On a prescription form what does PRN mean and when is it used?

Question:

Looking at prescriptions written by my DR today and was just curious what the PRN means in the lower corner by the refill instructions.

Answers:
yep yep as needed.

Pro re nata - Latin literally meaning "For the thing born," but commonly used to mean "as needed" or "as the situation arises."

It is generally used as the acronym PRN in medicine to refer to dosage of prescribed medication that is not scheduled; instead administration is left to the caregiver or the patient's prerogative

Most often PRN medications are analgesics such as paracetamol (Tylenol) or hydrocodone (Vicodin), laxatives such as coloxyl, sleeping aids (sedatives) such as zolpidem (Ambien) or lorazepam (Ativan), and anti-emetics such as ondansetron or dimenhydrinate (Gravol).

as needed

It means to dispense as needed. It's used when the doctor feels you can manage your own condition with the medication given.

its latin - pro re nocta. It means as needed instead of a daily routine.. Think of it as applying to aspirin or Tylenol OTC.. You only take those as needed but not necessarily every day BID/TID, etc.

patient requests need...as needed
