Less than a week: The drug metabolite may be detectable for 2-3 days after a single intake. You may consult this site for more information on this topic: http://www.mayomedicallaboratories.com/test-info/drug-book/viewall.html For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex, if you have sex. Get HPV vaccine.

Good question, the Percocet can stay detectable in your blood for 24 hours, saliva 2days, urine 4 days and hair up to 90 days !! The medicine itself between 4-5.5 hours while metabolites of the drug are what I just mentioned earlier !!
