# Oxycodone and aspirin (Oral)

Medically reviewed by Drugs.com. Last updated on Sep 13, 2022.

Oral route(Tablet)

Addiction, Abuse, and MisuseOxycodone hydrochloride/aspirin 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 hydrochloride/aspirin, 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 hydrochloride/aspirin. Monitor for respiratory depression, especially during initiation of oxycodone hydrochloride/aspirin or following a dose increase.Accidental IngestionAccidental ingestion of even one dose of oxycodone hydrochloride/aspirin, especially by children, can result in a fatal overdose of oxycodone hydrochloride.Neonatal Opioid Withdrawal SyndromeProlonged use of oxycodone hydrochloride/aspirin 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 hydrochloride/aspirin 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 hydrochloride/aspirin and any CYP3A4 inhibitor or inducer.Risks from Concomitant Use with Benzodiazepines or Other CNS DepressantsReserve concomitant prescribing of oxycodone hydrochloride/aspirin 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 aspirin

Oxycodone and aspirin 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. Oxycodone belongs to the group of medicines called narcotic analgesics (pain medicines). It acts on the central nervous system (CNS) to relieve pain.

Aspirin is used to relieve pain and reduce fever in patients. Aspirin belongs to the group of medicines known as salicylates and acts on the immune system to reduce inflammation. It is also known as an antiinflammatory analgesic.

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 aspirin is available only under a restricted distribution program called the Opioid Analgesic REMS (Risk Evaluation and Mitigation Strategy) program.

## Before using oxycodone and aspirin

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 aspirin, the following should be considered:

### Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to oxycodone and aspirin 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.

### Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of oxycodone and aspirin combination in the pediatric population. Because of aspirin's toxicity, use in children is not recommended. Do not give aspirin to a child who has chickenpox or flu symptoms, unless approved by a doctor. Aspirin can cause a life-threatening reaction called Reye syndrome.

### Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of oxycodone and aspirin combination in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or lung problems, which may require caution and an adjustment in the dose for patients receiving oxycodone and aspirin combination.

### Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

### Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking oxycodone and aspirin, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.

Using oxycodone and aspirin with any of the following medicines is not recommended. Your doctor may decide not to treat you with this medication or change some of the other medicines you take.

## Proper use of oxycodone and aspirin

Take oxycodone and aspirin 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 aspirin is taken for a long time, it may become habit-forming (causing mental or physical dependence).

It is very important that you understand the rules of the Opioid Analgesic REMS program to prevent addiction, abuse, and misuse of oxycodone and aspirin combination. Oxycodone and aspirin should come with a Medication Guide. Read and follow the instructions carefully. 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.

### Dosing

The dose of oxycodone and aspirin will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of oxycodone and aspirin. If your dose is different, do not change it unless your doctor tells you to do so.

The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

- For oral dosage form (tablets):
  - For moderate to moderately severe pain:
    - Adults—At first, 1 tablet every 6 hours as needed. Your doctor may adjust your dose as needed. However, the dose is usually not more than 12 tablets per day.
    - Children—Use and dose must be determined by your doctor.

### Missed dose

If you miss a dose of oxycodone and aspirin, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

### Storage

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

Ask your healthcare professional how you should dispose of any medicine you do not use.

Store the medicine in a safe and secure place. Drop off any unused narcotic medicine at a drug take-back location right away. If you do not have a drug take-back location near you, flush any unused narcotic medicine down the toilet. Check your local drug store and clinics for take-back locations. You can also check the DEA web site for locations.

Detailed Aspirin / oxycodone dosage information

## Precautions while using oxycodone and aspirin

It is very important that your doctor check your progress while you are using oxycodone and aspirin, 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.

Do not use oxycodone and aspirin if you are using or have used an MAO inhibitor (MAOI) such as isocarboxazid [Marplan®], linezolid [Zyvox®], phenelzine [Nardil®], selegiline [Eldepryl®], tranylcypromine [Parnate®]) within the past 14 days.

Using oxycodone and aspirin while you are pregnant, especially during the later part of pregnancy 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 aspirin.

Check with your doctor before using Percodan® with alcohol or other medicines that affect the central nervous system (CNS). The use of alcohol or other medicines that affect the CNS with Percodan® may worsen the side effects of oxycodone and aspirin, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.

If you think you or someone else may have taken an overdose of oxycodone and aspirin, 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 aspirin 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 aspirin.

Do not change your dose or suddenly stop taking oxycodone and aspirin without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are using before stopping completely. This will decrease your chance of having withdrawal symptoms, including restlessness, chills, muscle pain, runny nose, sweating, tearing of the eyes, or yawning.

Make sure any doctor or dentist who treats you knows that you are using oxycodone and aspirin. You may need to stop using oxycodone and aspirin several days before you have surgery or medical tests.

Oxycodone and aspirin 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.

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. If this problem continues or gets worse, check with your doctor right away.

Oxycodone and aspirin may make you dizzy, drowsy, or lightheaded. Do not drive or do anything else that could be dangerous until you know how oxycodone and aspirin affects you.

Oxycodone and aspirin may cause bleeding in your stomach or bowels. This problem can happen without warning signs. This is more likely if you have had a stomach ulcer in the past, if you drink alcohol regularly, if you are over 60 years of age, are in poor health, or are using certain other medicines (eg, NSAIDs).

Oxycodone and aspirin 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.

Oxycodone and aspirin may cause bleeding in your stomach or bowels. Check with your doctor right away if you have bloody or black, tarry stools, heartburn, nausea, vomiting, stomach pain, or vomiting of blood or material that looks like coffee grounds.

Oxycodone and aspirin may cause a serious allergic reaction called 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 aspirin.

Check with your doctor right away if you have black, tarry stools, chest pain, chills, cough, fever, painful or difficult urination, sore throat, sores, ulcers, or white spots on the lips or in the mouth, swollen glands, trouble breathing, unusual bleeding or bruising, or unusual tiredness or weakness. These may be symptoms of serious skin reaction including drug reaction with eosinophilia and systemic symptoms (DRESS).

For nursing mothers:

- Talk to your doctor if you have any questions about taking oxycodone or about how oxycodone and aspirin 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.

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 aspirin may cause infertility (unable to have children). Talk with your doctor before using oxycodone and aspirin if you plan to have children.

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
