FDA category + note

Mechanism

Cefepime, a fourth-generation cephalosporin, exhibits an extended spectrum of activity compared to third-generation agents. It possesses increased stability against hydrolysis by plasmid and chromosomally mediated β-lactamases.

Indications

Infections due to sensitive Gram-positive and Gram-negative bacteriaMild to moderate urinary tract infectionsMild to moderate infections due to sensitive Gram-positive and Gram-negative bacteriaSevere infections due to sensitive Gram-positive and Gram-negative bacteriaResistant pseudomonas infections where first-line agents are not effective or contra-indicatedNosocomial infections: pneumonia, meningitis, urinary tract infections, intra-abdominal infections

Dosing

Adult: Mild to moderate urinary tract infections (body-weight 41 kg and above): 0.5–1 g every 12 hours by intravenous injection, intravenous infusion, or intramuscular injection. Mild to moderate infections (body-weight 41 kg and above): 1 g every 12 hours by intravenous injection, intravenous infusion, or intramuscular injection.…
Pediatric: Body-weight up to 41 kg: 50 mg/kg every 12 hours (max. per dose 2 g), increased if necessary to 50 mg/kg every 8 hours (max. per dose 2 g) for severe infections, intravenous route preferred in severe infections.
Renal adjustment: Manufacturer advises reduce dose—consult product literature.
Max dose: 2 g

Lactation

Manufacturer advises caution—present in milk in very low quantities.

Drug interactions

Mycophenolate Mofetil

Moderate

Database

Decreased plasma concentrations of mycophenolic acid, potentially leading to reduced immunosuppressive effect and increased risk of transplant rejection.

Monitor mycophenolic acid levels (if available) and clinical signs of rejection. Consider increasing mycophenolate mofetil dose if clinically indicated. This interaction is more pronounced with prolonged antibiotic use.

Probenecid

Moderate

Database

Increased and prolonged plasma concentrations of cefepime, potentially leading to increased risk of dose-dependent adverse effects such as neurotoxicity (seizures, encephalopathy).

Consider reducing the cefepime dose if co-administering with probenecid, especially in patients with renal impairment. Monitor for signs of neurotoxicity.
