In New Zealand, we are lucky enough to have an industry code of ethics for pharmacists, published by the Pharmacy Council of New Zealand, which holds pharmacists to high ethical standards. This code of ethics is the Safe Effective Pharmacy Practice Code of Ethics. One of the most important parts of this code of ethics is section 6.9, which states:
[PHARMACISTS] MUST:… Only purchase, supply or promote any medicine, complementary therapy, herbal remedy or other healthcare product where there is no reason to doubt its quality or safety and when there is credible evidence of efficacy.
Pharmacy Council’s Safe Effective Pharmacy Practice Code of Ethics Section 6.9
The Pharmacy Council of New Zealand isn’t a voluntary member organisation like the Pharmacy Guild or the Pharmaceutical Society. Instead the council is established as part of the Health Practitioners Competence Assurance Act 2003. Their roles are set out in this act and include:
- Registering pharmacists
- Reviewing and maintaining the competence of pharmacists
- Setting standards of clinical competence, cultural competence, and ethical conduct for pharmacists
Which means that the Safe Effective Pharmacy Practice Code of Ethics is not a voluntary code of ethics. It is published by the body whose legal duty it is to set the standards of ethical conduct for pharmacists. Yet all over New Zealand, many pharmacists ignore it.
Walk into any New Zealand pharmacy. Chances are that you will find a section where they advertise and sell a range of homeopathic products. To anyone familiar with the evidence for homeopathy, it will come as no surprise when I tell you that there is no credible evidence of efficacy for any homeopathic product. Therefore, it seems to me, New Zealand pharmacists have an ethical obligation not to promote or sell them.
Yesterday, the Australian National Health and Medical Research Council (NHMRC) issued their final statement on homeopathy, following an incredibly extensive and rigorous review of the literature. They looked at over 1,800 scientific papers, and found that 225 met their criteria for methodological rigour, sample size, and placebo control. Their main finding was:
there are no health conditions for which there is reliable evidence that homeopathy is effective.
As I said, this conclusion does not come as a surprise. This research is the latest in a long line of reviews of the evidence for homeopathy that drew essentially the same finding:
A 2002 systematic review of systematic reviews of homeopathy published in the British Journal of Clinical Pharmacology concluded that:
the hypothesis that any given homeopathic remedy leads to clinical effects that are relevantly different from placebo or superior to other control interventions for any medical condition, is not supported by evidence from systematic reviews. Until more compelling results are available, homeopathy cannot be viewed as an evidence-based form of therapy.
A 2010 systematic review of systematic reviews of homeopathy published in the Medical Journal of Australia concluded:
The findings of currently available Cochrane reviews of studies of homeopathy do not show that homeopathic medicines have effects beyond placebo.
A 2010 report from the UK House of Commons concluded:
homeopathy is a placebo treatment.
In 2013, the NHMRC published a report based on their research that found:
There is a paucity of good-quality studies of sufficient size that examine the effectiveness of homeopathy as a treatment for any clinical condition in humans. The available evidence is not compelling and fails to demonstrate that homeopathy is an effective treatment for any of the reported clinical conditions in humans.
I could go on, but I hope by now you get the idea.
New Zealand pharmacists need to respond to the NHMRC’s research. And if they mean to practice responsibly and ethically, that response should be to immediately stop all promotion and sale of homeopathic products. The ethical standard to which they should be held is clear, and it is not consistent with promoting or supplying homeopathic products.
Last year, I complained to the Advertising Standards Authority under the auspices of the Society for Science Based Healthcare about a homeopathic product for preventing jet lag (No-Jet-Lag) that was advertised in Parnell Pharmacy. The pharmacy responded by removing the advertisement, and agreeing to stop selling the product if it was found that the claims were not supported by credible evidence, and my complaint was upheld. Unsurprisingly, my complaint was upheld when the ASA decided claims such as “it really works” were not supported by credible evidence. However, despite Parnell Pharmacy’s example, many New Zealand pharmacies still sell this exact product.
The NHMRC’s report represents the same finding, but on a larger scale. New Zealand pharmacists who promote and sell homeopathic products should follow the responsible example of Parnell Pharmacy, and remove homeopathic products from their shelves.
