Pharmacists Don’t Want to Sell Unproven Products

Pharmacists Don’t Want to Sell Unproven Products

The Pharmaceutical Society doesn’t think pharmacists should be able to sell healthcare products with no evidence of efficacy.

Last week I wrote about the Pharmacy Council’s proposal to change their Code of Ethics, and summarised the submissions that I was aware of. One important organisation that was missing from that roundup is the Pharmaceutical Society.

The Pharmaceutical Society is a professional association representing New Zealand pharmacists. Given their important position in the pharmacy industry, I think their submission might arguably be the most important. Earlier this week I spoke with Bob Buckham, Chief Pharmacist Advisor at the Pharmaceutical Society, about their submission on the Pharmacy Council’s proposal.

The Pharmaceutical Society does not support the proposed change. Coming from the perspective of pharmacists, their submission also raised two important points around this issue:

  • Pharmacists need clarity: what behaviour is consistent with the Code of Ethics, and what is not?
  • The Code of Ethics is important and cannot be ignored. The Pharmacy Council must be willing to provide guidance and to enforce the code.

The reason why the Pharmaceutical Society does not support this change is similar to the reasons given by other organisations, in that it would implement a double standard:

The Society does not support the proposed supplementary wording in obligation 6.9 as the split wording in the two parts separates the therapy terms “medicine or herbal remedy” in 6.9a from “complementary therapy or other healthcare product” in 6.9b. The result is that the subsequent obligation attached to those therapies does not apply to the other.

To clarify further, “credible evidence of efficacy” is only required when supplying or promoting a “medicine or herbal remedy” (Obligation 6.9a) and “no reason to doubt… quality or safety and when sufficient information about the product can be provided” only applies to “any complementary therapy or other healthcare product.

The Society considers that the obligations of “credible evidence of efficacy” and no reason “to doubt… quality or safety” should apply to the supply or promotion of all therapies and products – ie. any medicine, herbal remedy AND any complementary therapy or other healthcare product.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

Like other submissions, the Pharmaceutical Society does support the addition of a new clause about providing sufficient information for patients to make informed choices. However, they also made a similar suggestion to one in the Society for Science Based Healthcare’s submission in that the wording of this clause should be strengthened:

The Society also considers that “sufficient information about the product” must be provided in order for purchasers to make an informed choice with respect to efficacy of that product and the risks and benefits of that against other treatment options.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

Aside from their comments on the new proposed wording, the Pharmaceutical Society raised concerns about the application of this section of the Code of Ethics. Part of their submission focussed on pharmacists’ responsibility to comply with the Code of Ethics:

Pharmacists must comply with the Code of Ethics
The Council have stated that it is not the purpose of the Code, or the Council, to endorse or prohibit the supply of any particularly complementary and/or alternative medicine, product, or practice. However, as the responsible authority for pharmacy under the Health Practitioners Competence Assurance Act 2003, standards of ethical conduct set by the Council must be observed by pharmacists. Indeed, in the Code of Ethics the Council requires that pharmacists must comply with “all the implied requirements of ethical practice” within the Code.

The Medicines Regulations 1984 (in Schedule 2 related to applications for a licence to operate a pharmacy) also refers to how pharmacists being employed or engaged in duties in a pharmacy are

not requested or required to act in a way that is inconsistent with the applicable professional or ethical standards of the pharmacy practice

Therefore, the obligations within the Code of Ethics must be interpreted clearly so that pharmacists have a clear understanding of what is considered ethical practice, but also so that the Council can investigate and act upon breaches of the Code.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

This call for clarity has been a common theme among submissions. Both the NZ Skeptics’ submission and Dr Ben Albert’s submission called for guidelines on product categories that should not be sold in pharmacies due to a lack of evidence. Also, when the Society for Science Based Healthcare complained to the Pharmacy Council last year, one of the recommendations made was to for the Pharmacy Council provide guidance on this issue:

As a result of this complaint, we want pharmacists to have the opportunity to do the right thing and fulfill their ethical obligations. In order to achieve this, we suggest that the Pharmacy Council consider the following courses of action:

  1. To assist pharmacies in evaluating whether or not a healthcare product is supported by credible evidence of efficacy, the Pharmacy Council should develop and publish guidelines regarding what constitutes credible evidence of efficacy. This need not be a strict requirement so much as a useful guide that pharmacists can use to establish a consistent minimum standard of evidence.

