Levothyroxine Side Effects (Page 14) (Top voted first)

I was recently diagnosed with an underactive thyroid. I have been taking levothyroxine for almost two weeks. For the last four or five days I have had a weird feeling. It is hard to explain. I don't really feel dizzy but I get a strange feeling in my head. I guess you would describe it as a head rush. Has anyone else had this feeling and will it go away as my body adjusts to the levothyroxine?

I have only been taking levo for about one week but I have experienced anger and depression and want to eat all the time, I wanted to lose weight not put it on so I am going to really try not to over eat, but if this keeps up I am going to go back to the doctors and ask him to change the dosage.

Absolutely ask your doctor. I finally cornered mine and asked just how low my thyroid was and do I really need to be on any medication...Well guess what... I dont' need to be on the medication. Years on levo and all the problems it caused and my thyroid was not that low that I really needed to be on any medication. So my heart got messed up for nothing. Hopefully after being off for a few years things will get back to normal. Good luck everyone.

Yes it causes heart palpitations, skipped beats, irratic beating. Also causes painful joints on some people, I was one. My doctor finally took me off meds. Said my thyroid was not that low and we would keep checking it periodically. Thank God is all I can say!

yes, i've had the same problems. the foggy head, dizzy, buzzing or zapping feelings. that is my indication that my dosage needs to be upped. also, tired and moody. my dr. told me for 2 yrs my levels were fine, i changed drs and they said i was low. so, i dont know how a dr could mess that up but they do. i had another dr (just after childbirth) tell me my levels needed to be lower, i disagreed with him and he insisted. 2 months later, many pounds later and feeling awful, i insisted they retake the test and have someone else read the results, sure enough, i needed the dosage tripled!!! trust you gut feeling,

I have been taking Levothyroxine for six months and have had chronic stiff neck and shoulder pain. I weened myself off and was taking iodine plus 2 which helped me significantly however I am now getting the symptoms back of low enery, loss of hair, etc. It is time to seek the doctor for another medication. I know the medication is causing stiffness and neck pain, hair loss.

Do not know how to describe how I feel on Levo. I just feel like I am going to die. It is an awful feeling. I take it as soon as I wake up, go to restroom, feed some cats, make coffee and drink two cups with diet sugar and powdered cream. In the morning, I am not going to drink coffee to see how that makes me feel. Also my legs ache all the time. Do not know if it is the thyroid meds or not.

Yes it has been known to cause muscle aches and pains, stiff joints, etc. It also can cause heart problems. I had all the above. Finally asked my doctor just how low my thyroid was and she said only a little low. I am off all meds now. What a relief. My heart is getting stronger again and my ankles and knees don't ache anymore. I would recommend asking your doctor for a natural replacement. Something like Armour Thyroid which doctors has prescribed for more than 50 years before the synthetic levothyroxine came on board. Good luck and I hope you feel better soon.

I had the same feeling when I was on too high of a dosage. Check with your doctor to see if your's may be a little too much.

Have been taking this medication since Sunday July 17 and I was feeling a bit dizzy but today I got a real buzz I had to stand totally still, hold on to a gate and the world was spinning. Didn't like the feeling at all. Does this go away? Also have been feeling as if it's a little hard to swallow at times. Is this part of the side effects too?

I was having hair loss and having mood swings. The doc changed my dosage and I began taking biotin supplements and hair loss has almost stopped!

It's 12 months since I started taking this and whilst I can't say I've totally mastered it things are getting better. No, I still haven't reached the heady heights of at least 100mcg a day which my dr says I need according to blood tests but I do take 75mcgs most days with no side effects. I've even got as far as taking 100mcgs twice a week most weeks. How...Start low and take it slow.. much slower than most drs think. I started taking 25mcgs alternate days and bult up adding one day at a time every 4 to 6 weeks. If I got side effects I just went back a step or/and stopped it for a day or two. It is only now that my energy levels and hair are improving. Yes, we need to take the damned stuff but any is better than none so my doctor concedes he'd rather I did it my way than tip up at his surgery each week with palpitations, abdo pain, nausea, dizzyness and the rest. Hope this helpsG

Thank God I found this site! Iwas beginning to think I was losing my mindJuly. Taking 125 mcg daily as of July 1. Awful anxiety & just "weird" feelings that are so hard to explain. Have a doctor visit on Aug 29 & will surely discuss this. Its becoming unbearable. Thanks to everyone for all your posts & feel better fast!

I was diagnosed back in 2001 with hypothyroidism. I have been on several different kinds of medications. I took myself off completely for a couple of months within the first year of taking meds. I had originally gone to a general practioner and I was concerned that I was perhaps not getting the correct strength. I ended up going to an endocrinologist and got put on whatever strength he thought was best. I can honestly say that I didn't feel any different being on or off of the meds. Now that it has been 10 years, I can describe how I feel as this, I do get that weird feeling in my head sometimes, I am spacey, I can't think of what I want to say a lot of times, I loose quite a bit of hair whenever I shower, and I am always cold. I LOVED it this summer when it was 90' and I could sit outside and be hot. It was so nice. My dosage now is 112 MCG. The last time that it was raised was a year ago from an 88MCG. I think when I first started out, it was a dose of 50MCG. I took a generic form of Synthroid at the beginning, but don't know which one that was. I then moved to actual Synthroid for a couple of years, but insurance was no help and Synthroid is quite pricey. I have been taking Levothyroxin for approximately 3 years now. I feel like I am between a rock and a hard place. I have to take something for underactive thyroid. But it seems that anything out there has some kinds of effects that are unappealing. I would love to find a natural alternative, but am ignorant as to what is out there and what are the positives and negatives of those. My mom has been taking thyroid supplements since she was 25. She is now 68. She has been through a lot. She is currently taking Armor Thyroid. She said for the longest time that she was happy on that. But now, she said that she is experiencing weakness in her arms and some brainfog. Well, this has been my experience. I hope that it can be of some help to someone.

BIG thing that my doc says many docs don't mention is sticking with the same manufacturer if your meds work for you...if not check out a different one. I have seen such a difference since I have done this. Also, she said buying a 3 month script at a time to ensure more consistency with how the meds are made...No matter how much of a perfected science pharmacists/or makers can still commit small errors...at least the doses are more consistant this way...Also, realize that there is an adjustment period and the chemical imbalance that was there before you started the meds!
