Read first · FDA's statement on these data

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. openFDA, FDA

FDA adds: "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 "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.

18,944
drug reports received: 22,584 a year earlier; 19,499
monthly average, preceding 12 months: -2.8% against the average; 9,446
device reports received: 8,015 a year earlier

FDA received 18,944 drug adverse event reports in October 2006, against 22,584 in the same month a year earlier and a monthly average of 19,499 over the preceding 12 months. The MAUDE device database received 9,446 reports that month (8,015 a year earlier).

The drugs listed most often as suspect products were Advair Hfa (1,693), Lunesta (618) and Lyrica (592), and the reactions recorded most often were drug ineffective (1,206), pharmaceutical product complaint (856) and dyspnoea (801).

Relative to their own average over the preceding 12 months, the drugs whose report count rose most were Levemir (9.7× its average), Avapro (8.7× its average) and Abciximab (6× its average). A jump in one month usually reflects a batch of reports from a manufacturer, a publicised event or a new product, not a change in what happens to patients.

Questions about October 2006

How many adverse event reports did FDA receive in October 2006?

18,944 drug reports are in the openFDA FAERS release of 28 Sep 2026, and 9,446 device reports in the MAUDE release of 28 Sep 2026. The same month a year earlier has 22,584 drug reports.

Which drugs were listed most often?

Advair Hfa (1,693), Lunesta (618), Lyrica (592), Neurontin (476) and Bextra (406).

Which reactions were recorded most often?

drug ineffective (1,206), pharmaceutical product complaint (856), dyspnoea (801), nausea (670) and dizziness (625).

Can the count for a month still change?

Yes. FDA releases FAERS data quarterly, so the newest months are incomplete and grow in later releases. Older months change little.

Does a busy month mean something happened that month?

Not by itself. The date is when FDA received the report, not when the event occurred, and volume follows manufacturer batches, product launches and publicity. FDA states that "a causal relationship cannot be established between product and reactions listed in a report" and that for any given report "there is no certainty that a suspected drug caused the event."

Where this comes from. Counts are built from the openFDA Drug Adverse Event (FAERS) bulk export released 28 Sep 2026, which holds reports FDA received through 30 Jun 2026. Drug names are as reported, resolved to the brand or generic name on the FDA label where openFDA's harmonisation matched them; classes are the pharmacologic class (EPC) from the label and the National Drug Code Directory of 17 Sep 2026. No report narrative, lot number, patient detail or reporter identity is published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