NaturoPharm Wartoff Complaint (Society for Science Based Healthcare)

If it’s unclear where the line is drawn with regard to “credible evidence of efficacy”, it makes it more difficult for pharmacists to practice ethically. The Pharmaceutical Society’s submission raises questions about where this line might be drawn regarding alternative healthcare products, and talks about how the Code will be applied in practice:

Definition and interpretation of obligations
The wording of the proposed obligations 6.9a and 6.9b make reference to “credible evidence of efficacy” and “quality and safety”. Therefore, if presented with a complaint against a pharmacist claimed to be in breach of the obligations within the Code of Ethics, the Council is expected to determine what is “credible evidence of efficacy” and/or “quality or safety”.

The Society recognises that the application of a principles-based Code of Ethics to individual scenarios or circumstances is open to interpretation and challenge. Such scenarios are often not “black and white”, but “shades of grey” where a group of peers may have differing opinions to the acceptability or otherwise of a particular practice. It is expected that such “shades of grey” will always exist in pharmacy practice, as indeed it does in medicine and other areas of professional practice. However where a particular practice is determined to be unethical or unacceptably, this must be made clear. This is a difficulty faced when considering the evidence and use of complementary treatments against regulated medicines.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

The submission goes on to compare “natural” or herbal healthcare products with homeopathic products, in terms of plausibility:

Complementary/alternative medicine: natural/herbal remedies
The Society recognises the history of pharmaceuticals, and indeed of the pharmacy profession, where the first “medicines” were derived from natural products. Many of these have been purified, refined and further manipulated in the development of modern day pharmaceutics. Much of modern pharmaceutical research continues to analyse the therapeutic potential of compounds found naturally occurring substances derived from flora and fauna. We recognise how the levels of evidence of the therapeutic benefits (or otherwise) of natural products can vary markedly, but understand the science behind their potential mechanisms of action has the same pharmacological basis and pharmaceuticals.

Homeopathy
We note the Council’s own ‘Complementary and alternative medicines – best practice guidance for pharmacists’ document makes reference to the Natural Health and Supplementary Products Bill which states:

currently there is no accepted scientific evidence for the effectiveness of homeopathy and therefore that health benefit claims should not be made for homeopathic products

This aligns with further documents and statements issued internationally, including the Australian National Health and Medical Research Council (NHMRC)(1), the Cochrane Library and others have noted homeopathic products show no effects beyond placebo. A large number of government committees, professional pharmacy and medical organisations internationally have issued statements reinforcing this lack of effectiveness of homeopathy in treating health conditions. The Pharmaceutical Society of New Zealand does not at this time have a position statement on complementary medicines or homeopathy.

Homeopathy is not herbalism, and homeopathic science is not consistent with currently accepted medical and pharmacological science. Some pharmacists, and indeed other health professions, have argued for the role of homeopathy as a valid form of treatment to meed patient demand, while acknowledging any “benefit” is achieved through a placebo effect, while not necessarily agreeing with the purported science behind homeopathic practice.

The question for the Council must then be whether it is considered ethical practice for pharmacists to charge a fee for products for which there is no accepted scientific evidence for effectiveness; OR for which they acknowledge a lack of evidence yet sell for the purposes of providing a placebo effect.

Canberra: National Health and Medical Research Council; 2015. Available from: https://www.nhmrc.gov.au/guidelines-publications/cam02

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

The Pharmaceutical Society also noted something that was raised in a few other submissions; when pharmacies sell ineffective products they lend them the credibility of their profession, which can inadvertently lead to patients being misled about their efficacy.

While we again note that the Council have expressed that it’s not their purpose or the purpose of the Code of Ethics to “endorse any particular complementary or alternative medicine or practice”, in setting the requirements for pharmacists to conform with obligation 6.9 (or 6.9a and 6.9b), the Council must determine whether the practice of homeopathy is consistent with the Code. Particularly when having homeopathic products available alongside pharmaceutical medicines, or indeed herbal/complementary medicines with their varied levels of evidence, potentially implies clinical benefit by association and provision through a respected and regulated health professional.

Submission to the Pharmacy Council of New Zealand (Pharmaceutical Society of New Zealand)

I’ve not yet been made aware of any other submissions that have been made to the Pharmacy Council, but I imagine a number of individuals at least will have made submissions that have not been publicised. As it stands though, the Pharmacy Council’s proposal seems to have strong opposition from all sides, with the only significant support I have seen so far coming from the Pharmacy Guild, who represent only those pharmacists who own their own pharmacies.

It seems no group other than pharmacy owners wants to keep the status quo of pharmacies selling ineffective products without consequences.

Pharmacy Council’s Code of Ethics Proposal: Submissions Roundup

Pharmacy Council’s Code of Ethics Proposal: Submissions Roundup

The Pharmacy Council has proposed a change to their code of ethics, here’s everything you need to know.

