You must draft FDA Form 483 response within 15 days and state how you plan to address the FDA’s finding. It is necessary to provide a thorough explanation for each observation or breach detected. Your answer to this letter, both in terms of quality and timeliness, is crucial.

Act Immediately

Even if you think something might be incorrect, your response should be specific enough to demonstrate why you disagree with the observation.

Give solid evidence to support any assertions

Every assertion and reaction you make in your response must be supported by verifiable data.

The FDA has no use for assertions that are not supported or poorly stated since they only serve to cast further doubt on your ability to address the issues raised.

You can opt to engage the expertise of outside experts to undertake an impartial evaluation of the quality and appropriateness of the response prior to submission to assure effectiveness and objectivity.
