Endodan (Oral)

Oxycodone and aspirin combination is used to relieve pain that is severe enough to need opioid treatment, especially when other pain medicines haven't worked well enough or cannot be tolerated. Oxycodone is part of a group of medicines called narcotic analgesics (pain medicines). It works on the central nervous system (CNS) to relieve pain.

Aspirin is used to relieve pain and reduce fever in patients. Aspirin is part of a group of medicines known as salicylates and works 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, leading to mental or physical dependence. However, people with ongoing pain should not let the fear of dependence stop them from using narcotics to relieve their pain. Mental dependence (addiction) is not likely to happen when narcotics are used for this purpose. Physical dependence may cause withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be avoided by gradually lowering the dose over time before stopping treatment completely.

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

It is very important for your doctor to monitor your progress while you are taking this medicine, especially during the first 24 to 72 hours of treatment. This will help your doctor determine if the medicine is effective and if you should keep taking it. Blood and urine tests may be necessary to check for side effects.

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

Using this medicine during pregnancy, especially in the later stages, can lead to serious side effects, including neonatal withdrawal syndrome in your newborn. Inform your doctor immediately if you think you are pregnant or plan to become pregnant while using this medicine.

Check with your doctor before using Percodan® with alcohol or other medicines that affect the central nervous system (CNS). Combining alcohol or other CNS-affecting medicines with Percodan® may increase side effects, such as dizziness, poor concentration, drowsiness, unusual dreams, and sleep issues. Some examples of CNS-affecting medicines include antihistamines, allergy or cold medications, sedatives, tranquilizers, sleeping aids, depression medications, anxiety medications, prescription pain medicines or narcotics, ADHD medications, seizure medications or barbiturates, muscle relaxants, and anesthetics, including some dental anesthetics.

If you suspect an overdose of this medicine, seek emergency help immediately. Your doctor may administer naloxone to reverse an overdose. Signs of an overdose include extreme dizziness or weakness, slow heartbeat or breathing, seizures, difficulty breathing, and cold, clammy skin. Contact your doctor right away if you notice these symptoms.

This medicine may cause sleep-related breathing problems (e.g., sleep apnea, sleep-related hypoxemia). Your doctor may lower your dose if you have sleep apnea while using this medicine.

Do not change your dose or stop taking this medicine suddenly without consulting your doctor first. Your doctor may advise you to gradually reduce your dosage before stopping completely to lessen the risk of withdrawal symptoms, which may include restlessness, chills, muscle pain, runny nose, sweating, tearing of the eyes, or yawning.

Make sure any doctor or dentist treating you is aware that you are using this medicine. You may need to stop using this medicine several days before any surgery or medical tests.

This medicine may be habit-forming. If you feel the medicine is becoming less effective, do not exceed your prescribed dose. Contact your doctor for guidance.

Dizziness, lightheadedness, or fainting may occur when you stand up suddenly from a lying or sitting position. Getting up slowly may help reduce this issue. Additionally, lying down for a while may alleviate dizziness or lightheadedness. If this problem persists or worsens, consult your doctor immediately.

This medicine may cause dizziness, drowsiness, or lightheadedness. Avoid driving or engaging in any activities that could be dangerous until you understand how this medicine affects you.

This medicine may lead to bleeding in your stomach or bowels without warning signs. This risk is higher if you have had a stomach ulcer, drink alcohol regularly, are over 60 years old, are in poor health, or are taking certain other medicines (e.g., NSAIDs).

This medicine may cause issues with the adrenal glands. Contact your doctor immediately if you experience darkening of the skin, diarrhea, dizziness, fainting, loss of appetite, depression, nausea, skin rash, unusual tiredness or weakness, or vomiting.

This medicine may result in bleeding in your stomach or bowels. Contact your doctor immediately if you have bloody or black, tarry stools, heartburn, nausea, vomiting, stomach pain, or vomit that looks like coffee grounds.

This medicine can cause a serious allergic reaction known as anaphylaxis, which can be life-threatening and requires immediate medical attention. Call your doctor right away if you experience a rash, itching, hoarseness, difficulty breathing, trouble swallowing, or swelling in your hands, face, or mouth while using this medicine.

Contact 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 in the mouth or on the lips, swollen glands, difficulty breathing, unusual bleeding or bruising, or unusual tiredness or weakness. These may indicate a serious skin reaction, including drug reaction with eosinophilia and systemic symptoms (DRESS).

For nursing mothers:

• Discuss with your doctor if you have any questions about taking oxycodone or how this medicine might affect your baby.
• Call your doctor if you feel extremely tired and have trouble caring for your baby.
• Your baby should typically nurse every 2 to 3 hours and should not sleep for more than 4 hours at a time.
• Contact your doctor or the hospital emergency room immediately if your baby shows signs of increased sleepiness (more than usual), difficulty breastfeeding, trouble breathing, or limpness. These may be signs of an overdose and require urgent medical attention.

Contact your doctor right away if you have anxiety, restlessness, a fast heartbeat, fever, sweating, muscle spasms, twitching, nausea, vomiting, diarrhea, or experience hallucinations. These may be symptoms of a serious condition called serotonin syndrome. Your risk may be higher if you are also taking certain other medicines that influence serotonin levels in your body.

Using too much of this medicine may lead to infertility (inability to have children). Speak with your doctor before using this medicine if you plan to have children.

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

In deciding to use a drug, the chances of taking the drug must be weighed against the beneficial it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Inform your physician if you have ever had any unusual or allergic reaction to this medication or any other drugs. As well inform 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 advised. 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. Nevertheless, 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.

Breast Feeding

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 using this medicine 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.
