What Is An FDA 483 Observation? An FDA 483 observation, or “inspectional observation,” is a notice sent by the FDA to highlight any potential regulatory violations found during a routine inspection. This can relate to the company's facility, equipment, processes, controls, products, employee practices, or records.

The FDA typically requires Phase 1, 2, and 3 trials to be conducted to determine if the drug or device can be approved for further use. If researchers find the intervention to be safe and effective after the first three phases, the FDA approves it for clinical use and continues to monitor its effects.

Examples of recently issued 483s are available in ORA's Electronic Reading Room. Questions regarding Inspection Observations may be directed by email to FDAInspectionsObservations@fda.hhs.gov.

A: An FDA Form 483 is issued to firm management at the conclusion of an inspection when an investigator(s) has observed any conditions that in their judgment may constitute violations of the Food Drug and Cosmetic (FD&C) Act and related Acts.

Warning Letters are issued for violations of regulatory significance that may lead to enforcement action if not promptly and adequately corrected. A Warning Letter is the agency's principal means of achieving prompt voluntary compliance with the Federal Food, Drug, and Cosmetic Act (the Act).

The FDA Form 483 does not constitute a final agency determination and firms are encouraged to respond to the FDA Form 483 in writing with their corrective action plan with supporting documentation within 15 business days from the issuance of the FDA Form 483 and implement the corrective action plan expeditiously.

To protect “confidential corporate information,” the FDA routinely redacts information in warning letters, using (b)(4) to indicate where information has been blacked out.
