This page analyzes 262,453 reports to the FDA Adverse Event Reporting System (FAERS) for ibuprofen (Advil): the reactions reported most often, who reported them, serious outcomes such as hospitalization, and year-over-year trends.

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. This page is for educational reference only and is not medical advice, speak with a licensed clinician about any side-effect concerns.
