Percocet combines oxycodone and acetaminophen to treat moderate to severe pain when non-opioid therapies aren’t enough. Your doctor will prescribe specific strengths, ranging from 2.5/325 mg to 10/650 mg, based on your pain level and medical history. You’ll typically take one tablet every six hours, but you shouldn’t exceed 4 grams of acetaminophen daily to protect your liver. Understanding proper dosing, potential side effects, and drug interactions helps you use this medication safely.
What Is Percocet?
Percocet is a name-brand form of Oxycodone, or more precisely, an opioid-based prescription drug. The distinction is that Percocet also contains acetaminophen, a milder pain treatment often found in over-the-counter medications. This makes Percocet more effective than Oxycodone by itself.
Percocet combines two pain-relieving compounds, oxycodone hydrochloride and acetaminophen, to treat moderate to severe pain. Oxycodone, a semisynthetic opioid derived from thebaine, binds to mu, kappa, and delta receptors in your CNS, with strongest affinity for mu receptors. This binding inhibits adenylate cyclase, decreases cAMP levels, and alters how you perceive pain.
Acetaminophen works differently, it inhibits prostaglandin synthesis and blocks endogenous pyrogen action on your hypothalamic heat-regulating centers. This non-opioid component enhances Percocet‘s overall analgesic effect.
You’ll find Percocet in several strengths: 2.5/325 mg, 5/325 mg, 7.5/325 mg, 7.5/500 mg, 10/325 mg, and 10/650 mg. The first number indicates oxycodone content; the second represents acetaminophen dosage.
Percocet is FDA-approved to treat moderate to severe pain patients, especially chronic and cancer-related pain. Because Percocet contains acetaminophen, it can also help alleviate fever-related issues such as fatigue, chills, and muscle aches.
Endo Pharmaceuticals is the manufacturer of Percocet, also produced under other name brands such as:
- Endocet
- Magnacet
- Narvox
- Perloxx
- Pimalev
- Roxicet
- Roxilox
- Tylox
- Xartemix XR
- Xolox

When Doctors Prescribe Percocet
When pain becomes moderate to severe and non-opioid therapies fail to provide relief, physicians turn to Percocet as a treatment option. Your doctor typically prescribes initial doses of 5-15 mg every 4-6 hours for acute pain, while chronic pain management starts lower at 2.5-10 mg on scheduled intervals.
Before prescribing, your physician conducts a thorough medical history review and screens for substance abuse risk. They’ll check prescription drug monitoring program reports and document a risk-benefit analysis in your medical record. You should inform your doctor if you have a family history of substance abuse, depression, or mental illness, as these factors increase risk. Many clinicians report insufficient training in prescribing opioids, which has prompted the development of clearer prescribing guidelines.
Effective opioid pain management requires starting at the lowest effective dose. Many states limit initial acute prescriptions to seven-day supplies. Your doctor must obtain informed consent, discussing both benefits and risks. For post-surgical or injury-related pain, expect short treatment courses with close follow-up appointments.
What Does Percocet Look Like?
If you are unsure which tablet’s dosage is, the manufacturer has given each tablet its own unique look.
- Percocet 2.5 mg or 325 mg, Oval shape, pink, one side engraved with “Percocet,” the other with “2.5”
- Percocet 5 mg or 325 mg, Round shape, blue, one side engraved with “Percocet,” the other with “5”
- Percocet 7.5 mg or 325 mg, Oval shape, peach, one side engraved with “Percocet,” the other with “7.5/325”
- Percocet 10mg or 325mg, Capsule-shape, yellow, one side engraved with “Percocet,” the other with “10/325”
Percocet Dosages and Forms
Percocet can come in various forms, such as liquid, concentrated liquid, extended relief capsules, or extended relief tablets. Tablets are the most commonly prescribed type of Percocet.
The frequency and dosage can vary based on the delivery method, the dosage, and the patient’s other medications and medical history. It is essential to disclose all of your medications to doctors in order to avoid interactions between drugs.
The instructions for adults are one tablet every six hours as needed for the pain. Since Percocet does not treat medical conditions and is used only for comfort, it is not required to take every six hours. If the patient is not in pain or the previous dose is still providing relief, it is okay to wait to take more.
