When is placebo use considered ethical in clinical trials?

Ethical placebo use rests on risk and necessity. It is appropriate when there is no proven effective therapy for the condition, or when adding a placebo is scientifically justified and would not expose participants to unacceptable risk. In these situations a placebo helps determine whether the new intervention has benefits beyond placebo without denying participants effective proven care. When there is an established effective treatment, using a placebo would withhold that care and is generally unethical; in such cases an active comparator or standard therapy should be used. Placebo use should not be based on patient preference alone, and it is not never allowed—there are valid, ethically approved scenarios that require safeguards like informed consent and independent oversight.
