What the FAERS Data Reveals About alprazolam Side Effects
The FDA Adverse Event Reporting System (FAERS) contains 200,719 voluntary reports linked to alprazolam and its brand equivalents (Xanax), spanning 2001 through 2025. Of those, 32,899 (16.4%) listed death as an outcome and 64,280 (32.0%) 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, 67% were female and 32% male; age distribution skews toward 45-64, with 54,477 reports in that bracket. The single most reported reaction is drug ineffective with 13,399 submissions, followed by nausea and fatigue.
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.