EDIT 22/10/2015: When this article was published it didn’t include details of the Pharmaceutical Society’s submission. Since then, I have spoken with their Chief Pharmacist Advisor, Bob Buckham, about their submission. For more details, see my article summarising it: Pharmacists Don’t Want to Sell Unproven Products

The Pharmacy Council is the statutory body responsible for setting standards of conduct and competence of pharmacists in New Zealand. They have a code of ethics, the Safe Effective Pharmacy Practice Code of Ethics 2011, which currently includes a section that requires pharmacists must:

6.9
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.

Safe Effective Pharmacy Practice Code of Ethics 2011 (Pharmacy Council)

In August, the Pharmacy Council proposed to change this section of the code of ethics. The first part of the proposed change is to remove the requirement for complementary therapies and other healthcare products to be supported by credible evidence of efficacy before they can be promoted or supplied in a pharmacy. The other part is to add a requirement that purchasers must be given enough information about these products to make an informed choice:

6.9a
Only supply or promote any medicine or herbal remedy where there is no reason to doubt its quality or safety and when there is credible evidence of efficacy.
6.9b
Only supply any complementary therapy or other healthcare product where there is no reason to doubt its quality or safety and when sufficient information about the product can be provided in order for the purchaser to make an informed choice with regard to the risks and benefits of all the available treatment options.

Proposed supplementary wording to clause 6.9 of the Code of Ethics 2011 (Pharmacy Council)

As part of this proposal, the Pharmacy Council called for submissions from stakeholders. In my last article on this topic, I discussed the submission from the Society for Science Based Healthcare, of which I am a co-founder. Although the extended deadline for submissions passed last Friday, various other groups have made their views on this proposal clear and made their own submissions.


The Society for Science Based Healthcare

The Society for Science Based Healthcare is a group of consumer advocates, scientists, and medical professionals. I am one of its co-founders. The submission from the Society for Science Based Healthcare proposed a modified version of the new wording:

6.9a
Only supply any medicine or herbal remedy where there is credible evidence of efficacy.
6.9b
Only promote any complementary therapy or other healthcare product where there is credible evidence of efficacy.
6.9c
Only supply or promote any medicine, herbal remedy, complementary therapy or other healthcare product where there is no reason to doubt its quality or safety, when there is not credible evidence to suggest that the product lacks efficacy.
6.9d
Provide sufficient information about any medicine, herbal remedy, complementary therapy or other healthcare product product in order for the purchaser to make an informed choice with regard to the risks and benefits of all the available treatment options.

Pharmacy Council Code of Ethics Proposal (Society for Science Based Healthcare)

After lodging a complaint last year with the Pharmacy Council regarding an incident in which a patient was misled by an Auckland pharmacy that recommended and sold them a homeopathic product, both the Pharmacy Council and the Health and Disability Commissioner refused to enforce the code by telling the pharmacy not to promote or sell the homeopathic product, despite the fact that it was not supported by any credible evidence of efficacy.

In principle, the society would oppose the change. However, having have found that the existing section of the code is disregarded rather than enforced, the society decided it was best to try to turn the code into something the Pharmacy Council might be willing to enforce that could still offer protection to patients.

It is currently widespread practice for New Zealand pharmacies to supply and promote healthcare products which are not supported by credible evidence of efficacy, such as homeopathic products.

Pharmacy Council Code of Ethics Proposal (Society for Science Based Healthcare)

This view that the current code of ethics is commonly disregarded has been shared among many of the other submissions that have been made public, and appears to be supported by a statement made by the Pharmacy Council chairman Dr Andrew Bary in a recent article on Stuff.co.nz:

But Pharmacy Council chairman Dr Andrew Bary said the rules as they stood were “unworkable” and many pharmacists, including himself, were already selling complementary medicines, even if they didn’t believe their claims.

Doctors and pharmacists clash over complimentary medicines (Stuff.co.nz)

The Society for Science Based Healthcare’s submission also argued that there are both potential risks and potential benefits to these products being sold in pharmacies. The proposed new wording is intended to provide the best risk/benefit profile for patients.

On the one hand, if these products are available in a pharmacy consumers will be more likely to visit a pharmacy to purchase them. This can put them in a position where a pharmacist is able to provide them with evidence-based advice, so they can make an informed decision on purchasing the best product for whatever problem they are experiencing. If the product were not available in a pharmacy, they may instead seek it from a source which would not provide them with this information, or which may misinform them.

