DeHenau C, Becker MW, Bello NM, et al. Tallman lettering as a strategy for differentiation in look-alike, sound-alike drug names: the role of familiarity in differentiating drug doppelgangers. Appl Ergon. 2016;52:77-84. doi:10.1016/j.apergo.2015.06.009.
This study found that tall man lettering—in which specific letters in drug names are printed in capital letters to avoid being mistaken for a look-alike or sound-alike medication—led to more effective detection of changes between drugs by health care professionals and consumers. A prior WebM&M commentary discussed tall man lettering as one strategy for improving the safety of look-alike and sound-alike medications.
