FDA Warning Letter Lookup
When the FDA finds a serious problem, it sends the company a letter and publishes it. That letter is a dated, documented compliance event — this is how you find it by company.

The signal
What a fda warning letter tells you
An FDA warning letter is the agency's formal notice to a company that an inspection or review turned up violations serious enough to demand correction. The FDA publishes these letters, so a warning letter is a matter of official record — a specific, dated event, not a rumor or a rating.
This tool searches that published index by company name and shows you the product area, the issue date, and whether the letter has been closed out. It's the fast way to answer "has this firm been cited, when, and for what area of its business?"
The event that matters is the posting. A warning letter typically follows a Form 483 (the inspector's list of observations) and can precede stronger action if it isn't resolved. A close-out, when it comes, is the FDA's acknowledgment the firm addressed the issues. Both the letter and the close-out are moments worth catching when they happen.
Why it matters
A fresh warning letter reshapes a company's next two quarters — remediation spend, supplier scrutiny, and buyer risk reviews all move. Getting it the week it posts is the difference between reacting and being surprised.

FAQ
Frequently asked questions
What is an FDA warning letter?
It's the FDA's formal, published notice that a company has violations serious enough to require prompt correction. Because the FDA posts them, a warning letter is an official record and a specific dated event — this tool finds it by company name.
Is the FDA warning letter search free?
Yes. Search by company name with no login and see product area, issue date, and close-out status. A capped set of matches shows for free; the full index and fields like the alleged violation and issuing office are shown free — no email or login.
What's the difference between a Form 483 and a warning letter?
A Form 483 is the list of observations an FDA investigator leaves at the end of an inspection. A warning letter is the escalation that can follow if those observations aren't resolved — it's more formal and is published.
What does 'closed out' mean?
The FDA issues a close-out letter when it's satisfied the firm corrected the cited problems. If a letter isn't closed out, the compliance issue is still considered open on the record.
How often are new letters added?
The FDA posts new warning letters on a rolling basis, typically weekly. ParseData reads the same index, so newly posted letters appear shortly after publication.
How it's sourced
Reads the FDA's published Warning Letters index — letters the agency itself posts. Observational: we show what the letter states and its status, never a judgment about the company.
