What is Percocet

Percocet is the brand name for the oxycodone/acetaminophen combination, which is used to treat moderate to severe short-term pain.

Oxycodone is a semi-synthetic opioid analgesic, while acetaminophen is a non-narcotic pain medication. The drug is highly addictive because of its tendency for uplifting moods close to euphoric levels.



How long does Percocet take to leave your system

Studies show that Percocet has an average half-life of around 3.5 hours. As per the ‘rule of thumb’, it would generally take around 19-24 hours for Percocet to be completely eliminated from your system after the last dose.

The elimination time may, however, vary depending on the dosage and frequency of Percocet ingestion, along with certain individual factors. These include age, physical build, inherited genes, hydration levels, BMR, and food intake.

When the liver metabolizes Percocet, certain metabolites are created that are detectable in various drug tests. This is because said metabolites may stay in a person’s system longer than the parent drug.

How long does Percocet stay in your urine, blood, saliva, and hair follicle

Saliva Test 1-4 days
Hair follicle Test Up to 30-35 days (but results are not always accurate)

How to pass a Percocet drug test

Here are some tips that can help you pass your Percocet drug test:

  • Staying hydrated: Drink lots of water throughout the day.
  • A healthy diet: Proper nutrition is a necessity when it comes to the removal of any drug from your system.
  • A daily workout regime:  Light exercise helps blood circulation and metabolism, thus detoxifying your system of Percocet.
