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.

Reports on file
From February 2004 to June 2026, FDA received 318 adverse event reports that name Cardenalin. The name is as reporters wrote it. In these reports the drug is a suspect or interacting product.
In the same period, 1,400 further reports name it only as a concomitant medicine. The counts on this page do not include these reports.
FDA received 6 reports in the 12 months to June 2026 and 8 in the 12 months before. FDA releases FAERS data every quarter, so the newest months are not complete. They grow in later releases.
The number of people who use the product is not in the data. A count is not a rate. A count of reports is not a count of events or of patients, because one event can have more than one report.
There are many instances of duplicative reports and some reports do not contain all the necessary information.

Suspect product
FDA records each drug in a report as suspect, concomitant or interacting. This page counts the reports in which Cardenalin is suspect or interacting. FDA says:
Any number of the drugs may be marked as suspect if thought to be responsible for one or more of the reactions, but that information is not validated.

Since the last update
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.

No update is on record for this page. The record starts when FDA adds the reports of July to September 2026.
- In April to June 2026, FDA received 3 reports that name Cardenalin.
- In January to March 2026, FDA received 1.
- In April to June 2025, FDA received 1.
April to June 2026 is the latest closed quarter in the data. A closed quarter is a quarter for which the FDA files have most of the reports.
Reaction lookup
These are the reaction terms that the reports record, with the number of reports for each term. Type a term or a plain word to find its count.
What this list leaves out
The table lists the 32 reaction terms that 5 or more reports record. A term with fewer than 5 reports is not in the table.
This list is partial.
It covers 243 of the 318 reports (76.4%).
The site keeps reaction terms only for years in which the drug has 12 or more reports.
So a count in the table can be lower than the count of FDA.
The table shows all 32 terms.

The counts add to more than 318 reports, because one report can record more than one term. FDA says:
No individual drug is connected to any individual reaction. When a report lists multiple drugs and multiple reactions, there is no way to conclude from the data therein that a given drug is responsible for a given reaction.

MedDRA term
The person who codes a report selects the preferred term that agrees best with the description of the reporter. The words under a term are the plain meaning that this site gives.

An outcome in a report is not proof that the drug was the cause. The reporter gives the outcome, and FDA does not verify it. FDA says:
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.

The six headings with the names of FDA are the outcome terms of FDA. A report can have more than one outcome. The columns Serious and Not serious are the two values of the openFDA field serious. For the value serious, openFDA gives this description:
The adverse event resulted in death, a life threatening condition, hospitalization, disability, congenital anomaly, or other serious condition

The year is the year of the openFDA file that holds the latest version of the report. It is not always the year in which FDA first received the report. The chart of the next section uses the year of first receipt. The latest year is not complete.

Why a count moves
A count moves for many reasons. The guide gives FDA's words about them.

Where the data come from
The counts come from the openFDA Drug Adverse Event (FAERS) bulk files, release of 1 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 Oct 2026. A class is the pharmacologic class (EPC) of the FDA label.
A report is in the count when it names Cardenalin as a suspect or interacting product. The 1,400 reports that name it only as a concomitant medicine are not in the count. 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. See how the site counts reports, the data sources and the corrections page.
Questions
Do these reports show that Cardenalin was responsible for the reactions?
No. FDA says:
For any given report, there is no certainty that a suspected drug caused the event.

No. It is a count of what people reported to FDA: 318 reports from February 2004 to June 2026. The FDA-approved label of a product lists its adverse reactions. The official pages at the end of this page link to the labels.
Who sent these reports?
Physician (48.1%), pharmacist (28.9%) and consumer or non-health professional (8.5%). These are the types of reporter for the reports that name this drug.
