15 Nonmaleficence Examples

nonmaleficence examples and definition, explained below

Nonmaleficence is a key principle in bioethics that underlines the obligation not to inflict harm intentionally.

It directly translates from Latin to “do no harm,” getting its roots from the Hippocratic Oath traditionally taken by physicians.

Though its origin is in the medical field, nonmaleficence is also an important standard in various contexts, extending to fields such as law, business, and technology.

This principle recognizes that harms are an inescapable part of human life, and it places an ethical duty on professionals to minimize such harms.

chrisNonmaleficence vs Beneficence: Nonmaleficence refers to the ethical duty of doing no harm. Beneficence, on the other hand, refers to the ethical duty of doing something to prevent harm. For instance, a doctor upholding the principle of beneficence would actively contribute to the patient’s fight against illness, striving towards recovery and improved wellbeing, not just harm prevention. The terms do overlap at times and many of these examples could also be examples of beneficence.


1. Medicine Prescription

Profession: Pharmacy
Risk: Harm to Patient

A pharmacist opting not to fill a prescription that could harm a patient acknowledges the principle of nonmaleficence. This may occur when a patient presents a prescription for a medication that conflicts adversely with another drug the patient is taking. By refusing to fill the prescription, the pharmacist acts to prevent potential harm. Instead, they would likely recommend the patient to consult the prescribing physician for a safer alternative.

Profession: Mental Health Counselling
Risk: Emotional Distress

A mental health counselor not probing into a touchy subject that could trigger emotional distress for their client is a form of nonmaleficence.
