You might have a prescription for a brand-name medication that costs hundreds of dollars a month. You know generics exist and are cheaper, but sometimes the pharmacy says the generic isn't available yet. Then, they offer you an "authorized generic" at a lower price than the brand, but higher than a standard generic. It’s confusing. Is it safe? Where does it come from? And how can you verify if one exists for your specific medication?
Finding this information is harder than it should be because authorized generics don’t show up in the usual places. They aren’t listed in the famous FDA Orange Book where most generic drugs live. Instead, they sit on a separate, less-known list maintained by the U.S. Food and Drug Administration (FDA). This guide will walk you through exactly where to find that list, how to read it, and why there is a difference between these products and the generics you usually see.
What Exactly Is an Authorized Generic?
To understand where to look, you first need to know what you are looking for. An authorized generic is the exact same drug as the brand-name version, manufactured by the same company, but sold under a different label without the brand name.
Think of it like this: A major pharmaceutical company makes a popular heart medication called "BrandX." When the patent for BrandX expires, other companies can make their own versions (traditional generics). But before those competitors launch, the original maker of BrandX might decide to sell the identical pill under a plain white box labeled just with the chemical name, say "Atorvastatin," instead of "BrandX." That is an authorized generic.
The key difference lies in the paperwork. Traditional generics get approved through an Abbreviated New Drug Application (ANDA) and must prove they are bioequivalent to the brand. Authorized generics are marketed under the brand manufacturer's original New Drug Application (NDA). Because they are literally the same product coming from the same factory line, they are considered therapeutically equivalent by definition. However, they do not go through the ANDA process, which means they are excluded from the FDA’s primary database for generic drugs, known as the Orange Book.
Where to Find the Official FDA List
If you want to check if an authorized generic exists for a specific drug, you cannot rely on Google searches or general pharmacy websites. You need the source data. The FDA maintains a specific document titled the "Listing of Authorized Generic Drugs."
Here is how to access it:
- Go to the FDA’s official website.
- Navigate to the section on drug approvals and databases. Specifically, look for the page dedicated to abbreviated new drug applications (ANDAs), even though authorized generics use NDAs. The link typically resides under
fda.gov/drugs/abbreviated-new-drug-application-anda/fda-list-authorized-generic-drugs. - On this page, you will find a direct download link to a PDF file containing the current list.
As of the latest updates in late 2025, this list is published as a static PDF document. It is updated quarterly, as mandated by the Medicare Prescription Drug, Improvement, and Modernization Act of 2003. The most recent version available often dates back several months, so keep in mind that the data reflects reports submitted annually by manufacturers, not real-time market changes.
How to Read the Authorized Generics List
Once you download the PDF, you might feel overwhelmed. It looks like a dense spreadsheet. Don’t worry; it follows a consistent structure. Each entry contains four critical pieces of information:
- Proprietary Name: This is the brand name of the drug (e.g., ACTIQ, ARTHROTEC).
- Dosage Form and Strength: Details like "Lozenge 1200 mcg" or "Tablet 50 mg/200 mcg."
- NDA Applicant Name: The company that holds the rights to the brand name and manufactures the authorized generic (e.g., Cephalon, LLC, Pfizer Inc.).
- Date Entered Market: The period when the drug was first reported as an authorized generic.
For example, if you search for "ARTHROTEC," you might find an entry showing it was entered into the market on November 1, 2012, by Pfizer Inc. This tells you that Pfizer sells a non-branded version of Arthrotec. However, there is a catch with the date column. The FDA explicitly states that this date reflects the annual reporting period, not necessarily the exact day the drug hit the shelves. Furthermore, the list does not track whether the drug is still being sold today. A drug might appear on the list from 2015, but the company may have stopped producing the authorized generic version last year.

Why Can’t You Just Check the Orange Book?
This is the most common mistake people make. The FDA Orange Book (Approved Drug Products With Therapeutic Equivalence Evaluations) is the gold standard for checking generic availability. If you type a drug name into the Orange Book, you see a list of generic manufacturers and their therapeutic equivalence codes (like AB, AA, etc.).
However, authorized generics are invisible here. Because they are sold under the brand manufacturer’s NDA, they are legally part of the brand product’s record, not a separate generic application. The Orange Book only lists drugs approved via ANDAs. So, if you are looking for an authorized generic of a popular statin or painkiller, the Orange Book will tell you nothing about it. You must cross-reference the Orange Book (to see traditional generics) with the FDA’s separate Authorized Generics List (to see if the brand maker is also selling a plain-label version).
