What does the abbreviation "PRN" stand for in medical terminology?

The abbreviation "PRN" stands for "as needed" in medical terminology. This term is commonly used in prescriptions to indicate that a medication should be taken only when required, rather than on a regular schedule. For example, a doctor might prescribe pain relievers to be taken PRN, which means the patient should take the medication only when they experience pain, rather than taking it at set times throughout the day. This flexibility allows for individualized patient care, addressing specific needs and symptoms as they arise.

The other options do not accurately represent the meaning of PRN. "Prescription Refills Necessary" would imply a routine requirement for medication, which does not align with the concept of "as needed." "Patient Receives Notice" does not pertain to medication administration or usage. Lastly, "Prior Authorization Required" relates to insurance processes rather than the administration of medications. Understanding the term PRN is essential for accurately interpreting medical instructions and ensuring appropriate patient care.
