Ensure accuracy when prescribing, dispensing, and administering oxycodone/acetaminophen oral solution. Dosing errors due to confusion between mg and mL and other solutions of different concentrations can result in accidental overdose and death.
Oxycodone/acetaminophen 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/acetaminophen, and monitor all patients regularly for the development of these behaviors and conditions.
To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, the 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 health care providers. Health care providers are strongly encouraged to complete a REMS-compliant education program and 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 pharmacist; and consider other tools to improve patient, household, and community safety.
Serious, life-threatening, or fatal respiratory depression may occur with use of oxycodone/acetaminophen. Monitor for respiratory depression, especially during initiation of oxycodone/acetaminophen or following a dose increase.
Accidental ingestion of oxycodone/acetaminophen, especially in children, can result in a fatal overdose of oxycodone.
Prolonged use of oxycodone/acetaminophen during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized 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.
The concomitant use of oxycodone/acetaminophen 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/acetaminophen and any CYP3A4 inhibitor or inducer.
Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4 g/day in adults, and often involve more than 1 acetaminophen-containing product.
Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of oxycodone/acetaminophen 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.
Note: Initial dose is based on the oxycodone content; however, the maximum daily dose is based on the acetaminophen content.
Pain management: Doses should be titrated to appropriate analgesic effects.
Oral: Initial dose, based on oxycodone content: 5 mg (moderate pain) or 10 to 20 mg (severe pain) (APS 2008) or 2.5 to 10 mg (manufacturer's labeling). Doses typically given every 4 to 6 hours as needed. Do not exceed acetaminophen 4 g/day (APS 2008).
Discontinuation of therapy: When discontinuing chronic opioid therapy, the dose should be gradually tapered down. An optimal universal tapering schedule for all patients has not been established (CDC [Dowell 2016]). Proposed schedules range from slow (eg, 10% reductions per week) to rapid (eg, 25% to 50% reduction every few days) (CDC 2015). Tapering schedules should be individualized to minimize opioid withdrawal while considering patient-specific goals and concerns as well as the pharmacokinetics of the opioid being tapered. An even slower taper may be appropriate in patients who have been receiving opioids for a long duration (eg, years), particularly in the final stage of tapering, whereas more rapid tapers may be appropriate in patients experiencing severe adverse events (CDC [Dowell 2016]). Monitor carefully for signs/symptoms of withdrawal. If the patient displays withdrawal symptoms, consider slowing the taper schedule; alterations may include increasing the interval between dose reductions, decreasing amount of daily dose reduction, pausing the taper and restarting when the patient is ready, and/or coadministration of an alpha-2 agonist (eg, clonidine) to blunt withdrawal symptoms (Berna 2015; CDC [Dowell 2016]). Continue to offer nonopioid analgesics as needed for pain management during the taper; consider nonopioid adjunctive treatments for withdrawal symptoms (eg, GI complaints, muscle spasm) as needed (Berna 2015; Sevarino 2018).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no dosage adjustments provided in the manufacturer’s labeling. Use with caution and initiate at the low end of the dosing range; titrate carefully and monitor closely.

(For additional information see "Oxycodone and acetaminophen (paracetamol): Pediatric drug information")
Note: Doses based on total oxycodone content; titrate dose to appropriate analgesic effects. All sources of acetaminophen (eg, prescription, OTC, combination products) should be considered when evaluating a patient's maximum daily acetaminophen dose. To lower the risk for hepatotoxicity, limit daily dose to ≤75 mg/kg/day (maximum of 5 daily doses), not to exceed 4,000 mg/day; while recommended doses are generally considered safe, hepatotoxicity has been reported (rarely) even with doses below recommendations (AAP [Sullivan 2011]; Heard 2014; Lavonas 2010).
Analgesic: Limited data available: Infants ≥6 months, Children, and Adolescents:
Patient weight:
<50 kg: Oral: Usual initial dose: Oxycodone 0.1 to 0.2 mg/kg/dose; doses typically given every 4 to 6 hours as needed; manufacturer's labeling recommends every 6 hours in adults (Berde 2002; Kliegman 2020; Thigpen 2019).
≥50 kg: Oral: Usual initial dose: Oxycodone 5 to 10 mg every 4 to 6 hours; manufacturer's labeling recommends every 6 hours in adults (Berde 2002; Thigpen 2019).
