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.
Oxycodone, one of the drugs in Percocet, can be detected in a blood test for approximately 24 hours after it is taken, according to About.com. The other drug in Percocet is acetaminophen, a less potent non-opioid found in over-the-counter medications such as Tylenol.
