Informa(c)tion. How to do things with medicine information leaflets

This paper analyses how Patient Information Leaflets (PILs) of over-the-counter medical products convey information. More precisely, the article focuses on “instructions” on how to use medicines and related “instructional information” (Trimble 1985). The latter is used in PILs to explain why consumers should follow the instructions. The aim is to show, then, how and whether the PILs sampled help consumers to translate effectively the information contained into actions. The first part of the article examines the deontic devices employed in 8 English and Italian PILs of the most common over-the-counter medicines for human consumption used to relieve the same symptoms. The second part, instead, analyses whether and how the eight leaflets sampled followed the ‘instructions’ contained in one of the authoritative works by Sless and Shrensky in this field (2006). Both Australian authors, indeed, provide useful advice on how to write directives and related explanations in PILs.
