How the dose is calculated
Cefpodoxime is dosed in mg/kg/day divided every 12 hours. Standard dosing covers most uncomplicated infections; the higher-dose regimen is used for more severe skin/soft-tissue infections.
Typical dosing by indication
| Indication | Dose | Frequency | Max |
|---|---|---|---|
| Standard | 10 mg/kg/day | every 12h (2×/day) | 400 mg/day |
| Higher-dose | 16 mg/kg/day | every 12h (2×/day) | 800 mg/day |
Clinical use
- Cefpodoxime is a third-generation oral cephalosporin with broader Gram-negative activity than first-generation agents, making it a useful oral option for otitis media, sinusitis, and uncomplicated UTI.
- Absorption is improved when taken with food — worth noting for patients reporting reduced effect on an empty stomach.
- Not reliably active against Pseudomonas or MRSA — narrower coverage than injectable third-generation agents like ceftriaxone or cefotaxime.
- Requires dose-interval adjustment in significant renal impairment.
Frequently asked questions
What is cefpodoxime used for?
Cefpodoxime is an oral third-generation cephalosporin commonly used for otitis media, sinusitis, uncomplicated urinary tract infections, and some skin infections.
Should cefpodoxime be taken with food?
Yes — taking it with food improves absorption, so it's generally recommended to give doses with a meal.
Is cefpodoxime effective against MRSA or Pseudomonas?
No — cefpodoxime does not reliably cover methicillin-resistant Staphylococcus aureus (MRSA) or Pseudomonas aeruginosa; a different agent is needed if either is suspected.
How does cefpodoxime compare to amoxicillin?
Cefpodoxime has broader Gram-negative coverage than amoxicillin and can be an alternative when a beta-lactamase-producing organism is suspected, though amoxicillin (or amoxicillin-clavulanate) remains first-line for most routine infections.
