Oxycodone Dosing Error

I got a call a couple of weeks ago from a grieving father. He found his 27 year old son dead in his bed one morning in February. His son had earlier that day been to a new doctor for his chronic back pain, and the doctor had prescribed 120mg of oxycontin /oxycodone without any information from the young man that he could tolerate this high dose. The labelling for oxycontin describes a starting dose of 10 mg. The cause of death has been ruled oxycodone toxicity.
