Placebo and nocebo studies have evolved from predominantly methodological research into a far-reaching interdisciplinary field that is unravelling the neurobiological, behavioural and clinical underpinnings of these phenomena in a broad variety of medical conditions. As a consequence, there is an increasing demand from health professionals to develop expert recommendations about evidence-based and ethical use of placebo and nocebo effects for clinical practice.engDrug-related side effects and adverse reactionsHumansPhysician-patient relationsConsensusEvidence-based practiceNocebo effectPlacebo effectImplications of placebo and nocebo effects for clinical practice: Expert consensusjournal article10.1159/000490354
