Food and Drug Administration (FDA)

The U.S. Food and Drug Administration's original purpose was to regulate the selling of misbranded food and drugs. Over the years, the agency’s role grew to include the approval and regulation of medical devices in addition to pharmaceuticals. It also supervises drug, device and vaccine recalls. The agency collects reports of adverse events and warns the public when needed.

Jump To Content

    The U.S. Food and Drug Administration (FDA) is the government agency responsible for reviewing, approving and regulating medical products, including pharmaceutical drugs and medical devices. It also regulates various other products, including food, cosmetics, veterinary drugs, radiation-emitting products, biological products and tobacco.

    The agency's origins began with the passage of the 1906 Pure Food and Drugs Act, a law created to curb manufacturer abuses in the consumer product marketplace. It was officially named the Food and Drug Administration in 1930.

    Fda Logo and departments
    Americans receive as many as 3 billion prescriptions for pharmaceuticals each year, and millions receive medical devices such as hip and knee implants. All medications and medical devices come with inherent risks, but it is the FDA’s duty to address serious risks that can be avoided and managed.

    The FDA’s regulation responsibilities include working with manufacturers to recall problematic products and collecting reports on adverse events—injuries or side effects caused by drugs, devices and vaccines. Manufacturers, doctors and patients may report adverse events to the FDA. If the agency decides these reports are serious, it may issue a safety communication to the public.

    But even with a system in place to ensure a new or existing product’s safety and minimize its risks, unexpected complications can arise.

    Critics and consumer watchdog groups accuse the FDA of being too influenced by Big Pharma and say the agency approves drugs too quickly. They also say the current FDA method for clearing medical devices for sale, the 510(k) premarket approval process, allows untested devices to harm consumers.

    As a result, the public's approval of the FDA has steadily declined. In 2015, only about half of Americans thought the FDA was doing a good job of protecting the public.

    FDA Organization and Regulation

    The FDA is an agency within the U.S. Department of Health and Human Services. Because it regulates a wide variety of products, it is broken down into five different offices: Office of the Commissioner, Office of Foods and Veterinary Medicine, Office of Global Regulatory Operations and Policy, Office of Medical Products and Tobacco and Office of Operations.

    In addition to the 50 states, the FDA's responsibilities extend to the District of Columbia, Puerto Rico, Guam, the Virgin Islands, American Samoa, and other U.S. territories and possessions.


    The FDA's regulatory responsibilities are:

    • Ensuring the safety and proper labeling of food
    • Ensuring the safety and effectiveness of human and veterinary drugs, medical devices, vaccines and biological products
    • Protecting the public from radiation from electronics

    FDA Sectors

    Office of Medical Products and Tobacco

    While the FDA oversees a number of products, it gets the most scrutiny for its regulation of prescription drugs and medical devices. This responsibility falls to the Office of Medical Products and Tobacco. The Office of Medical Products and Tobacco is made up of six centers.

    FDA Cber Office

    Center for Biologics Evaluation and Research (CBER)

    Center for Biologics Evaluation and Research (CBER) regulates biologics such as blood products, tissue products and vaccines.

    FDA Radiology Office

    Center for Devices and Radiological Health (CDRH)

    Center for Devices and Radiological Health (CDRH) regulates medical devices such as knee and hip implants and radiation-emitting products such as MRIs and X-ray machines.

    FDA Oncology Office

    Oncology Center of Excellence

    Oncology Center of Excellence works specifically with drugs, devices and biologics for the treatment of cancer.

    FDA Tabacco Office

    Center for Tobacco Products (CTP)

    Center for Tobacco Products (CTP) reviews premarket applications for tobacco products, oversees the implementation of warning labels and enforces restrictions on promotion and advertising.

    FDA Medical Office

    Office of Special Medical Programs

    Office of Special Medical Programs works with all FDA departments for special programs and initiatives that are clinical, scientific or regulatory in nature. It also leads the Advisory Committee Oversight and Management Staff.

