Tall Man lettering

Tall man lettering (tall-man lettering or tallman lettering) is the practice of writing part of a drug's name in upper case letters to help distinguish sound-alike, look-alike drugs from one another in order to avoid medication errors.[1][2] For example, in tall man lettering, "prednisone" and "prednisolone" should be written "predniSONE" and "predniSOLONE", respectively. The Office of Generic Drugs of the U.S. Food and Drug Administration (FDA) encourages manufacturers to use tall man lettering labels to visually differentiate their drugs' names,[1] and a number of hospitals, clinics, and health care systems use tall man lettering in their computerized order entry, automated dispensing machines, medication admission records, prescription labels, and drug product labels.[3]
