Researchers at several American institutions recently reported that half of 679 American doctors who had been surveyed said they regularly prescribed placebos to their patients. This news came as a shock to many people -- and raised serious ethical questions.

Everyone knows what placebos are -- sugar pills or dummy pills that masquerade as medication. But is it that simple?

Theres a lot more to the question than meets the eye, according to Richard L. Kradin, MD, one of the countrys foremost experts on the use of placebo treatments. To learn more, Bottom Line/Health recently spoke with him...

What exactly is a placebo? Its any type of therapeutic intervention -- for example, a fake or unproven medication, a sham surgical procedure or a talk with the doctor -- that, in and of itself, is judged to have no therapeutic capacity. When it works, the success is attributed to an activation of whats called the placebo response.

How is the placebo response believed to work? Before there were any scientific medical treatments, people got sick and got well. In species such as ours, some of these responses involve the bodys ability to soothe itself and to restore states of physical and mental well-being. This self-soothing process is key to the placebo response.

Certain memories are probably involved. For example, children are usually soothed by their parents. Their mothers kiss minor hurts to make them better. They are given pills and told the medicine will make them well. When adults are sick and receive care from someone whos supposed to help them, the situation can reawaken this capacity to be soothed. After a visit to the doctor, some people report that they feel better right away.

Can a person who has a serious illness be healed by the placebo response? There are people who appear to have been cured of cancer by what might be termed the placebo response. In one case, an experimental chemotherapy drug -- later shown to be inactive -- was highly effective in a patient as long as he believed it was capable of curing his cancer. But that scenario is quite rare.

Placebos seem best able to restore well-being when problems are minor, such as a headache or stomachache. Its important to remember that the placebo response isnt necessarily separate from real therapeutic responses brought about by effective treatment, but part of them. If you take a drug that works, the placebo response may make it work better. Many of the factors involved in the placebo response have been scientifically confirmed in a number of studies on the topic.

Do placebos do more for some people than for others? In most clinical trials, one-third of patients who receive a sugar pill feel better. But its hard to predict which people will respond positively to placebo treatment.

Trust and expectation increase the chance of a positive response. If you believe that a drug or treatment is likely to help you, the odds are that it will work as a placebo.

If the doctor or other caregiver conveys a sense of competence and authority, and the visit to the doctors office promotes relaxation and trust, these factors also seem to elicit the placebo response. The doctors ability to listen and make patients feel that theyre understood is important. If the doctor doesnt convey his/her own belief that the intervention will work, the chances are good that it wont work.

Can a placebo have harmful effects? Negative, or so-called nocebo, responses are quite common. For example, about 25% of participants in clinical trials report side effects after receiving a harmless pill. Similarly, a certain proportion of adverse reactions to prescribed medications are no doubt due to the nocebo response.

Here, too, expectation plays a role. Nocebo effects commonly occur after a patient reads the drug package insert that lists, often in alarming detail, a medications potential side effects. The health-care provider can elicit the nocebo response, too. People sometimes leave the office of a brusque, uncaring doctor feeling much worse, and getting little benefit from the medication the doctor prescribed. If a caregiver expresses too many doubts about the treatment, patients detect that as well.

Is it ethical for a doctor to prescribe a drug as a placebo without the patients consent? In many situations, with many types of people, conveying the entire truth, including doubts surrounding the treatment, may not be in the patients best interest in terms of therapeutic outcome. On the other hand, if a doctor is caught prescribing a placebo, he risks losing his credibility. Most placebos are prescribed unwittingly by doctors who prescribe a medication off-label -- for an unapproved use -- in the belief that it will help.

By the same token, when I talk in detail with a patient about a particular drugs potential side effects, as mandated by law, I can see fear well up in his face. Is that the role of a healer? Im not so sure.

Can medical consumers harness the power of their own placebo responses? Yes. In choosing a health professional, you should try to find someone you can trust and have confidence in. Dont go to anyone who doesnt evoke this trust. Its possible for a doctor to be brusque and still convey the confidence that a patient needs. Some people respond well to that kind of personality.

Know yourself. If you leave a treatment situation feeling doubtful and not reassured, youre probably in the wrong place.

How can you minimize nocebo effects? I suggest to my patients that they read the medication package insert only if they experience a side effect, to check whether it is a common one. I believe its better to stay modestly informed -- and to recognize and respect the expertise of the doctor or other health professional. Important: Any side effect that is not short-lived should be reported to your physician so that potentially serious adverse reactions are not missed.

You should be a working partner in your treatment and have some idea of whats going on. But when people start involving themselves in the fine details, it tends to have a disturbing effect on mind-body processes -- either resulting in a nocebo response or limiting the advantages of the placebo response.

Mmm. A bit unreliable to say the least. Seems to rely on hearsay at best. Reviews of 'placebo responses' don't support the notion as curing biomedical illness (where objective measurements are needed rather than self-report, which is subject to various confounders), and there are always other potential reasons for claims of placebo or nocebo 'effect'. Yet we see these articles with monotonous regularity : (

Yes, it all gets a bit tiring, doesn't it.

Belief in the power of the placebo/nocebo response has become almost a religion, and certainly a convenient 'explanation' of last resort by both clinicians and researchers. Pity the meta-analyses (from Cochrane, no less) find no evidence for a consistent, persistent, widespread, and substantial therapeutic response to placebo treatment. The best placebophiles can currently claim is that it seems to have a very modest effect on pain and nausea, and only when using patient self-reporting (ie problematic subjective measures).

Placebo interventions for all clinical conditions
Hrbjartsson A, Gtzsche PC.
Cochrane Database Syst Rev. 2010 Jan 20;(1):CD003974.
PubMed 20091554

AUTHORS' CONCLUSIONS: We did not find that placebo interventions have important clinical effects in general. However, in certain settings placebo interventions can influence patient-reported outcomes, especially pain and nausea, though it is difficult to distinguish patient-reported effects of placebo from biased reporting. The effect on pain varied, even among trials with low risk of bias, from negligible to clinically important. Variations in the effect of placebo were partly explained by variations in how trials were conducted and how patients were informed.

For the record, I do not dismiss the placebo response, which is almost certainly real. But I very seriously doubt its claimed explanatory and therapeutic powers.

I "like" how this question wasn't answered! I would think it would be illegal for someone to prescribe you a medicine, when it is really not medicine! LDN is taken "off-label", I don't see how this is a placebo? I thought a placebo was usually something like s a sugar pill? LDN is not sugar!