What Is the Dosage for Percocet?
Percocet is typically prescribed in the following dosages:
- Percocet 2.5 mg or 325 mg, not to exceed 12 tablets in 24 hours
- Percocet 5 mg or 325 mg, not to exceed 12 tablets in 24 hours
- Percocet 7.5 mg or 325 mg, not to exceed eight tablets in 24 hours
- Percocet 10 mg or 325 mg, not to exceed six tablets in 24 hours
Important: Regardless of strength, don’t exceed 4 grams of acetaminophen daily to prevent liver damage. Avoid taking other acetaminophen-containing products while using Percocet.
Who Shouldn’t Take Percocet?
You shouldn’t take Percocet if you have severe respiratory conditions like acute asthma, COPD, or any breathing disorder that causes respiratory depression. The oxycodone component can further suppress your breathing, creating life-threatening complications. If you have liver impairment, the acetaminophen in Percocet poses serious toxicity risks, as your liver can’t properly metabolize the medication.
Respiratory Condition Patients
Patients with respiratory conditions face serious risks when taking Percocet, as oxycodone directly suppresses the brain’s respiratory drive. If you have acute bronchial asthma, COPD, or significant respiratory depression, the FDA contraindicates opioids like this oxycodone acetaminophen combination. The overdose risk and addiction potential increase substantially when your breathing is already compromised.
| Condition | Risk Level |
|---|---|
| Severe bronchial asthma | Contraindicated |
| COPD with cor pulmonale | Contraindicated |
| Upper airway obstruction | Contraindicated |
| Pre-existing respiratory depression | Contraindicated |
Understanding Percocet uses means recognizing when you shouldn’t take it. If you experience hypoxia, hypercapnia, or sleep apnea, you’re at heightened risk for life-threatening respiratory depression, particularly during the first 24-72 hours. Your liver must also metabolize acetaminophen, compounding concerns in compromised patients.
Liver Impairment Cases
Given that Percocet contains acetaminophen, a compound metabolized primarily in the liver, individuals with hepatic impairment face markedly amplified risks when taking this medication. If you have liver disease, your body clears oxycodone more slowly, with elimination half-life extending from normal ranges to 4.6-24.4 hours. This delayed clearance increases drug accumulation and intensifies effects.
You’ll need significant dosage adjustments if you have severe hepatic impairment, typically a 30%-50% reduction from standard starting doses. The acetaminophen component poses additional dangers, as hepatotoxicity has occurred in chronic alcoholics even at therapeutic doses.
Watch for liver toxicity symptoms: yellowing skin or eyes, dark urine, upper abdominal pain, pale stools, and unusual fatigue. If you experience these warning signs, contact your care team immediately. Avoid alcohol completely while taking Percocet.
Percocet Side Effects: Common and Serious
The most basic definition of a side effect is any reaction other than the drug’s intended and prescribed use. Side effects of medications are usually discovered during well-documented trial periods. Doctors will typically tell patients what they can expect to experience. Side effects are generally unpleasant and may vary based on the individual. Side effects will resolve on their own after a couple of days of use once the body adjusts or once the course of treatment ends. If the side effects outweigh the benefit of the medication or become unbearable, you should always call your doctor.
Side effects of Percocet include, but are not limited to:
- Nausea
- Vomiting
- Upset stomach
- Constipation
- Dry mouth
- Sweating
- Headache
- Dizziness
- Drowsiness
- Headache
- Itching
- Blurred vision
- Slowed reactions
Percocet offers powerful pain relief, but understanding its side effects is essential for safe, effective use.
Common Side Effects
You’ll likely experience gastrointestinal issues first. Nausea, vomiting, and constipation affect over 5% of patients. Dry mouth and appetite loss occur frequently. Neurologically, expect drowsiness, dizziness, and headaches. These effects increase your fall risk, particularly if you’re elderly.
Serious Side Effects
Watch for respiratory depression, it’s potentially fatal. Shallow breathing, hypotension, and bradycardia require immediate medical attention. Acetaminophen in Percocet poses liver damage risks, including hepatic necrosis during overdose. Serious skin reactions like Stevens-Johnson Syndrome demand urgent care.
