This list of confused drug names, which includes look-alike and sound-alike
name pairs, consists only of those name pairs that have been involved in
medication errors published in the ISMP Medication Safety Alert!® The errors involving these medications were reported to ISMP through the USP-ISMP Medication Errors Reporting Program (MERP).

The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) established a National Patient Safety Goal that requires each accredited organization to identify a list of look-alike or sound-alike drugs used in the organization. Those names that appear on the JCAHO's list of look-alike or sound-alike names have been noted with a double asterisk (**) below.
