How Long Does Percocet Stay In Your System?

The two active ingredients in Percocet are oxycodone and acetaminophen. Oxycodone has a blood test detection window of up to 24 hours.

Oxycodone has a high potential for addiction, so Percocet must be used with extreme caution. Consult your professional treatment team to determine if Percocet is the right opioid to help manage your pain.

Percocet: The Prescription Painkiller

Percocet is a schedule II painkiller drug developed by Endo Pharmaceuticals in Malvern, Pennsylvania. It depresses your central nervous system and dulls your subjective sensation of pain by binding to hormone receptors. The active ingredients are oxycodone (an opioid) and acetaminophen (a non-opioid):

Oxycodone

Oxycodone helps manage moderate to severe pain by binding to the opioid receptors, with the strongest affinity being for mu-type receptors.[1]

Oxycodone’s potency is due to its specific affinity for opioid receptors rather than a comparison to natural dopamine.

Oxycodone, and by extension, Percocet, carries a high risk of addiction. The Schedule II classification means you cannot legally have Percocet without a prescription. Use with caution and only with the direction of your attending physician.

In 2021, prescription opioid overdoses, which included many comprised of Oxycodone, accounted for 16,706 deaths in the United States.[2]

Acetaminophen

While acetaminophen’s mechanism of action is not well understood, it appears to help treat fever and pain by inhibiting the cyclooxygenase (COX) pathways in the brain selectively, which is believed to inhibit the synthesis of prostaglandins.[3]

Prostaglandins cause inflammation, pain, and fever at your infection sites in order to stimulate healing.[4] Blocking these means you will have milder symptoms. Acetaminophen is in a class of medications called analgesics (pain relievers) and antipyretics (fever reducers).

Acetaminophen is less addictive than Oxycodone, but it’s toxic in large amounts and possible to overdose fatally while taking it:[5]

Toxic levels of acetaminophen are the first leading cause of liver transplants in the United States and the second leading cause of liver transplants worldwide.

Acetaminophen overdoses were responsible for 56,000 ER visits and 2,600 hospitalizations. Tragically, 500 deaths per year in the U.S. are attributed to acetaminophen toxicity.

Fifty percent of these deaths are unintentional overdoses.

Around 60 million Americans use Acetaminophen on a weekly basis.[6] The danger is that sometimes you use products in combination with each other without realizing acetaminophen is contained in both.

Taking two or more Acetaminophen combination products could yield a toxic and fatal dose. Here are some common medications that contain acetaminophen:

  • Tylenol
  • Robitussin
  • Excedrin
  • NyQuil

How Long Does Percocet Stay In Your System?

Percocet contains acetaminophen and oxycodone. Of the two active ingredients, Acetaminophen is available in over-the-counter medications, while Oxycodone is a Schedule II controlled substance. The only one you would be screened for is Oxycodone. Oxycodone can be detected in blood for up to one day and in hair for up to 90 days.

How Long Does Percocet Take to Kick In?

It takes about 30 minutes to begin feeling the effects of Percocet. Once you begin feeling the effects, it should last for 4 to 6 hours.

What Is The Half-Life of Percocet?
Oxycodone generally has a half-life of approximately 3 to 5 hours, while the half-life of acetaminophen is around 2 hours.[7][8]

A half-life is defined as the amount of time it takes for 50% of a given substance to be eliminated from your body. It takes 4 to 5 successive half-life eliminations to achieve 95% elimination of a given substance from your body.

Other Forms of Percocet Drug Testing

Urine

Blood Hair

Saliva

Oxycodone is detectable in urine 3 to 4 days after dosing. Oxycodone is detectable in blood up to 1 day after dosing. Oxycodone is detectable in hair 90 days after dosing. Oxycodone is detectable in saliva 1 to 4 days after dosing.

Effects of Long-Term Percocet Use

Effects of Long-Term Percocet Use

The main effects of long-term Percocet use are possible dependency and addiction.[9] If your body builds up a tolerance to oxycodone, it would require a more and more potent dose to achieve the same pain reduction, which can increase the risks of side effects and dependency.

Besides dependency, oxycodone affects your gastrointestinal, digestive, and nervous systems differently:

  • Respiratory: You could have breathing problems like respiratory depression.
  • Digestive: You could have gut problems like vomiting, constipation, and a bloated stomach.
  • Nervous: You could be fatigued.

Treatment For Painkiller Addiction

Painkiller addiction has the potential to derail your life. Do not let substance use disorder determine what is possible for you or your future.

There are a wide variety of treatments that can help you get on the road to recovery. You will meet with a clinical treatment team to create a comprehensive assessment that takes into consideration your background, lifestyle, and goals.

Some combination of detox, inpatient, residential treatment, IOP (Intensive Outpatient Programs), Outpatient, and PHP (Partial Hospitalization Programs) could be included.
