Additional dosage information:
Usual Adult Dose for Pain
Initial dose: 1 tablet (oxycodone 5 mg/aspirin 325 mg) orally every 6 hours as needed for pain
-Adjust dose to a dose that provides adequate analgesia while minimizing adverse reactions
Maximum dose: 12 tablets in 24 hours
Maximum Aspirin dose: 4 g in 24 hours
-Because of the risks of addiction, abuse and misuse, the lowest effective dose for the shortest duration consistent with individual patient treatment goals should be used.
-Monitor patients closely for respiratory depression within the first 24 to 72 hours of initiating therapy and following any increase in dose.
Use: For the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate.
Renal Dose Adjustments
Mild to moderate renal impairment: Use with caution
Severe renal impairment (CrCl less than 10 mL/min): Avoid use
Liver Dose Adjustments
Mild to moderate hepatic impairment: Use with caution
Severe hepatic impairment: Avoid use
Elderly, Cachectic, or Debilitated Patients: Use with caution generally starting at the low end of the dosing range, titrate dose slowly while monitoring closely for signs of CNS or respiratory depression.
Concomitant use of CYP450 3A4 inducers or inhibitors may require dose adjustments: Consult drug interactions
Discontinuation of Therapy in the Physically Dependent Patient:
-Taper dose gradually, by 25% to 50% every 2 to 4 days
-Monitor for signs and symptoms of withdrawal; if they occur, raise the dose to the previous level and taper more slowly
-Do not abruptly discontinue in the physically dependent patient
US BOXED WARNINGS: ADDICTION, ABUSE AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; NEONATAL OPIOID WITHDRAWAL SYNDROME; CYP450 3A4 INTERACTION; and RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS:
-Addiction, Abuse, and Misuse: This drug 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 and monitor all patients regularly for the development of these behaviors or conditions.
-Life-Threatening Respiratory Depression: Serious, life-threatening, or fatal respiratory depression may occur, especially during initiation or following a dose increase.
-Accidental Ingestion: Accidental ingestion of even 1 dose, especially by children, can result in a fatal overdose of oxycodone.
-Neonatal Opioid Withdrawal Syndrome: Prolonged use 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, the patient should be advised of the risk of neonatal opioid withdrawal syndrome and ensure appropriate treatment will be available.
-CYP450 3A4 Interaction: Concomitant use of CYP450 3A4 inhibitors may result in increased oxycodone plasma concentrations, which could increase or prolong adverse drug effects and may cause potentially fatal respiratory depression. In addition, discontinuation of a concomitantly used CYP450 3A4 inducer may result in increased oxycodone plasma concentrations. Monitor patients concomitantly receiving any CYP450 3A4 inhibitor or inducer.
-Concomitant Use with Benzodiazepines or Other CNS Depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Concomitant use should be reserved for use in patients for whom alternative treatment options are inadequate. If needed, limit dose and duration to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation.
Safety and efficacy have not been established in patients younger than 18 years.

Data not available
-Protect from light and moisture
-Use the lowest dose for the shortest duration consistent with individual patient treatment goals while keeping in mind the risks of addiction, abuse and misuse.
-Frequent communication between members of the healthcare team, patients, and their caregiver/family is important during periods of changing analgesic requirements; if the level of pain increases after dose stabilization, an attempt should be made to identify the source of increased pain before increasing the dose of pain medication.
-Monitor for respiratory depression, especially during initiation and following any increase in dose; close monitoring will be necessary in patients at increased risk and/or those receiving concomitant medications that increase the risk of respiratory depression
-Monitor for signs of hypotension
-Monitor for signs of GI ulceration, bleeding, and constipation
-Monitor for the development of behaviors indicative of addiction, abuse, or misuse
-Advise patients to store this drug safely out of the sight and reach of children; accidental use by a child is a medical emergency and can result in death.
-Patients should understand that this drug, even when taken as recommended can result in addiction, abuse, and misuse; instruct patients not to share their drug with others and protect their drug from theft or misuse.
-Patients should understand the risks of life-threatening respiratory depression, and be informed as to when this risk is greatest; patients and caregivers should be instructed to get emergency help right away if too much drug is taken or if breathing problems occur.
-Patients should be instructed to check with their healthcare provider before taking any new medications, herbal supplements, and over the counter products; patients should not drink alcohol while taking this drug.
