A negative placebo effect, which may occur when patients in a clinical trial of a drug therapy recognise (or think they recognise) that they are getting a placebo—i.e., not receiving therapy—and fare worse due to the effect of negative suggestibility.

In a placebo response, trial participants improve when administered an inert substance; in a nocebo response, their symptoms get worse. More broadly, just as the placebo effect is the brain’s response the positive psychosocial context in which treatment occurs, the nocebo effect is the brain’s response to negative psychosocial context. Similar to the placebo response, nocebo and lessebo effects alter clinical trial outcomes and impact conclusions.

Neurology 88 June 6, 2017 7 In the narrowest sense, a nocebo response occurs when a drug-trial subject's symptoms are worsened by the administration of an inert, sham, or dummy treatment, called a placebo. According to current pharmacological knowledge and the current understanding of cause and effect , a placebo contains no chemical (or any other agent) that could possibly cause any of the observed worsening in the subject's … Placebo and Nocebo Effects Placebo and nocebo effects (effects of patients’ positive and negative expectations) are powerful and pervasive in clinical practice. Neurobiologic mechanisms Possible nocebo effect of 8% pain increase was found for intra‐articular injection of Ultracain. Conclusions. Based on the available data, the placebo response could play a major effect on TMD pain management and may be responsible from 10% to 75% of pain relief.

By definition (Evers et al., 2018), placebo responses refer to the (averaged) symptom response of a group of patients receiving a placebo during a randomized, placebo-controlled trial, e.g., of drugs. In contrast, the placebo effects refer to the individual change in symptoms that can be attributed to a known mechanism eliciting this change. Placebo response can be defined as any therapeutic change on placebo, while the nocebo response is any ill effect during placebo exposure. Several meta-analytic approaches have investigated the extent of placebo response in randomized, placebo-controlled, clinical trials of focal epilepsies. In a placebo response, trial participants improve when administered an inert substance; in a nocebo response, their symptoms get worse.
