Data from the FDA Adverse Event Reporting System (FAERS), 2001 to 2025. A FAERS report records a temporal association, not proof of cause. See our methodology for how figures are compiled and de-duplicated.

The most commonly reported side effects of hydrocortisone come from 84,725 reports to the FDA, broken down here by frequency, patient demographics, and serious outcomes.

This page analyzes 84,725 reports to the FDA Adverse Event Reporting System (FAERS) for hydrocortisone (Cortef): the reactions reported most often, who reported them, serious outcomes such as hospitalization, and year-over-year trends. A FAERS report does not prove the drug caused the effect, and report volume tracks how widely a drug is used, not how likely an effect is for any one person. Educational information, not medical advice.

Of reports with known sex, 61% were female and 39% male; age distribution skews toward 45-64, with 17,968 reports in that bracket. The single most reported reaction is fatigue with 8,851 submissions, followed by pain and condition aggravated.

How to read these numbers

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. This page is for educational reference only and is not medical advice, speak with a licensed clinician about any side-effect concerns.
