Is a Form 483 the same as a warning letter?

No. A 483 lists an inspector's observations at the close of an inspection. A warning letter is a later, more serious step taken by the agency when it concludes there are significant violations, often after an inadequate response to a 483.

Form FDA 483

In Oversight, quality & inspection

Also known as: 483, inspectional observations

A Form FDA 483 is the list of observations an FDA investigator leaves at the end of an inspection when they have seen conditions that may breach the law FDA enforces. It records the inspector's observations; it is not a final agency determination or a penalty. Organizations normally respond in writing with corrective actions, and a prompt, credible response matters a great deal.
