Levothyroxine Side Effects (Page 19)
(Newest replies 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 am 31 years old and diagnosed with underactive thyroid recently and i am taking SYNTHROID. I don't know what the difference with that and LEVOTHYROXINE. I am taking 50 mcg and I don't feel weird at all, I actually feel better and more energy for me.

Weight gain, speech slurred. Say the same sentence more than once. Can hurt your total ability to think and concentrate, (don't drive.) Over all total health can be extremely dangerous. Can become diabetic, manic depressed, and maybe even with suicidal thoughts. I stay on my meds regardless of what the out come. That little butterfly known as the thyrid gland controlls your body. When removed the body can't function without it, for your safety take the meds. Never increase the dose on your own, can cause damage to the heart muscle. Even death can occur.

synthroid 225 mcg, weird more like, on meds for over 27 yrs. today i noticed that one of my living room chairs was moved. (2/20/2011) my husband said he moved it three days ago.
Be strong, don't under estimate yourself. Think of what you have accomplished in your life. Then ask again, are you crazy ? (probably not) This might sound stupid but crazy is not us user with meds. Blame America for not letting us use bet superior quality medication, Forsay like in Japan, Canada, France, Mexico and other countrys who have cures and we are a large government with uncaring congres. Who let the pharmacutical company control are well being. When you are down, think good deeds and thoughts.

Marie, I don't even have a lot of anxiety generally and on this medication, I was in complete panic (first, I didn't suspect the meds, since the doctors told me that they don't have any side effects). I saw my endocrinologist and told him how I had horrible palpitations and woke up breathless in the middle of the night (this was SCARY!), that an EKG was done, etc. He was looking at me suspiciously and asked whether I felt anxiety about taking the medication so that THAT caused my heart to pound like a drum section. I politely asked if it is so impossible to have these side effects from the drug. Well, he said, in his 30-year career he saw maybe two people who reacted to the medication, so it is extremely rare. After prescribing 75 mg, then 25 mg, then 12.5 mg (told me to break it), now it's 12.5 mg every other day... I don't want to do this. I felt better while on nothing, honestly. They explained to me how underactive thyroid is very bad for me. Well, waking up breathless in the middle of the night, BAD palpitations, insomnia and panic felt even worse.

I have been taking 50mcg of this medicine for just over a week. I also suffer from a debilitating andiety disorder called agoraphobia and these last 3 days my anxiety has been heightened and I wonder if anyone else has felt this.

I was diagnosed with an underactive thyroid and PCOS in september, doc has finally arranged treatment of thyroxine and metformin for me. Started the thyroxine on wed this week, havent noticed any changes yet, probably too early. But i have been getting odd stomach pains constantly, and a lot of wind! Is this normal? I did have the flu at the beginning of week, but the stomach pain started when i started the medication.

Exactly!! That is why they are called Practioners...they are practicing medicine on all of us. I wish Doctors would listen to their patients instead of having the "I know more than you and you don't know what you are talking about" attitude.

Ok, There is nothing else from the nhs so try this. My Gp suggested taking it with food to offset the stomach problems and it helped but I also needed stomach meds for a month (ppis) to settle it down. Then I needed to give myself days off to keep from being bloated again. It was then I found out about starting low and increasing the dose really slowly so I take it alternate days at a low dose and will slowly increase it maybe even 6 monthly until I get to where the Gp wants and I want without heart futter, bloating, indigestion and a mussy head. I also may lose my temper the next time some well meaning twit of a doctor tells me there are no adverse side effects!

It seems like the medicine they give us does more harm than good. My heart actually beat off kilter. I don't know how to describe it but it was like it was beating only on one side and I was short of breath. Isn't there anything else they can precribe besides levothyroxine? I would rather not take anything. Ever since being on this drug I react to all medicines. Even allergy pills mess with my heart now.

Sharon - your symptoms are the same as mine. I have been taking levothyroxine for about a week and I feel bloated, it feels like a rock is in my stomach and I'm a little down.