Discontinuation of therapy: Do not abruptly discontinue therapy in patients who are physically dependent; dose should be gradually tapered to avoid withdrawal. An optimal tapering schedule has not been established. The taper should be individualized to minimize withdrawal and should be based on total daily opioid dose, length of opioid exposure, and patient response. Monitor patients for signs and symptoms of opioid withdrawal (D'Souza 2018).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
There are no pediatric-specific recommendations. In general, oxycodone clearance may be decreased in patients with renal impairment. Based on experience in adult patients, use with caution and initiate at the low end of the dosing range; titrate carefully and monitor closely.
There are no pediatric-specific recommendations; based on experience in adult patients, use with caution and initiate at the low end of the dosing range; titrate carefully and monitor closely. For acetaminophen, limited, low-dose therapy is usually well-tolerated in hepatic disease/cirrhosis; however, cases of hepatotoxicity at daily acetaminophen dosages <4,000 mg/day in adults have been reported. Avoid chronic use in hepatic impairment. See individual monographs.
Refer to adult dosing. Use with caution and consider initiation at the low end of the dosing range; titrate slowly.
Severe pain: Elderly >70 years (off-label dosing): Consider decreasing the initial dose (based on oxycodone content) by 25% to 50%, then titrating the dose upward or downward as needed; monitor frequently during titration. Do not exceed acetaminophen 4 g/day (APS 2008).

Additional product-specific contraindications: Endocet, Primlev: Hypercarbia
Documentation of allergenic cross-reactivity for opioids is limited. However, because of similarities in chemical structure and/or pharmacologic actions, the possibility of cross-sensitivity cannot be ruled out with certainty.
Canadian labeling: Additional contraindications (not in US labeling): Severe hepatic insufficiency or active liver disease; suspected surgical abdomen (eg, acute appendicitis or pancreatitis); mild pain that can be managed with other pain medications; chronic obstructive airway; cor pulmonale; acute alcoholism, delirium tremens, or convulsive disorders; severe CNS depression, increased cerebrospinal or intracranial pressure, or head injury; concurrent use with or within 14 days following MAOI therapy; pregnant women or during labor and delivery; breastfeeding
Concerns related to adverse effects:
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery, driving).
• Constipation: Oxycodone may cause constipation, which may be problematic in patients with unstable angina and patients post-myocardial infarction (MI). Consider preventive measures (eg, stool softener, increased fiber) to reduce the potential for constipation.
• Hepatotoxicity: [US Boxed Warning]: Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed 4 g/day in adults, and often involve more than 1 acetaminophen-containing product. Risk is increased with alcohol use, preexisting liver disease, and intake of more than 1 source of acetaminophen-containing medications. Chronic daily dosing in adults has also resulted in liver damage in some patients.
• Hypersensitivity/anaphylactic reactions: Hypersensitivity and anaphylactic reactions have been reported with acetaminophen use; discontinue immediately if symptoms of allergic or hypersensitivity reactions occur.
• Hypotension: May cause severe hypotension (including orthostatic hypotension and syncope); use with caution in patients with hypovolemia, cardiovascular disease (including acute MI), or drugs that may exaggerate hypotensive effects (including phenothiazines or general anesthetics). Monitor for symptoms of hypotension following initiation or dose titration. Avoid use in patients with circulatory shock.
• Phenanthrene hypersensitivity: Use oxycodone with caution in patients with hypersensitivity reactions to other phenanthrene-derivative opioid agonists (codeine, hydrocodone, hydromorphone, levorphanol, oxymorphone).
• Respiratory depression: [US Boxed Warning]: Serious, life-threatening, or fatal respiratory depression may occur. Monitor closely for respiratory depression, especially during initiation or dose escalation. Carbon dioxide retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. Patients and caregivers should be educated on how to recognize respiratory depression and the importance of getting emergency assistance immediately (eg, calling 911) in the event of known or suspected overdose.
• Skin reactions: Serious and potentially fatal skin reactions, including acute generalized exanthematous pustulosis, Stevens-Johnson syndrome, and toxic epidermal necrolysis, have occurred rarely with acetaminophen use. Discontinue therapy at the first appearance of skin rash.
Disease-related concerns:
• Abdominal conditions: May obscure diagnosis or clinical course of patients with acute abdominal conditions.
• Adrenocortical insufficiency: Use with caution in patients with adrenal insufficiency, including Addison disease. Long-term opioid use may cause secondary hypogonadism, which may lead to mood disorders and osteoporosis (Brennan 2013).
• Biliary tract impairment: Use with caution in patients with biliary tract dysfunction, including acute pancreatitis; opioids may cause constriction of sphincter of Oddi.
• CNS depression/coma: Avoid use in patients with CNS depression or coma as these patients are susceptible to intracranial effects of CO2 retention.
• Delirium tremens: Use with caution in patients with delirium tremens.
