Synthroid and frequent heart flutters

[Tinsk]

I was diagnosed with hashimotos disease about 6 months ago and put on .025mg of synthroid.  After a few months, I started to notice my heart flutter.  It eventually turned into a feeling that I experienced everyday...several times a day.  I had all the work up done by a cardiologist and nothing showed up.  My GP finally reduced my synthroid to half a pill.  When my numbers were checked a month later my TSH went up to 35!!!  But, my flutters went away.  My synthroid was increased again to .025mg and guess what is comming back...MY FLUTTERS!!  I want to know if there is anyone out there who is having or has had the same expierience.  I feel like no one that I know can relate and it scares me.

Hi everyone!

I was diagnosed about two years ago as having an underactive thyroid. Last year, after losing a considerable amount of weight (which I liked), and high blood pressure (which I don't like), and a racing heart beat, the doctor then tells me after my general concern, that I have an overactive thyroid. I was put on PTU, and had been on it for some months, no change. I changed doctors, and my new doctor re-evaluated me and noticed that my numbers were now low, so I am back to an underactive thryoid. I now take Synthroid, because I have a gotier, and I imagine this is going to make it shrink, or atleast get my numbers to where they need to be. My hair has fallen out, and I have gained some of the weight back that I lost, but my main concern is this funy feeling that I get in my chest. I don't have it all the time, like most of you do. I sing alot, and have noticed that when I sing I get this feeling.I have had an EKG, EEG, and anything else that monitors your heart. Maybe someone can please tell me what this is, because it is very scary.

Thanks for responding...How did you deal with the insomnia?
Did your doc put you on sleeping pills etc? This whole thing is the absolute worst.

Hi, been there, Have Hashimoto's, also was started on 50mcg when first diagnosed a year ago, and went up in dose real fast.  Now that you have started treatment, really keep a log of symptoms.  When I was diagnosed, I had everything wrong with me that I could have wrong with me, and each time they raised my dose I felt better.  Your level is pretty high right now, I'm thinking you will notice more of an improvement as they mess with your dose alittle more.  Sometimes this whole thing takes awhile, but you will find your dose.  Good luck

I feel I'm losing my mind!  Over the last two months or so I haven't been well.  Finally my labs were done and they showed a TSH of 10.71 and antibodies of 2800. An ultrasound of my thyroid was normal along with my free T4 and T3.  My endocrinologist diagnosed me with either subacute lymphocytic thyroiditis or either the beginnings of Hashimoto's and put my on 50mcg of synthroid of which I've been on for 2 weeks now.  The first week, no effect.  The second week was hell. I had problems, awfull problems, falling asleep, felt like my mind was racing.  If I was able to fall asleep I would wake up automatically after 4 hours or so and couldn't get back to sleep.  Of course, my doc gave me sedatives and sleeping pills etc which in themselves really don't give me a sound sleep either in addition to ruining my day by being so groggy and hung over. My doc said I must take this med and this dose, that it's a very low dose and my body should tolerate it.  This is caused me so much anxiety thinking my body won't get adjusted to this and that I will need it to live.  Please help.  Is 2 weeks too early to tell?  Will my body get used to this?  I would appreciate hearing from anyone that has been there and that can help me.

I started having heart flutters 2 days ago & today it was worse, along with low blood pressure.  I'm not on any medication & haven't had my thyroid checked lately.  I've had problems with borderline high TSH in the past but it always goes back to normal on its own so they've never put me on meds.  The heart tests always come back normal.  I have mitral valve prolapse so my heart flutters might be from that, but I feel like it's my thyroid.  My mother has history of thyroid problems & had to have hers removed.  Is there anything I can take when I get these flutters & low pressure back to normal?

I found all the comments so comforting. The heart flutters are the most frighting thing I have ever experienced. I went to see a doctor, had EKG's and even went to the ER one night because I thought I was having a heart attack. Guess what they all said anxiety even gave me another Rx.  It took me a while to figure it out on my own. What did I do differently that brought on the flutters? It came to me that Synthroid must be taken first thing in the morning and on an empty stomach. I had started to take it after breakfast on a full stomach, or sometimes late in the day.  Well, guess what, no more flutters. I am following the instructions and I feel great !
