Primum Non Nocere

Meaning

Primum Non Nocere, a foundational ethical axiom in medicine, translates directly from Latin as “First, do no harm.” This principle dictates that a clinician’s primary obligation is to prevent harm to the patient, ensuring that any intervention, diagnostic procedure, or therapeutic approach does not cause undue injury or adverse effects. It underscores a cautious, patient-centered approach to healthcare, prioritizing safety above all else.