Withdrawal and Overdose
Don’t stop Percocet abruptly. Withdrawal triggers nausea, diarrhea, and sweating. Overdose signs include unconsciousness and labored breathing, call emergency services immediately.
Adverse Effects
Some people use the terms “side effects” and “adverse effects” interchangeably, but they are not the same thing. As defined above, side effects are expected and usually resolve on their own.
There are two types of adverse effects: predictable but not guaranteed, ranging from mild to severe, depending on the dosage. The second kind of adverse reaction is unpredictable and usually presents in patients with an allergy to the medication or other susceptibility factors.
Unfortunately, there is no way to know if a patient is intolerant or allergic to medication if they’ve never taken it, or any version of it, previously.
A doctor should be contacted immediately if any of the following adverse effects from Percocet use occur:
- Confusion
- Disorientation
- Fever
- Chills
- Unsual thoughts or behavior
- Loss of appetite
- Upper stomach pain
- Breathing problems
- Trouble urinating
- Dark urine
- Shaking or tremors
- A change in stool color
- Rash or skin reactions
- Swelling anywhere on the body
- Yellowing of skin or eyes
- Ringing in the ears
- Irregular heartbeat
- Overdose
- Death
Potential Interactions
It is always important to tell your doctor everything you are taking to avoid drug interactions, even if it is not a prescription medicine. This includes any herbal supplements, allergy medications, and vitamins. Since Percocet is prescribed for cancer and chronic pain, older adults typically use it, so the likelihood they are on other maintenance medications is high.
Taking Percocet alongside other medications requires careful attention to potentially dangerous interactions that can amplify side effects or trigger life-threatening complications.
You must avoid combining Percocet with CNS depressants like benzodiazepines, alcohol, sleep medications, or muscle relaxers. These combinations carry an FDA boxed warning for fatal respiratory depression and overdose.
CYP3A4 inhibitors, including certain antibiotics and antifungals, increase oxycodone levels in your blood, potentially causing dangerous adverse reactions. Conversely, inducers like rifampin reduce Percocet’s effectiveness while raising acetaminophen-related liver damage risk.
Don’t take additional acetaminophen-containing products, as exceeding safe limits causes liver toxicity. Avoid MAO inhibitors and mixed opioid agonist/antagonists, which can precipitate withdrawal.
Some of the most common medications that can result in adverse reactions and side effects with oxycodone use are:
- Antibiotics
- Antifungals
- Blood pressure and heart medication
- Seiure medication
- Diuretics or “water pills”
- HIV medications
- Hepatitis C medications
- Opioid medications
- Sedatives such as Valium, Xanax Klonopin
- Muscle relaxers
- Depression medication
- Sleeping aids
- Cloud and flu medication
Long-Term Effects of Percocet
Long-term effects can last months, weeks, years, or a lifetime. People who use or abuse medication outside of its prescribed time frame and dosage are more likely to develop long-term effects. Some long-term effects are reversible with proper treatment, and some can be managed under a doctor’s care.
Long-term effects of Percocet use include:
- Depression
- Anxiety
- Irritability
- Hallucinations
- Seizures
- Hypotension, low blood pressure
- Hypertension, high blood pressure
- Tachycardia, elevated heart rate, 100 beats per minute or more
- Brydycardia, slo heart rate, 60 beats per minute or less
- Cerebral edema, fluid on the brain
- Hyperkalemia, or potassium in the blood
- Kidney failure
- Metabolic acidosis, low PH in the blood
- Respiratory alkalosis, too much base in the blood or body
- Chronic indigestion
- Intestinal Obstruction
- Intestinal paralysis
- Hepatitis
- Jaundice
- Liver failure
- Hearing loss
- Hypoglycemia, low blood sugar
- Hyperglycemia, high blood sugar
- Muscle pain and weakness
- Red eyes
- Pupil dilation
- Insomnia
- Chronic drowsiness
How Long Does Percocet Stay in Your System?
One dose of Percocet taken as prescribed will remain in the bloodstream for about 12 hours and will take approximately 24 hours to process out of the body entirely.
For chronic users and those taking more than the prescribed amount, this can vary. A user’s physical attributes such as weight, height, and underlying conditions also contribute to how the body will process, store, and expel narcotics.
