What is the purpose of tall man letters in pharmacy?

Tall man letters are specifically designed to aid in the prevention of errors that occur due to sound-alike or look-alike medications. These medications can often be confused with one another when prescribed or dispensed, leading to potentially harmful mistakes. By using tall man lettering—highlighting part of the drug name in uppercase—pharmacy professionals can quickly identify distinct medications at a glance. For instance, the distinction between "prednisone" and "prednisolone" is made clearer, reducing the risk of mix-ups during the medication dispensing process. This practice serves as a visual cue that enhances safety in medication management and supports proper patient care. Using tall man letters is an important step in minimizing medication errors in a busy pharmacy setting.
