Avelox is extremely dangerous. I took it and ended up with nerve damage, vasculitis, tendinopathy, GI issues, and other problems. I lost 30 pounds in one month and had to go to physical therapy for 4 months to recover. I racked up 30k in medical bills thanks to this medication (insurance covered it).
Floroquinolones are chemo-therapy, not antibiotics, and their side-effects can be fatal.
