FDA Inspection Preparation Guide

What Types of FDA Inspections Are There?

FDA inspectors conduct inspections of facilities that manufacture, process, pack, or hold FDA-regulated products. These inspections verify compliance with applicable regulations and may be routine, for-cause (triggered by a complaint or problem), or pre-approval (before approving a new product).

How Do I Stay Inspection-Ready Year-Round?

The best inspection preparation is maintaining compliance every day. Facilities that are always inspection-ready have less stress and better outcomes when FDA arrives.

Continuous Compliance Practices

• Quality system maintenance: Keep quality systems current and functional, not just documentation
• Record-keeping: Maintain accurate, complete, and retrievable records at all times
• Training: Ensure employees are trained and training records are current
• CAPA system: Address issues promptly through corrective and preventive actions
• Internal audits: Conduct regular self-audits to identify and correct issues before FDA finds them
• Facility maintenance: Keep the facility clean and equipment properly maintained

Documentation Organization

Inspectors will request records and expect them to be provided promptly. Organize documentation for easy retrieval:

• Registration records: FDA registration confirmations, product listings
• SOPs: All standard operating procedures, current versions
• Training records: Employee training documentation and qualifications
• Batch records: Production and testing records for recent batches
• Complaint files: Consumer complaints and investigation records
• CAPA records: Corrective action documentation
• Validation records: Equipment, process, and cleaning validation

What Should I Do When FDA Inspectors Arrive?

When FDA investigators arrive at your facility, the first few minutes set the tone for the entire inspection. Having a clear protocol ensures a smooth start.

Initial Contact Protocol

1. Verify credentials: Ask to see the investigator's FDA credentials (Form FDA 200B). It's appropriate to examine them and record the investigator's name.
2. Review Notice of Inspection: FDA will present Form FDA 482 (Notice of Inspection). Review it to understand the scope of the inspection.
3. Contact your inspection team: Immediately notify designated personnel that FDA is on-site.
4. Provide appropriate space: Offer a conference room or work area for the inspectors to use.
5. Begin escort: Never allow inspectors to walk through your facility unescorted.

Your Rights During Inspection

While you must allow FDA access, you have certain rights:

• Right to have management present during the inspection
• Right to escort investigators throughout your facility
• Right to take notes and photos (if investigators do)
• Right to copies of any documents FDA copies
• Right to ask questions about the inspection
• Right to challenge unreasonable requests

What Happens During an FDA Inspection?

The inspection process typically involves facility tours, record review, employee interviews, and possibly sample collection. How you conduct yourself during this time significantly affects the outcome.

Best Practices

• Be cooperative: A cooperative attitude leads to better outcomes than an adversarial approach
• Be honest: Never lie or attempt to hide information. Investigators are experienced and will likely discover deception.
• Be precise: Answer questions accurately and completely, but don't volunteer information that wasn't asked
• Document everything: Keep detailed notes of questions asked, records reviewed, and observations made
• Correct minor issues immediately: If an inspector notes a small issue you can fix on the spot, do so
• Provide requested records promptly: Delays in providing records can create negative impressions

Handling Employee Interviews

FDA investigators may interview employees about their work. Prepare employees by:

• Training them on their job responsibilities and SOPs
• Advising them to answer truthfully and precisely
• Telling them it's okay to say "I don't know" if they don't know
• Informing them they can have a supervisor present
• Reminding them not to speculate or guess

Record and Sample Requests

Inspectors will request records and may collect samples. For records:

• Provide what is requested, but only what is requested
• Make copies of any documents FDA photocopies or takes
• Note which records were reviewed or copied

For samples:

• FDA has authority to collect samples
• Ask for a receipt (Form FDA 484) for all samples collected
• Collect duplicate samples if possible for your own testing

What Is an FDA Form 483 and How Do I Respond?

At the end of the inspection, the investigator will hold a closeout meeting and may issue Form FDA 483 (Inspectional Observations). This form lists observations of conditions that may constitute violations.

Receiving the 483

• Review carefully: Read each observation carefully during the closeout meeting
• Ask questions: Seek clarification on any observations you don't understand
• Request examples: Ask for specific examples or record references
• Don't argue: The closeout is not the time to dispute findings; focus on understanding them
• Sign the form: Signing acknowledges receipt, not agreement with the observations

Responding to FDA 483

A prompt, thorough response to the FDA 483 is critical. While not legally required, failure to respond may escalate to a Warning Letter.

Response Timeline

• 15 business days: FDA recommends responding within 15 business days
• Immediate corrections: Note any corrections made during the inspection
• CAPA plan: Include a corrective action plan with specific commitments

Response Content

For each observation, your response should include:

1. Acknowledgment of the observation (or respectful disagreement with explanation)
2. Root cause analysis
3. Immediate corrections taken
4. Long-term corrective actions planned
5. Preventive actions to prevent recurrence
6. Timeline for completion
7. Responsible parties

What Are the Possible FDA Inspection Outcomes?

FDA categorizes inspection outcomes based on findings:

What Should I Do After an FDA Inspection?

After the inspection, there's still work to do regardless of the outcome:

Immediate Actions

• Conduct a thorough debrief with the inspection team
• Review and organize all notes taken during inspection
• Begin drafting 483 response if applicable
• Start implementing immediate corrections

Follow-Up Activities

• Complete and submit 483 response
• Implement corrective and preventive actions
• Update SOPs as needed
• Conduct follow-up training
• Request the Establishment Inspection Report (EIR) via FOIA
