Drug and device reports that FDA received, by year

What a report is

A report is not proof that a medicine or a device was the cause of an event.

FDA says:

Adverse event reports submitted to FDA do not undergo extensive validation or verification. Therefore, a causal relationship cannot be established between product and reactions listed in a report. While a suspected relationship may exist, it is not medically validated and should not be the sole source of information for clinical decision making or other assumptions about the safety or efficacy of a product. Additionally, it is important to remember that adverse event reports represent a small percentage of total usage numbers of a product. Common products may have a higher number of adverse events due to the higher total number of people using the product.

FDA also says:

There is no certainty that the reported event (adverse event or medication error) was actually 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. The information in these reports has not been scientifically or otherwise verified as to a cause and effect relationship and cannot be used to estimate the incidence of these events.

Do not rely on openFDA to make decisions regarding medical care. While we make every effort to ensure that data is accurate, you should assume all results are unvalidated.

FDA says:

MDR data alone cannot be used to establish rates of events, evaluate a change in event rates over time or compare event rates between devices. The number of reports cannot be interpreted or used in isolation to reach conclusions about the existence, severity, or frequency of problems associated with devices.

FDA releases MAUDE data every month. Reports can arrive months after an event, so the newest months grow in later releases.

How the figures were made

The year is the year in which FDA received the report, not the year of the event. A later release of the data can change the count of a year, because a report can arrive late or have a new version.

The two systems are separate. FAERS has the reports about drugs, and MAUDE has the reports about medical devices.

A count is a count of reports, not of events or of patients, and it is not a rate.

A program makes this page from the openFDA files with fixed sentence rules. See how the site counts reports and the data sources.

In earlier editions

This table is in the edition of October 2026, the first edition. Each month adds an edition that keeps the first rows of the table as they were.
