Hi, Thank you for your query. I can understand your concerns. Constipation usually is caused by the slow movement of stool through the colon.
Liver failure is the most dangerous complication of Percocet overdose, caused by acetaminophen toxicity. However, Percocet overdose can not only cause you health problems down the road, but it can potentially kill you if you take too many Percocet in one day.
Both oxycodone and Percocet decrease in efficacy if used over a long period of time. The usual side effects for both drugs are the same: dizziness, drowsiness, nausea, vomiting, constipation, dry mouth, lightheadedness and mood changes.
