Ciprofloxacin treats a wide variety of bacterial infections, including those involving the urinary tract, prostate, lower respiratory tract, sinuses and gastrointestinal tract, states RxList. Ciprofloxacin also treats skin, bone and joint infections. In addition, doctors prescribe ciprofloxacin to prevent anthrax infection in those who are exposed.
Ciprofloxacin is classified as a fluoroquinolone antibiotic, according to MedlinePlus. It is best for patients to continue taking ciprofloxacin even if their symptoms improve. Stopping ciprofloxacin too early can lead to a recurrent infection or cause the bacteria to become resistant to antibiotics. Ciprofloxacin sometimes causes side effects, such as stomach upset, heartburn, diarrhea, headache and vaginal itching or discharge.
