How to Search FDA’s Drugs@FDA Database for Official Drug Information

Knowing when a drug was approved, what’s in it, or whether a brand name has a generic version can matter a lot-whether you’re a patient, a pharmacist, or a caregiver. The Drugs@FDA database is the U.S. Food and Drug Administration’s official public tool for finding this kind of information. It’s not a marketing site. It’s not a drug review blog. It’s the raw, regulatory record of every human drug approved in the U.S. since 1939. And it’s free, open, and updated every single day.

What You’ll Find in Drugs@FDA

Drugs@FDA doesn’t just list drug names. It gives you access to the full regulatory file for each approved product. For drugs approved since 1998, you’ll see:

• The official prescribing information (the full drug label)
• Patient medication guides
• Approval letters from the FDA
• Review summaries from FDA medical and pharmacology experts
• Correspondence between the drug company and the FDA

Even for older drugs-those approved before 1998-you’ll still get the approval date, the active ingredient, and the application number. That’s enough to track down whether a drug is still on the market or if its approval was withdrawn.

It covers everything from common pills like metformin to complex biologics like Humira. It includes brand names, generics, combination drugs, and even some discontinued products. The database holds records for about 20,000 approved human drugs. And unlike other FDA tools, it goes back decades. That’s rare. Most databases only show recent data.

How to Search: Three Ways to Find What You Need

You don’t need to be a scientist to use Drugs@FDA. But you do need to know which search method works for what you’re looking for. There are three main ways to search:

1. Use the Homepage Search Box

This is the easiest and most powerful way. Go to fda.gov/drugsatfda and type into the big search box at the top.

You can search by:

• Brand name (like Zoloft, Lipitor, or Humira)
• Generic name (like sertraline, atorvastatin, or adalimumab)
• Active ingredient (even if it’s part of a combo drug)
• Application number (NDA, ANDA, or BLA-this is for advanced users)

Try searching for “lisinopril.” You’ll see all products containing it: Zestril, Prinivil, Qbrelis, and even combo pills like Zestoretic. The search box finds them all. That’s the advantage over the A-Z index.

2. Use the A-Z Index (Use With Caution)

The A-Z index looks simple: click a letter, scroll through drug names. But it’s misleading.

Searching for “LISINOPRIL” in the A-Z index will only return products where “lisinopril” is listed as the primary name. It won’t show you Zestril or Qbrelis. It won’t show you Zestoretic. That’s because the A-Z index is built on a different system-it’s meant for browsing, not searching.

Use the A-Z index if you’re just exploring. Don’t use it if you’re trying to find every product with a certain ingredient. The homepage search box is always better.

3. Search by Application Number

If you know the NDA, ANDA, or BLA number (for example, NDA 020472), you can paste it directly into the search box. This is how regulatory professionals, pharmacists, and researchers find exact records quickly. Application numbers are usually printed on the FDA’s approval letters or in official documents.

You can find these numbers in the “Application Number” field on any Drugs@FDA result page. Save them if you’re doing repeated research.

What Drugs@FDA Doesn’t Show

It’s important to know what this database doesn’t cover-so you don’t waste time looking for something that isn’t there.

• Animal drugs - Those are in a separate database called Animal Drugs@FDA.
• Detailed patent info - Drugs@FDA lists patent numbers, but not expiration dates or legal disputes. For that, use the Electronic Orange Book.
• Section-by-section label searches - Want to find all drugs with a boxed warning about liver damage? Drugs@FDA won’t let you do that. Use FDALabel instead.
• Biologics only - The Purple Book is the go-to for biologics like vaccines and monoclonal antibodies. Drugs@FDA includes them, but the Purple Book gives more detail.

Think of Drugs@FDA as your first stop. It tells you: Is this drug approved? When? Who made it? What’s in it? Then, if you need more-like patent dates or specific warnings-you move to another tool.

Real-World Uses

People use Drugs@FDA every day for real reasons:

• A pharmacist checks if a new generic version of a drug was approved before filling a prescription.
• A patient looks up their medication to confirm it’s not a recalled product.
• A researcher compiling data on diabetes drugs uses it to verify approval dates for a study.
• A healthcare provider answers a patient’s question: “Was this drug approved before 2010?” in seconds.

One pharmacist told the FDA: “I used to call the agency just to ask when a drug was approved. Now I just check Drugs@FDA. It saves me 15 minutes every time.”

Pro Tips for Better Results

• Try both brand and generic names. If you search for “Lipitor,” you’ll find it. But if you search for “atorvastatin,” you’ll find all the generics too.
• Use quotes for exact phrases. Searching for “Zestril and hydrochlorothiazide” will give you better results than just typing the words.
• Check the approval date. A drug approved in 1999 might have different labeling than one approved in 2020.
• Download the label. Click “View Label” to get the full prescribing info as a PDF. Keep it for reference.
• Bookmark the results. The URL changes with your search, so save it if you’ll need it again.

How It Compares to Other FDA Tools

Drugs@FDA isn’t the only FDA drug database. Here’s how it stacks up:

Most users start with Drugs@FDA. If they need more, they move to one of the others. It’s like using Google Maps to find a city, then switching to a detailed street map once you’re there.

Common Mistakes to Avoid

• Using the A-Z index for detailed searches. It’s outdated for this purpose.
• Assuming all brand names are listed. Some older brands were discontinued and don’t appear unless you search by ingredient.
• Not checking the approval date. A drug approved in 2005 might have different dosing than one approved in 2023.
• Forgetting combination products. If you’re looking for a drug like “Zestoretic,” you need to search for both ingredients: “lisinopril and hydrochlorothiazide.”

Final Thoughts

Drugs@FDA is one of the most underused public health tools out there. It’s not flashy. It doesn’t have animations or user reviews. But it’s accurate, official, and free. If you’re ever in doubt about a drug’s approval status, history, or contents-go here first. It’s the closest thing to the FDA’s internal records that the public can access.

And if you’re still unsure? The FDA has videos and guides on their website. No registration. No cost. Just clear instructions.
