The observations are based on evidence gathered during the inspection, and the investigator discusses them with the company at the closing meeting. FDA recommends a written response within 15 business days, which is generally the window in which a response is considered before FDA decides on further action. Not every 483 leads to enforcement, but an inadequate or missing response can lead to a warning letter.

Why it matters for labeling

Labeling appears in 483s as labeling control and packaging findings, such as mix-ups, uncontrolled labeling and missing review records, and increasingly as computerized system and data integrity findings, such as audit trails that don't capture changes or approvals that can't be tied to a version. A response needs evidence, so the review records have to exist and be retrievable.

Common mistakes

  • A late or generic response that doesn't address the root cause
  • Promising corrective actions without a timeline or evidence
  • Fixing the single label without looking at the process behind it
  • Not checking other products for the same finding
