Knowledge and perceptions of community patients about generic medicines

BACKGROUND: Patients’ knowledge and perceptions about generic medicines are extremely important for promoting generic substitution. Few studies have investigated patients’ acceptance or understanding of generic medicines. AIM: To explore knowledge and perceptions of community patients about generic medicines. METHOD: A self-administered anonymous survey was completed by patients presenting at 1 of 18 community pharmacies in Adelaide, South Australia. The questionnaire comprised items on: demographics (age, gender, ethnicity, education, income, self-rated health status), safety, effi cacy, cost and value of generic medicines, and patients’ willingness to use these. RESULTS: 503 patients completed the survey – 51% females and 49% males. 60% of patients were on more than one prescription medication. 67% of patients rarely asked for a generic medicine when their prescriptions were being fi lled. Around 47% of patients believed that they needed more information on the difference between generic and brandname medicines. Around 81% of patients knew that generic medicines were less expensive than brand-name medicines; and 51% believed generic medicines offered better value. When asked whether ‘they would rather take generic medicines than brand-name medicines’ – about 30% indicated they would, 25% would not, 40% were neutral and 5% did not provide an answer. Younger patients (55 years or less) asked for generic medicines more often than older patients (over 55 years) (p < 0.05). There were no other signifi cant differences. CONCLUSION: Most patients had some knowledge about generic medicines. However, many were unsure if they preferred generic to brand-name medicines or brand-name to generic medicines.Rafie Ibrahim, Ross A. McKinnon and Suong N.T. Ng
