Remedy or cure? Lay beliefs about over-the-counter medicines for coughs and colds.

Abstract

BACKGROUND: Over 500 million is spent in the United Kingdom every year on over-the-counter medicines for coughs and colds. Evidence for their pharmacological efficacy is lacking. AIM: To examine lay beliefs about over-the-counter medicines for coughs and colds. To explore whether the distinction between symptom relief and cure has the same relevance to lay people as it does to medical professionals. DESIGN OF STUDY: Small pilot study using qualitative techniques. SETTING: Variety sample of 11 patients attending the National Health Service walk-in centre, Birmingham, England. METHOD: In-depth semi-structured interviews, including pile-sorting and fictional case histories, were used to explore participants' beliefs about the effects of over-the-counter medicines on coughs and colds. RESULTS: Eight of the 11 participants believed that at least one over the-counter cough medicine (most frequently Benylin for Chesty Coughs) could shorten, or "cure", an illness. Five participants thought that the majority of the medicines that they recognised would speed recovery rather than just relieve symptoms. CONCLUSIONS: There is a common confusion in the lay person's mind between the ability of a medicine to relieve symptoms, and its ability to cure a disease or to hasten recovery. This misunderstanding may affect the demand for primary care consultations.