On the other hand, when a product is available in pharmacies it is likely to lead consumers to believe that it is an effective, evidence-based product. This is often used as a selling point by products which are not supported by evidence. For example, the homeopathic product No-Jet-Lag advertises itself as being available at “Most chemists nationwide“. In this way, pharmacists stocking products without credible evidence of efficacy can also contribute to an increase in consumer demand for them. For all intents and purposes, supplying a product in a pharmacy is also a form of promotion.

Pharmacy Council Code of Ethics Proposal (Society for Science Based Healthcare)

When it was submitted this submission had a list of 36 supporters, 24 of whom are healthcare professionals or PhD scientists


The NZ Skeptics

The NZ Skeptics’ submission opposed the change. It also proposed that the Pharmacy Council maintain a list of products or product categories that are not supported by credible evidence of efficacy, to make it easier for pharmacists to determine which products could or could not be sold in pharmacies. The motivation for this recommendation is similar to one made in the Society for Science Based Healthcare’s complaint last year:

As a result of this complaint, we want pharmacists to have the opportunity to do the right thing and fulfill their ethical obligations. In order to achieve this, we suggest that the Pharmacy Council consider the following courses of action:

  1. To assist pharmacies in evaluating whether or not a healthcare product is supported by credible evidence of efficacy, the Pharmacy Council should develop and publish guidelines regarding what constitutes credible evidence of efficacy. This need not be a strict requirement so much as a useful guide that pharmacists can use to establish a consistent minimum standard of evidence.

NaturoPharm Wartoff Complaint (Society for Science Based Healthcare)

To inform their submission, the NZ Skeptics conducted a “secret shopper” exercise with their members to discover what actually happens when consumers talked to pharmacy staff about homeopathy.

We found that around half of the pharmacies visited had staff that were willing to promote or supply homeopathic products without adequately explaining the current lack of evidence.

It seems that some pharmacies did not stock homeopathy, but a significant number of others did have homeopathic products on their shelves and in most of these pharmacies staff were willing to offer homeopathy as a viable treatment, with no information offered about a lack of efficacy.

With the code being an important patient protection mechanism, we’re disappointed to see it so readily disregarded.

Submission to the Pharmacy Council’s 2015 Code of Ethics Consultation (NZ Skeptics)

The NZ Skeptics have made these reports available on their website: Pharmacy Homeopathy Reports. As well as this, they conducted a non-exhaustive search for New Zealand pharmacies promoting homeopathic products online, and made the results of this available too: Pharmacies Promoting Homeopathy.

One argument that is used to support pharmacies selling products with no credible evidence of efficacy is that, if pharmacists were prevented from selling these products, then patients’ freedom of choice would be infringed. This argument has been made, for example, by Pharmacy Council chairman Dr Andrew Bary when he was interviewed on Radio New Zealand about this proposed change:

You know, I think we need to respect the wish of the consumer from time to time, so you know, individuals have their own cultural and traditional beliefs around certain alternative and complementary therapies… So I think that the key thing is that we are setting out that we think pharmacists should be informed about the efficacy of the evidence for each individual product when they are promoting and making recommendations to people. But at the same time, we need to put the person at the centre, the consumer, and respect their wishes and desires.

Pharmacy Council moves to change code of ethics over homeopathy (Radio New Zealand)

The argument has also been put forth by pharmacists that sell these products in their pharmacies:

“Many patients believe homeopathy has been of benefit and they should be given the freedom to choose it if they want, [Lincoln Mall Pharmacy owner pharmacist Caleb Townsend] says.”

Pharmacists support patient choice with homeopathy (Pharmacy Today)

It may be worth noting that Lincoln Mall Pharmacy is one of the ones on the NZ Skeptics’ list of pharmacies promoting homeopathy online, and the Pharmacy Today article notes they have “qualified homeopaths onsite”. An Advertising Standards Authority complaint laid by Society for Science Based Healthcare member Simon Clark was settled in June when the pharmacy opted to remove claims that homeopathic products can “treat a wide range of illnesses and concerns” from an online listing.


Ben Albert et al.

Dr Ben Albert is a paediatric endocrinologist who researched fish oil for his PhD, which made headlines earlier this year after his research was published in the Nature journal Scientific Reports. Along with five other doctors, he has written a submission to the Pharmacy Council opposing the change.

