The ethics of dietary supplements and natural health products in pharmacy practice: a systematic documentary analysis.
OBJECTIVE
Many natural health products and dietary supplements are purchased in pharmacies and it has been argued that pharmacists are in the best position to provide patients with evidence-based information about them. This study was designed to identify how the pharmacist's role with respect to natural health products and dietary supplements is portrayed in the literature.


METHODS
A systematic search was conducted in a variety of health databases to identify all literature that pertained to both pharmacy and natural health products and dietary supplements. Of the 786 articles identified, 665 were broad-coded and 259 were subjected to in-depth qualitative content analysis for emergent themes.


RESULTS
Overwhelmingly, support for the sale of natural health products and dietary supplements in pharmacies is strong. Additionally, a role for pharmacist counselling is underscored. But another recurrent theme is that pharmacists are ill-equipped to counsel patients about these products that are available on their shelves. This situation has led some to question the ethics of pharmacists selling natural health products and dietary supplements and to highlight the existence of an ethical conflict stemming from the profit-motive associated with sales of natural health products and dietary supplements.


CONCLUSIONS
This analysis raises concerns about the ethics of natural health products and dietary supplements being sold in pharmacies, and about pharmacists being expected to provide counselling about products of which they have little knowledge.
