Cefepime is Not Available in Oral Formulation
No, there is no oral version of cefepime available. Cefepime is only available as an intravenous (IV) or intramuscular (IM) formulation for parenteral administration 1.
Administration Routes for Cefepime
Cefepime is a fourth-generation cephalosporin that can only be administered through:
- Intravenous (IV) infusion (most common)
- Intramuscular (IM) injection
The pharmacokinetic properties of cefepime necessitate parenteral administration:
- It has limited oral bioavailability
- It is primarily eliminated via renal excretion as unchanged drug 2
- Its elimination half-life is approximately 2-2.5 hours 2
Oral Alternatives When Switching from IV Cefepime
When transitioning from IV cefepime to oral therapy (IV-to-PO switch), several alternatives may be considered based on the infection being treated:
For Febrile Neutropenia:
- First choice: Ciprofloxacin plus amoxicillin-clavulanate for adults 1, 3
- For children: Cefixime has been studied as an oral step-down therapy 1, 3
For Respiratory Infections:
- Amoxicillin-clavulanate
- Fluoroquinolones (levofloxacin, moxifloxacin)
- Oral cephalosporins (cefuroxime axetil, cefpodoxime proxetil, cefdinir) 1
For Other Infections:
- Selection should be based on culture results, local antibiogram data, and the specific pathogens being targeted
Important Clinical Considerations
Patient eligibility: Only switch to oral therapy when the patient shows clinical improvement and is hemodynamically stable
Spectrum coverage: Ensure the oral alternative covers the same pathogens as cefepime
Bioavailability: Consider the bioavailability of oral alternatives when determining dosing
Resistance patterns: Local antibiogram data should guide selection of appropriate oral therapy
Common Pitfalls to Avoid
- Inadequate spectrum coverage: Cefepime has broader spectrum than most oral antibiotics, particularly against Pseudomonas and resistant Enterobacterales
- Premature switch: Switching too early before clinical improvement may lead to treatment failure
- Inappropriate oral agent selection: Failing to match the oral agent's spectrum to the suspected or confirmed pathogen
When IV cefepime is required but oral therapy is preferred, consultation with an infectious disease specialist may be warranted to determine the most appropriate oral alternative based on the specific clinical scenario.
