A CAPA starts with a described problem, finds the root cause, assigns corrective actions (to fix the issue) and preventive actions (to stop it recurring, including in similar products or processes), and ends with a check that the actions worked. It is a core part of quality systems for medical devices (ISO 13485, which FDA's QMSR now incorporates) and is expected for medicines, where FDA requires investigation of discrepancies (21 CFR 211.192) and ICH Q10 describes CAPA as part of the pharmaceutical quality system.
Why it matters for labeling
A labeling error caught before release, or after, should lead to a deviation and often a CAPA. The strongest CAPAs go beyond the single label: they ask why the process allowed the error, for example a final check made against the previous draft instead of the approved master, and fix that. A CAPA that ends with "retrain the reviewer" tends to repeat.
Common mistakes
- Naming human error as the root cause and stopping there
- Corrective action without preventive action
- No effectiveness check, so the CAPA is closed when the corrected label is printed
- Not checking other products, markets and language versions for the same problem
