FDA 483s Resource Center

Form FDA 483s.  If you’re part of the very small community of people who have “FDA 483s” in your vocabulary, we’ve created this web resource for you.  Please see our list below of most helpful resources about FDA 483s.

Let’s start with why 483s matter: A Bad 483 Can Cost a Company Millions.  We’ve heard too many stories of how one 483 was only the tip of the iceberg. This is why understanding the root issues inside 483s deserve your attention. You don’t want your CEO ever to say the words “FDA 483” or “manufacturing quality issues” on the national news.


Introduction to FDA 483s

  1. New to FDA 483s? Start here: FDA 483s (Wikipedia), the best 101 (and beyond) for understanding Form FDA 483s.
  2. FDA website ORA Reading Room.  The FDA makes available Form FDA 483s that are “frequently requested” at this reading room.  Though these Form FDA 483s only make up a small percentage of all their Form FDA 483s, it is helpful to check this page for updates (updated 1-2 times/month). We’ve noticed recently (as of late 2018) the FDA has increased their publishing rate and made more FDA 483s available, which is great for our industry.
  3. What’s the big deal about these Form FDA 483? Another great introductory post if you are new to the industry – “483s” is shorthand for “Form FDA 483s,” the official inspection report that documents FDA inspector observations of manufacturing facilities.  A response from the inspected company is not required, but strongly encouraged.
  4. Who can see FDA 483s, and where do I get them? Anyone can request 483s from the FDA through the Freedom of Information Act.  But it can take anywhere from a few days to a few weeks (and occasionally, much longer than that) to receive the document.  Keep in mind that your request is in itself public information, so people can find out what you’re poking around for.  This is why we created the 483s store, for searchable, instantaneous, and anonymous access to thousands of 483s.
  5. The Various Types of FDA Inspections.  While being ready looks the same no matter what type of inspection occurs, it’s still helpful to understand what the FDA is specifically looking for.
  6. A while back, we asked for the list of all 483-related Freedom of Information Act requests made to the FDA – this 483s FOIA Info PDF is the result.  In 1 year, the FDA processed roughly 1,300+ 483-related FOIA requests. As you go through the list, you’ll see that it’s not just industry professionals who are analyzing these reports – you’ll also find investment firms, law firms, consulting firms, and even the media.  


Let’s Get More Technical – Going Deeper with FDA 483s

  1. How to Respond to a Form FDA 483 (Redica Systems Blog).  This is a complicated question and has many complicated answers.  But the short answer is as specifically, comprehensively, quickly, and logically as possible for every single observation.  Attack each one with passion.  Explain to the FDA how the observations will be addressed, when, and how you’ll monitor it on an on-going basis.  Don’t be that company that gets repeat violations.
  2. How to Prepare for a GMP Inspection (at Smaller Companies).  This is a great resource for small companies and for any team that is resource-constrained.
  3. 5 Features to Look for in an EIR.  And, finally, you should look for specific aspects in a document called the Establish Inspection Reports (EIR) which the inspector uses to document every step of the inspection process. Not everyone agrees that these documents are worth the time, but many colleagues we have talked with like to read through the “play-by-play” of a particular inspection, giving them a more nuanced view of the inspector’s mentality and areas of focus.
