The Commission is responsible for the development and stewardship of the National Tall Man Lettering List (the List). The Commission developed the List to help clinicians reduce the risk of medicine selection errors for medicines with look-alike, sound-alike (LASA) medicine names.
The List compiles LASA medicine name pairs (generic and brand name pairs) that have been predicted to pose the greatest risks to patient safety.
The Commission has revised the National Tall Man Lettering List, initially published in 2011. The updated List reflects the changes to the Australian Register of Therapeutic Goods, international Tall Man lettering lists, International Harmonisation of Ingredient Names and reported adverse incidents or near misses from hospital networks across Australia.
The List shows LASA medicine names in pairs or groups. The medicines names have Tall Man lettering applied to them consistent with the national convention and should be used in the form provided.
The Commission supports the use of Tall Man lettering as part of a multi-faceted approach to reduce the risk of selection errors by health professionals associated with LASA medicines names.
Tall Man lettering should be used by clinicians and health service organisations in:
Tall Man lettering is a typographic technique that uses selective capitalisation to help make similar-looking (LASA) medicine name pairs easier to differentiate. It uses a combination of lower- and upper-case letters to highlight the differences between look-alike medicine names, helping to make them more easily distinguishable.
The List compiles LASA medicine name pairs (generic and brand name pairs) that have been predicted to pose the greatest risks to patient safety. For example:
|rifaMPICin and rifaXIMin||proGRAF and proZAC|
Tall Man lettering reduces error by warning clinicians about the risk of confusing medicine names. It also helps clinicians select the right product in electronic systems or from shelves.
Details of the original methodology and development of the National Tall Man Lettering List in 2011 are available from the National Standard for the Application of Tall Man Lettering Project Report.
Evaluating the Effect of the Australian List of Tall Man Names assessed the effect of Tall Man lettering on the confusability of medicines names, and determined if Tall Man lettering increased the rate of error.
Implementing Tall Man lettering in Australia is encouraged by some, but the lack of standards for its application has been a significant barrier.
The Commission developed the National Tall Man Lettering List to:
The Commission expects that it will be widely adopted into electronic health initiatives and standards. The National guidelines for on-screen display of clinical medicines Information and guidance for implementation of Electronic medication management systems published by the Commission recommend using Tall Man lettering.
The development of the Tall Man Lettering is described in the Journal of Evaluation in Clinical Practice.

As part of the National Tall Man Lettering List stewardship, the Commission encourages frontline clinicians to report any adverse incidents or near-misses related to LASA medicine pairs. Issues notified to the Commission are logged in the National Tall Man Lettering Issues Register and are reviewed by the National Tall Man Lettering Expert Advisory Panel (the panel).
The panel is responsible for making recommendations on the medicine name pairs that need to be included in the National Tall Man Lettering List. The panel follows a systematic process to decide on the medicine name pairs that would most benefit from the application of Tall Man lettering.
A report containing information on the outcomes of the panel’s consideration of issues that were addressed in the National Tall Man Lettering List 2017 is available below:
This report also contains information about the rationale for the general revision of the National Tall Man Lettering List.
The Commission invites requests for changes to the National Tall Man Lettering List, which can be made to your state or territory representative on the Health Service Medication Expert Advisory Group. Requests should be accompanied by evidence of confusion, including other possible factors contributing to the risk of patient harm.
