What are FDA Form 483 Observations?

An FDA Form 483 Observation, also referred to as “inspectional observation” or “Form 483” is sent by the FDA to highlight any potential regulatory violations found during a routine inspection. An FDS Form 483 Observation can relate to the company’s facility, equipment, processes, controls, products, employee practices, or records.

While an FDA Form 483 is not final determination on regulation violations, they are cause for concern and need to be addressed with urgency. The financial impact of an FDA Form 483 Observation can be catastrophic, sometimes costing companies several million dollars. If the issues are systemic, the FDA Form 483 Observation can trigger training, redesign, process implementation, and other measures.

What is an FDA Warning Letter?

An FDA Warning Letter is an official deficiency letter from the agency, which is sent by the investigators of the agency. Companies may receive this document in the mail, without prior notification from FDA. Before a Warning Letter is issued, the FDA requests the company to comment on the deficiencies listed in the Form 483 Observations found during the inspection. If the FDA judges this response to be unacceptable, a Warning Letter will be issued.

Typically, FDA Warning Letters are sent to ensure overnight delivery and receipt of delivery (e.g., return receipt requested, FedEx). As with an FDA 483 Observation, the company has 15 days maximum to respond in writing. However, if the cause of the Warning Letter is severe, the FDA may shorten the deadline.

FDA Form 483 Observations and Warning Letters are sometimes mistakenly identified as the same thing. Like FDA Form 483 Observations, Warning Letters can be very costly and can significantly delay time to market and consume capital in the process. However, FDA Warning Letters are more serious than Form 483 Observations because they represent an escalation of the process. As such, agency feedback from an FDA Warning Letter should be addressed immediately.
