FDA received 53,596 drug adverse event reports in December 2010, against 38,901 in the same month a year earlier and a monthly average of 39,091 over the preceding 12 months. The MAUDE device database received 31,875 reports that month (21,573 a year earlier).

The drugs listed most often as suspect products were Enbrel (18,349), Tracleer (2,669) and Crestor (2,362), and the reactions recorded most often were death (6,264), injection site pain (3,920) and injection site erythema (3,197).

Relative to their own average over the preceding 12 months, the drugs whose report count rose most were Bosentan Tablet Unknown Us Mg (51.9× its average), Tracleer (29.2× its average) and Remodulin (22.7× 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.

FDA states that adverse event reports "represent a small percentage of total usage numbers of a product", that "common products may have a higher number of adverse events due to the higher total number of people using the product", and that the data "by themselves are not an indicator of the safety profile of the drug or biologic."

Questions about December 2010

How many adverse event reports did FDA receive in December 2010?

53,596 drug reports are in the openFDA FAERS release of 28 Sep 2026, and 31,875 device reports in the MAUDE release of 28 Sep 2026. The same month a year earlier has 38,901 drug reports.

Which drugs were listed most often?

Enbrel (18,349), Tracleer (2,669), Crestor (2,362), Tysabri (1,887) and Lyrica (1,826).

Which reactions were recorded most often?

death (6,264), injection site pain (3,920), injection site erythema (3,197), drug ineffective (2,078) and headache (1,951).

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.
