Background: The development of factor V inhibitor is very rare, especially in combination with antiphospholipid antibodies. Case Report: The paper describes the course of two patients with factor V inhibitor, antiphospholipid antibodies and massive bleeding symptoms after treatment with ciprofloxacin. At that time, ciprofloxacin was the only new drug given. Diagnosis and Clinical Course: First changes of the coagulation system were detected 4 days after start of treatment. In one case, occurrence was transient, and normalization was observed after terminating ciprofloxacin treatment. The other case ended with massive muscular and visceral bleedings and cardiovascular failure. Factor V inhibitor and antiphospholipid antibodies could be demonstrated even after termination of ciprofloxacin therapy. Conclusion: The association of treatment with ciprofloxacin and development of factor V inhibitor and antiphospholipid antibodies is probably diagnosed to rarely. These two cases emphasize the necessity of meticulous clarification of a prolonged activated partial thromboplastin time (aPTT) and a drop in prothrombin time (PT) during and after ciprofloxacin treatment.
