FAERS reports

Data from the FDA Adverse Event Reporting System (FAERS), 2004 to 2025. A FAERS report records a temporal association, not proof of cause. See our methodology for how figures are compiled and de-duplicated.

The most commonly reported side effects of cefepime come from 13,667 reports to the FDA, broken down here by frequency, patient demographics, and serious outcomes.

This page analyzes 13,667 reports to the FDA Adverse Event Reporting System (FAERS) for cefepime (Maxipime): the reactions reported most often, who reported them, serious outcomes such as hospitalization, and year-over-year trends. A FAERS report does not prove the drug caused the effect, and report volume tracks how widely a drug is used, not how likely an effect is for any one person. Educational information, not medical advice.

What the FAERS Data Reveals About cefepime Side Effects

The FDA Adverse Event Reporting System (FAERS) contains 13,667 voluntary reports linked to cefepime and its brand equivalents (Maxipime), spanning 2004 through 2025. Of those, 2,974 (21.8%) listed death as an outcome and 8,120 (59.4%) involved hospitalization. The most common indication reported alongside adverse events was Product Used For Unknown Indication.

Demographic breakdowns help contextualize who is being exposed to the drug. Of reports with known sex, 44% were female and 55% male; age distribution skews toward 45-64, with 3,924 reports in that bracket. The single most reported reaction is acute kidney injury with 1,130 submissions, followed by pyrexia and pneumonia.

How to read these numbers

FAERS is a signal-detection tool, not a scorecard. Reports are voluntary, and a single case may list multiple suspect drugs, so numbers above should not be read as incidence rates or per-patient risk. Widely prescribed drugs naturally accumulate more reports than niche therapies even when individual risk is low. These aggregates are useful for spotting patterns that merit further pharmacovigilance, not for choosing between medications.
