What the FAERS Data Reveals About vasopressin Side Effects

The FDA Adverse Event Reporting System (FAERS) contains 4,135 voluntary reports linked to vasopressin and its brand equivalents (Vasostrict), spanning 2004 through 2025. Of those, 1,633 (39.5%) listed death as an outcome and 2,378 (57.5%) 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, 42% were female and 57% male; age distribution skews toward 45-64, with 1,251 reports in that bracket. The single most reported reaction is drug ineffective with 1,262 submissions, followed by off label use and hypotension.

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.
