Too much Levothyroxine?

[Sasa888]

Hi, I started about a month or so ago on this as I have an underactive thyroid gland, I had just 25mg at first which I couldn't see a different with, then a couple of weeks back or maybe a week I can't remember (!) doc raised it to 75mg - she was going to do 50 but said she wanted me to notice a difference. Well I'm not sure if it's linked but I have had terrible pressure in my head for days now, gets worse in the evening and also giving me panic attacks for no reason. My throat keeps feeling really closed up, and the head thing is ridiculous. It's not a pain, it's like a crushing feeling. It's so tight I can't concentrate. Even trying to relax it doesn't work it's so tense, and painkillers do nothing as it's not painful.. Do you think my dose could be too high? Oh and also the head thing is making my ears blocked and my vision is not right. Bit blurred..

I would call the dr and tell her what you are feeling.  I started on 50 mgs and after 2 months was increased to 75 mgs.  I think the jump from 25 to 75 may be too much for you to handle at one time.  My endo wants me to take the max. I can tolerate, but will find that dosage in gradule increases.

it's possible that the jump has just been too much, too soon. I know that about a week after every dose increase i've had my headaches get worse for a while and that is after small jumps e.g 25mcg - 50mcg