• G6PD deficiency: Use acetaminophen with caution in patients with known G6PD deficiency.
• Head trauma: Use with extreme caution in patients with head injury, intracranial lesions, or elevated intracranial pressure (ICP); exaggerated elevation of ICP may occur.
• Hepatic impairment: Use with caution in patients with hepatic impairment. Use with caution in patients with alcoholic liver disease; consuming ≥3 alcoholic drinks/day may increase the risk of liver damage.
• Mental health conditions: Use opioids with caution for chronic pain in patients with mental health conditions (eg, depression, anxiety disorders, post-traumatic stress disorder) due to increased risk for opioid use disorder and overdose; more frequent monitoring is recommended (Dowell [CDC 2016]).
• Obesity: Use with caution in patients who are morbidly obese (APS 2008).
• Prostatic hyperplasia/urinary stricture: Use with caution in patients with prostatic hyperplasia and/or urinary stricture.
• Psychosis: Use with caution in patients with toxic psychosis.
• Renal impairment: Use with caution in patients with renal impairment.
• Respiratory disease: Use with caution and monitor for respiratory depression in patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or preexisting respiratory depression, particularly when initiating and titrating therapy; critical respiratory depression may occur, even at therapeutic dosages. Consider the use of alternative nonopioid analgesics in these patients.
• Seizures: Use with caution in patients with a history of seizure disorders; may cause or exacerbate seizures.
• Sleep-related disorders: Opioid use increases the risk for sleep-related disorders (eg, central sleep apnea [CSA], hypoxemia) in a dose-dependent fashion. Use with caution for chronic pain and titrate dosage cautiously in patients with risk factors for sleep-disordered breathing (eg, heart failure, obesity). Consider dose reduction in patients presenting with CSA. Avoid opioids in patients with moderate to severe sleep-disordered breathing (Dowell [CDC 2016]).
• Thyroid dysfunction: Use with caution in patients with thyroid dysfunction.
Concurrent drug therapy issues:
• Benzodiazepines or other CNS depressants: [US Boxed Warning]: Concomitant use of opioids with benzodiazepines or other CNS depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing of oxycodone/acetaminophen and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate. Limit dosage and durations to the minimum required and follow patients for signs and symptoms of respiratory depression and sedation. Consider prescribing naloxone for emergency treatment of opioid overdose in patients taking benzodiazepines or other CNS depressants concomitantly with opioids.
• Cytochrome P450 3A4 interactions: [US Boxed Warning]: The concomitant use of oxycodone/acetaminophen 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/acetaminophen and any CYP3A4 inhibitor or inducer.
Special populations:
• Cachectic or debilitated patients: Use oxycodone with caution in cachectic or debilitated patients; there is a greater potential for respiratory depression, even at therapeutic dosages. Consider the use of alternative nonopioid analgesics in these patients.
• Older adult: Use with caution in older adult patients; may be more sensitive to adverse effects, such as respiratory depression. Oxycodone clearance may also be slightly reduced in older adult patients. Dosage adjustments may be necessary. Use opioids for chronic pain with caution in this age group; monitor closely due to an increased potential for risks, including certain risks such as falls/fracture, cognitive impairment, and constipation (Dowell [CDC 2016]). Consider the use of alternative nonopioid analgesics in these patients.
• Neonates: Neonatal withdrawal syndrome: [US Boxed Warning]: Prolonged use of opioids during pregnancy can cause neonatal withdrawal syndrome in the newborn, which may be life-threatening if not recognized and treated 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. Signs and symptoms include irritability, hyperactivity and abnormal sleep pattern, high-pitched cry, tremor, vomiting, diarrhea, and failure to gain weight. Onset, duration, and severity depend on the drug used, duration of use, maternal dose, and rate of drug elimination by the newborn.
Dosage form specific issues:
• Benzyl alcohol and derivatives: Some dosage forms may contain sodium benzoate/benzoic acid; benzoic acid (benzoate) is a metabolite of benzyl alcohol; large amounts of benzyl alcohol (≥99 mg/kg/day) have been associated with a potentially fatal toxicity ("gasping syndrome") in neonates; the "gasping syndrome" consists of metabolic acidosis, respiratory distress, gasping respirations, CNS dysfunction (including convulsions, intracranial hemorrhage), hypotension, and cardiovascular collapse (AAP ["Inactive" 1997]; CDC 1982); some data suggest that benzoate displaces bilirubin from protein binding sites (Ahlfors 2001); avoid or use dosage forms containing benzyl alcohol derivative with caution in neonates. See manufacturer's labeling.
