What the FAERS Data Reveals About zolpidem Side Effects

The FDA Adverse Event Reporting System (FAERS) contains 131,653 voluntary reports linked to zolpidem and its brand equivalents (Ambien), spanning 2001 through 2025. Of those, 15,695 (11.9%) listed death as an outcome and 45,304 (34.4%) 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, 64% were female and 36% male; age distribution skews toward 45-64, with 37,070 reports in that bracket. The single most reported reaction is drug ineffective with 8,550 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.
