What the FDA Data Shows for cefpodoxime

The FDA label for cefpodoxime (sold under brand names such as Vantin) classifies it as a prescription-only medication in the Third-Generation Cephalosporin class. Cefpodoxime treats mild to moderate infections caused by certain bacteria. Official labeling lists 6 commonly reported side effects, including Diarrhea, Nausea, Vaginal fungal infections.

Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. Voluntary reports accumulate over the lifetime of a drug and reflect wide-ranging clinical use. The database also lists 1 documented drug interaction derived from FDA labeling, with the top-flagged interaction rated minor severity. NADAC pricing from CMS shows a generic unit cost of $1.08.

Report counts do not establish causation — a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information further shape supply and switching decisions.
