Ceftaroline-associated Encephalopathy in Patients With Severe Renal Impairment.

Encephalopathy complicates beta-lactam therapy, particularly with impaired renal function, though no studies have reported ceftaroline-associated encephalopathy. Among 28 patients with estimated glomerular filtration rates <30 mL/min who received ≥5 days of ceftaroline, 3 developed encephalopathy. Ceftaroline, when dosed supra-therapeutically for serious infections, may be a cause of antibiotic-associated encephalopathy.
