title: Factors that influence Italian consumers' understanding of over-the-counter medicines and risk perception.
abstract: OBJECTIVE
  To evaluate information needs for safe self-medication we explored the Italian consumers' functional health literacy, specific knowledge and risk awareness about over-the-counter (OTC) medicines.
  
  
  METHODS
  A survey was conducted in the health sections of six large super stores. Data were collected from a convenience sample of 1.206 adults aged 18 years and older through a self-administered questionnaire.
  
  
  RESULTS
  Around 42% confused the concept of "contraindications" with that of "side effects" and were unable to calculate simple dosages. Most respondents were aware of the OTC general potential for side effects but 64.3% did not know that people with high blood pressure should use painkillers with cautions and 14.0% and 20.0% were unaware of the risks of long-term use of laxatives and nasal decongestants respectively. Higher total scores were obtained from women, highly educated people and those citing package leaflets as information sources.
  
  
  CONCLUSIONS
  The study, the first of this type in Italy, showed an incomplete awareness of several risk areas, with regard to drug interactions and misuse/abuse.
  
  
  CONCLUSIONS
  The results of this study were the basis of a following intervention plan tailored to the observed consumer needs and including information tools for customers and courses for the retail pharmacists.
