Primum Non Nocere

Meaning

Primum Non Nocere is a foundational ethical and clinical principle in medicine, a Latin phrase meaning “First, do no harm.” This dictum mandates that all clinical decisions, diagnostic procedures, and therapeutic interventions must prioritize the patient’s safety and well-being, ensuring that the potential risks of treatment do not outweigh the expected benefits. In the context of hormonal health, this principle guides the conservative and judicious use of powerful agents like hormone replacement therapy, emphasizing the lowest effective dose and careful monitoring to mitigate adverse effects.
