When a drug or medical device turns out to be riskier than first thought, the FDA doesn’t keep quiet. It issues a safety communication - a public alert that tells doctors, pharmacists, and patients what’s changed. But what if you need to know what the FDA said about a drug five years ago? Or ten? Or back in 2012, before social media made alerts go viral? That’s where the FDA Safety Communications Archive comes in. It’s not just a list of past warnings. It’s a living record of how the U.S. government has tracked, reacted to, and tried to warn the public about medicine risks for over a century.
What’s in the FDA Safety Communications Archive?
The archive isn’t one single database. It’s three main systems working together, each with its own rules and time limits.Drug Safety Communications (DSCs) started in 2010 and are organized by year, from 2010 through 2024. These are the most common alerts you’ll find - things like "FDA warns against using this painkiller in patients with heart disease" or "New side effect found in diabetes drug." The FDA archives older DSCs not because they’re unimportant, but because they’ve been replaced. If a newer warning came out in 2023 that updated the 2015 alert, the 2015 version gets moved to the archive. That’s why you can’t always find the latest version by searching for an old alert - you have to check if it’s been superseded.
Drug Safety-related Labeling Changes (SrLC) Database is more technical. It tracks exact changes to the official drug label - the fine print doctors and pharmacists read. Since January 2016, every time the FDA requires a manufacturer to update a drug’s warning section - whether it’s a new boxed warning, a change in dosage for elderly patients, or a new drug interaction - it’s added here. The changes are pulled from sections like "Warnings and Precautions," "Adverse Reactions," and "Use in Specific Populations." This is the go-to source if you’re researching how a drug’s safety profile evolved over time.
Medical Device Safety Communications work differently. These alerts cover everything from faulty pacemakers to contaminated surgical tools. In September 2025, the FDA expanded its "Early Alerts" program to cover all medical devices, not just high-risk ones. These alerts are often the first public notice of a potential recall. Unlike drug alerts, they can include direct clinical recommendations - like "Stop using this device in pregnant patients" or "Replace this model immediately."
How to Find What You Need
If you’re looking for a specific warning, start at the FDA’s Drug Safety and Availability page. You can browse DSCs by year - just click on 2020, 2018, or 2014. Each entry includes the date, product name, type of risk, and a link to the full notice. For labeling changes, head to the SrLC Database. You can search by drug name, active ingredient, or even by the section of the label that changed.But here’s the catch: if you’re looking for information before 2016, the SrLC Database won’t help. That’s a gap. For drug labeling changes before 2016, you’ll need to dig into the FDA.gov Archive. This tool lets you see old versions of FDA web pages - like what the Drug Safety page looked like in 2013. It’s clunky, but it’s the only way to recover content that’s no longer on the live site.
For research going back even further - say, to the 1970s or 1900s - you’re entering archival territory. The National Archives in Philadelphia holds FDA records from 1877 to 1978. These include handwritten reports, letters from manufacturers, and early investigations into dangerous patent medicines. One famous example? Dr. Harvey Washington Wiley’s "Poison Squad" experiments in the early 1900s, where volunteers ate food laced with common additives to prove they were harmful. That work led directly to the 1906 Pure Food and Drug Act - the foundation of today’s safety system.
What the Archive Doesn’t Tell You
Just because the FDA issued a warning doesn’t mean doctors or patients changed their behavior. A 2012 study found that some alerts had immediate, strong effects - like a sharp drop in prescriptions after a black box warning. Others? Barely a ripple. Patients kept taking the drug. Doctors didn’t change their prescribing habits. Why? Because risk communication is hard. A warning buried in a 12-page PDF won’t reach someone who only sees their doctor once a year. A vague alert like "potential risk" doesn’t give clear guidance.Another limitation? The archive doesn’t explain why a change happened. It tells you the label now says "avoid in kidney patients," but it won’t say whether that came from a new study, a patient lawsuit, or a whistleblower report. That context is often missing.
And then there’s the device-drug divide. Drug alerts and device alerts live in separate systems. If you’re researching a combination product - say, a drug-coated stent - you have to check both archives. No single place pulls them together.
How This Archive Helps Real People
Let’s say you’re a researcher studying why a certain antidepressant suddenly had a spike in suicidal thoughts in teenagers. You find the 2004 DSC that first warned about this. Then you check the SrLC Database and see the label was updated in 2005 to include a boxed warning. You dig into the FDA Archive and find the 2003 internal memo where the agency debated whether to act. Now you have a timeline. You can see how the science, the regulation, and the public response unfolded over time.Or maybe you’re a pharmacist. A patient asks why their new prescription says "avoid with grapefruit juice" - but their old bottle didn’t. You pull up the SrLC Database, search the drug name, and find the 2021 update that added the interaction after a new clinical trial. You explain it to the patient with confidence.
Even patients can use it. If you’re considering a long-term medication and want to know its history - what went wrong before, how it’s been improved - the archive gives you the full story, not just the marketing brochure.
What’s New in 2025?
The FDA isn’t sitting still. In October 2023, it announced a new resource to help researchers collect historical data on drug approvals - a sign they’re trying to fill the pre-2016 gap. For devices, the expansion of Early Alerts to cover all products means more transparency, not less. And while the archive doesn’t yet combine drug and device data, the push for better search tools and clearer labeling is ongoing.The system isn’t perfect. But it’s the most detailed, publicly accessible record of post-market drug and device safety in the world. No other country keeps this level of historical detail. The European Medicines Agency’s alerts are harder to trace before 2015. Health Canada’s system is unified but less granular. The FDA’s separation of drug and device alerts, while confusing at first, allows for deeper, more precise tracking.
What you’re really accessing here isn’t just a list of warnings. It’s a century of public health decisions - made in real time, under pressure, with incomplete data. The archive doesn’t just tell you what went wrong. It shows you how the system learned to catch it next time.

