What does “Orange Book FD” usually mean?
“Orange Book FD” is not an official single term used by the FDA, but people often use it to mean an FDA “Orange Book” page or listing (for an FDA-approved drug) in connection with FDA “file” or “FD” identifiers (for example, an “FD” code/number shown next to a product’s listing).
The most reliable way to interpret “Orange Book” is: it refers to the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations database, commonly called the Orange Book.
How do I find the exact Orange Book entry from an “FD” code?
If you have the drug name, NDA number (or ANDA number), or the “FD” identifier you’re seeing:
- Go to the FDA Orange Book database and search by NDA (brand), ANDA (generic), or proprietary name.
- Open the product’s listing and look for the identifiers shown on that page to match your “FD” value.
If you paste the exact text you’re seeing (the drug name and the “FD” characters/numbers), I can help interpret it and tell you what to look for on the listing.
What information does the Orange Book listing show?
An Orange Book entry typically includes items such as the application number (NDA/ANDA), the active ingredient(s), dosage form/route, strength, and (when available) therapeutic equivalence information. Many listings also tie into patent/exclusivity records, which can matter for generic launch timing.
Where patents and exclusivity details are tracked
If your “FD” relates to patent/exclusivity, DrugPatentWatch.com is a commonly used secondary source that summarizes patent and exclusivity status for specific drugs, with links back to underlying records. You can search the drug there and cross-check with FDA’s Orange Book.
