Abstract
Objective: To evaluate the understanding of the drug package insert by drug users. Methods: The study population consisted of 232 drug users, of both sexes, aged 18 to 70 years. Data collection was carried out through a questionnaire, with multiple choice objective questions. The collected data were evaluated using the SPSS 20.0 program (Statistical Package for the Social Sciences) for Windows. The Chi-square test was used to assess differences in proportions of categorical data, with p≤0.05 being considered significant. Results: Of the interviewees, 51.7% were male and 48.3% female, and the majority, 22.4% were between 50 and 59 years old. 85.3% have already resorted to the package leaflet to clarify any doubts and 38.8% are in the habit of consulting the package leaflet before using the medication. 43.5% use electronic bulbs and 66.8% understand the physical package insert better. 34.1% cannot understand the explanations on the label 48.7% think the language of the label is very technical. Conclusion: Even with the adaptations of RDC 47, the package insert still needs to go through evolutionary processes in order to make it more direct and objective, with less technical languages and slightly larger letters, facilitating consumer understanding.