For help finding something specific, contact the FDA’s Division of Drug Information at (855) 543-3784 or [email protected]. They can point you to the right archive, even if it’s buried in old files.
Can I find old FDA drug warnings from before 2010?
Yes, but not through the modern Drug Safety Communications archive, which only starts in 2010. For warnings before that, use the FDA.gov Archive to view older versions of FDA web pages. For records from the 1900s to 1978, the National Archives in Philadelphia holds physical and digitized documents, including early investigations into dangerous medicines and the original reports from Dr. Wiley’s "Poison Squad" experiments.
What’s the difference between a Drug Safety Communication and a labeling change?
A Drug Safety Communication (DSC) is a public alert - usually written for doctors and patients - explaining a newly identified risk, like a side effect or interaction. A labeling change, tracked in the SrLC Database, is the official, legally binding update to the drug’s package insert. DSCs can lead to labeling changes, but not all DSCs result in label updates. Labeling changes are more formal and legally enforceable.
Why can’t I find the latest version of an old FDA warning?
The FDA archives older Drug Safety Communications because they’ve been replaced by newer ones with updated information. If you search for a 2012 alert and can’t find it, look for a 2018 or 2022 version - it likely contains the current guidance. Always check if an alert has been superseded before relying on it.
Do FDA safety alerts always lead to changes in how drugs are used?
No. Research shows that some alerts cause immediate drops in prescriptions, while others have little to no effect. Why? It depends on how clear the message is, who receives it, and whether doctors and patients trust it. A vague warning like "potential risk" is less effective than a specific one like "do not use in patients with liver disease."
Is the FDA Safety Communications Archive free to use?
Yes. All Drug Safety Communications, the SrLC Database, and Medical Device Alerts are publicly accessible at no cost. You don’t need an account, subscription, or special access. The FDA also offers free help through their Division of Drug Information if you’re having trouble finding something.

November 6, 2025Man, I never realized how much history is buried in these FDA archives. Like, the Poison Squad? That’s wild. People actually ate poison just to prove it was dangerous? And now we got apps that tell us if our pills are safe. Crazy how far we’ve come - and how little most people know about it.

November 8, 2025This is the kind of stuff you wish your high school health class taught. Not just ‘don’t do drugs,’ but how the system actually works behind the scenes. The SrLC Database alone is a goldmine for anyone in med or pharma. I wish more patients knew about this.

November 8, 2025Oh please. The FDA’s ‘archive’ is just a PR stunt. Half these alerts are buried so deep you need a PhD in bureaucracy to find them. And don’t even get me started on how they ignore real crises until lawsuits pile up. This isn’t transparency - it’s damage control with a thesaurus.

November 8, 2025Let’s be real - the FDA’s system is archaic. You have to cross-reference three separate databases, dig through 1970s microfiche, and pray the URL hasn’t changed. Meanwhile, the EU has a unified portal and Canada’s system is intuitive. Why does America still operate like it’s 1998?

November 9, 2025Y’all act like this is some revolutionary thing. The FDA’s been doing this since the 1900s. Other countries? They’re still playing catch-up. You think Germany or Japan has better records? Nah. We built this system from scratch while they were still arguing over whether penicillin was a ‘miracle’ or ‘witchcraft.’

November 10, 2025THIS IS SO IMPORTANT!!! 🚨👏 I just looked up my antidepressant and found the 2004 alert… and now I’m crying. 😭 This is why we need more people to know this stuff. 🤍 #FDAarchive #patientpower

November 11, 2025fr tho why does the fda even have 3 diffrent sites for this? its a mess. i tried to find a warning from 2013 and ended up on a page about cat food recalls. 🤡

November 11, 2025Interesting breakdown. I’ve used the SrLC database for work before - it’s clunky but accurate. The real issue is that most doctors don’t check it. They rely on reps or Google. That’s why warnings don’t always stick. We need better integration with EHRs.

November 13, 2025...and yet, despite all this - the FDA still allows drugs like Zantac to stay on the market for *years* after known carcinogens are detected. This ‘archive’ is a monument to bureaucratic inertia. You call this ‘transparency’? It’s a graveyard of half-measures. And don’t even get me started on the device-drug divide… it’s a farce. 🤦♂️

November 14, 2025Thank you for this comprehensive overview. As a healthcare policy researcher, I can confirm: the FDA’s archive is indeed the most granular and historically rich public safety record of its kind globally. While the interface is outdated, the data integrity is unmatched. I routinely direct graduate students to the National Archives’ RG-88 collection for pre-1978 case studies - particularly the 1937 elixir sulfanilamide tragedy, which directly led to the 1938 Food, Drug, and Cosmetic Act. This is not just about warnings - it’s about the evolution of public trust in science. We owe it to future generations to preserve, digitize, and improve access to these records.
