Updated May 07, 2016. Trying to identify exactly how long Percocet is detectable in the body depends on many variables, including which kind drug test is being used. Percocet (oxycodone and acetaminophen) can be detected for a shorter time with some tests, but can be visible for up to three months in other tests.
On average, the oxycodone will take about 19.31 hours to clear from the system. The elimination of another ingredient, acetaminophen is shorter and the half-life usually lasts about 3.1 hours, which means that the acetaminophen will leave the system in about 17 hours. It can be shorter in some individuals where it is estimated about 11 hours where the half-life is approximately 2 hours. The full clearance of Percocet will leave the system in 24 hours which can be sometimes longer, up to 48 hours for some people.
