Ciprofloxacin is an antibiotic that is used to help cure bacterial infections, according to the Mayo Clinic. The Mayo Clinic notes that ciprofloxacin is also used to treat anthrax infections.
MedicineNet reports that ciprofloxacin is used in the treatment of infections of the skin, bones, joints, lungs and airways. Doctors also often prescribe it to treat urinary tract infections, diarrhea and intra-abdominal infections, according to MedicineNet. MedicineNet notes that patients take it orally by suspension or tablet, or doctors can inject it.
RxList notes that ciprofloxacin belongs to a class of drugs that is linked to an increased risk of tendinitis and tendon rupture. This is a particular problem for patients over the age of 60, patients who take corticosteroid drugs, and patients who have had heart, lung or kidney transplants, according to RxList.
