Why Does Percocet Stay In Your System For That Long?

Whenever you ingest something in your body, it will go through different processes before leaving your body.

Based on their composition, different opioids have a different life cycle and diverse period for which it stays in the human body. However, the formation is not the only factor. Several factors determine how long Percocet is going to stay in your body.

The different reasons why it takes so much time for Percocet to leave the body are listed below:

  • Apart from the composition of Percocet, a primary reason why it stays in your body for a long time. The other factor is the age of a person. The older a person gets, the longer it takes for the Percocet to leave your body effectively.
  • Now, another thing that can determine the longevity of traces of Percocet in the human body is the dosage you take. If the dosage of Percocet is high, the chances are it will build up over time and hence will take a long to get it totally out of your system.
  • The health condition can also be a factor that will determine how long Percocet will stay in the system. If a person has kidney or liver issues, it will take longer for Percocet to leave the system. And if the kidney or liver is healthy, then Percocet can leave the body sooner.
  • And then comes the metabolism rate of a person. The higher the metabolism rate, the shorter the duration for which Percocet will stay in the system. Usually, for a person who does a lot of physical activity or is young, Percocet leaves the body in a short span. However, the metabolism also reduces when a person ages.


Percocet is an opioid that is advised to patients to deal with mild to severe pain. It often stays in the body for a long time like other opioids. However, it will remain longer if you use it frequently or take a high dosage.

After some time, the traces of Percocet gets washed out of the human system forever.