    Drug Evaluation Office

    Center for Drug Evaluation and Research (CDER)

    Center for Drug Evaluation and Research (CDER) regulates prescription and over-the-counter drugs. Generic drugs and biological therapies are also included in this group. In addition to these, the center also oversees consumer products with ingredients considered a drug such as dandruff shampoo, antiperspirants and fluoride toothpastes.

    How the FDA Regulates and Approves Drugs

    CDER is the largest of the FDA's six centers and deals with all prescription and over-the-counter drugs. When drug companies need new drug approval, they submit their applications to CDER. The center does not conduct its own tests on drugs. Instead it relies on data and research provided by drug manufacturers.

    This center works with drug companies throughout the drug-approval process from the application to the final drug approval. A team of CDER scientists, physicians, statisticians, chemists and pharmacologists review the data and suggest labeling for pharmaceutical products.

    FDA Steps

    Steps to FDA Drug Approval:

    • Drug company develops drug and conducts animal testing
    • Drug company sends an investigational new drug application (IND) to the FDA with a plan for human clinical trials
    • Drug manufacturer conducts Phase I, II, and III clinical trials on humans
    • Drug company fills out a formal new drug application (NDA) for marketing approval
    • FDA reviews clinical trial data for drug safety and effectiveness
    • FDA reviews proposed drugs label and inspects manufacturing facilities
    • FDA will either approve or deny the drug

    Fast Track Programs

    The FDA approves more drugs faster than its counterparts in Europe and other countries. In order to keep up with the demand for new treatments, Congress passed the Prescription Drug User Fee Act (PDUFA) in 1992. This law allowed drugs that meet needs for serious or life-threatening conditions to be approved more quickly. Under the PDUFA, the FDA created a number of fast-track programs to facilitate faster approval.

     FDA Fast Track

    Fast-Track Designation

    Allows priority review of drugs for unmet medical needs and serious conditions.

    FDA Accelerated approval

    Accelerated Approval

    Allows drug to be approved with "surrogate endpoints." For example, surrogate endpoint data may show a cancer drug can shrink a tumor but not that it can extend a patient's life.

    FDA breakthrough designation

    Breakthrough Therapy Designation

    Manufacturers must prove their drug is safer or more effective than treatments already on the market.

    FDA priority review designation

    Priority Review Designation

    This is for drugs that are very effective at treating, diagnosing or preventing a condition. Priority review drugs may also work better with fewer side effects than drugs already on the market and treat a new population, such as children or the elderly.

    Online Pharmacies and Fake Medications

    CDER launched a campaign to promote awareness about online pharmacies. Because the FDA does not regulate these products, there is no guarantee of safety. The FDA warns that these drugs may be contaminated, counterfeit, expired or have other quality issues.

    These pharmacies may also collect personal and financial information, run internet scams or infect computers with viruses.

    In October 2012, the CDER worked with more than 100 other countries to shut down more than 18,000 illegal pharmacy websites.

    Operation Pangea V
    The global effort, called Operation Pangea V, took place Sept. 25 through Oct. 2. By the end of the week, regulatory agencies seized 3.7 million doses of fake medicines worth $10.5 million and 79 people were arrested, Reuters reported.

    Interpol, the World Customs Organization, the Permanent Forum of International Pharmaceutical Crime, the Heads of Medicines Agencies Working Group of Enforcement Officers, Pharmaceutical Security Institute and Europol directed Operation Pangea V.

    The FDA took action against 4,100 websites. Three main companies — CanadaDrugs.com, Eyal Bar Oz and Arkadiy Kisin/White Forest Solutions — were linked to most of the 4,100 illegal pharmacies, according to Bloomberg Businessweek.

    They received warning letters from the FDA, stating that their websites were offering unapproved drugs to U.S. consumers. The agency gave the companies 10 days to respond to the allegations. The FDA also notified internet service providers that the websites were selling illegal products.