Despite coming from a group of individuals rather than a professional society, the submission boasts the impressive support of 180 medical doctors, predominantly senior consultants, representing all medical specialties. It also has the support of the NZ Society of Paediatric Surgeons and the NZ Resident Doctors Association, which represents over 90% of the resident medical officer workforce in New Zealand. Its authors are:

  1. Dr Benjamin B. Albert FRACP, Paediatric Endocrinologist and Clinical Research Fellow. Liggins Institute, University of Auckland.
  2. Professor Wayne S. Cutfield MD FRACP. Professor of Paediatric Endocrinology, and Director of A Better Start National Science Challenge, Liggins Institute, University of Auckland. Past president, Australasian Paediatric Endocrinology Group. Past president, Asia Pacific Paediatric Endocrine Society.
  3. Professor Paul L. Hofman FRACP. Professor of Paediatric Endocrinology, Director of the Maurice and Nessie Paykel Clinical Research Unit, Liggins Institute, University of Auckland. President Asia Pacific Endocrine Society. Past president Australasian Paediatric Endocrinology Group.
  4. Professor Alistair J. Gunn PhD FRACP. Professor of Physiology and Paediatrics, and Head of Department of Physiology, University of Auckland. Paediatric Endocrinologist.
  5. Associate Professor Timothy Kenealy PhD FRANZCGP, Professor of Integrated Care, University of Auckland. General Practitioner.
  6. Dr Olivia J. Albert FANZCA. Anaesthetist, Royal Hospital for Women, Sydney, Australia.

The specific recommendations made in their submission are:

  • Reject the proposed change, or reinsert the requirement for “credible evidence of efficacy” in to clause 6.9b. We suggest this wording.

    • where there is no credible evidence to suggest a specific complementary and/or alternative medicine/product is effective, or the proposed effect of the product is scientifically implausible pharmacists should not promote or recommend its use
  • Current ethical standards should be enforced
  • Treatments and products that do not have “credible evidence of efficacy” such as homeopathic remedies, ear candles and magnet based therapies should be listed by the PCNZ, with the intention that they are not sold in pharmacies.

Submission to the Pharmacy Council of New Zealand (Ben Albert et al.)

The last recommendation echoes that of the NZ Skeptics, aiming to simplify things for pharmacists by providing a list of products or product categories which clearly are not supported by credible evidence of efficacy.

The rationale for their opposition to the change is laid out clearly and concisely in the submission:

The suggested change is in opposition to the general principles of the code, and the expectations of the public and other members of the multidisciplinary science based healthcare team.

This change would make it permissible within the ethical code for pharmacists to promote and sell products that are unproven and even scientifically implausible. We believe that this is harmful and wrong.

the current code should be enforced, not amended.

Submission to the Pharmacy Council of New Zealand (Ben Albert et al.)

They raise another counterargument to the “freedom of choice” argument, noting that pharmacists should be wary of their conflict of interest between advising against patients purchasing products that aren’t supported by evidence and selling more products to generate more profit for the pharmacy:

pharmacists (like many health providers) have a conflict of interest when they sell and give advice about health products from which they make profit. There is evidence that financial pressures do impact the clinical decisions of pharmacists1. One of the reasons that a code of ethics is important is because it provides guidance where the interests of pharmacists and patients differ.

Submission to the Pharmacy Council of New Zealand (Ben Albert et al.)

They also raise the issue that products sold in pharmacies are likely to be seen as effective by the public, which can lead to harm when they are sold in pharmacies:

Many patients will assume that the pharmacist endorses the health products sold in the pharmacy as scientifically supported. But many pharmacists sell products that are known to be ineffective, such as homeopathic remedies3 or potentially harmful, such as ear candles4. Selling such products conflicts with the principles of the current code5 as it reduces patient autonomy. The patient that wrongly assumes that a health product is scientifically supported is ill-prepared to make an informed decision.

Submission to the Pharmacy Council of New Zealand (Ben Albert et al.)

Although this submission has not been made public, it shares much in common with a letter to the editor from the same authors that was published today in the New Zealand Medical Journal.

I spoke with Dr Albert to ask what motivated him to take action on the Pharmacy Council’s proposal, here’s what he had to say:

For years it has bothered and surprised me that products that are entirely implausible such as magnets and homeopathic remedies, and harmful products such as ear candles are sold in pharmacies. When scientifically trained and trusted health professionals promote and sell such treatments they betray the trust of the public who will quite reasonably assume such products are endorsed by the pharmacist and supported by scientific evidence. The current PCNZ code of ethics indicates that it is unethical and unprofessional for pharmacists to sell these products. The right course of action is to stop selling them. To instead change the code to redefine ethical behaviour appears cynical and makes the sale of unsupported or harmful treatments no less wrong.

