【 摘 要 】

Background

Menopause is a natural phase in a woman’s aging process, characterized by the cessation of menstruation. Women who are going through the menopause transition can experience physiological symptoms that significantly impact their quality of life. Concern about adverse effects of traditional hormone therapy often leads women to purchase over-the-counter (OTC) natural health products (NHPs). The goal of this study was toinvestigate the range of OTC NHPs for menopause available to Canadian women, and the packaging information they can access to make self-management decisions.

Methods

Edmonton stores belonging to each of nine Canadian pharmacy chains were visited to identify NHPs marketed for the relief of menopausal symptoms. Details were extracted from the packaging: a) product name and manufacturer, b) Health Canada license number, c) medically active ingredients, d) claims of efficacy, e) contra-indications and warnings, and f) daily cost. Data were entered and analyzed using Microsoft Excel.

Results

We identified 20 OTC NHP menopausal products, 19 of which had Health Canada license numbers. Twenty-eight medically active ingredients were identified, with the most common being black cohosh (in 14 products) and soy isoflavones (n = 7), chaste tree (n = 5), and dong quai (n = 3). Most products claimed they would relieve vasomotor symptoms, including hot flashes (n = 14) and night sweats (n = 10). Each product had a labeled contraindication for at least one specific condition. Costs per recommended daily dose ranged from $0.07 to a maximum of $2.50 (CAD$).

Conclusion

Natural health products for menopausal symptoms are easily available to Canadian women. The lack of clear evidence of product efficacy makes the need for easily accessible, balanced information on this topic important for women to make well informed choices.
