I'm trying to puzzle out why my system seems over sensitive to so many medicines. I'm not allergic to them but experience such significant side effects that I stop taking them- usually a fast pounding heartbeat. I did ask my GP about it and she just said 'oh, some people are just more sensitiv,e than others'. Another clue, perhaps, is that the endocrinologist says I lack an enzyme which allows other people to turn levothyroxine into the active form of thyroid hormone - so I take a different kind of thyroid hormone.
The thing is, it seriously limits the drugs I can take, including one or two which would fend off problems in the future if I could take them.
Is this a fibro thing which others recognise, or just a me thing?
