Working through musculoskeletal cases always leaves me with a lot of questions…. it is satisfying when I have a few that I can answer concretely !!
When looking at a patient’s medications, you may see:
Tylenol PRN – which essentially just means they take it as needed for their pain.
Ok, I know what it means…but what does PRN stand for?
As most things in medicine, it has Latin origins:
Pro re nata
“As the circumstances arises”