Dr Ben Albert


The New Zealand Medical Association

The New Zealand Medical Association is New Zealand’s largest medical organisation, representing over 5,500 medical professionals. The New Zealand Medical Association’s submission strongly opposes the change. They echo the views of other submissions that in the face of widespread behaviour at odds with the current code, the way forward should be change behaviour to match the code rather than to relax the code to permit existing behaviour:

The NZMA is strongly opposed to the above proposed change

We do not believe that pharmacists should be selling ‘treatments’ that are known to be ineffective or lack evidence of effectiveness. We contend that doing so is unethical. While this practice may be happening under the present Code, we believe that the PCNZ should be seeking ways to enforce the Code rather than amend it to accommodate this practice.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)

The NZMA acknowledged the trust placed in pharmacists by the public, and how this affects the way in which products sold in pharmacies are perceived:

It is our view that allowing pharmacists to sell ineffective therapies or products is contrary to the profession’s own aspirations, including of trustworthiness and professionalism. More broadly, it undermines the social contract between the public and the profession. The pharmacist is trusted by patients and other members of the health care team precisely because of their scientific training. The sale of products by pharmacists that knowingly do not work is inconsistent with the high trust health care professional the public expects and the profession requests.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)

The NZMA also deals with the “freedom of choice” argument in a similar way to the other submissions:

We understand that patient autonomy and freedom of choice are being advanced as the rationale for the proposed rewording to the Code. We believe these are spurious arguments on which to remove the requirement for “credible evidence of efficacy” for pharmacists to sell complementary therapies or other healthcare products. Freedom of choice should not transcend the health and well-being of the patient. Furthermore, such products are already available to people to purchase at other outlets, such as health food shops and supermarkets.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)

The NZMA raised some new concerns, regarding the potential impacts of the proposed change:

The proposal is of all the more concern given the current lack of regulation of complementary therapies in New Zealand.

We are also concerned at the impact of the proposal on equity. Patients that are least likely to consult a doctor could end up being even more likely to purchase costly ‘healthcare’ products from their pharmacy that do not work.

The proposal also undermines the wider health sector’s efforts to improve health literacy.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)

The NZMA’s final recommendation is for the requirement for credible evidence of efficacy to be kept and enforced, and until it is enforced for the newly proposed requirement for supplying sufficient information to make an informed choice to bridge the gap:

Ideally, we would like to see pharmacists end the sale of complementary therapies or other healthcare products for which there is no credible evidence of efficacy (ie, meet their obligations under the existing Code). Until such time, we would suggest the addition of a subclause to 6.9 which addresses the need to provide sufficient information for herbal remedy, complementary therapy or other healthcare product. Accordingly, we proposed the following wording:

6.9
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.
6.9a
When supplying a herbal remedy, complementary therapy or other healthcare product, sufficient information about the product must be provided in order for the purchaser to make an informed choice with regard to efficacy of the product and the risks and benefits of all available treatment options.

Submission to the Pharmacy Council of New Zealand (New Zealand Medical Association)


The Pharmacy Guild

The Pharmacy Guild represents pharmacy owners in New Zealand. The Pharmacy Guild’s submission supports the Pharmacy Council’s proposed change:

We support the Council’s intentions of the proposed changes to clause 6.9 of the Code of Ethics 2011 (the Code).

Consultation on the proposed wording to clause 6.9 of the Code of Ethics 2011 (Pharmacy Guild)

The primary motivation for this support seems to be a combination of the “freedom of choice” argument I described above, and the potential for benefit described in the Society for Science Based Healthcare’s submission:

We believe that if pharmacists were prevented from selling natural products then patients wanting these products would continue to source them from somewhere. We consider that it is far safer for consumers to approach pharmacists for advice and that they purchase supplies of complementary medicines from a pharmacy rather than over the internet for instance, where the quality and safety of a product cannot always be guaranteed.

Consultation on the proposed wording to clause 6.9 of the Code of Ethics 2011 (Pharmacy Guild)


As well as these submissions, I have been made aware of a few more, mainly submitted by individuals. Of those I am aware of, such as Edward Linney’s submission, they are predominantly opposed to the change for many of the reasons described in these submissions. I am aware of one instance of an ex-pharmacist who supports that change who is now a practising homeopath and, scarily, was previously employed by the Pharmacy Council as their Professional Standards Advisor even while they were practising as a homeopath. However I don’t know if they have made a submission.

I’m also aware that the Pharmaceutical Society has made a submission. Whereas the Pharmacy Council regulates pharmacists, the Pharmacy Guild and Pharmaceutical Society are membership organisations; the Guild represents pharmacy owners and the Society represents pharmacists in general. Although I have tried to get in touch with them, I haven’t seen the Pharmaceutical Society’s submission and can’t provide comment. I will update this article if that changes.