I just started on the medicine last week and feel very bloated. My question to you is, have you gained the weight since you started taking the medicine? I'm feeling weird but it's more like I'm on edge and get snappy quicker than usual.

Hi Laura, I too got a funny heart beat (atrial fibrillation) that was put down as coincidence after starting thyroxine. I got all sorts of other problems too and ended up being offered more and more different pills to sort out the problems it caused so I stopped the thyroxine went back to being sleepy and got rid of all the other problems. I then explored more because I knew that I needed the thyroxine. If your thyroxine has been low for a long time it is vital to start on a low dose and work your way up very, very slowly. If you go too fast you'll get symptoms of 'overdose' which include palpitations etc etc.... so yes 25mcg for as long as it takes then 50 then 75 or whatever but do it slowly and hopefully you too will feel better. It's just a shame that Gps just ignore us! Good luck

Im 16 years old and female and i was diagnosed with an underactive thyroid around 3 months ago and was put straight away onto 50mg levothyroxine, i experienced no side affects for the first 2 months and my symptoms did seem to improve for a while but then i went downhill, i went to my gp this week who said that my blood levels will need to be checked again in 2 weeks and i will need to be on a higher dose. however, i was admitted to a&e just last night with heart palpatations and an irregular heart beat and pain when breathing. however it did feel like they were in a rush to get rid of me. i have also been getting severe headaches over the right side of my head and these affect my vision and balance, also the doctor said that i have many lymph glands up. what does this mean?!?! i just want to be normal again. anyone have any advice?

I was on Levothyroxine for several years. My heart started doing all kinds of weird things. Palpitations, skipping beats, beating irregulary. Couple of time felt like it stopped completely for a second. Very scary. At night I would wake up with racing heart. I tried to tell Dr. and she said I had premature heart beat. I quit taking the pills and my heart is almost back to normal. However, just went to Dr. and she wants me back on the Levothyroxine again only 25 mcg instead of 75. I am scared to death to start taking it again.

I'm 33, diagnosed with Hashimoto, started 25 mcg of Levo a day - after two weeks of taking it, I was constantly out of breath, felt lightheaded and panicky, woke up with rapid heat beating and out of breath. (My TSH dropped, T 3 and T 4 as well - so, clinically, it was going into the right direction). They reduced my meds to 12.5 mcg and last night (after taking the 12.5 mcg dosage for only two days!) I was woken up with no breath at all, heart pounding, I felt like I was dying. I'm incredibly scared that this whole thing messed up my heart because I've never experienced anything similar before. I'm afraid to even go to sleep. I'm seeing the doctor on Monday. Reading about your experiences helps so much!

I was prescribed levothyroxine by m Dr about 1.5 yrs ago. I swear it is making me unable to concentrate, focus my attention on anything, unable to read and absorb anything. I plan to stop taking it for a few days to see if my symptoms get better. Before I started taking this, I was sharp as a tack. Now, I feel like my brain is turning to mush.

I just happened upon this post becuz I have an appt tomorrow with the endocrinologist becuz my hair is continuing to fall out and I'm very self conscious about it.this started when I was first diagnosed with hypothyroidism and was taking Synthroid. After almost a year of hair loss I asked my doctor what could be causing out. Hair loss can be a side effect of Synthroid. She changed my medication to Armour Thyroid which is a natural, not synthetic, and my hair loss stopped PLUS the med was cheaper. Things were great until last year when the pharmacies never had enough in stock to full my prescription and after 3 or 4 months of getting partial refills and having to run around to different pharmacies just to get a months supply the pharmacy told me they can't get it any more becuz they're no longer making it. I was really upset becuz now I'm forced to take Levothyroxine, which is generic Synthroid and immediately my hair started falling out again. My MD says that I may be able to get the other type thru the endocrinologist as they can make their own formulas? Anyway, I hope so because I'm literally going bald.
