FDA Warning Letter Response — Verus FDA

Rapid Triage, Corrective Actions & Submission-Ready Responses

We help companies respond to FDA warning letters with structured corrective action plans, documentation remediation, and defensible regulatory strategies that address root causes—not just surface-level compliance theater.

48-Hour Triage CAPA Development Documentation Remediation Response Drafting Reinspection Readiness

Why Warning Letters Require Immediate, Strategic Action

A warning letter isn't just a compliance issue—it's a public signal of serious regulatory concern. The 15-business-day response deadline is real, and inadequate responses trigger consent decrees, import alerts, injunctions, and loss of customer confidence.

Critical Timeline: FDA expects a comprehensive response within 15 business days of letter receipt. Partial responses or promises to "investigate further" typically fail.
  • Public disclosure: Warning letters are posted online—customers, partners, and competitors will see it.
  • Regulatory escalation: Inadequate responses lead to consent decrees, seizures, injunctions, or debarment proceedings.
  • Business impact: Major retailers, distributors, and contract partners may pause orders or terminate relationships.
  • Root cause requirement: FDA wants systemic fixes, not cosmetic corrections or vague commitments.

Warning Letter FAQs

How quickly can you start after we receive a warning letter?

We can typically begin triage within 24 hours of engagement. Our 48-hour emergency triage delivers a citation breakdown, risk assessment, and response roadmap so you can start corrective actions immediately.

What if we can't fix everything within 15 business days?

FDA understands that some corrective actions take time. The key is demonstrating that you've identified root causes, initiated meaningful corrective actions, and committed to specific timelines with interim milestones. We help structure responses that acknowledge complexity while showing serious commitment.

Can you work with our internal quality team or legal counsel?

Yes—we often collaborate with in-house quality, regulatory, and legal teams. We provide the regulatory strategy and technical documentation support while your team maintains final decision authority and attorney-client privilege where applicable.

What happens if FDA finds our response inadequate?

If FDA issues a follow-up letter indicating deficiencies in your response, we can provide additional corrective action development, enhanced documentation, and more detailed evidence to address their concerns. The goal is always to avoid escalation to consent decrees or other enforcement actions.

Are these pricing ranges fixed?

No—these are estimated ranges based on typical engagements. Every warning letter situation is unique, involving different numbers of citations, facility types, product categories, and quality system complexities. After reviewing your specific warning letter and understanding the full scope of required corrective actions, we provide a detailed flat-rate quote tailored to your situation. Complex, multi-site situations or consent decree work may exceed these ranges.