    Viagra and Tamiflu Pills

    The most common drugs for sale on these websites included:

    • Viagra, Levitra and Cialis, erectile dysfunction drugs 
    • Norplant, a contraceptive
    • Unapproved generic version of influenza treatment Tamiflu
    • Unapproved antibiotic Baycip TZ
    • Stomach disorder drugs

    Medical Device Regulation and Approval

    The Center for Devices and Radiological Health (CDRH), another branch of the FDA, approves all medical devices sold in the United States. It also oversees how the devices are manufactured and monitors their safety. Depending on the classification of the device — Class I, II, or III — the manufacturer will apply for FDA clearance through two general methods: the 510(k) premarket notification or the premarket approval (PMA).

    Class I devices are low risk devices such as dental floss. Class II devices are higher risk and require more regulatory controls.

    Operating table illustration

    510(k) Premarket Notification

    Unlike drugs, most medical devices do not go through the same rigorous clinical trial process. Instead, they go through a process called the 510(k) premarket notification process.

    Device companies can submit an application with basic info comparing their Class I or II device, such as a hip or knee implant, with one already on the market. If it is "substantially equivalent" and the device company pays a user fee of about $4,600, the FDA will clear the device for sale.

    Premarket Approval (PMA)

    The FDA classifies life-sustaining devices as Class III. These devices cannot go through the 510(k). Instead they apply for premarket approval (PMA) with more rigorous testing and higher user fees. According to the FDA, this is a very rigorous review process. Examples of Class III devices are defibrillators or pacemakers.

    Former FDA project manager Madris Tomes explains the FDA's premarket approval process

    How FDA Conducts Recalls

    Contrary to what most people believe, the FDA can only compel a recall of a product made of human cells or tissues. Vaccines and blood products fall into this category.

    But the agency can only request a recall for a drug. Most of the time a manufacturer conducts the recall and the FDA notifies the public on its website.

    Approved Drugs illustration
    The number of FDA-approved drug recalls has steadily continued to increase. In 2015, there were more than 4,600 drug and device recalls, and 405 of these products had the potential to cause serious harm or death.

    In the case of medical devices, the FDA has more authority to issue a mandatory recall. But most manufacturers will voluntarily recall the product. Manufacturers may send letters to doctors and physicians notifying them, but patients do not receive letters.

    Before the FDA decides to send a recall request to a manufacturer, it considers several factors and a committee of experts weighs available safety and efficacy data.

    The committee classifies the recall as Class I, II, or III, with III being the most serious. Class III recalled products can lead to serious injury or death.

    How FDA is Funded

    The FDA's funding for drug review is a constant source of controversy. Congress passed the Prescription Drug User Fee Act (PDUFA) in 1992. The PDUFA allowed the FDA to collect fees from drug companies to speed up approvals. Currently, about two-thirds of drug-approval funding comes from pharmaceutical companies.

    In 2015, FDA spent about $1.1 billion on the review of prescription drug applications, according to the Project on Government Oversight. Only 29 percent of that money came from Congress. This means taxpayers funded $331.6 million while drug companies provided the lion's share at $769.1 million.

    Although that lessens the burden on taxpayers, some consumer watchdogs say the costs could be passed on to consumers through higher drug prices.

    More importantly, the FDA may approve products faster under the influence of Big Pharma at the expense of public safety, said Michael A. Carome, director of Public Citizen's Health Research Group.

    Adverse Event Reporting

    After a drug, medical device or vaccine hits the market, the FDA depends on voluntary reporting of manufacturers, hospitals, doctors and patients to track side effects or complications stemming from these products. If a manufacturer receives an adverse event report, it is required to pass this information on to the FDA.

    FAERS, MAUDE and VAERS

    To collect adverse event data, the FDA uses Adverse Event Reporting System (FAERS) for drugs, Manufacturer and User Facility Device Experience (MAUDE) for medical devices and the Vaccine Adverse Event Reporting System (VAERS) for vaccines. The agency uses this data to determine if it needs to take regulatory action on a product that may be dangerous to the public.

    Regulatory actions include: updating safety labels, restricting the use of a drug or device, communicating safety information to the public or removing a product from the market. The FDA rarely requests a product withdrawal.

