Addiction, Abuse, and MisuseOxycodone/acetaminophen exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk prior to prescribing oxycodone/acetaminophen, and monitor all patients regularly for the development of these behaviors or conditions .Opioid Analgesic Risk Evaluation and Mitigation Strategy (REMS)To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse and misuse, the Food and Drug Administration (FDA) has required a REMS for these products. Under the requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers. Healthcare providers are strongly encouraged to: complete a REMS-compliant education program, counsel patients and/or their caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products, emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacists, and consider other tools to improve patient, household, and community safety .Life-Threatening Respiratory DepressionSerious, life-threatening, or fatal respiratory depression may occur with use of oxycodone/acetaminophen. Monitor for respiratory depression, especially during initiation of oxycodone/acetaminophen or following a dose increase .Instruct patients to swallow oxycodone/acetaminophen ER tablets whole; crushing, chewing, or dissolving oxycodone/acetaminophen ER can cause rapid release and absorption of a potentially fatal dose of oxycodone Accidental IngestionAccidental ingestion of even one dose of oxycodone/acetaminophen, especially by children, can result in a fatal overdose of oxycodone .Neonatal Opioid Withdrawal SyndromeProlonged use of oxycodone/acetaminophen during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available .Cytochrome P450 3A4 InteractionThe concomitant use of Oxycodone/acetaminophen with all cytochrome P450 3A4 inhibitors may result in an increase in oxycodone plasma concentrations, which could increase or prolong adverse reactions and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used cytochrome P450 3A4 inducer may result in an increase in oxycodone plasma concentration. Monitor patients receiving Oxycodone/acetaminophen and any CYP3A4 inhibitor or inducer .HepatotoxicityAcetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4000 milligrams per day, and often involve more than one acetaminophen-containing product Risks from Concomitant Use with Benzodiazepines or Other CNS DepressantsReserve concomitant prescribing of oxycodone/acetaminophen and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients for signs and symptoms of respiratory depression and sedation .

Uses for oxycodone and acetaminophen
Oxycodone and acetaminophen combination is used to relieve pain severe enough to require opioid treatment and when other pain medicines did not work well enough or cannot be tolerated.
Acetaminophen is used to relieve pain and reduce fever in patients. It does not become habit-forming when taken for a long time. But acetaminophen may cause other unwanted effects when taken in large doses, including liver damage.
Oxycodone belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.
When oxycodone is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to occur when narcotics are used for this purpose. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.
Oxycodone and acetaminophen is available only with your doctor's prescription. Percocet® and Xartemis™ are available only under a restricted distribution program called the Opioid Analgesic REMS (Risk Evaluation and Mitigation Strategy) program.
Before using oxycodone and acetaminophen
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For oxycodone and acetaminophen, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to oxycodone and acetaminophen or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of oxycodone and acetaminophen combination in the pediatric population. Use of Xartemis™ is not recommended in children. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of oxycodone and acetaminophen combination extended-release tablet, solution, or tablet in the elderly. However, elderly patients are more likely to have age-related kidney, heart, lung, or liver problems, which may require caution and an adjustment in the dose for patients receiving oxycodone and acetaminophen.

Proper use of oxycodone and acetaminophen
Take oxycodone and acetaminophen only as directed by your doctor. Do not take more of it, do not take it more often, and do not take it for a longer time than your doctor ordered. This is especially important for elderly patients, who may be more sensitive to the effects of pain medicines. If too much of oxycodone and acetaminophen is taken for a long time, it may become habit-forming and cause mental or physical dependence. Also, large amounts of acetaminophen may cause liver damage if taken for a long time.
It is very important that you understand the rules of the Opioid Analgesic REMS program to prevent addiction, abuse, and misuse of oxycodone and acetaminophen combination. Oxycodone and acetaminophen should also come with a Medication Guide. Read and follow these instructions carefully. Read it again each time you refill your prescription in case there is new information. Ask your doctor if you have any questions.
You may take oxycodone and acetaminophen with or without food.

