US FDA Form 483 and Warning Letter Analysis, Response and Recovery

On this page:

  • What is a FDA Form 483 and how to respond
  • How Emergo can help you recover from a FDA 483 or Warning Letter

No medical device or IVD manufacturer wants to receive a Form 483 or Warning Letter from the US Food and Drug Administration (FDA). Officially, the FDA Form 483 is referred to as "Notice of Inspectional Observations," commonly referred to simplay as a "483." The 483 is issued at the conclusion of an on-site inspection if the FDA field investigator observed deficiencies in your quality system or conditions which may violate the Food, Drug, or Cosmetic Act.

You must respond to the 483 promptly and identify your course of action to correct the findings within a timeframe specified by the FDA. A detailed response for each item addressed in the 483 will also be required. The quality and promptness of your response to this letter are extremely important.

The field inspector will submit the final 483 to his/her superiors; and, if the findings are serious enough, or if the response to the 483 is deemed insufficient, an FDA Warning Letter may be issued to your firm. A Warning Letter is the FDA’s advisory notice that you have significantly violated FDA regulations.  It will identify the violation(s), and make it clear that you must correct the problems and inform FDA of your specific plans for correction of the problem, including actions to prevent it or a similar problem from re-occurring. The FDA will check back to ensure that the corrections are adequate.
