Oxycodone immediate-release and Percocet begin working within 15 to 30 minutes of taking them, reach their peak effect within 1 hour, and last for 3 to 6 hours.
Oxycodone extended-release tablets are longer-acting. They start to relieve pain within 2 to 4 hours of taking them, and steadily release the oxycodone for about 12 hours.
Both medications can stop providing effective pain relief when taken long-term. This is called tolerance. When you begin to develop a tolerance to a drug, you need higher doses to get pain relief.
This is normal with long-term opiate use. How quickly a person develops a tolerance varies. Your body will begin to adapt to the medication in as little as one week of taking regular doses. Oxycodone is more likely to cause dizziness and feelings of euphoria. Percocet contains acetaminophen, which can affect the liver and cause side effects such as upper abdominal pain , black or tarry stools , and yellowing of the skin and eyes.
In low doses, acetaminophen can cause elevated liver enzymes. Taking too much acetaminophen can cause liver damage or liver failure. The risk of liver damage is higher if you already have liver problems, take warfarin, or drink more than three alcoholic beverages per day.
Both oxycodone and Percocet are considered highly addictive and can cause dependence and addiction. Tolerance can lead to physical dependence and physical and mental withdrawal symptoms when the drug is stopped. Oxycodone and Percocet are classified as schedule II drugs. Schedule II drugs have a high potential for misuse. Both can cause physical dependence and opioid addiction. Physical dependence occurs when your body develops a tolerance to the drug, requiring more of it to achieve a certain effect.
When your body becomes dependent on the drug, you can experience mental and physical symptoms if you stop taking the drug abruptly. These are called withdrawal symptoms. Physical dependence can occur even when you take oxycodone or Percocet as directed.
These are then excreted by the kidneys into the urine. The half-life of oxycodone, which refers to the amount of time it takes half the drug to be effectively eliminated from your body, is about 3. It takes several half-lives to fully eliminate a drug, and everyone metabolizes medication differently, depending on factors such as age, weight, genetics, and even specific health issues.
Over time, you may develop a tolerance to oxycodone, which means that it might not relieve pain as well as it originally did. Talk to your doctor if this happens. Never take more than your prescribed dose of oxycodone. Your doctor may decide to increase your prescribed dose or switch you to a different type of pain reliever. Oxycodone's action is effectively eliminated from the blood in For most people, the effects of the drug will be completely worn off after 24 hours.
However, the drug remains detectable in the body for much longer, even after its effects have worn off. Oxycodone will be detected by typical employment, medical, and forensic "drugs of abuse" screening tests.
With a home testing kit, someone who has taken oxycodone will start to test positive for the drug within one to three hours, and the result will continue to be positive for one to two days, according to the Food and Drug Administration FDA. The following is an estimated range of times, or detection windows, during which oxycodone can be detected by various testing methods. Oxycodone is detectable in a urine test for three to four days after the last dose. A standard urine drug screen usually does not test for oxycodone, so additional tests must be used to detect the presence of the drug.
In blood tests, the drug is detectable in for up to 24 hours. Oxycodone can also be detected by a saliva test for one to four days after use. The drug can be detected by a hair follicle test for a much longer period of time than other test types—up to 90 days. These are only estimated as the metabolism of oxycodone varies. If you're taking oxycodone by prescription, you should disclose this to the laboratory so they can interpret your test results accurately. There are a number of factors that can play a role in how long oxycodone can be detected in your body.
Oxycodone can build up in your body, so if you have been taking oxycodone for pain for some time, it will be detectable for a longer period of time after you have taken your last dose. If you are taking a drug test, you should inform the lab even if you have stopped taking the drug. Studies have shown that older adults clear the drug from their systems at a slower rate than younger adults. People with impaired kidney function clear oxycodone at a slower rate. People with impaired liver function may also take longer to clear oxycodone from their systems.
For this reason, the FDA recommends that those with liver problems should take starting doses that are a third or half of the usual beginning dose. There are a few things that might help slightly speed up how quickly oxycodone is processed and eliminated from your system. The first step is to stop taking the drug; however, you should never stop taking your medication without first talking to your doctor.