• Propylene glycol: Some dosage forms may contain propylene glycol; large amounts are potentially toxic and have been associated with hyperosmolality, lactic acidosis, seizures, and respiratory depression; use caution (AAP 1997; Zar 2007).
• Sulfites: Some preparations contain sulfites, which may cause allergic reactions.
Other warnings/precautions:
• Abrupt discontinuation/withdrawal: Abrupt discontinuation in patients who are physically dependent on opioids has been associated with serious withdrawal symptoms, uncontrolled pain, attempts to find other opioids (including illicit), and suicide. Use a collaborative, patient-specific taper schedule that minimizes the risk of withdrawal, considering factors such as current opioid dose, duration of use, type of pain, and physical and psychological factors. Monitor pain control, withdrawal symptoms, mood changes, suicidal ideation, and for use of other substances; provide care as needed. Concurrent use of mixed agonist/antagonist analgesics (eg, pentazocine, nalbuphine, butorphanol) or partial agonist (eg, buprenorphine) analgesics may also precipitate withdrawal symptoms and/or reduced analgesic efficacy in patients following prolonged therapy with mu opioid agonists.
• Abuse/misuse/diversion: [US Boxed Warning]: Use 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/acetaminophen, and monitor all patients regularly for the development of these behaviors or conditions. Use with caution in patients with a history of drug abuse or acute alcoholism; potential for drug dependency exists. Other factors associated with increased risk for misuse include younger age, concomitant depression (major), and psychotropic medication use. Consider offering naloxone prescriptions in patients with factors associated with an increased risk for overdose, such as history of overdose or substance use disorder, higher opioid dosages (≥50 morphine milligram equivalents [MME]/day orally), and concomitant benzodiazepine use (Dowell [CDC 2016]).
• Accidental ingestion: [US Boxed Warning]: Accidental ingestion of oxycodone/acetaminophen, especially in children, can result in a fatal overdose of oxycodone.
• Appropriate use: Chronic pain (outside of end-of-life or palliative care, active cancer treatment, sickle cell disease, or medication-based opioid use disorder treatment) in outpatient setting in adults: Opioids should not be used as first-line therapy for chronic pain management (pain >3-month duration or beyond time of normal tissue healing) due to limited short-term benefits, undetermined long-term benefits, and association with serious risks (eg, overdose, MI, auto accidents, risk of developing opioid use disorder). Preferred management includes nonpharmacologic therapy and nonopioid therapy (eg, nonsteroidal anti-inflammatory drugs, acetaminophen, certain antiseizure medications and antidepressants). If opioid therapy is initiated, it should be combined with nonpharmacologic and nonopioid therapy, as appropriate. Prior to initiation, known risks of opioid therapy should be discussed and realistic treatment goals for pain/function should be established, including consideration for discontinuation if benefits do not outweigh risks. Therapy should be continued only if clinically meaningful improvement in pain/function outweighs risks. Therapy should be initiated at the lowest effective dosage using IR opioids (instead of ER/long-acting opioids). Risk associated with use increases with higher opioid dosages. Risks and benefits should be re-evaluated when increasing dosage to ≥50 MME/day orally; dosages ≥90 MME/day orally should be avoided unless carefully justified (Dowell [CDC 2016]).
• Dosage limit: Limit acetaminophen dose from all sources (prescription and OTC) to <4 g/day in adults. Do not use oxycodone/acetaminophen concomitantly with other acetaminophen-containing products.
• Naloxone access: Discuss the availability of naloxone with all patients who are prescribed opioid analgesics, as well as their caregivers, and consider prescribing it to patients who are at increased risk of opioid overdose. These include patients who are also taking benzodiazepines or other CNS depressants, have an opioid use disorder (OUD) (current or history of), or have experienced a previous opioid overdose. Additionally, health care providers should consider prescribing naloxone to patients prescribed medications to treat OUD; patients at risk of opioid overdose even if they are not taking an opioid analgesic or medication to treat OUD; and patients taking opioids, including methadone or buprenorphine for OUD, if they have household members, including children, or other close contacts at risk for accidental ingestion or opioid overdose. Inform patients and caregivers on options for obtaining naloxone (eg, by prescription, directly from a pharmacist, a community-based program) as permitted by state dispensing and prescribing guidelines. Educate patients and caregivers on how to recognize respiratory depression, proper administration of naloxone, and getting emergency help.
• Optimal regimen: An opioid-containing analgesic regimen should be tailored to each patient's needs and based upon the type of pain being treated (acute versus chronic), the route of administration, degree of tolerance for opioids (naive versus chronic user), age, weight, and medical condition. The optimal analgesic dose varies widely among patients; doses should be titrated to pain relief/prevention.
