Endodan (Oral)

Generic Name: oxycodone and aspirin (Oral route)

AS-pir-in, ox-i-KOE-done hye-droe-KLOR-ide

Oral route(Tablet)

Oxycodone hydrochloride/aspirin has the potential for addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk before prescribing, and monitor for development of these behaviors or conditions. Serious, life-threatening, or fatal respiratory depression may occur. Monitor closely, especially upon initiation or following a dose increase. Accidental ingestion of oxycodone hydrochloride/aspirin, especially in children, can result in fatal overdose of oxycodone hydrochloride. Prolonged use of oxycodone hydrochloride/aspirin during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated. 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. Concomitant use or discontinuation of concomitantly used cytochrome P450 3A4 inhibitors and inducers may affect the plasma levels of oxycodone and lead to fatal respiratory depression, profound sedation, opioid toxicity, and/or opioid withdrawal. Monitor patients carefully when oxycodone hydrochloride/aspirin and cytochrome P450 3A4 inhibitors and inducers are concurrently used. Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for patients with inadequate alternative treatment options. Limit dosages and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation .

Uses For Endodan

Oxycodone and aspirin combination is used to relieve moderate to moderately severe pain. 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.

This medicine is available only with your doctor's prescription.

Before Using Endodan

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 this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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.

Breast Feeding

Aspirin

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.

Oxycodone

Studies in women breastfeeding have demonstrated harmful infant effects. An alternative to this medication should be prescribed or you should stop breastfeeding while using this medicine.
