Quote from SusanNC. Butch, as Jennifer mentioned PRN are the Latin initials for the medical term meaning As Needed. If the Dr. gives an order for X-med q4h PRN - it simply means that you can give X to the patient every 4 hours as needed. If this is a pain med and the patient doesn't complain of pain - you don't need to give it (because it's not needed). Hope this makes sense.
