Full Definition

PRN (pro re nata) medication refers to drugs prescribed to be administered as needed, rather than on a regular schedule, based on specific clinical circumstances or symptom presentation. In psychiatric settings, PRN medications are commonly used for managing acute agitation, anxiety, insomnia, or breakthrough symptoms. Common PRN psychiatric medications include benzodiazepines for anxiety, antipsychotics for agitation, and sleep aids for insomnia. The use of PRN medications requires clear parameters specifying when to administer, maximum dosages, and frequency limitations. Documentation must include the indication for administration, patient response, and ongoing assessment of effectiveness and side effects.

Usage

Usage note: Always capitalize PRN. Include specific parameters and indications in orders.