    FAERS, MAUDE and VAERS data does have limitations, according to the FDA. For instance, because reporting is voluntary, there may be more adverse events than the agency is aware of. There is also no guarantee the side effect is directly related to the drug, device or vaccine.

    Madris Tomes, formerly of the FDA, describes the flaws in the current FDA reporting system

    FDA and Clinical Trials

    While the FDA does not conduct clinical trials, it has the responsibility of protecting clinical trial participants and making sure data is available to the public on ClinicalTrials.gov. The FDA's Office of Good Clinical Practice oversees the ethical treatment of participants in clinical trials.

    The agency also oversees and regulates clinical-trial protocols called Good Clinical Practice (GCP). Researchers for drug companies and others conducting clinical trials refer to these protocols when designing each phase of their clinical trials, particularly if these trials are funded by the National Institutes of Health.

    In January 2017, the NIH and FDA required all NIH-funded clinical trial staff be trained in GCP. These principles help assure the safety, integrity, and quality of clinical trials, according to the FDA.

    FDA Scandals and Controversy

    The FDA is the most powerful agency of its kind in the world, according to Daniel Carpenter, author of Reputation and Power: Organizational Image and Pharmaceutical Regulation at the FDA. It shapes the drug and device industry with its decisions, and many other countries follow the agency's lead.

    Unfortunately, the FDA has had its share of controversy involving corruption and cover-ups.

    Pressured employees

    Employees Pressured to Approve Devices

    Some workers in the medical-device review department of the U.S. Food and Drug Administration (FDA) say they feel pressured to approve devices that they are not sure are safe, according to a new survey reported in the Minneapolis Star Tribune.

    Almost 1,000 FDA employees — 17 percent of the total solicited — took the survey. Of those, 158 survey participants worked in the center for devices. About 25 percent said they felt pressured to approve products “despite reservations about the safety, efficacy or quality of the product.”

    The Vioxx Scandal

    In 2000, one year after the FDA approved Vioxx, a clinical trial identified numerous heart risks associated with the drug, but drug maker Merck downplayed Vioxx’s dangers. In a congressional investigation into how Merck and the FDA handled the Vioxx recall, documents revealed that Merck knew about the severe health complications but heavily marketed the drug anyway.

    Further investigation revealed that the FDA may have acted unethically as well. David Graham, an FDA researcher, testified that the agency subjected him to ostracism, veiled threats and intimidation when he attempted to publish findings that linked Vioxx to 27,000 heart attacks or sudden deaths from 1999 to 2003. In emails Graham produced, his superiors suggested that he water down the study’s conclusions.

    FDA Hides Evidence of Fraud in Clinical Trials

    When the FDA finds evidence that a drug company falsifies information in clinical trial data, it often doesn't report it, according to a study by Charles Seife, a professor at New York University. The study published in JAMA Internal Medicine in 2015 looked at publicly available FDA inspection documents from January 1998 through September 2013.

    Researchers found 57 published clinical trials where the FDA found significant problems but failed to publish these issues or issue corrections.

    The study found:

    False info icon

    22 Trials

    Had false information

    Adverse Events icon

    14 Trials

    Had problems with adverse events reporting

    Protocol violation icon

    42 Trials

    Had protocol violations

    Record Keeping icon

    35 Trials

    Had inaccurate or inadequate record keeping

    Health Icon

    30 Trials

    20 Trials

    Had unspecified violations

    FDA Milestones & History

    Although the agency has faced criticisms, it has a history of protecting the public from health disasters.

    For example, in 1937 after a drug called Elixir Sulfanilamide killed more than 100 people, the FDA sent out agents to physically pull the drug off shelves and advise physicians to stop prescribing it, preventing more loss of life. This led Congress to give FDA more power to regulate drugs.

    In the 1960s, an FDA medical officer named Dr. Frances Kelsey stopped the sale of a sedative called thalidomide in the U.S. after she discovered it had not been properly tested, she did not approve the drug for sale. As a result, she prevented birth defects in the U.S. that happened to thousands of children in other countries.

    The FDA's actions led to the evolution of drug and device regulation laws in the U.S. granting it more regulatory power.
