Look-Alike Drug Names with Recommended Tall Man Letters
ISMP List of Look-Alike Drug Names with Recommended Tall Man Letters contains drug name pairs and trios with recommended, bolded tall man (uppercase) letters to help draw attention to the dissimilarities in look-alike drug names. The list includes mostly generic-generic drug name pairs, although a few brand-brand or brand-generic name pairs are included. The US Food and Drug Administration (FDA) list of drug names with recommended tall man letters was initiated in 2001 with the agency’s Name Differentiation Project.
Table 1 provides an alphabetized list of FDA-approved established drug names with recommended tall man letters.
Table 2 provides an alphabetized list of additional drug names with recommendations from ISMP regarding the use and placement of tall man letters. This is not an official list approved by FDA. It is intended for voluntary use by healthcare practitioners, drug information vendors, and medication technology vendors. Any product label changes by manufacturers require FDA approval.
