U.S. Illnesses and Deaths Associated With Compounded Medications or Repackaged Medications

2001-17

This data table was updated in June 2017, to reflect newly reported events.

Pew’s drug safety project has identified more than 50 reported compounding errors or potential errors associated with 1,197 adverse events, including 99 deaths, from 2001 to 2016. Because many such events may go unreported, this chart is likely an underestimation of the number of compounding errors since 2001. Contamination of sterile products was the most common error; others were the result of pharmacists’ and technicians’ miscalculations and mistakes in filling prescriptions.
