Cefpodoxime vs Amoxicillin‑Clavulanate: Dosing Recommendations

Standard Dosing Regimens

Adults – Cefpodoxime proxetil: 200 mg to 400 mg administered twice daily (every 12 h). [American Academy of Otolaryngology–Head and Neck Surgery] [1]
Children – Cefpodoxime proxetil: 5 mg/kg twice daily, not exceeding a total dose of 200–400 mg per administration. [American Academy of Otolaryngology–Head and Neck Surgery] [1]
Adults – Amoxicillin‑Clavulanate (standard formulation): 500 mg to 875 mg administered three times daily. [Infectious Diseases Society of America] [4]
Children – Amoxicillin‑Clavulanate (standard formulation): dose varies by preparation but is generally given three times daily. [American Academy of Otolaryngology–Head and Neck Surgery] [2]

Shared therapeutic indications: Both agents are appropriate first‑line options for acute respiratory tract infections, acute otitis media, and acute bacterial rhinosinusitis. [American Academy of Otolaryngology–Head and Neck Surgery; American Thoracic Society] [1][2][3]6
Guideline preference: Amoxicillin‑Clavulanate enjoys broader first‑line endorsement for many respiratory infections, reflecting its inclusion in major infectious‑disease and pulmonary guidelines. [Infectious Diseases Society of America; American Thoracic Society] [4]6
Pediatric acute bacterial rhinosinusitis: Both cefpodoxime (twice daily) and amoxicillin‑clavulanate (three times daily) are listed as acceptable initial therapies. [American Academy of Otolaryngology–Head and Neck Surgery] [2]3

Pediatric sinusitis without recent antibiotic exposure: The American Academy of Otolaryngology–Head and Neck Surgery recommends either cefpodoxime proxetil twice daily or amoxicillin‑clavulanate three times daily (standard formulation). [2][3]
Community‑acquired pneumonia in adults with comorbidities: The American Thoracic Society lists amoxicillin‑clavulanate three times daily as a primary option, with cefpodoxime 200 mg twice daily offered as an alternative regimen. 6
Dosing frequency stability: Current guidelines from both the American Academy of Otolaryngology–Head and Neck Surgery and the American Thoracic Society explicitly advise against altering the approved dosing intervals for either antibiotic. [2][3]6
