Levothyroxine And Fainting (Page 2)

I was a perfectly healthy 14 year old until I grew very tired and went to see a doctor. We got blood work done & my tsh level was 150 (very bad) so my endocrine put me on 88mcg of levo. Im a little over a month into taking it and I've become very short of breath, having trouble excersising and today I fainted. I felt really nauseous and within 1 minute I passed out. Has anyone else experienced this?? I don't think it's normal but I'm curious if or how they fixed it. thanks

Please go and see a good endocrinologist or someone who know the TSH etc some surgeons do know well the functions of thyroid everyone is different no one person is same I suggest found one good doctor who you can trust and tell him and do some tests and avoid those up and down I use 150 thyroxine daily plus 200 on weekends because I have no thyroid because of cancer my case is different I do not recommend asking others this and that see a good endocrinologist who really know the system and do some tests and take it from there that is what I do in my case and it is wise move no ask others everyone is totally different

My mom is on Levothyroxine and fainted on it. She suffered a concussion and severe trauma to the outer layer of the scalp, for lack of a better term. It was so frightening because she just went out like a light. She had no history of fainting and since being on Levothyroxine she's been no where near her usual self. She is elderly and I'm very upset this medication did such a thing. I can't let it happen again so we're going to the doctor tomorrow even though we were at the hospital two days ago over the concussion. Now we are following up. Hopefully this comment was helpful.
