PRN medication
Also written as: PRN — pro re nata
Medication ordered to be given as needed based on specific symptoms or circumstances, rather than on a regular schedule.
Full Definition
PRN (pro re nata) medications are drugs prescribed to be administered as needed based on the patient's symptoms, condition, or specific circumstances, rather than on a fixed dosing schedule. In psychiatric settings, PRN medications are commonly used for managing acute agitation, anxiety, insomnia, or breakthrough symptoms. These orders must include specific parameters for administration, such as the indication for use, maximum frequency, and any precautions. Proper documentation of PRN medication administration, including the rationale for giving the medication and the patient's response, is essential for quality care and regulatory compliance.
Usage
Usage note: Always capitalize PRN; Latin abbreviation meaning 'as needed' or 'as circumstances require.'
