FDA inspections, 483s and Warning Letters are part of the FDA’s regulatory process to ensure that products created by manufacturers are safe for consumers. FDA inspections involve visiting a manufacturer’s facility to evaluate if they are in compliance with FDA regulations. The FDA may issue 483s if they find any non-compliances during their inspection. A 483 is a list of items that need to be corrected within 15 days or else further action will be taken by the FDA. If the FDA finds serious violations, such as failure to properly follow Good Manufacturing Practices (GMPs), they might issue a Warning Letter instead of a 483.
