Confused Drug Names
| CONFUSED DRUG NAMES | |
|---|---|
|
This list of confused drug names, which includes look-alike and sound-alike name pairs, consists of those name pairs that have been published in the Institute for Safe Medication Practices' (ISMP) ISMP Medication Safety Alert! and the ISMP Medication Safety Alert! Community/Ambulatory Care Edition. Events involving these medications were reported to ISMP through the ISMP National Medication Errors Reporting Program (ISMP MERP). This list can be used to determine which medications require special safeguards to reduce the risk of errors. This may include strategies such as: using both the brand and generic names; including the purpose of the medication on prescriptions; configuring computer selection screens to prevent look-alike names from appearing consecutively; and changing the appearance of look-alike product names. |