Because oxycodone can lead to physical dependence, you may experience symptoms of opioid withdrawal if you stop taking it suddenly. Once you have safely discontinued the use of oxycodone, you can speed up the drug's clearance from your system by staying well-hydrated, getting regular exercise, and eating a healthy diet.
Drinking plenty of fluids can help dilute the presence of the drug in urine, while physical activity and nutritious eating might help boost your body's metabolism of the drug. Knowing how long oxycodone remains in your system is important because of the threat of overdose and dangerous interactions with alcohol and other medications.
A person caring for you can give the naloxone if you stop breathing or don't wake up. Your caregiver must still get emergency medical help and may need to perform CPR cardiopulmonary resuscitation on you while waiting for help to arrive. Anyone can buy naloxone from a pharmacy or local health department.
Make sure any person caring for you knows where you keep naloxone and how to use it. Avoid driving or operating machinery until you know how this medicine will affect you. Dizziness or drowsiness can cause falls, accidents, or severe injuries. Ask a doctor or pharmacist before using any other medicine that may contain acetaminophen sometimes abbreviated as APAP. Taking certain medications together can lead to a fatal overdose. Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Opioid medicine can slow or stop your breathing, and death may occur. In rare cases, acetaminophen may cause a severe skin reaction that can be fatal. This could occur even if you have taken acetaminophen in the past and had no reaction. Serious breathing problems may be more likely in older adults and in those who are debilitated or have wasting syndrome or chronic breathing disorders. This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects.
You may have breathing problems or withdrawal symptoms if you start or stop taking certain other medicines. Tell your doctor if you also use an antibiotic, antifungal medication, heart or blood pressure medication, seizure medication, or medicine to treat HIV or hepatitis C.
Opioid medication can interact with many other drugs and cause dangerous side effects or death. Be sure your doctor knows if you also use:. This list is not complete.
Other drugs may affect acetaminophen and oxycodone, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here. Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
Every effort has been made to ensure that the information provided by Cerner Multum, Inc. Drug information contained herein may be time sensitive. In a study of patients with end stage renal impairment, mean elimination half-life was prolonged in uremic patients due to increased volume of distribution and reduced clearance. Oxycodone should be used with caution in patients with renal impairment. Because oxycodone is known to be substantially excreted by the kidney, its clearance may decrease in patients with renal impairment.
Initiate therapy with a lower than usual dosage of oxycodone and acetaminophen tablets and titrate carefully. The following adverse reactions have been identified during post approval use of oxycodone and acetaminophen tablets.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. The most frequently observed non-serious adverse reactions include lightheadedness, dizziness, drowsiness or sedation, nausea, and vomiting. These effects seem to be more prominent in ambulatory than in nonambulatory patients, and some of these adverse reactions may be alleviated if the patient lies down.
Other adverse reactions include euphoria, dysphoria, constipation, and pruritus. Hypersensitivity reactions may include: Skin eruptions, urticarial, erythematous skin reactions. Hematologic reactions may include: thrombocytopenia, neutropenia, pancytopenia, hemolytic anemia. Rare cases of agranulocytosis have likewise been associated with acetaminophen use. In high doses, the most serious adverse effect is a dose-dependent, potentially fatal hepatic necrosis.
Renal tubular necrosis and hypoglycemic coma also may occur. Body as a Whole: Anaphylactoid reaction, allergic reaction, malaise, asthenia, fatigue, chest pain, fever, hypothermia, thirst, headache, increased sweating, accidental overdose, non-accidental overdose.

Anaphylaxis : Anaphylaxis has been reported with ingredients contained in oxycodone and acetaminophen tablets.
Oxycodone and acetaminophen tablets contain oxycodone, a substance with a high potential for abuse similar to other opioids including fentanyl, hydrocodone, hydromorphone, methadone, morphine, oxymorphone, and tapentadol. All patients treated with opioids require careful monitoring for signs of abuse and addiction, since use of opioid analgesic products carries the risk of addiction even under appropriate medical use. Prescription drug abuse is the intentional non-therapeutic use of a prescription drug, even once, for its rewarding psychological or physiological effects.
Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that develop after repeated substance use and includes: a strong desire to take the drug, difficulties in controlling its use, persisting in its use despite harmful consequences, a higher priority given to drug use than to other activities and obligations, increased tolerance, and sometimes a physical withdrawal.
Preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with poor pain control. Abuse and addiction are separate and distinct from physical dependence and tolerance. Healthcare providers should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. In addition, abuse of opioids can occur in the absence of true addiction. Oxycodone and acetaminophen tablets, like other opioids, can be diverted for non-medical use into illicit channels of distribution.
Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests, as required by state and federal law, is strongly advised. Proper assessment of the patient, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.
Risks Specific to Abuse of Oxycodone and Acetaminophen Tablets Oxycodone and acetaminophen tablets are for oral use only. Abuse of oxycodone and acetaminophen tablets poses a risk of overdose and death.
The risk is increased with concurrent abuse of oxycodone and acetaminophen tablets with alcohol and other central nervous system depressants. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV. Both tolerance and physical dependence can develop during chronic opioid therapy. Tolerance is the need for increasing doses of opioids to maintain a defined effect such as analgesia in the absence of disease progression or other external factors.
Tolerance may occur to both the desired and undesired effects of drugs, and may develop at different rates for different effects. Physical dependence is a physiological state in which the body adapts to the drug after a period of regular exposure, resulting in withdrawal symptoms after abrupt discontinuation or a significant dosage reduction of a drug. Withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity e. Physical dependence may not occur to a clinically significant degree until after several days to weeks of continued opioid usage.
Rapid tapering of oxycodone and acetaminophen tablets in a patient physically dependent on opioids may lead to serious withdrawal symptoms, uncontrolled pain, and suicide. Rapid discontinuation has also been associated with attempts to find other sources of opioid analgesics, which may be confused with drug-seeking for abuse. When discontinuing oxycodone and acetaminophen tablets, gradually taper the dosage using a patient-specific plan that considers the following: the dose of oxycodone and acetaminophen tablets the patient has been taking, the duration of treatment, and the physical and psychological attributes of the patient.
To improve the likelihood of a successful taper and minimize withdrawal symptoms, it is important that the opioid tapering schedule is agreed upon by the patient. Following an acute overdosage, toxicity may result from the oxycodone or the acetaminophen.
Clinical Presentation Acute overdosage with oxycodone can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations. Acetaminophen Dose-dependent potentially fatal hepatic necrosis is the most serious adverse effect of acetaminophen overdosage.
Renal tubular necrosis, hypoglycemic coma, and coagulation defects may also occur. Early symptoms following a potentially hepatotoxic overdose may include: nausea, vomiting, diaphoresis, and general malaise. Clinical and laboratory evidence of hepatic toxicity may not be apparent until 48 to 72 hours post-ingestion.
Oxycodone In case of overdose, priorities are the reestablishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures including oxygen and vasopressors in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support techniques. Opioid antagonists, such as naloxone, are specific antidotes to respiratory depression resulting from opioid overdose.
For clinically significant respiratory or circulatory depression secondary to oxycodone overdose, administer an opioid antagonist. Because the duration of opioid reversal is expected to be less than the duration of action of oxycodone in oxycodone and acetaminophen tablets, carefully monitor the patient until spontaneous respiration is reliably reestablished.
In an individual physically dependent on opioids, administration of the recommended usual dosage of the antagonist will precipitate an acute withdrawal syndrome.
The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered. If a decision is made to treat serious respiratory depression in the physically dependent patient, administration of the antagonist should be initiated with care and by titration with smaller than usual doses of the antagonist.
Acetaminophen Gastric decontamination with activated charcoal should be administered just prior to N-acetylcysteine NAC to decrease systemic absorption if acetaminophen ingestion is known or suspected to have occurred within a few hours of presentation. Serum acetaminophen levels should be obtained immediately if the patient presents 4 hours or more after ingestion to assess potential risk of hepatotoxicity; acetaminophen levels drawn less than 4 hours post-ingestion may be misleading.