• REMS program: [US Boxed Warning]: To ensure that the benefits of opioid analgesics outweigh the risks of addiction, abuse, and misuse, a REMS is required. Drug companies with approved opioid analgesic products must make REMS-compliant education programs available to health care providers. Health care providers are 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 pharmacist; and consider other tools to improve patient, household, and community safety.
• Risk of medication errors: [US Boxed Warning]: Ensure accuracy when prescribing, dispensing, and administering oxycodone/acetaminophen oral solution. Dosing errors due to confusion between mg and mL and other solutions of different concentrations can result in accidental overdose and death. Use calibrated measuring device.
• Surgery: Opioids decrease bowel motility; monitor for decreased bowel motility in postop patients receiving opioids. Use with caution in the perioperative setting; individualize treatment when transitioning from parenteral to oral analgesics.
Hepatoxicity has been reported in patients using acetaminophen. In pediatric patients, this is most commonly associated with supratherapeutic dosing, more frequent administration than recommended, and use of multiple acetaminophen-containing products; however, hepatotoxicity has been rarely reported with recommended dosages (AAP [Sullivan 2011]; Heard 2014). All sources of acetaminophen (eg, prescription, OTC, combination) should be considered when evaluating a patient's maximum daily dose. To lower the risk for hepatotoxicity, the maximum daily acetaminophen dose should be limited to ≤75 mg/kg/day (maximum of 5 daily doses), not to exceed 4,000 mg/day (AAP [Sullivan 2011]; Heard 2014; Krenzelok 2012; Lavonas 2010). Acetaminophen avoidance or a lower total daily dose (2,000 to 3,000 mg/day) has been suggested for adults with increased risk for acetaminophen hepatotoxicity (eg, malnutrition, certain liver diseases, use of drugs that interact with acetaminophen metabolism); similar data are unavailable in pediatric patients (Hayward 2016; Larson 2007; Worriax 2007).
Infants born to women physically dependent on opioids will also be physically dependent and may experience respiratory difficulties or opioid withdrawal symptoms (neonatal abstinence syndrome [NAS]). Onset, duration, and severity of NAS depend upon the drug used (maternal), duration of use, maternal dose, and rate of drug elimination by the newborn. Symptoms of opioid withdrawal may include excessive crying, diarrhea, fever, hyper-reflexia, irritability, tremors, or vomiting or failure to gain weight. Opioid withdrawal syndrome in the neonate may be life-threatening and should be promptly treated.
Some dosage forms may contain propylene glycol; in neonates, large amounts of propylene glycol delivered orally, intravenously (eg, >3,000 mg/day), or topically have been associated with potentially fatal toxicities which can include metabolic acidosis, seizures, renal failure, and CNS depression; toxicities have also been reported in children and adults including hyperosmolality, lactic acidosis, seizures, and respiratory depression; use caution (AAP 1997; Shehab 2009).

Long-term opioid use may cause secondary hypogonadism, which may lead to sexual dysfunction or infertility in men and women (Brennan 2013).
[US Boxed Warning]: Prolonged use of opioids 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 appropriate treatment will be available. Refer to individual monographs for additional information.
Oxycodone and acetaminophen are present in breast milk. Due to the potential for serious adverse reactions in the breastfeeding infant, breastfeeding is not recommended by the manufacturer. Refer to individual monographs.

Alternate recommendations: Chronic pain (long-term therapy outside of end-of-life or palliative care, active cancer treatment, sickle cell disease, or medication-based opioid use disorder treatment): Evaluate benefits/risks of opioid therapy within 1 to 4 weeks of treatment initiation and with dose increases. Re-evaluate benefits/risks every 3 months during therapy or more frequently in patients at increased risk of overdose or opioid use disorder. Urine drug testing is recommended prior to initiation and re-checking should be considered at least yearly (includes controlled prescription medications and illicit drugs of abuse). State prescription drug monitoring program (PDMP) data should be reviewed by clinicians prior to initiation and periodically during therapy (frequency ranging from every prescription to every 3 months) (Dowell [CDC 2016]).
Oxycodone: Binds to opiate receptors in the CNS, causing inhibition of ascending pain pathways, altering the perception of and response to pain; produces generalized CNS depression.
Acetaminophen: Although not fully elucidated, the analgesic effects are believed to be due to activation of descending serotonergic inhibitory pathways in the CNS. Interactions with other nociceptive systems may be involved as well (Smith 2009). Antipyresis is produced from inhibition of the hypothalamic heat-regulating center.
