Side effects from Thyroxine

side effects you get from L-thyroxine are fatigue, anxiety, headache,and weakness. Long term side effects involve cardiac and bone problems. The heart may pump more than usual due to the increase in energy and it may lead to cardiac overload. Also, bone mineral density decreases resulting to osteoporosis when used for quite a long time because it disrupts the work of calcitonin, a parathyroid hormone for

bone mineralization.

The three most common side effects of L-thyroxine are changes in appetite,increase in sweating, and noticeable hyperactivity. Due to the increase in energy, your appetite will surely increase because the stomach gets emptied faster due to quicker metabolism. By that, you get hungry and tend to consume more than your usual consumption. The increase in sweating is also linked to the idea of more energy. One way in metabolizing waste is through sweating and because of L-Thyroxine, the energy is increased, leading to a hastened metabolism leaving the person sweaty.

Hi everyone, I know this conversation happened a few years ago but I have to admit that some useful infirmation were shared here. I have been diagnostic of hyper active thyroid 1 year and half and went for surgery to remove my thyroid and i have been under thyroxin tablets ever since. I'm moved from 100/day to 125/day now but can't stop feeling exhausted, any stress situation will have impact on my body (shaking, accelerated heart beat)! I'm really concerned as I'm 32 and have no children. I had a blood test done by specialist which results came back being normal... So I don't know what to do anymore!!! I also feel emotionally drained and have no energy which my friends see as a depression so I decided to consult someone about it. It's yoga therapy treatment I started only couple of weeks ago. Quite expensive but I'm willing to do anything to finally get back to normal which I have to admit not being sure anymore what normal is for me... Any tips would be appreciated. Thanks in advance

Hi there. My mother in law really didn't get on with the thyroxine prescribed by the doctor and her blood levels were all over the place. However she now uses animal thyroxine she buys off the internet, much to the doctor's horror.

I hope you manage to find a way to alleviate your symptoms really soon, it sounds awful xx

My feelings are still the same as before - I think it is very risky messing around with thyroxine without your doctor and I would never buy any over the internet.

Hi everyone, I was diagnosed about 7 years ago and I'm just beginning to realise that this condition has triggered lots of other medical concerns since. Always wondered if it was linked but now I am convinced. First I had vertigo which was horrible, very disorientating when driving with 4 kids in the car, always feel like my brain is fuzzy, hazy (if that makes sense). Had one or two anxiety attacks over the years which I think was linked to the vertigo. Then this summer we went on holiday and I had full on anxiety attacks throughout the whole holiday, it was horrible. Convinced myself I am maybe going mad. At one point I ended up getting an ambulance as I thought I was having a heart attack, did I mention the palpitations!!! They are scary. All the above has finally led to depression, which I think I have been battling with for months but have struggled through. Yes I know I sound like a hypochondriac, I used to be a confident happy (most of the time) person who liked a night out. I never drink now as I feel the alcohol magnifies all the above symptoms. Sorry for the long rant.

I take 112.5mcg per day and want to reduce to about 50. I know this sounds un-do able but don't want to rely on medication. Read that your body gets used to the synthetic stuff and therefore you are unable to produce the correct level on your own anymore. Going to ask doc if we can do a trial for a month and get the nurse to check my levels every week, will try to change my diet also, as I eat a lot of carbs. The palpitations bring on an anxiety attack which I am learning to control with relaxation techniques. Any feedback would be great. Does anyone else get the same symptoms?

I have read a lot of your info. I was diagnosed with an underactive thyroid when I was in my mid 30's I am now 62. When first diagnosed I was given a bottle of oroxine tablets. When the bottle was finished I never took again for some years. I was never told that I would have to take for the rest of my life. I suffer a lot from being tired, sometimes I feel like my knees are going to collapse under me. I keep getting told that it is my thyroid. But all my tests come back in the "range". When I asked why I am so tired the Dr just shrugged their shoulders.

I finally went to a Naturopath and she doesn't subscribe to cancelling medical advice. She didn't tell me to stop taking my medeication. She did give me a list of blood tests to get my new Dr to do and everything she had tested there was something wrong with so it does pay to change Drs and get 2nd opinions from other sources. I went to a so called "Specialist" on thryoids, he said my weight gain had nothing to do with my thryroid??

I am on 1oomg every day and 50 every 2nd day and am also on reverse T3 which a lot of GP will not test you for. I am lucky that my GP is also a Naturopath (not the one I am seeing) so she understands both sides of the specftrum.

Hi there, I'm 19 and was told that i have an under active thyroid about 2 months ago now i have been taking 75mg of Thyroxine everyday. Within 3 days of taking these tablets i started being sick around an hour or 2 after taking them and have had a constant headache for the last 2 and a half weeks as well as being tired all the time but when i try to sleep i find that i get restless. is this normal? and how long will it be before i feel normal again? xx

Let me add my 2 cents now. I have been taking thyroid medication for ten years+ for hypothyroidism. At the beginning of the treatment i felt great, i started to lose the extra pounds, my hair looked great, everything was great.....now almost 8 years later, my doctors have somehow sent me into hyperthyroidism. I have no clue as to how this could happen, i go get my blood taken, i read all the symptoms, i understand my body.....when i don't feel well, i go to the doctor. All this time i have been told that my blood work was fine and i would need to deal with my symptoms. Now, they don't want me taking any medication, in fact they said stop taking this medication for 8 weeks! So tell me now, what am i supposed to do? At first, i thought, these people are crazy...ill find another doctor. Then, i called around and the waiting list are outrageous plus they want your medical records. I am still waiting to be seen and yes i have been taking my medication against the doctors wishes. I am however, beginning to slowly ween myself off. What other choice do i have? So i start my journey with no medication and ill let you know what happens, if i don't die first!

BTW: i found that the more expensive synthroid was a lot better than the levothyroxin; yes they are essentially the same medication but they do have some different chemical makeup. They release the medication into your body at different amounts. It may sound like nonsense, but it made a difference for me.

I also would like to add that just because your number are "normal" doesn't mean they are correct. Maybe you can talk your doctor into a smaller or higher dose, depending on the range. Sometime this makes the medication start to work again; i have found that to little or to much produce the same side effects. I also take medications now for anxiety....one diagnosis usually leads to another. Good luck to you all and i hope when i go in to see the endo, they can actually DO something to help me!

I had no idea that thyroxine has such an effect. I just thought it was normal to feel anxious. My doctor doesn't do regular tests unless I ask him um I had thyroid cancer.
