As far as other side effects, well of course there is the liver which you mentioned and the kidneys. Thankfully there isn't tylenol in the oxycontin
, but the tylenol with percs is surely compromising these organs' well being. My very good friend, a percocet abuser, just got off a dialysis machine 2 days ago, for failed liver and kidney function. He is an otherwise healthy 32 year old man. Then there are changes that occur to the brain, that in many cases can be permanent.
