Ceftriaxone-induced encephalopathy is a rare but known adverse effect secondary to neurotoxicity, especially in patients with end-stage renal disease (ESRD) on hemodialysis. The common presenting symptoms include myoclonus, psychosis, and seizures. We are presenting a case of a 77-year-old female patient who presented with confusion and jerky movements of her lips and extremities. Her initial workup was negative for stroke and seizure disorder. A probable diagnosis of ceftriaxone-induced encephalopathy was made using an Adverse Drug Reaction (ADR) probability scale (Naranjo scale) with a Naranjo score of 5. The patient's symptoms resolved after discontinuation of ceftriaxone. Ceftriaxone is a commonly used intravenous antibiotic in the inpatient setting, and thus clinicians should be aware of this rare adverse reaction in patients with ESRD.
Keywords: acute metabolic encephalopathy; drug-induced encephalopathy; hemodialysis related; iv ceftriaxone; prolonged antibiotics.
