Undisclosed Placebo Trials in Clinical Practice: Undercover Beneficence or Unwarranted Deception?

A placebo is an intervention that is believed to lack specific pharmacological or physiological efficacy for a patient's condition. While placebo-controlled trials are considered the gold standard when it comes to researching and testing new pharmacological treatments, the use of placebos in clinical practice is more controversial. The focus of this case study is an undisclosed placebo trial used as an attempt to diagnose a patient's complex and unusual symptomology. In this case, the placebo was used not just as a treatment, but as a diagnostic intervention in order to determine the best course of treatment for a patient. Could the deceptive use of a placebo be justified in clinical practice on the grounds of beneficence?
