Cefpodoxime

Cefpodoxime Proxetil is approved to treat a wide range of mild to moderate bacterial infections in adults, adolescents, and children. Dosing, duration, and eligible age groups vary by infection.

• Ear infections (acute otitis media) — Cefpodoxime Proxetil oral suspension is approved for infants and children aged 2 months through 12 years
• Strep throat and tonsillitis (pharyngitis/tonsillitis) — approved for both adults/adolescents and children aged 2 months through 12 years
• Community-acquired pneumonia — approved for adults and adolescents
• Acute bacterial exacerbation of chronic bronchitis — approved for adults and adolescents; note that effectiveness against certain beta-lactamase-producing strains of H. influenzae has not been established
• Acute maxillary sinusitis — approved for adults, adolescents, and children aged 2 months through 12 years
• Uncomplicated skin and skin structure infections — approved for adults and adolescents; abscesses may also need surgical drainage
• Uncomplicated urinary tract infections (cystitis) — approved for adults and adolescents; note that some other antibiotic classes may have higher bacterial eradication rates
• Uncomplicated gonorrhea — Cefpodoxime Proxetil tablets treat uncomplicated urethral and cervical gonorrhea in men and women, and uncomplicated ano-rectal infections in women; not shown effective for pharyngeal gonorrhea or for rectal gonorrhea in men

Cefpodoxime is a bactericidal antibiotic — it kills bacteria by blocking their ability to build their outer cell wall. Bacteria need this wall to survive and maintain their structure. Without it, they break down and die. This makes cefpodoxime effective against a broad range of bacteria that cause common infections.

Cefpodoxime also retains activity in the presence of certain bacterial enzymes called beta-lactamases — enzymes that some bacteria produce specifically to destroy antibiotics. This helps cefpodoxime work against some strains of bacteria that resist other antibiotics.

Cefpodoxime Proxetil is taken by mouth in either tablet or oral suspension form. It is generally taken twice a day, though some infections may call for a single dose or a different schedule — always follow your prescriber's specific instructions.

• Tablets: Take with food to improve absorption. Recommended for adults and adolescents (age 12 and older).
• Oral suspension: Can be taken with or without food; food does not significantly affect the total amount absorbed, though it may slow the rate slightly. Recommended for infants and children aged 2 months through 12 years, and also available for adults.
• If you miss a dose, take it as soon as you remember — but skip it if it's almost time for your next dose. Never double up.
• Finish the entire course of treatment, even if you feel better before it's done.

The most common side effects of cefpodoxime involve the digestive system.

• Diarrhea or loose stools (most common; more likely at higher doses)
• Nausea
• Vomiting
• Stomach pain or discomfort
• Headache
• Vaginal yeast infections
• Skin rash
• Diaper rash or fungal skin rash (particularly in infants and toddlers)

Seek medical attention right away if you develop severe or bloody diarrhea, signs of a serious allergic reaction (difficulty breathing, swelling, severe rash with blistering), or yellowing of the skin or eyes — these are signs of potentially serious reactions that need prompt care.

• Serious allergic reactions: Cefpodoxime can cause severe allergic reactions, including anaphylaxis (a life-threatening response). If you've ever reacted to a cephalosporin or penicillin antibiotic, tell your doctor before starting this medication. Up to 10% of people with a penicillin allergy may also react to cephalosporins.
• C. difficile-associated diarrhea (CDAD): Like all antibiotics, cefpodoxime can disrupt the normal gut bacteria and allow C. difficile (a harmful bacterium) to overgrow, causing anything from mild diarrhea to a serious, life-threatening colon infection. This can happen during treatment or even weeks after finishing it. Report persistent or severe diarrhea to your doctor immediately.
• Serious skin reactions: Rare but severe skin reactions — including Stevens-Johnson syndrome and toxic epidermal necrolysis (widespread skin blistering and peeling) — have been reported. Stop the drug and get emergency care if this happens.
• Seizures: Cephalosporin-class antibiotics have been linked to seizures, particularly in patients with kidney impairment who do not have their dose adjusted appropriately.
• Liver effects: Acute liver injury has been reported in post-marketing experience. Seek care if you notice yellowing of the skin or eyes, dark urine, or unusual fatigue.

Several medications and substance types can affect how cefpodoxime is absorbed or cleared from the body.

• High-dose antacids (e.g., sodium bicarbonate, aluminum hydroxide): Reduce absorption of cefpodoxime — take at a different time if possible
• H2 blockers (acid-reducing drugs like famotidine or ranitidine): Reduce the amount of cefpodoxime absorbed — timing matters
• Probenecid (gout medication): Slows the kidneys' removal of cefpodoxime, raising drug levels in the blood — tell your prescriber if you take it
• Anticholinergic drugs (e.g., propantheline): Delay absorption of cefpodoxime, though overall absorption is not affected
• Nephrotoxic drugs (medications that can harm the kidneys): Kidney function should be monitored closely if used together with cefpodoxime

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

• Tell your doctor if you are allergic to cefpodoxime or any other cephalosporin antibiotic (such as cephalexin, cefdinir, or cefuroxime)
• Tell your doctor about any penicillin allergy — a cross-reaction is possible
• Tell your doctor if you have kidney problems — the dose may need to be adjusted for severe impairment
• Tell your doctor if you are pregnant or planning to become pregnant; post-marketing reports have noted in utero exposure associated with miscarriage
• Tell your doctor about all medications you take, especially antacids, acid-reducing drugs, probenecid, or any kidney-affecting medications
• Cefpodoxime Proxetil oral suspension is approved for infants as young as 2 months old; follow weight-based dosing carefully in children

Taking too much cefpodoxime may cause nausea, vomiting, stomach upset, and diarrhea. In the event of a serious overdose, particularly in someone with kidney problems, hemodialysis or peritoneal dialysis may help remove the drug from the body. Contact Poison Control or seek emergency care if you suspect an overdose.

Cefpodoxime kills bacteria by preventing them from building their cell walls — a process bacteria need to survive and replicate. It is active against both gram-positive and gram-negative bacteria and can work even in the presence of some bacterial enzymes (beta-lactamases) that normally break down antibiotics. After dosing, drug levels in tissues including tonsils, lungs, and skin blister fluid reach concentrations that exceed the levels needed to inhibit the key bacteria these infections target.

Cefpodoxime proxetil is a prodrug — your body converts it into its active form, cefpodoxime, after it is absorbed from the gut. Roughly 50% of the dose reaches the bloodstream when taken on an empty stomach; taking the tablet with food boosts absorption noticeably, though food has less effect on the oral suspension. Peak blood levels occur about 2–3 hours after a tablet dose. The drug has a short half-life of roughly 2 to 2.8 hours and is cleared primarily through the kidneys, with about 29–33% excreted unchanged in the urine within 12 hours. Very little of the drug is broken down by the body itself.
