Any patient requiring 10 doses of
oxycodone per day is not receiving proper or even effective
treatment, and the doctor is putting the patient at risk of addiction, respiratory suppression, and overdose.
I would have some idea of when doctors prescribe too much, since it happened to me long ago.
Pain management properly done, is about reducing pain to manageable levels, not eliminating all pain, which can not be done when dealing with chronic conditions.
