The FDA Adverse Event Reporting System (FAERS) is a database that contains adverse event reports, medication error reports and product quality complaints resulting in adverse events that were submitted to FDA. The database is designed to support the FDA's post-marketing safety surveillance program for drug and therapeutic biologic products. The informatic structure of the FAERS database adheres to the international safety reporting guidance issued by the International Conference on Harmonisation (ICH E2B). Adverse events and medication errors are coded using terms in the Medical Dictionary for Regulatory Activities (MedDRA) terminology.

FAERS is a useful tool for FDA for activities such as looking for new safety concerns that might be related to a marketed product, evaluating a manufacturer's compliance to reporting regulations and responding to outside requests for information. The reports in FAERS are evaluated by clinical reviewers, in the Center for Drug Evaluation and Research (CDER) and the Center for Biologics Evaluation and Research (CBER), to monitor the safety of products after they are approved by FDA.

If a potential safety concern is identified in FAERS, further evaluation is performed. Further evaluation might include conducting studies using other large databases, such as those available in the Sentinel System. Based on an evaluation of the potential safety concern, FDA may take regulatory action(s) to improve product safety and protect the public health, such as updating a product’s labeling information, restricting the use of the drug, communicating new safety information to the public, or, in rare cases, removing a product from the market.

Healthcare professionals, consumers, and manufacturers submit reports to FAERS. FDA receives voluntary reports directly from healthcare professionals (such as physicians, pharmacists, nurses and others) and consumers (such as patients, family members, lawyers and others). Healthcare professionals and consumers may also report to the products’ manufacturers. If a manufacturer receives a report from a healthcare professional or consumer, it is required to send the report to FDA as specified by regulations.

The MedWatch website provides information about voluntary and mandatory reporting.

Yes, the FDA Adverse Events Reporting System (FAERS) Electronic Submissions website provides drug and therapeutic biological product manufacturers, distributors, packers, and other interested parties with information about FDA Adverse Event Reporting System (FAERS) electronic submissions and instructions on how to electronically submit post-marketing individual case safety reports (ICSRs), with and without attachments.

Yes, FAERS data does have limitations. First, there is no certainty that the reported event (adverse event or medication error) was due to the product. FDA does not require that a causal relationship between a product and event be proven, and reports do not always contain enough detail to properly evaluate an event. Furthermore, FDA does not receive reports for every adverse event or medication error that occurs with a product. Many factors can influence whether an event will be reported, such as the time a product has been marketed and publicity about an event. There are also duplicate reports where the same report was submitted by a consumer and by the sponsor. Therefore, FAERS data cannot be used to calculate the incidence of an adverse event or medication error in the U.S. population. For more information, please refer to the question What points should I consider while viewing the dashboard content?

FAERS data is available to the public in the following ways:

·        FAERS dashboard: a highly interactive web-based tool that allows for the querying of FAERS data in a user friendly fashion. 

·        FAERS data files: provides raw data consisting of individual case safety reports extracted from the FAERS database. A simple search of FAERS data cannot be performed with these files by persons who are not familiar with the creation of relational databases.  

·        Individual case safety reports from the FAERS database can also be obtained by sending a Freedom of Information (FOI) request to FDA.

To confirm that your report is in FAERS, please send a Freedom of Information (FOI) request to FDA.

This tool makes the data easier to query and produces user-friendly information and charts. For example, users can view a summary of adverse event reports received from 1968 to the present or for a specific timeframe. In addition, users can search for products or reactions of interest within a specific timeframe.

Yes, a recorded webinar is available which reviews the capabilities, and limitations, of the FAERS public dashboard.

Please note that a new webinar addressing the version 2.0 updates to the FAERS Public dashboard will be available soon.

Yes, but the user interface layout may not be very user friendly. FDA will continue to work on the dashboard to make the user interface Android and iPhone friendly.

