What the FAERS Data Reveals About ofloxacin Side Effects
The FDA Adverse Event Reporting System (FAERS) contains 7,063 voluntary reports linked to ofloxacin and its brand equivalents (Floxin, Ocuflox), spanning 1999 through 2025. Of those, 597 (8.5%) listed death as an outcome and 2,611 (37.0%) 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, 54% were female and 46% male; age distribution skews toward 45-64, with 1,398 reports in that bracket. The single most reported reaction is drug ineffective with 345 submissions, followed by eye pain and off label use.
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.
