Cefpodoxime proxetil

What is this medication for?

• Skin infections (superficial pyoderma): Staph (intermedius/aureus/pseudintermedius), Strep. canis, E. coli, Proteus mirabilis, Pasteurella multocida
• Skin/soft tissue infections (susceptible organisms)

How is it given?

Give exactly as your veterinarian prescribed — never change the dose or stop on your own unless your veterinarian has told you to.

• Its labeled stopping logic is worth memorizing: treat 2–3 days BEYOND clinical resolution (max 28 days), and abandon if no response by day 3–4.

What if I miss a dose?

• Give it as soon as you remember — unless it is almost time for the next dose (then skip the missed one; never double up).
• Call your clinic if you miss more than one dose in a row.

Side effects — what should I watch for?

Effects listed as common in this handout

• stomach/intestinal upset (vomiting, diarrhea) (Primary effect)
• Hypersensitivity (Possible (cephalosporin class))

Worth a phone call to your veterinarian

• Any new symptom that worries you.

⚠️ Contact your veterinarian or an emergency clinic IMMEDIATELY if you notice

• Trouble breathing, collapse, seizures, severe vomiting or diarrhea, facial swelling, or pale gums

Before starting (or refilling), tell your veterinarian if your pet:

• has or has had: Cephalosporin/penicillin hypersensitivity
• has or has had: Renal disease — adjust; prolonged use invites resistance selection (see pearls)

• is pregnant, nursing, or used for breeding
• is taking any other medications, supplements, or flea/tick products, including:
  • Antacids/H2 blockers (human data)
  • Aminoglycosides
  • Bacteriostatic antibiotics

Storage and handling

Room temperature; tablets/film tabs.

Good to know

• Once-daily oral 3rd-gen ceph = the convenience trade: good staph/gram-negative skin coverage, but zero Pseudomonas/enterococcus/anaerobe/MRSA activity — culture when pyoderma recurs.
• Its labeled stopping logic is worth memorizing: treat 2–3 days BEYOND clinical resolution (max 28 days), and abandon if no response by day 3–4.
• Cefpodoxime-specific susceptibility disks required — 3rd-gen cephalosporin sensitivity doesn't transfer between agents.
• Overuse of oral 3rd-gen cephalosporins is a recognized ESBL/MRSA selection pressure in both human and veterinary practice — reserve for documented need.
