What the FAERS Data Reveals About pindolol Side Effects

The FDA Adverse Event Reporting System (FAERS) contains 774 voluntary reports linked to pindolol and its brand equivalents (Visken), spanning 2004 through 2025. Of those, 63 (8.1%) listed death as an outcome and 261 (33.7%) 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, 66% were female and 34% male; age distribution skews toward 75+, with 168 reports in that bracket. The single most reported reaction is drug ineffective with 51 submissions, followed by fatigue and nausea.

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.
