Synthroid and heart rate

hello everyone
i am a full time college student and I believe that i have some side effects from synthroid. As i was reading everyones blog i notice that some people feel the same way that i do. At times i feel that i'm normal but if something upsetting happens i get really tired, depress, and I have a never time concentrating at school and home. My body hurts all the time. especially my joints and i feel that i don't want to do anything. I have about a year left until i graduate and its the going to be hard. I cry sometimes for no reason. help! i'm going to talk to my doctor but if any body else feels the same way please reply.

Hi i have been on synthriod for 10 years now and until 2006 i started having serious surges in my heart rate as well as my hair constantly falling out. i have been to my (endo) doctor so much about all these problems all the tsh test and blood work are fine and normal he says, but you know I really wonder had i not ever gone on this synthroid in the first place would my body be doing this. the papitations i get are so bad, and worse when i eat and settle down in the evening. nobody knows or understands me, but you all who post on this forum because you are all going threw the same thing too.

I have been on Levothyroxene for 14 months now. I have been experiencing nightmares, a "butterfly" feeling between my chest and stomach, itchy skin, dizziness, and am still fatigued. My dose is 50mcg. once a day. that was upped from 25 mcg. a day as my TSH level was not within the normal range. Sometimes I feel like I'm feeling WORSE after being put on Levothyroxene. I also am still gaining weight and am constantly bloated, having bouts of diarrhea, and my blood pressure won't stay regulated. I am currently recuperating from a bad cold and the cough is hanging on. My other meds I take are Atenolol-12.5 mg. once a day and Xanax-.25 mg. two to three times a day. Is there an interaction between all these meds(I take them at different intervals thruout the day to avoid interactions)?

I was diagnosed with a hypo thyroid and I was on 50 mcg for about 2 months now and I suffered from heart flutters that would wake me up in the night.....My doctor uped my dose for two weeks to 75 mcg and then put me on 100mcg I only took 1 pill of 100mcg and I had heart flutters and skipps, My enternal temperature went up and down, I even lost conciousness in and out, I told the doctor about it but did not go into a clinic or hospital he said take half a pill and Ill see you tomorow, so I did and felt fine for the day then on my birthday October 27 I took 75 mcg and still I was fine for the day.....But yesterday I took 75 mcg again and last night I ended up in the hospital, my girlfriend said I went from my normal coulor to yellow and my heart rate went through the roof and I felt like I was going to through up....I also felt slow. Is all of this realy necisarry....If the doctors were diagnosing us right and giving us the right pills would we not be fine.Im 22 years and have a four year old little boy to live for and my heart rate was 110 when I went in yesterday and they had to give me a pill to slow down my heart rate....I dont find that normal for a 22 year old to have to be going through. I DONT THINK SO!
Thank you all for your stories reading the side effects from all of you has helped me slightly understand this drug a little better.

PLease be careful. I have been on a suppression therapy dose of synthroid for over 8 yrs. I had thyroid cancer and my endocrinologist said I needed to keep my tsh between .3-5.6. For the last yr I have been feeling awful. My heart rate was arnd 145, I had shortness of breath, muscle aches, hair falling out, could barely eat but I gained about 30 lbs because I was swelling up from edima. I had almost every symptom of being hyperthyroid. My endo said I ran on high test!! I thought I was going crazy. I was on 2mcgs of synthroid. My tsh level became .009 and then became non-exsistent(.oooo) I now have dialated cardiomyopathy, and congestive heart failure.
So if you are not on the correct dose you can have very serious side effects. Make sure your levels are checked on a regular basis. If you are not feeling right make sure someone , like a dr listens to you and hears your symptoms. I had repeated ly told my dr how I was feeling and he said I needed to be suppressed. to prevent cancer returning, well after almost dying from heart failure how suppressed should someone be????? Now My entire live is suppressed....
