Abstract:
Cefepime is a fourth-generation cephalosporin widely used to treat gram-positive and gram-negative infections. Its half-life is approximately two hours in patients with normal renal function and may increase to 13.5 hours in patients with acutely or chronically impaired renal function. Although dosage adjustment is recommended for patients with renal insufficiency to prevent drug accumulation, toxicity has been reported in patients even with normal renal function. One underreported complication of cefepime toxicity is cefepime-induced encephalopathy (CIE). While the pathophysiology is unclear, treatment involves early discontinuation of this antibiotic to decrease morbidity and mortality. We report five cases of cefepime-induced encephalopathy occurring within one year at a single institution.
Insights
Cefepime antibiotic can cause brain issues, known as cefepime-induced encephalopathy (CIE), even in patients with normal kidney function. Early antibiotic discontinuation is key to reducing harm.
Area of Science:
- Pharmacology
- Neurology
- Infectious Diseases
Background:
- Cefepime, a fourth-generation cephalosporin, is broadly effective against gram-positive and gram-negative bacteria.
- While generally safe, cefepime can accumulate in patients with impaired renal function, increasing toxicity risk.
- Cefepime-induced encephalopathy (CIE) is an underreported neurological complication of cefepime toxicity.

Introduction to Documentation and Reporting
Nursing documentation records essential information and details regarding a patient's care and treatment in written or electronic form. It is a critical aspect of nursing practice that involves documenting assessments, interventions, outcomes, and other relevant details about a patient's health status.
Documentation maps the patient's health journey by creating a comprehensive...
