If I read correctly, Cipro (
ciprofloxacin) is a fluoroquinolone, in the same family as levaquin, if that's useful data. Biggest downside risk seems to be risk of tendon rupture. rxlist ******* has the usual hideous rundown of possible side effects if you're so inclined.
oh, and it slows clearance of caffeine?
think about calling your Lyme doc about the reaction you are having, just to be sure it makes sense to continue with cipro. Not like there aren't other abx out there.
