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.

I am currently taking synthroid .05 mg.  My dosage was just increased about  a week ago.  I'm not quite sure what the difference is between synthroid and armour.  I know that all Drs. don't like to use armour, though I don't know why.  My heart flutters started a few months after being on synthroid.  My dosage was decreased and finally the flutters went away...but my TSH rose to 35!  Needless to say they slowly increased my dose again to what it is now.  The only difference now is that I am on name brand synthroid instead of generic.  This does seem to make some difference.  Anyhow, I've been to a cardiologist and had many tests and was told that my flutters were not doing any damage.  They are still VERY scary when they occur as I'm sure you know.  Everything I've read and everyone I have asked said that being hypo doesn't cause flutters, but as you will find from this forum, there are many people here experiencing the same thing.

Are you on generic or name brand synthroid?  If it's generic, try changing to brand name.  This may help.

I have been experiencing heart palpitations and have insomnia for the past few days now.  I am on Synthroid since February and the dr. has me now at 75mcg.  I have been wondering if it's the synthroid.  I'm glad I'm not the only one who has been wondering the same thing.

I am now on 1 1/2 tablets of synthroid .025mcg.  I was switched from generic to name brand a few months ago.  My flutters did return as my dosage was increased but lately they seem to have subsided.  I don't know if the generic vs. name brand had something to do with it.  When I had originally gone on synthroid, I was told that the were no negative side effects but soon found out that was not the case. I did play around with my meds on my own and found out that my flutters decreased...I know that is not a good idea though.  It is pretty much trial and error as I am finding out.  Keep going to your Dr. and tell them what you are feeling.  I know it is frustrating.  It does help though to know that there are other people out there who are experiencing the same thing that we are.

Like the rest of you, I also get relief from the heart flutters and insomnia (also numbness and sweating) by decreasing my thyroid on my own - which makes my dr mad.  Sometimes my blood levels are high when this happens, sometimes they're low, so I can't figure out what's going on. Does decreasing synthroid cause my own thyroid to kick in and increase, and thereby relieve my symptoms with extra natural hormone, or does it  relieve the symptoms because I had too much thyroid in my system in the first place? All I know is that skipping days or cutting the pills in half really helps - but it takes one or two days. How does one figure all this out, and why do so many of us have these symptoms on synthroid?

Did you ever decide to increase your magnesium?  Did it help?  I feel like these palpitations are starting to control my life.