With regular usage, Percocet withdrawal begins within several hours after the last dose. The withdrawal process will be different for everyone, and people addicted to medication will have a more prolonged and typically more intense withdrawal or come down when they stop using.
Percocet Withdrawal Symptoms
Many Percocet users become dependent on the drug and will experience a range of symptoms when they cease to use it. In severe cases, especially in long-term users, medical assistance is recommended. In rare cases, withdrawal symptoms can be fatal.
Users may be physically dependent, psychologically dependent, or both; a professional care team will assess this and develop a treatment plan as needed. Always consult a doctor before stopping any prescribed medication. The patient is advised to taper off for most medications instead of stopping abruptly or “going cold turkey.”
Symptoms of Percocet withdrawal include:
- Sweating
- Goosebumps
- Anxiety
- Vomiting
- Insomnia
- Muscle pain
- Headaches
- Abdominal cramps
- Irritability
- Diarrhea
- Trouble regulating body temperature, hot flashes, and chills
- Depression
- Suicidal thoughts
- Cramping
- Muscle spasms
- Shaking
- Increased heart rate
- High blood pressure
- Loss of appetite
- Coma
- Death
How Do I Know if I’m Addicted to Percocet?
Addiction can come about slowly or suddenly and is often hard to spot in the early stages. Addiction is defined as abnormal, excessive, compulsive, and continued non-medical use of any substance despite problems that arise from self-medicating.
Addicts will often hide or excuse their behaviors from people close to them because of a sense of guilt and shame. Drug-seeking behaviors can present themselves in various ways, including:
- Pill seeking behaviors, asking people to share their medications
- Frequently requesting medication for multiple injuries
- Visiting different doctors or “doctor shopping”
- Not disclosing other prescriptions
- Lying about conditions
- Tampering with prescriptions
- Pill hiding
- Stocking up or storing medication in several places
Some people will resort to buying or stealing drugs from family and friends or buying from dealers. Obtaining drugs from channels not approved by the FDA is extremely dangerous and can become tainted with lethal doses of other substances.

Frequently Asked Questions
How Long Does Percocet Stay in Your System After Taking It?
Percocet stays in your system for varying lengths depending on the test used. You’ll typically clear it from your blood within 24 hours, but it remains detectable in your urine for 3-4 days after your last dose. Saliva tests can detect it for up to 2 days, while hair follicle tests may show use for up to 90 days. Your metabolism, liver function, and dosage frequency all affect these windows.
Can You Drink Alcohol While Taking Percocet?
No, you shouldn’t drink alcohol while taking Percocet. Combining these substances creates dangerous synergistic effects on your central nervous system. Both suppress respiratory function, oxycodone alone at 20mg reduces respiration by 28%, and adding alcohol drops it further. You’re risking respiratory depression, overdose, coma, and potentially fatal outcomes. The acetaminophen component also increases your liver damage risk when mixed with alcohol. Complete alcohol avoidance is strongly recommended during Percocet use.
What Should You Do if You Miss a Percocet Dose?
Take the missed dose as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the missed one and return to your regular schedule. Don’t double up to compensate, doing so can cause excessive drowsiness, breathing difficulties, and overdose risk. For extended-release formulations, never take more than one dose within 12 hours. If you’re uncertain about timing, contact your pharmacist or physician for guidance.
Is It Safe to Drive or Operate Machinery While on Percocet?
No, you shouldn’t drive or operate machinery while taking Percocet. Oxycodone causes drowsiness, dizziness, and impairs your cognitive functioning, reaction time, and judgment. Studies show opioid use doubles your crash risk, and drivers testing positive exhibit increased lane weaving and poor coordination. It’s illegal throughout America to drive under opioid influence. You should develop alternative transportation strategies and consult your physician about when it’s safe to resume driving after treatment.
How Do You Safely Stop Taking Percocet Without Withdrawal Symptoms?
You can safely stop taking Percocet by gradually tapering your dose under medical supervision rather than quitting abruptly. Your doctor will create a reduction schedule that allows your body to adjust slowly, minimizing withdrawal symptoms. Don’t attempt to taper on your own, medical providers can monitor your progress and address complications. If you’ve been taking Percocet long-term, consider medically supervised detox, where professionals manage symptoms and prevent dehydration or other risks.
