Comprehensibility of an Over-the-Counter Medicine Leaflet

Abstract

INTRODUCTION: Over-the-counter medicine leaflets include important information, which is not always understood by users. OBJECTIVES: To explore the level of understanding of information stated in over-the-counter medicine leaflets, containing paracetamol as active ingredient. METHODS: A qualitative study was conducted, with semi-structured interviews to 20 adults in charge of children using the medicine. The multidisciplinary team was composed by two physicians, one psychologist, one sociologist and one linguist. It used a leaflet of a medicine containing paracetamol for children older than four years. The study analyzed every response as a yes/no variable according to information comprehension. The leaflet speech features were identified, so as to evaluate the data collected by the interviews. RESULTS: None of the interviewed people understood the dosage, while 30% of them had difficulties regarding contraindications. CONCLUSIONS: It is necessary to perform further comprehensibility studies to identify the difficulties faced by over-the-counter medicine users while reading the leafle.
