ABSTRACT
A 73-year-old female patient developed a generalized tonic-clonic seizure on the 6[th] day after treatment with moxifloxacin 400 mg daily intravenously for appendicitis. This patient had atrial fibrillation and history of a surgery for intracerebral hemorrhage, with impaired renal function and liver function, but without history of seizures. Moxifloxacin was discontinued and switched to cefuroxime. The patient remained seizure-free at discharge four days later. The naranjo adverse drug reaction probability scale score was 4, indicating a possible adverse reaction to moxifloxacin. The potential risk factors related to moxifloxacin-induced seizures are discussed. It highlights that pre-existing central nervous system disease, elderly female with lower bodyweight and severe renal impairment may be the risk factors involved in moxifloxacin-induced seizures
