Hi, i've taken percocet 10/325 for the better part of 3 weeks and average of 3-4 daily. stopping now, how long until it'll be out of my urine? thanks!

48-72 hrs: If prescribed, then it is reported as a negative result by the medical review officer. However, to further detail elemination it depends on how the urine is processed qualitative or quantitative.. Sometime a positive (qualitative)will be followed by quantitative to determine how much is present and it's concentration compared to known times and concentrations. So a more simple answer is 48-72 hrs.

Agree though:: Predicting when urine would be negative is a bit uncertain. These tests stays positive longer when there has been longer use. I feel weird since it sounds like you are trying to beat a test. As answer wisely notes above, if prescribed, you wouldn't be dinged for taking doctor approved percocet. Clearance is variable, from 1-5 days, if you research detection timetables.