However, I am aware that the Pharmaceutical Society has close ties to the New Zealand Medical Association, even to the point where they have a joint agreement for members to abide by both organisations’ codes of ethics. So I expect that if they have made a submission it may be along similar lines to the NZMA’s submission.

If anyone knows of any more information that I’ve missed in this article, please leave a comment below.

Osmosis Skincare’s Drinkable Sunscreen Trial

If you haven’t already read my post about Osmosis Skincare’s Drinkable Sunscreen, you might want to do that before you read this one. A brief overview is that Osmosis Skincare claims drinking their “harmonized water” prevents sunburn. I complained to the Advertising Standards Authority that this claim wasn’t backed up by evidence and the complaint was upheld, now those products have been removed from their New Zealand website as a result.

In their response to this complaint (which you can read via the ASA’s website), Osmosis Skincare said that (emphasis mine):

This is a new type of technology being used in this way and Head office can reference the internal research they did showing the product to be effective, but their independent clinical trial isn’t until the 28th of June, whereby they will put 30 people outside for one hour in San Diego, CA at noon supervised by a plastic surgeon.

Osmosis Skincare NZ – Response to ASA complaint 14/287

When reading this, I noticed that the study design seemed to be lacking a control group (which prohibits randomisation and blinding) and that the sample size seemed very small. These are all properties of low-quality science, but with only this brief summary to go by I couldn’t draw in any firm conclusions. In any case, as they were making therapeutic claims without any evidence to back them up, the complaint was upheld.


A few days ago, the head office of Osmosis Skincare issued a press release regarding this “independent clinical trial”, which has now been completed. I have to say I wasn’t particularly surprised to read that the trial was actually not independent. The press release introduces it by saying:

Osmosis Pür Medical Skincare executed the [Harmonized Water UV Neutralizer] line’s first clinical trial on June 28, 2014.

Osmosis Skincare – First Drinkable Sunscreen Releases Clinical Trial Results

The press release also claimed that the trial was randomised (emphasis mine):

The randomized clinical trial was designed to evaluate a new technology…

Osmosis Skincare – First Drinkable Sunscreen Releases Clinical Trial Results

When a clinical trial is randomised, that means that participants are allocated into different groups in a way that is determined randomly. These different groups typically consist of an experimental group, which receives the treatment being tested, and a control group, which receives either a placebo or sham version of the treatment or the standard of care against which the experimental treatment is being compared. Randomly allocating participants into these groups helps avoid any systematic differences between the groups that could be a source of bias in the results.

Of course, this necessitates multiple groups for participants to be included in. With a sample size of 30, this means each group would only contain around 15 people. However, the press release isn’t done with its surprises yet:

24 patients ranging from 18 to 60 with various ethnic backgrounds and skin types were exposed to one hour of sun to one side of the body between noon and 1pm after ingesting 3ml Osmosis Harmonized Water UV Neutralizer

Osmosis Skincare – First Drinkable Sunscreen Releases Clinical Trial Results

The press release doesn’t mention 6 other participants in a control group, so it’s not clear yet if there was another (smaller) group that just isn’t mentioned here or if, for some reason, they went with 24 participants instead of the 30 they’d planned on using earlier.

The “Summary of Results” says that:

All 24 patients were evaluated before, and immediately after the exposure as well as the following morning. There was no evidence of sunburn on 16 patients, 5 had minor or partial sunburns and 3 had notable sunburns in the study.

This proves UV Neutralizer effectively limited the sun damage for a majority of the users that consumed it.

Hang on a minute, “proves”? I’m not sure how on Earth they’d expect to be able to honestly evaluate the effectiveness of their product without first establishing some baseline to use as a comparison. It reads as though they’ve assumed that, if their product didn’t work, then all participants would have received notable sunburns. If they want to gather evidence regarding the effectiveness of their product in an intellectually honest way, they’d need to either compare it to a placebo or to the standard treatment, so they can actually see if it cause different results than nothing or if it’s as good as the real deal.

Instead, though, we get quotes like this:

The definitive results from this trial prove that the scalar wave technology in Harmonized Water works.

The press release then provides links to the clinical trial and photos of participants.

If you click on those links, you’ll probably notice a couple of things right away. First, instead of being published in a peer-reviewed scientific journal, the link to the clinical trial takes you to a folder on “box.com”, a cloud storage website. Second, the PDF containing photos of participants only contains 16 participants, not the 24 we’re told participated in the trial. I’ve no idea why that is the case, or how they determined which 8 participants to exclude.