Limitations of the Official List
While the FDA list is the only authoritative public source for identifying which drugs have authorized generic versions, it has significant blind spots for everyday users.
1. No Real-Time Availability
The FDA admits it does not know if an authorized generic is still on the market. The list is built from annual reports submitted by companies. If a company stops selling the authorized generic version in January but doesn’t update their report until next year, the drug remains on the list. Pharmacists and researchers often find entries that are technically correct historically but practically useless because the product is discontinued.
2. Lack of Pricing Data
The list tells you *that* an authorized generic exists, but not *how much* it costs. Prices fluctuate based on supply, demand, and competition from traditional generics. To get pricing, you would need to check with wholesalers or use commercial databases like IQVIA, which track sales perspectives.
3. Searchability Issues
Currently, the list is a PDF. You cannot filter by therapeutic class, expiration date, or manufacturer easily. You have to manually scan or use the "Find" function in your PDF reader. The FDA has announced plans to transition this to a dynamic, searchable database format by mid-2026, which should improve usability significantly.
Practical Steps for Patients and Pharmacists
If you are a patient trying to save money, or a pharmacist looking for alternatives, here is a workflow that works better than relying solely on the FDA PDF:
- Check the Orange Book First: See if any traditional generics are approved. If yes, those are usually the cheapest option.
- Consult the FDA Authorized Generics List: Download the latest PDF and search for your drug’s brand name. If it appears, note the manufacturer.
- Verify with Your Pharmacist: Ask specifically, "Is the brand manufacturer currently selling an authorized generic version of this drug?" Pharmacists have access to wholesaler inventories (like McKesson or AmerisourceBergen) that show real-time stock, which the FDA list lacks.
- Use the NDC Directory: If you find a National Drug Code (NDC) associated with the authorized generic, you can look it up in the FDA’s National Drug Code Directory to confirm its labeling status.
Industry experts, including analysts from the Federal Trade Commission (FTC), note that authorized generics are often used strategically by brand companies to protect market share during the 180-day exclusivity period granted to the first generic applicant. Understanding this context helps explain why these products exist-they are a middle ground between high-cost brands and low-cost generics.
Future Changes to Watch
The landscape for finding this information is shifting. In 2024, stakeholders at an FDA public meeting requested better search functionality and real-time updates. The FDA’s Center for Drug Evaluation and Research (CDER) has acknowledged these needs. By Q2 2026, we expect the static PDF to be replaced by an interactive web tool. This will likely integrate with the Drug Shortage Portal, providing clearer visibility on whether an authorized generic is actually available or if it is merely a historical artifact.
Until then, treat the FDA’s PDF list as a starting point for research, not a definitive inventory. Combine it with professional pharmacy resources to ensure you are getting accurate, actionable information for your health decisions.
Is an authorized generic the same quality as the brand name drug?
Yes. An authorized generic is manufactured by the same company using the same facility and processes as the brand-name drug. It contains the same active ingredient, strength, dosage form, and route of administration. The only differences are the packaging and the label, which omits the brand name.
Why aren't authorized generics listed in the FDA Orange Book?
The Orange Book tracks drugs approved through Abbreviated New Drug Applications (ANDAs). Authorized generics are marketed under the brand manufacturer's original New Drug Application (NDA). Since they do not undergo the ANDA approval process, they are excluded from the Orange Book and tracked separately in the FDA's Listing of Authorized Generic Drugs.
How often is the FDA list of authorized generics updated?
The FDA is required by law to update the list quarterly. However, the data within the list comes from annual reports submitted by manufacturers, so it may lag behind real-time market conditions. The most recent updates reflect data submitted in the previous reporting periods.
Can I find the price of an authorized generic on the FDA website?
No. The FDA list provides information on the existence, manufacturer, and market entry date of authorized generics, but it does not include pricing information. Prices vary by pharmacy, region, and insurance coverage. You must consult your pharmacist or wholesaler for current costs.
Are authorized generics always cheaper than brand names?
Typically, yes. Authorized generics are priced lower than the brand-name version to compete with traditional generics. However, they are usually more expensive than traditional generics. The savings depend on the specific drug, the level of competition, and your insurance plan's formulary.
Does the FDA list show if an authorized generic is currently available?
No. The FDA explicitly states that the list does not indicate whether an authorized generic is still being marketed. It serves as a historical record of drugs that have been launched as authorized generics. To determine current availability, you should check with your pharmacist or use commercial drug distribution databases.
