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
HMG-CoA reductase inhibitor is a pharmacologic class: an FDA Established Pharmacologic Class. The class has 13 drug pages on this site.
From January 2004 to June 2026, FDA received 204,462 adverse event reports that name a drug of the class. In these reports the drug is a suspect or interacting product. A report that names two drugs of the class counts one time for each.
FDA received 6,978 reports in the 12 months to June 2026 and 7,503 in the 12 months before. FDA releases FAERS data every quarter, so the newest months are not complete. They grow in later releases.
Of the 1,332,454 drug reports that FDA received in the 12 months to June 2026, 6,978 (0.5%) name a drug of the class. Reports from consumers or other non-health professionals were 35.7% of the reports that name a drug of the class and 45.8% of all drug reports.
The number of people who use the product is not in the data. A count is not a rate.
Pharmacologic class
The Established Pharmacologic Class (EPC) of FDA is the class on the label of a drug. The site puts a drug in the class that its reports have most often.

Reaction lookup
These are the reaction terms that the reports of the class record. Type a term or a plain word to find its count.
What this list leaves out
The table lists the 3,335 reaction terms that 5 or more reports record. A term with fewer than 5 reports is not in the table.
The site keeps reaction terms for 203,938 of the 204,462 reports (99.7%).
The reports of the other years are not in the counts.
So a count in the table can be lower than the count of FDA.
The table shows the first 50 of 3,335 terms.

The counts add to more than 204,462 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.

Reports by month
FDA releases FAERS data every quarter, so the newest months are not complete. They grow in later releases.
Outcomes, patients and reporters

| Death | 13,359 | 6.5% | |

| Other Serious (Important Medical Events) | 111,163 | 54.4% | |
| Not serious | 53,144 | 26% |
An outcome in a report is not proof that a drug was the cause. The reporter gives the outcome, and FDA does not verify it. A report can have more than one outcome. 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.

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 class of a drug is the Established Pharmacologic Class that openFDA attaches to its reports most often. When the reports have none, it is the class in the NDC Directory. 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.
