Percocet is a commonly prescribed pain medication combining oxycodone and acetaminophen. It’s widely used to manage moderate to severe pain, but many users and patients often wonder, how long does Percocet stay in your system? Understanding this is crucial, whether it’s for medical reasons, drug testing, or just personal knowledge.
In this comprehensive guide, we will cover everything you need to know about Percocet’s duration in your body, factors influencing its clearance, detection windows for various tests, and tips for safe use.

What Is Percocet?
Percocet is a prescription drug that contains two main active ingredients:
- Oxycodone: An opioid painkiller that works by altering the way the brain perceives pain.
- Acetaminophen: A non-opioid pain reliever that enhances oxycodone’s effects and also helps reduce fever.
Together, they offer effective relief for acute pain from injuries, surgeries, or chronic conditions. However, because oxycodone is an opioid, Percocet carries a risk of dependency and overdose if misused.
How Does Percocet Work In The Body?
When you take Percocet, oxycodone quickly enters your bloodstream and binds to opioid receptors in the brain and nervous system. This reduces the sensation of pain and creates a feeling of euphoria in some users.
Acetaminophen helps by blocking the production of certain chemicals that cause pain and inflammation.
The body then metabolizes Percocet primarily in the liver, breaking it down into inactive compounds that are eventually excreted through urine.
Factors Affecting How Long Percocet Stays In Your System
The duration Percocet remains detectable varies widely due to several factors:
Dosage and Frequency of Use
Higher doses or chronic use of Percocet can lead to accumulation in the body, extending the detection window. Occasional users clear the drug faster.
Metabolism Rate
People with faster metabolism break down drugs quicker. Metabolism can be influenced by age, genetics, liver function, and overall health.
Body Weight and Composition
Individuals with higher body fat percentages may retain the drug longer since oxycodone is somewhat lipophilic (fat-soluble).
Age
Older adults may process drugs slower due to reduced liver and kidney function, extending Percocet’s presence in the system.
Hydration and Kidney Function
Proper hydration and healthy kidneys help eliminate the drug faster through urine.
Other Medications
Certain medications can interfere with liver enzymes responsible for metabolizing oxycodone, altering its clearance time.
Percocet Half-Life Explained
The half-life of a drug is the time it takes for the concentration of the drug in your bloodstream to reduce by half. For Percocet, the half-life of oxycodone is approximately 3 to 4.5 hours.
This means after 4 hours, about half of the oxycodone is eliminated from your system. However, it usually takes about 5 to 6 half-lives for a drug to be mostly cleared from your body. So, oxycodone generally stays in your system for about 18 to 24 hours.
Acetaminophen, on the other hand, has a much shorter half-life of about 2 to 3 hours, so it clears faster than oxycodone.
Detection Windows: How Long Can Percocet Be Detected?
Detection windows depend on the type of drug test used. Here’s a breakdown of how long Percocet or oxycodone can be detected in different tests:
Urine Test
Urine is the most common method for drug screening.
- Percocet/oxycodone is detectable in urine for 2 to 4 days after the last dose.
- In chronic users, detection can extend up to 7 days.
Blood Test
Blood tests are less common and usually used in emergency or clinical settings.
- Percocet can be detected in blood for 12 to 24 hours.
Saliva Test
Saliva tests are less invasive but have shorter detection windows.
- Percocet can be found in saliva for up to 1 to 4 days.
Hair Follicle Test
Hair testing is used to detect long-term drug use.
- Percocet can be detected in hair for up to 90 days or longer.
Signs That Percocet Is Still In Your System
Even after the drug is mostly eliminated, some effects might linger depending on the dose and individual factors:
- Mild sedation or drowsiness
- Altered mood or mild euphoria
- Impaired coordination or thinking
If you experience prolonged symptoms, especially signs of overdose like difficulty breathing or severe confusion, seek medical help immediately.
How To Safely Use And Stop Percocet
Percocet should always be taken exactly as prescribed by your healthcare provider. Misuse can lead to dependence, addiction, or dangerous side effects.
Tips for Safe Use:
- Do not exceed prescribed doses.
- Avoid combining with alcohol or other sedatives.
- Inform your doctor of any other medications you are taking.
Tapering Off Percocet
If you’ve been using Percocet long-term, stopping suddenly can cause withdrawal symptoms such as anxiety, sweating, nausea, or shaking. Your doctor can help you taper off gradually to minimize discomfort.
What To Do If You Have A Drug Test Coming Up
If you have a drug test scheduled and have taken Percocet recently, keep these points in mind:
- Be honest with the testing authority about your prescription.
- Avoid taking Percocet unnecessarily.
- Drink plenty of water and maintain a healthy lifestyle to support metabolism.
- Remember that no detox product is guaranteed to speed up the elimination safely or effectively.
Potential Risks Of Percocet Remaining In Your System
Leaving Percocet in your system longer than expected can cause:
- Increased risk of side effects such as respiratory depression.
- Potential interactions with other medications.
- Impaired judgment or motor skills.
If you feel unusual or prolonged symptoms after taking Percocet, consult your healthcare provider.
Summary: How Long Does Percocet Stay In Your System?
| Test Type | Detection Window |
|---|---|
| Urine | 2 to 4 days (up to 7 days chronic) |
| Blood | 12 to 24 hours |
| Saliva | 1 to 4 days |
| Hair | Up to 90 days |
On average, oxycodone (the opioid in Percocet) remains detectable in your system for 1 to 4 days. The exact time depends on dosage, frequency, metabolism, and other personal factors.

Can Percocet cause a positive drug test?
Yes, Percocet can cause a positive result on drug tests that screen for opioids because it contains oxycodone. It’s important to disclose any prescribed use to the testing agency.
How long does Percocet take to start working?
Percocet usually begins to relieve pain within 15 to 30 minutes after oral intake, with peak effects occurring around 1 hour post-dose.

No. Drinking alcohol while taking Percocet can increase the risk of serious side effects like respiratory depression, sedation, and overdose.
How can I speed up the elimination of Percocet from my body?
There is no safe and guaranteed way to speed up the elimination of Percocet. Drinking water, staying active, and maintaining healthy liver and kidney function help, but metabolism mostly controls drug clearance.
