What does the term PRN refer to in a medical context?

The term PRN in a medical context stands for "as needed," which indicates that a medication or treatment should be administered only when necessary rather than on a fixed schedule. This approach allows for more flexible and responsive patient care, tailoring interventions to the patient's individual needs and circumstances. For example, pain relief medications are often prescribed on a PRN basis, allowing patients to take them when they feel discomfort rather than at regular intervals. Understanding this term is crucial in both clinical settings and patient education to ensure appropriate use of medications and interventions.