The paper, entitled “Evaluation of a Novel Form of Sun Protection”, seems laid out pretty much as one would expect from a real clinical trial, published in a peer-reviewed scientific journal. Its first author is Paul Ver Hoeve, the doctor that supervised the experiment, and the second author is Ben Johnson, the founder and CEO of Osmosis Skincare (although that conflict of interest isn’t stated in the paper itself). I’m really wondering why this was ever described as “independent”. Hopefully this was just a piece of honest confusion on the part of whoever was liaising with the ASA on behalf of Osmosis Skincare NZ.

Unsurprisingly, although the authors included 8 distinct references (out of 11 in total) for the claim that topical sunscreens can cause inflammation, this claim went unreferenced:

Upon ingestion of 2-3 ml of the [harmonized] water, the scalar waves reportedly work their way through the molecules of water in the body until they reach the water in the dermis. This process has been shown to take an hour on an empty stomach, 90 minutes if any food is present in the stomach.

The “Subjects and Methods” section starts with a very concerning sentence. As far as I can tell, this is the entire basis for describing the study as “randomized”:

In this study, 24 patients were randomly selected as test subjects with no consideration for their natural skin tone.

Paul Ver Hoeve, Ben Johnson – Evaluation of a Novel Form of Sun Protection

As I mentioned earlier, when a clinical trial is described as “randomised” that means participants are randomly allocated to different treatment groups. It absolutely does not mean “patients were randomly selected as test subjects”. I’m not sure what that even means. It sounds like it’s referring to their recruitment method, but no more detail is given so I can’t really tell what this is supposed to say about the study design.

In my opinion, using this as justification for describing this experiment as a “randomized clinical trial” is very misleading.

The report goes on to state that:

The decision was made to not do a double-blind test for this application because of the ethical implications of knowingly causing a sunburn in many people.

Paul Ver Hoeve, Ben Johnson – Evaluation of a Novel Form of Sun Protection

Despite this apparent ethical concern, I can see no indication of the trial being approved by an Institutional Review Board (IRB). I believe IRB approval is required of all human subject research in the USA that is publicly funded, but privately funded research like this doesn’t have the same requirement. I’m not sure how it would affect a trial’s chances of being published in a peer-reviewed journal, perhaps someone who knows more could weigh in via the comments.

Performing “a double-blind test” in this case would require giving some participants water then leaving them to burn in the sun for an hour, and they’re right to say that’s pretty obviously unethical. I think the fact that they realise this but it’s also what they did in their trial should have been a pretty big red flag that they could use some ethical oversight.

They also don’t mention what seems to me is obviously a more ethical and rigorous way to conduct the trial. Even if they didn’t manage blind the researchers, it would have been better for everyone if the experimental group were compared to a control group that had applied topical sunscreen instead. This would allow them to have a “randomized clinical trial” that is actually randomised, as well as giving them a baseline to compare their results to so they might have a chance to draw some useful conclusions.

The actual results of the experiment were that:

There was no evidence of a sunburn on 16 patients, 5 had minor or partial sunburns and 3 had significant sunburns in the study.

Now I don’t know about you, but 1/3 of participants getting sunburned doesn’t exactly sound like a rousing success to me. They went on to try to justify these failures by saying:

All of the patients who burned said they would not normally lay [sic] out in the sun for one hour. Many of them said they burn with the use of other sunscreens as well.

Paul Ver Hoeve, Ben Johnson – Evaluation of a Novel Form of Sun Protection

The report gives no indication that the other 16 participants were asked the same questions, so there’s no way of telling if this could have contributed to the results, let alone accounted for them. As far as I know, this hasn’t prompted Osmosis Skincare to put a warning label on their products that it’s not effective for people that don’t usually expose themselves to the sun very much. It also doesn’t stop the authors from putting the results down to these answers entirely:

While the results were not 100%, the authors believe this was due solely to the excessive amount of sun they received to their relatively virgin skin and their overall health.

This trial had a tiny sample size, and was uncontrolled (therefore also non-randomised and unblinded), as well as being industry-funded and co-authored by the founder of the company that makes and sells the product. And on top of all that it didn’t even seem to have had particularly positive results.

If there’s any conclusion that can be drawn from this study, it’s that Osmosis Skincare is willing to do bad science and use its mediocre results to promote their products. Considering they were already making the same therapeutic claims before this experiment, I can’t say I find that surprising.

If Osmosis Skincare NZ stands by this research, and considers it rigorous enough to justify the sort of claims they were previously making about these products without substantiation, then they should appeal the ASA’s decision to uphold a complaint against them. I’d certainly like to see them try.
