What does 'prn' stand for in medication administration?

The abbreviation 'prn' stands for "as needed" in medication administration. This term is used when a medication is to be given only when the patient requires it, rather than on a scheduled basis. For example, a medication prescribed for pain relief may be taken prn, meaning the patient can take it when they feel pain, rather than at regular intervals. This allows for flexibility and ensures that the patient receives the medication in a manner that best meets their individual needs without unnecessary dosing when it is not required. Understanding these terms is crucial in ensuring proper medication management and adherence to healthcare protocols.
