I have taken Levenquin for years - so far nothing bad (at least that I have noticed). I have had cohn's, fibro, CFS, UTI, kidney stones, COPD (from having my immune system suppresed by crohn's treatments), diabetis (caused by Prednisone), high blood pressure alternating with very low bp (ranging from 234/142 down to 53/36), racing pulse then very low pulse (ranging from 156 down to 29 bpm) and some of these (pulse and BP) can be all in one day (both caused by Prednisone).
Thing is - I just turned 29. I have been dealing with these since I was 18 or so. I have often taken Levaquin with Prednisone and other antibotics.
The only thing that seems to concern me this time is extreme sweating - It is hot enough in the deep South without this med. I am noticing now that since the diabetis is under control (without meds now), I am very shaky and low sugars.
Also, if this causes racing pulse - I am in big trouble. I was given this med for a UTI, along with Prosed (which contains Atropine - from the Belladonna plant). Atropine was given to me in the hospital when I had the pulse crash of 29.
Just praying that I won't deal with any side effects like this.
Oh and I see insomnia- I am dealing with that enough now! If this is similar to Cipro - I should sleep well though LOL
