RT Journal A1 Wang B, Gagne JJ, Choudhry NK T1 THe epidemiology of drug recalls in the united states JF Archives of Internal Medicine JO Archives of Internal Medicine YR 2012 FD July 23 VO 172 IS 14 SP 1110 OP 1111 DO 10.1001/archinternmed.2012.2013 UL http://dx.doi.org/10.1001/archinternmed.2012.2013 AB On January 31, 2012, Pfizer recalled nearly 1 million packs of birth control pills because of concerns that inert and active pills were miscounted and incorrectly ordered in their blister packs.1 This and other recent recalls highlight concerns about the potential clinical impact of defective and otherwise compromised drug products. However, little is known about the public health burden of drug recalls and whether health care providers are properly notified about clinically important recalls. We sought to quantify the frequency, cause, and extent of distribution of drug recalls in the United States and to evaluate the processes by which the US Food and Drug Administration (FDA) communicates clinically important recall information to health care providers.
