigue). These persisted and when she visited family in Poland they persisted. She went for an ECG and the results weren't good and put on medication. As far as I know I don't think she was tested for B12, Vitamin D and folate.

  • When I was suffering from severely low iron and untreated hypothyroidism my heart rate went up to about 150 on several occasions and was well above 100 most of the time. My blood pressure was also high.

    I am no longer short of iron, and I treat myself for hypothyroidism. My heart rate and blood pressure are now normal 95% of the time, and when they do rise they are never as bad as they used to be.

  • Bromergon is Clomid, given for infertility problems (I took it back in the day). If that is the case your girlfriend is probably having problems because she is undermedicated (for her thyroid)