Precautions while using oxycodone and acetaminophen
It is very important that your doctor check your progress while you are taking oxycodone and acetaminophen, especially within the first 24 to 72 hours of treatment. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood and urine tests may be needed to check for unwanted effects.
It is against the law and dangerous for anyone else to use your medicine. Keep your unused medicine in a safe and secure place. People who are addicted to drugs might want to steal it.
Check with your doctor before using oxycodone and acetaminophen with alcohol or other medicines that affect the central nervous system (CNS). Oxycodone and acetaminophen will add to the effects of alcohol and other CNS depressants (medicines that can make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicine, other prescription pain medicine or narcotics, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics. Also, there may be a greater risk of liver damage if you drink three or more alcoholic beverages while you are taking acetaminophen. Do not drink alcoholic beverages.
If you think you or someone else may have taken an overdose of oxycodone and acetaminophen, get emergency help at once. Your doctor may also give naloxone to treat an overdose. Signs of an overdose include: extreme dizziness or weakness, slow heartbeat or breathing, seizures, trouble breathing, and cold, clammy skin. Call your doctor right away if you notice these symptoms.
Oxycodone and acetaminophen may be habit-forming. If you feel that the medicine is not working as well, do not use more than your prescribed dose. Call your doctor for instructions.
Do not use oxycodone and acetaminophen if you are using or have used an MAO inhibitor (eg, isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]) within the past 14 days. Using these medicine together may cause serious unwanted effects.
Oxycodone and acetaminophen may cause sleep-related breathing problems (eg, sleep apnea, sleep-related hypoxemia). Your doctor may decrease your dose if you have sleep apnea (stop breathing for short periods during sleep) while using oxycodone and acetaminophen.
Dizziness, lightheadedness, or fainting may occur when you get up suddenly from a lying or sitting position. Getting up slowly may help lessen this problem. Also, lying down for a while may relieve the dizziness or lightheadedness.
Oxycodone and acetaminophen may make you dizzy, drowsy, or lightheaded. Do not drive or do anything else that could be dangerous until you know how oxycodone and acetaminophen affects you.
Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, unusual tiredness or weakness, or yellow eyes or skin. These could be symptoms of a serious liver problem.
Serious skin reactions (eg, acute generalized exanthematous pustulosis, Stevens-Johnson syndrome, and toxic epidermal necrolysis) can occur with oxycodone and acetaminophen. Check with your doctor right away if you have blistering, peeling, or loosening of the skin, chills, cough, diarrhea, itching, joint or muscle pain red irritated eyes, red skin lesions, often with a purple center, sore throat, sores, ulcers, or white spots in the mouth or on the lips, or unusual tiredness or weakness while you are using oxycodone and acetaminophen.
Oxycodone and acetaminophen may cause serious allergic reactions, including anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth while you are using oxycodone and acetaminophen.
Using narcotics for a long time can cause severe constipation. To prevent this, your doctor may direct you to take laxatives, drink a lot of fluids, or increase the amount of fiber in your diet. Be sure to follow the directions carefully, because continuing constipation can lead to more serious problems.
If you have been using oxycodone and acetaminophen regularly for several weeks or longer, do not change your dose or suddenly stop using it without checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping it completely. This may help prevent worsening of your condition and reduce the possibility of withdrawal symptoms, including stomach cramps, anxiety, fever, irritability, nausea, restlessness, runny nose, sweating, tremors, or trouble with sleeping.
Using oxycodone and acetaminophen while you are pregnant may cause serious unwanted effects, including neonatal withdrawal syndrome in your newborn baby. Tell your doctor right away if you think you are pregnant or if you plan to become pregnant while using oxycodone and acetaminophen.
For nursing mothers:
- Talk to your doctor if you have any questions about taking oxycodone or about how oxycodone and acetaminophen may affect your baby.
- Call your doctor if you become extremely tired and have difficulty caring for your baby.
- Your baby should generally nurse every 2 to 3 hours and should not sleep for more than 4 hours at a time.
- Check with your doctor or hospital emergency room immediately if your baby shows signs of increased sleepiness (more than usual), difficulty breastfeeding, difficulty breathing, or limpness. These may be symptoms of an overdose and need immediate medical attention.
Before you have any medical tests, tell the medical doctor in charge that you are taking oxycodone and acetaminophen. The results of some tests may be affected by oxycodone and acetaminophen.
Check with your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or see or hear things that are not there. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you also take certain other medicines that affect serotonin levels in your body.
Using too much of oxycodone and acetaminophen may cause infertility (unable to have children). Talk with your doctor before using oxycodone and acetaminophen if you plan to have children.
Oxycodone and acetaminophen may cause adrenal gland problems. Check with your doctor right away if you have darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, mental depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.
