In prescription terms, what does the abbreviation 'PRN' stand for?

The abbreviation 'PRN' stands for "as needed" in prescription terminology. This means that a medication is to be taken only when required rather than on a regular schedule. It's commonly used for medications that provide symptomatic relief but are not necessary to take at regular intervals, such as pain relievers or anti-anxiety medications.

Understanding this term is essential for both healthcare providers and patients to ensure that medications are used effectively and safely, allowing for flexibility in treatment based on the patient's current condition. It indicates a patient-centered approach, where the medication usage is tailored according to the individual's needs rather than a fixed schedule.
