Greetings.
The main problems associated with the Percocet is a physical dependence and gradual tolerance developing with the doses which need further increase in the medication and addiction liability. In long term it would give craving for the medication and serious physical and psychological dependence. Percocet contains acetaminophen. The high doses of acetaminophen used regularly for long term can cause irreversible liver damage. So he needs to go to a rehab facility as soon as possible for the treatment.
Please feel free for your follow up questions.
