ISMP's List of Confused Drug Names.

Horsham, PA; Institute for Safe Medication Practices: February 2019.

Drawing on information gathered from the ISMP Medication Errors Reporting Program, this fact sheet provides a comprehensive list of commonly confused medication names, including look-alike and sound-alike name pairs. Drug name confusion can easily lead to medication errors, and the ISMP has recommended interventions such as the use of tall man lettering in order to prevent such errors. An error due to sound-alike medications is discussed in this AHRQ WebM&M commentary.
