When should PRN medications be administered at the discretion of a caregiver?

PRN medications, which stand for "pro re nata" (as needed), should be administered when there is observable behavior that indicates a need for the medication, such as extreme itching. This approach is essential because PRN medications are specifically designed to be taken only when there is a clear indication that the individual requires them.

For instance, if a person is experiencing severe itching, it is a clear signal that they may benefit from an antihistamine or other medication intended to alleviate that specific symptom. The caregiver uses their training and judgment to evaluate the client's condition and determine if the symptoms warrant the administration of the PRN medication.

Administering PRN medications solely when the client requests them can be problematic, as some individuals might not communicate their need effectively or may not realize when they should ask for help. Giving PRN medications only during scheduled medication times does not align with the purpose of these medications, which is to address symptoms as they arise rather than being confined to a fixed schedule. Finally, administering medications only when they are due according to the Medication Administration Record (MAR) ignores the individualized nature of PRN medication needs, which are dictated by the patient’s immediate condition rather than a set timetable.
