Hi Debra,
Welcome to LADVT, some doctors are going to tell you that anticoags don't have any side effects, THOSE are the Dr or nurse I worry about.
I say that they do have them and they interact differently with everybody.
After being on and off warfarin so many times I could feel the side effects start and stop each time.
When I was on Warfarin, I would always be cold, in a fog, forgetful, moody and yes starting to sound like a woman describing her period. (I know, not a pretty picture, but this was all the time)
Warfarin was the only prescription I was on and when I switched to Pradax or Tinzaparin or Fragmin THESE SIDE EFFECTS would COMPLETELY vanish, so I have to disagree with your coag nurse's assessment...
