Before taking ciprofloxacin, tell your doctor if you have a heart rhythm disorder, kidney or liver disease, joint problems, diabetes, muscle weakness or trouble breathing, a history of seizures, low levels of potassium in your blood, a personal or family history of Long QT syndrome, or if you have ever had an allergic reaction to an antibiotic.
