What Is Adverse Event Reporting?

The mandatory reporting to the FDA of any serious adverse event associated with a dietary supplement. Under the Dietary Supplement and Nonprescription Drug Consumer Protection Act, manufacturers must report serious adverse events within 15 business days.

Why It Matters for Supplement Brands

Failing to report serious adverse events is a federal crime. Beyond legal compliance, adverse event data is critical for product safety monitoring and can provide early warning signals about ingredient interactions, contamination, or dosage issues.

How It Works

A 'serious adverse event' is one that results in: • Death • A life-threatening experience • Inpatient hospitalisation • A persistent or significant disability • A congenital anomaly or birth defect • An event requiring medical or surgical intervention to prevent one of the above

Reporting process: 1. **Consumer complaint**: A consumer reports the adverse event to the manufacturer (directly or through a retailer). 2. **Assessment**: The manufacturer evaluates whether the event meets the 'serious' threshold. 3. **Filing**: Serious adverse events must be reported to the FDA via MedWatch Form 3500A within 15 business days. 4. **Record retention**: Records of all adverse events (serious and non-serious) must be maintained for 6 years.

Common Mistakes to Avoid

  • Not having a system in place to receive and evaluate consumer adverse event reports
  • Misclassifying a serious adverse event as non-serious to avoid reporting obligations
  • Failing to train customer service staff to recognise and escalate potential adverse events
  • Not maintaining the required 6-year retention of adverse event records
