What the FAERS Data Reveals About ziprasidone Side Effects

The FDA Adverse Event Reporting System (FAERS) contains 17,328 voluntary reports linked to ziprasidone and its brand equivalents (Geodon), spanning 2004 through 2025. Of those, 1,171 (6.8%) listed death as an outcome and 4,189 (24.2%) involved hospitalization. The most common indication reported alongside adverse events was Bipolar Disorder.

Demographic breakdowns help contextualize who is being exposed to the drug. Of reports with known sex, 61% were female and 38% male; age distribution skews toward 18-44, with 4,204 reports in that bracket. The single most reported reaction is drug ineffective with 1,350 submissions, followed by weight increased and diabetes mellitus.

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.
