February 2020 adverse event reports that FDA received in the month
What a report is
A report is not proof that the drug was the cause of the 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.

Where the data come from
The counts come from the openFDA Drug Adverse Event (FAERS) bulk files, release of 29 Oct 2026. The files have the reports that FDA received through 30 Jun 2026. A drug name is the name on the report. The site matches it to a brand name or a generic name of the National Drug Code Directory of 2 Nov 2026. A class is the pharmacologic class (EPC) of the FDA label.
The device counts come from the openFDA Device Adverse Event (MAUDE) bulk files, release of 23 Oct 2026. The files have the reports that FDA received through 30 Sep 2026. The site does not publish a report narrative, a lot number, a detail of a patient or the identity of a reporter. The record of FDA is the authority.

Questions
Can the count for February 2020 change?
Yes. FDA releases FAERS data every quarter, so the newest months are not complete. They grow in later releases. This page has the count of the openFDA release of 29 Oct 2026: 120,299 drug reports.
Does a month with many reports mean that something occurred in that month?
Not by itself. The date is the date on which FDA received the report, not the date of the event. FDA says:
Many factors can influence whether or not an event will be reported, such as the time a product has been marketed and publicity about an event.

How does a person report an adverse event?
FDA runs MedWatch, a program that takes voluntary reports from health professionals, patients and consumers. The guide on how to report has the links.
