As Needed? What the HELL does that mean?

Hey doc, guess what?

You keep writing prescriptions like this, month after month?

Oxycodone 5mg #30

Sig: 1-2 Tablets PO Q4-6H PRN pain

The patient, never seems to understand the "as needed" part. They never seem to get better. They just want the same amount, month after month, year after year. It's not "as needed" anymore. It's for granted.
