Natural health products such as herbs, vitamins and homeopathic medicines are widely available in Canadian pharmacies. Purpose: to conduct a systematic analysis of Canadian pharmacy policies and guidelines to explore pharmacists' professional responsibilities with respect to natural health products. Methods: Legislation, codes of ethics, standards of practice and guidance documents that apply to the practice of pharmacy in each Canadian jurisdiction were systematically collected and examined to identify if, and how, these instruments establish professional duties in regard to natural health products. Results: The majority of Canadian jurisdictions now include some explicit reference to natural health products in standards of practice policy or guideline documents. Often natural health products are simply assumed to be included in the over-the-counter (OTC) product category and thus professional responsibilities for OTCs are relevant for natural health products. A minority of provinces have specific policies on natural health products, herbals or homeopathy. In addition, the National Association of Pharmacy Regulatory Authorities' Model Standards of Practice specifically refers to natural health products. Most policy documents indicate that pharmacists should inquire about natural health product use when counselling patients and, when asked, should provide accurate information regarding the efficacy, toxicity, side effects or interactions of natural health products. Public messaging also indicates that pharmacists are knowledgeable professionals who can provide evidence-based information about natural health products. Conclusions: Explicit policies or guidelines regarding pharmacists' professional responsibilities with respect to natural health products currently exist in the majority of Canadian jurisdictions.