To obtain the best possible outcome, NAC should be administered as soon as possible where impending or evolving liver injury is suspected.
Intravenous NAC may be administered when circumstances preclude oral administration. Vigorous supportive therapy is required in severe intoxication. Procedures to limit the continuing absorption of the drug must be readily performed since the hepatic injury is dose dependent and occurs early in the course of intoxication.
Initiate the dosing regimen for each patient individually, taking into account the patient's severity of pain, patient response, prior analgesic treatment experience, and risk factors for addiction, abuse, and misuse see WARNINGS. Monitor patients closely for respiratory depression, especially within the first 24 to 72 hours of initiating therapy and following dosage increases with oxycodone and acetaminophen tablets and adjust the dosage accordingly see WARNINGS.
Inform patients and caregivers about the various ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing regulations e. Consider prescribing naloxone when the patient has household members including children or other close contacts at risk for accidental ingestion or overdose.
Initiating Treatment with Oxycodone and Acetaminophen Tablets The usual adult dosage is one tablet every 6 hours as needed for pain. The total daily dose of acetaminophen should not exceed 4 grams. Conversion from Oxycodone and Acetaminophen to Extended-Release Oxycodone The relative bioavailability of oxycodone and acetaminophen tablets or oral solution compared to extended-release oxycodone is unknown, so conversion to extended-release oxycodone must be accompanied by close observation for signs of excessive sedation and respiratory depression.
Individually titrate oxycodone and acetaminophen tablets or oral solution to a dose that provides adequate analgesia and minimizes adverse reactions. Continually reevaluate patients receiving oxycodone and acetaminophen tablets or oral solution to assess the maintenance of pain control and the relative incidence of adverse reactions, as well as monitoring for the development of addiction, abuse, or misuse see WARNINGS.
If the level of pain increases after dosage stabilization, attempt to identify the source of increased pain before increasing the oxycodone and acetaminophen tablets or oral solution dosage. If unacceptable opioid-related adverse reactions are observed, consider reducing the dosage. Adjust the dosage to obtain an appropriate balance between management of pain and opioid-related adverse reactions.
Do not abruptly discontinue oxycodone and acetaminophen tablets or oral solution in patients who may be physically dependent on opioids. Rapid discontinuation of opioid analgesics in patients who are physically dependent on opioids has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide. Patients may also attempt to treat their pain or withdrawal symptoms with illicit opioids, such as heroin, and other substances.
When a decision has been made to decrease the dose or discontinue therapy in an opioid-dependent patient taking oxycodone and acetaminophen tablets or oral solution, there are a variety of factors that should be considered, including the dose of oxycodone and acetaminophen tablets or oral solution the patient has been taking, the duration of treatment, the type of pain being treated, and the physical and psychological attributes of the patient.
It is important to ensure ongoing care of the patient and to agree on an appropriate tapering schedule and follow-up plan so that patient and provider goals and expectations are clear and realistic. When opioid analgesics are being discontinued due to a suspected substance use disorder, evaluate and treat the patient, or refer for evaluation and treatment of the substance use disorder. Treatment should include evidence-based approaches, such as medication assisted treatment of opioid use disorder.
Complex patients with co-morbid pain and substance use disorders may benefit from referral to a specialist. There are no standard opioid tapering schedules that are suitable for all patients. Good clinical practice dictates a patient-specific plan to taper the dose of the opioid gradually. For patients on oxycodone and acetaminophen tablets who are physically opioid-dependent, initiate the taper by a small enough increment e.
Patients who have been taking opioids for briefer periods of time may tolerate a more rapid taper. It may be necessary to provide the patient with lower dosage strengths to accomplish a successful taper. Reassess the patient frequently to manage pain and withdrawal symptoms, should they emerge. Common withdrawal symptoms include restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis.
Other signs and symptoms also may develop, including irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate. If withdrawal symptoms arise, it may be necessary to pause the taper for a period of time or raise the dose of the opioid analgesic to the previous dose, and then proceed with a slower taper. In addition, monitor patients for any changes in mood, emergence of suicidal thoughts, or use of other substances.
