(ASA - oxycodone)



How does this medication work? What will it do for me?

This combination product contains two medications: oxycodone and acetylsalicylic acid (ASA). ASA belongs to the group of medications called analgesics (pain relievers), anti-inflammatories, and antipyretics (fever reducers). Oxycodone belongs to the group of medications called narcotic analgesics. This medication is used to relieve moderate to moderately severe pain, including conditions associated with fever or inflammation.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.

How should I use this medication?

The dosage varies according to each individual and can be affected by the severity of the pain as well as each person's response to the medication.

The recommended adult dose is 1 full-strength tablet every 6 hours as needed. The total amount of ASA taken during a 24-hour period should not exceed 4 g.

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

This medication may be habit-forming if taken for long periods of time. Do not stop taking this medication without talking with your doctor. If this medication is stopped suddenly, you may experience withdrawal symptoms such as anxiety, sweating, trouble sleeping, shakiness, nausea, tremors, diarrhea, or hallucinations. If you plan on stopping the medication, your doctor may want you to reduce the dose gradually to lessen the severity of withdrawal effects.

It is important to take this medication exactly as prescribed by your doctor. If your doctor has told you to take this medication on a regular basis and you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store this medication at room temperature, protect it from light and moisture, and keep it out of reach of children.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Abdominal conditions: Oxycodone may make the diagnosis of abdominal conditions more difficult, or it may worsen these conditions. If you have an abdominal condition such as inflammatory or obstructive bowel disease, acute cholecystitis, or pancreatitis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Bleeding disorders: ASA may increase bruising and bleeding from cuts that may take longer to stop. If you have a bleeding disorder or a history of bleeding problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Breathing: Oxycodone can suppress breathing. If you are at risk for breathing difficulties such as asthma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Dependence and withdrawal: This medication contains oxycodone. Physical dependence, psychological dependence, and abuse have occurred with the use of oxycodone. People with a history of past or current substance use problems may be at greater risk of developing abuse or addiction while taking this medication. Abuse is not a problem with people who require this medication for pain relief. If you abruptly stop taking this medication, you may experience withdrawal symptoms such as anxiety, sweating, trouble sleeping, shaking, pain, nausea, tremors, diarrhea, and hallucinations. If you have been taking this medication for a while, it should be stopped gradually as directed by your doctor.

Drowsiness/reduced alertness: This medication may cause drowsiness or dizziness, affecting your ability to drive or operate machinery. Avoid these and other potentially hazardous tasks until you have determined how this medication affects you.

Gout: ASA may cause or worsen attacks of gout. Symptoms of an acute gout attack include sudden pain, swelling, and stiffness in the affected joint, often the big toe. You may also experience a fever. If this is your first attack, seek medical attention as soon as possible. If you have had gout attacks before, follow your doctor's instructions for dealing with the attack.

Head injury: If you have a head injury or increased pressure in the head, you may have a higher risk of experiencing side effects (breathing problems) or worsening of your condition while taking this medication. Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Kidney function: Taking ASA - oxycodone for a long period of time may increase the risk of developing kidney disease. If you have kidney disease or reduced kidney function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver function: If you have liver disease or reduced liver function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Other medical conditions: If you are about to undergo surgery of the biliary tract, taking oxycodone may worsen your condition. Oxycodone will also worsen the effects of acute alcohol intoxication and delirium tremens.

As well, if you have low thyroid (hypothyroidism), Addison's disease, benign prostatic hypertrophy (enlarged prostate), urethral stricture, decreased function of the adrenal glands, or porphyria, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Seizures: This medication may cause seizures, especially when higher doses are used or when taken with other medications that may increase the risk of seizures such as:

  • cyclobenzaprine
  • monoamine oxidase inhibitors (MAOIs; e.g., phenelzine, tranylcypromine)
  • neuroleptics (e.g., haloperidol, quetiapine, olanzapine, risperidone)
  • opioids (e.g., morphine, codeine, oxycodone)
  • promethazine
  • selective serotonin reuptake inhibitors (SSRIs; e.g., paroxetine, fluoxetine, citalopram)
  • tricyclic antidepressants (TCAs; e.g., amitriptyline, imipramine)

The risk of seizures is also higher for people with epilepsy, a history of seizures, or who are at risk of seizures (e.g., people with head trauma).

Stomach problems: ASA may cause stomach problems such as ulcers or bleeding. If you have stomach problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Call your doctor immediately if you notice signs such as stomach or abdominal pain, black tarry stools, or vomiting blood. Using ASA at the same time as other anti-inflammatory medications increases the risk of stomach ulcers and bleeding.

Surgery: ASA can cause increased bleeding during surgery. Do not take ASA - oxycodone HCl for 1 to 2 weeks before any surgery, including dental surgery, unless otherwise directed by your doctor or dentist. If you are scheduled for surgery, let your doctor know that you are taking this medication.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.

Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking ASA - oxycodone, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children under 12 years of age. The use of ASA may be associated with the development of Reye's syndrome in children and teenagers who have illnesses accompanied by fever, especially influenza and chickenpox. ASA should not be given to or used by children or teenagers who have chickenpox or flu symptoms, unless a doctor is consulted.

Seniors: Seniors may be more susceptible to the harmful effects of ASA, possibly because of decreased kidney function.
