Tall Man Lettering

Medicine name confusion contributes to thousands of medication errors each year [1], some causing significant patient harm [2].

The risks associated with medicine name confusion can be reduced through the application of Tall Man Lettering. Tall Man Lettering 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.

In 2015, the Hospital Pharmacy Product List (HPPL) was updated to include Tall Man Lettering. While pharmacy and nursing staff are the primary clinicians exposed to Tall Man Lettering, any staff members that may be exposed to Tall Man Lettering should be made aware of its purpose and benefits.