Yes, you will be able to export a limited set of search data to an Excel^® spreadsheet and then download it. FDA will still continue to provide the FAERS Latest Quarterly Data Files online.

·        Potential Signals of Serious Risks/New Safety Information Identified from the FDA Adverse Event Reporting System (FAERS): quarterly reports on potential serious side effects identified by FAERS.

·        Post-marketing Drug and Biologic Safety Evaluations: provides summary information about ongoing and completed post-marketing safety evaluations of adverse experience reports made to FDA for New Drug Applications (NDAs) and Biologic License Applications (BLAs) approved since September 27, 2007.

Each unique submission of a case received is assigned a version number (for example, Case #1234567, version 1). The initial version received will be version 1. If a follow up is received on a previously submitted case, then that version of the case will be version 2, and so on. The latest version of a case represents the most current information about that case.

The data is updated quarterly. Dates for upcoming dashboard updates are shown below:

When you view the website output of reported reactions (side effects or adverse drug reactions) for a drug product, it is important to consider the following points:

• Data Quality: There are many instances of duplicative reports and some reports do not contain all the necessary information. Duplicate reporting occurs when the same report is submitted by the consumer and the sponsor. The information in FAERS evolves daily and the number of individual cases may increase or decrease. It is therefore possible that the information on this website may change over time.

• Existence of a report does not establish causation: For any given report, there is no certainty that a suspected drug caused the reaction.  While consumers and healthcare professionals are encouraged to report adverse events, the reaction may have been related to the underlying disease being treated, or caused by some other drug being taken concurrently, or occurred for other reasons. The information in these reports reflects only the reporter's observations and opinions.

• Information in reports has not been verified: Submission of a report does not mean that the information included in it has been medically confirmed nor is it necessarily a conclusion from the reporter that the drug caused or contributed to the event.

• Rates of occurrence cannot be established with reports: The number of suspected reactions in FAERS should not be used to determine the likelihood of a side effect occurring. The FDA does not receive reports for every adverse event or medication error that occurs with a product. Many factors can influence whether an event will be reported, such as the time a product has been marketed and publicity about an event. Therefore, information in these reports cannot be used to estimate the incidence (occurrence rates) of the reactions reported.

• Patients should talk to their doctor before stopping or changing how they take their medications.

• Patient Outcomes received in FAERS: These data describe the outcome of the patient as defined in U.S. reporting regulations (21 CFR 310.305, 314.80, 314.98, 600.80). Serious means that one or more of the following outcomes were documented in the report: death, hospitalization, life-threatening, disability, congenital anomaly, and/or other serious outcome. Documenting one or more of these outcomes in a report does not necessarily mean that the suspect product(s) named in the report was the cause of the outcomes.

Importantly, the FAERS data by themselves are not an indicator of the safety profile of the drug.

The best sources of information for the known side effects of a drug are the FDA approved product information (also known as full prescribing information or US package insert) and your health care provider. This dashboard tells you what was reported to the FDA, but it is difficult to know what caused a particular event in a particular patient from the information on the dashboard. Even if a symptom is a known side effect for a drug, it can be difficult to know if the symptom that a patient had was caused by a particular drug, since there may be other possible causes as well. For example, some medications cause headaches, but many people have headaches even when they aren’t on any medications.

Although some adverse events can be caused by a drug, there are also other possible explanations for symptoms that appear while a patient is taking a drug. For example, the adverse event could be related to a disease that a patient already has, something in the environment, diet, or sleep habits, to name a few, could cause symptoms that could be misinterpreted as adverse events caused by a drug.

Although it is difficult to generalize, it is unlikely that every adverse event reported for a given drug was caused by that drug.

The FAERS dashboard should not be used to determine the safety profile of one drug compared to another. Even identical drug products can have widely differing levels of adverse event reporting due to the voluntary nature of the reporting system.

The same caution that applies to all of the FAERS reports, should be applied to death reports. The existence of a death report in the FAERS dashboard does not mean that the drug caused the person to die. Fatal outcome could be from the natural progression of the disease being treated.

