How do you prepare a response to an FDA promotional letter or information request?
Work from the actual communication and tracking reference. Account for each issue or question, state verified facts, identify supporting records and distinguish completed actions from plans. Include applicable requested or corrective materials and assess similarly affected pieces. Match the response category and deadline to the actual letter; a warning-letter template is not a substitute for answering a specific information request.
Before you begin
Responses concerning promotion. An untitled/warning letter and an information request are different triggers; use the actual letter, responsible FDA office and response instructions.
What you will prepare: A point-by-point response and evidence manifest reviewed by the responsible regulatory, legal and business owners.
Sections covered in this guide (2)
Work from the exact agency communication
Capture the date, product, tracking reference, issues and response instructions. For an information request, answer the questions and provide the requested materials. For an untitled or warning letter, address the identified concerns and applicable corrective material. Do not relabel one type as another to change the perceived seriousness or expected response.
Build a fact-and-action response matrix
| Agency item | Verified fact or position | Supporting record | Action and status | Owner |
|---|---|---|---|---|
| Defined claim/presentation | What was used, where and when | Actual piece and distribution record | Completed action or proposed next step | Responsible function |
Separate what the company knows from what it is still investigating. Identify materially similar pieces and affected channels; an isolated correction may leave the same issue elsewhere. Give evidence for completed actions and a truthful plan for unfinished ones. Do not invent a cessation date, distribution count or legal concession.
Make corrective material and follow-up traceable
Sections IV.H–I and VI.E provide preparation context. Identify whether the response is initial or follow-up, link it to the original communication, and label corrective pieces clearly if included. Preserve the original material for the record. Ensure attachment versions and statements in the response agree; “removed everywhere” is unsupported if channel checks are incomplete. Resolve the response deadline from the letter and applicable instructions rather than a generic template.
Fictional example: planned action described as complete
The draft says a website claim has been removed, but deployment is only scheduled. Correct the status to the verified facts and have the owners approve the plan. After execution, capture the evidence for a follow-up. If FDA asks a narrow factual question rather than alleging a violation, answer it precisely without importing unrelated admissions from a warning-letter template.
Define what evidence would close each response item
Build the response from the agency's numbered issues or questions, keeping the original wording and your proposed answer distinguishable. An internal status of “done” is meaningful only if the underlying action can be verified.
| Response component | Evidence to assemble | Unresolved condition to preserve |
|---|---|---|
| Agency item | Exact question or concern and letter date | Scope or meaning needs clarification |
| Material and use | Actual version, channel, audience and distribution record | Dates, reach or archived variants not yet established |
| Position or answer | Verified facts and reviewed explanation | Investigation or scientific assessment incomplete |
| Corrective action | Specific action, accountable owner and timing | Planned action must not be described as completed |
| Completion evidence | Actual revised/removed material and channel check | One channel verified while others remain unchecked |
| Related materials | Search scope, matching pieces and 2253 submission dates where applicable | Similar claims or presentations remain unevaluated |
| Follow-up | Open item, next evidence and communication plan | A commitment cannot yet be supported |
Guidance VI.E describes a list of promotional materials containing similar violations, with their 2253 submission dates, for an initial response to an untitled or warning letter. Use the actual issue to define the search: exact wording, meaning, imagery, product and audience may all matter. Searching only for one identical headline can miss the same presentation in a video, translated piece or downloadable brochure.
Fictional completeness exercise: the response says an identified claim was removed from the website. The main page has changed, but a linked PDF and a partner-hosted version still contain it. Preserve the narrow verified statement and identify the remaining work. After action, check the affected destinations and record the evidence. Do not state that all material was removed because the source design file was edited.
Keep source material and corrective versions identifiable in the record. For each attachment, explain its role and confirm that the response cites the right version. An initial answer may need a later update; label the relationship rather than presenting the follow-up as a new unrelated submission. If information is unavailable, explain the specific gap and the reviewed plan instead of supplying a plausible number or invented completion date.
The actual letter and applicable instructions control the response timing and requested actions. A generic template cannot determine the firm's factual or legal position. Obtain the relevant regulatory, legal, medical and operational review for those decisions. Use the evidence-package guide for corrective artifacts and the submission-planning guide to keep an information-request response distinct from general correspondence or a warning-letter response.

Frequently asked questions
Can a planned corrective action be described as completed in the FDA response?
No. State the verified status and distinguish the planned action, responsible owner and timing from completed work. Obtain evidence after execution and communicate follow-up as appropriate. A scheduled deployment, approved artwork change or internal ticket closure does not itself establish that the disseminated material changed.
Should the review cover only the piece named in the agency letter?
Assess the actual letter and related materials. Guidance VI.E describes listing materials with similar violations and their 2253 submission dates in an initial untitled- or warning-letter response. Define and document a meaningful search across relevant channels and presentations instead of assuming the named piece is the entire scope.
Is an information-request response the same as a warning-letter response?
No. Guidance IV.H and IV.I identify different correspondence types. Answer the actual questions or concerns, provide requested material and retain the agency tracking reference. Do not import unsupported admissions or a corrective-action narrative from a warning-letter template into a narrower inquiry without establishing its relevance.
Where should the response deadline come from?
Read the actual agency communication and applicable instructions, then confirm any unresolved timing with the responsible regulatory and legal owners. This preparation guide does not supply one universal deadline. Record the basis for the date and track outstanding evidence early enough to support a truthful response.
