Could you tell me what are normal side effects when using cipro (ciprofloxacin)?

Cipro (ciprofloxacin) When people think about cipro, (ciprofloxacin) the one side effect that quickly comes to mind is tendon rupture. Ciprofloxacin belongs to a class of antibiotics called fluoroquinolones, and they all have that danger. Other side effects could include diarrhea, skin reaction, seizures amongst other things. I'm sure their website would have a more complete list of possible side effects.
