Drug Guide

Generic Name

Cefepime Hydrochloride

Brand Names Maxipime, Cefepime In Plastic Container, Cefepime And Dextrose In Duplex Container, Cefepime Hydrochloride In Plastic Container

Classification

Therapeutic: Antibiotic, Broad-spectrum cephalosporin

Pharmacological: Beta-lactam antibiotic

FDA Approved Indications

  • Treatment of severe bacterial infections caused by susceptible organisms, including pneumonia, febrile neutropenia, urinary tract infections, skin and soft tissue infections, intra-abdominal infections, and meningitis.

Mechanism of Action

Cefepime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins, leading to cell lysis and death. It is resistant to many beta-lactamases, providing broad-spectrum activity.

Dosage and Administration

Adult: Typically 1-2 g every 8-12 hours intravenously, dosage adjusted based on infection severity and renal function.

Pediatric: Dosing varies; generally 50-100 mg/kg/day divided every 8-12 hours, adjusted for renal function.

Geriatric: Use with caution; start at lower doses due to decreased renal function.

Renal Impairment: Dose adjustments required, based on creatinine clearance.

Hepatic Impairment: No specific adjustment necessary.

Pharmacokinetics

Absorption: Administered IV; not absorbed orally.

Distribution: Widely distributed, including cerebrospinal fluid (CSF).

Metabolism: Minimal hepatic metabolism; primarily excreted unchanged.

Excretion: Renal excretion via glomerular filtration and tubular secretion.

Half Life: Approximately 2 hours in patients with normal renal function.

Contraindications

  • Known hypersensitivity to cefepime or other cephalosporins.

Precautions

  • Use cautiously in patients with allergies to penicillin or other beta-lactam antibiotics.

Adverse Reactions - Common

  • Pain at injection site (Common)
  • Rash (Common)
  • Headache (Common)

Adverse Reactions - Serious

  • Anaphylaxis (Rare)
  • Seizures (Rare, increased risk in renal impairment)
  • Clostridioides difficile-associated diarrhea (Rare)

Drug-Drug Interactions

  • Probenecid (may increase cefepime levels).
  • Aminoglycosides (potential nephrotoxicity).

Nursing Implications

Assessment: Monitor renal function, electrolyte balance, and for allergic reactions.

Diagnoses:

  • Risk for allergic reaction
  • Risk for infection related to antibiotic therapy
  • Impaired skin integrity at injection site

Implementation: Administer IV as prescribed; monitor for adverse reactions; adjust dose in renal impairment.

Evaluation: Assess infection resolution, monitor labs, and watch for side effects.

Patient/Family Teaching

  • Complete full course of therapy.
  • Report any signs of allergic reaction or unusual side effects.
  • Inform about possible diarrhea and to seek medical attention if severe or persistent.

Special Considerations

Black Box Warnings:

  • Risk of hypersensitivity reactions, including anaphylaxis.

Genetic Factors: None specified.

Lab Test Interference: May cause false elevations in urine glucose testing with some methods.

Overdose Management

Signs/Symptoms: Neurotoxicity including seizures, confusion, and coma in severe overdose.

Treatment: Supportive care; no specific antidote; consider dialysis in severe cases.

Storage and Handling

Storage: Store at room temperature 20-25°C (68-77°F). Protect from light.

Stability: Stable under recommended storage conditions; discard after expiration.