No. The FAERS database contains only a small fraction of the side effects that occur with a drug. This is due to a variety of reasons. Most importantly, there is no requirement for healthcare professionals and consumers to report side effects to either the FDA or to the manufacturer. Even for side effects that have been reported to the manufacturer, only certain categories of adverse events are required to be submitted to the FDA. Lastly, there are a variety of factors that can cause more or less reporting to both the FDA and manufacturers, including whether a particular side effect is known for a drug, how long a drug has been on the market and even whether there have been recent news reports about possible side effects for a given drug or a group of drugs.

An adverse event (AE) is any symptom that occurs while taking a drug, which may or may not have been caused by the drug. This is different from an adverse drug reaction (ADR), where there is specific evidence that the AE is related to the drug. A side effect is the same as an ADR. As a result, ADR is always an AE, but an AE may or may not be an ADR.

You should always check with your healthcare provider before discontinuing any medication that you have been prescribed.

You should check with your healthcare provider if you have any concerns about a medication that you are taking. You and your healthcare provider should decide if the potential benefits of you taking a particular drug outweigh its potential risks as well as the risks of an illness being left untreated.

Please consult with your health care provider to discuss the safety profile and the overall benefit-safety balance of the drug.

The Home page displays the count of reports received each year and quarter by the FDA. This includes both initial and follow-ups reports submitted in FAERS.

In Q4 2021, the FAERS system was modernized and the data was migrated to a new database. The new database handles deletion of report submissions slightly differently compared to the previous system. Whenever a case is deleted, the previous system deleted only the latest follow-up report for the case and left the older reports in the case untouched. As a result, the counts displayed in the Home page included older reports for deleted cases. However, in the new FAERS database currently in use, all reports (initial and follow-ups) for a case are deleted upon the deletion of a case. Because of this, the counts of reports displayed in the Home page are now reduced compared to previous iterations of the FAERS Public Dashboard.

As an example, the comparison below highlights the difference in counts of reports for Q1 2021 before and after the data refresh for Q4 2021.

Q1 2021 report count before the data refresh for Q4 2021:

Q1 2021 report count after the data refresh for Q4 2021:

No. You will not be able to view any data in the dashboard without accepting the disclaimer.

Data in the FAERS Public Dashboard is as of September 30, 2024. Data is updated quarterly.

Each case might have more than one reaction term. Therefore, the sum of the case counts for individual reactions may be same or more than the total count of distinct cases.

Each case might have more than one outcome. Therefore, the sum of counts for individual outcomes may not match the total count of distinct cases.

The “Listing of Cases” table allows you to scroll vertically or horizontally using vertical and horizontal scroll bars respectively. To view the scroll bars, hover over the listing of cases table.

·      Scroll up or down in the Listing of Cases table using the vertical scroll bar on the right side of the table. This will allow you to see all the rows in the table.

·      Scroll to the left or right in the Listing of Cases table using the horizontal scroll bar on the bottom of the table. This will allow you to see all the columns in the table.

Yes, you may rearrange columns by dragging and dropping column headers anywhere in the table. To move a particular column:

1.  Click and hold on the column header.

2.  Drag it next to a column you want to move it to and release the click.

Due to space constraints, some cells display only partial data. To view the entire content of any cell, simply hover over the cell with your mouse. The entire content of the cell appears in a pop-up.

You can filter and sort data in the table using any column or any value in a cell. To filter using a value in cell, simply click on the cell. The table is refreshed with the filtered data. To filter using a column, click on the  icon next to the column header, and then select from the list of values for that column.

To sort data using a specific column, simply click on the column header. Click once on the column header to view data in ascending order. Click again on the column heading to sort the values in descending order.

You can download data from the “Listing of Cases” table to a Microsoft Excel (.xlsx) file by using the “Export data” option.
