Supply of over-the-counter weight-loss products from community pharmacies

Abstract

The aim was to ascertain the availability of over-the-counter (OTC) weight-loss products from community pharmacies and other retail outlets in a large conurbation, and to determine the knowledge and practices of pharmacy staff in the supply of OTC weight-loss products. The setting was one primary care trust in England. We used a cross-sectional survey of 123 community pharmacies, 12 health stores and 64 supermarkets, plus telephone interview of the pharmacists. Over two-thirds of community pharmacies (69%) and health stores (67%) but few supermarkets (8%) stocked one or more OTC weight-loss products. In total, 73 different products were available from pharmacies, most of which (50) were claimed by manufacturers to be appetite suppressants. Seventy-eight pharmacists were interviewed, of whom 57 stocked OTC weight-loss products. Of these 57, only two claimed to undertake any measurements before supplying the products and 33 had no supporting materials/information about the products, although 38 claimed to provide advice. None of the 57 pharmacists had undertaken any specific training in relation to weight loss. Only 44% of all those interviewed considered OTC weight-loss products to be useful, with even fewer (35%) considering them to be safe. Community pharmacies are a major distributor of OTC weight-loss products, despite the lack of evidence of their efficacy and concerns about their safety. Many pharmacists had limited knowledge of the products, placed few restrictions on their supply and viewed training in weight loss as unnecessary. Pharmacists should consider the appropriateness of supplying these products and utilize the opportunities presented to support weight reduction by more effective means.
