What the FAERS Data Reveals About apremilast Side Effects

The FDA Adverse Event Reporting System (FAERS) contains 143,174 voluntary reports linked to apremilast and its brand equivalents (Otezla), spanning 2012 through 2025. Of those, 5,453 (3.8%) listed death as an outcome and 10,932 (7.6%) involved hospitalization. The most common indication reported alongside adverse events was Psoriasis.

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 45-64, with 40,417 reports in that bracket. The single most reported reaction is diarrhoea with 24,315 submissions, followed by nausea and psoriasis.

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.
