1 INDICATIONS AND USAGE Oxycodone Hydrochloride Oral Solution is indicated for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. Oxycodone Hydrochloride Oral Solution 100 mg per 5 mL (20 mg/mL) is indicated for the relief of pain in opioid-tolerant patients. Limitations of Use Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, [see Warnings and Precautions (5.2) ], reserve Oxycodone Hydrochloride Oral Solution for use in patients for whom alternative treatment options [e.g., non-opioid analgesics or opioid combination products] • Have not been tolerated or are not expected to be tolerated, • Have not provided adequate analgesia or are not expected to provide adequate analgesia Oxycodone Hydrochloride Oral Solution is an opioid agonist indicated for the management of pain severe enough to require an opioid analgesic and for which alternative treatments are inadequate. (1) Limitations of Use (1) Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, reserve Oxycodone Hydrochloride Oral Solution for use in patients for whom alternative treatment options [e.g., non-opioid analgesics or opioid combination products]: • Have not been tolerated or are not expected to be tolerated, • Have not provided adequate analgesia or are not expected to provide adequate analgesia

2 DOSAGE AND ADMINISTRATION Oxycodone Hydrochloride Oral Solution 100 mg per 5 mL (20 mg/mL) is for opioid-tolerant patients only ( 2.1 ) Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals. (2.1 ) Individualize dosing based on the severity of pain, patient response, prior analgesic experience, and risk factor for addiction, abuse, and misuse. ( 2.1 ) Initiate dosing with a range of 5 to 15 mg every 4 to 6 hours as needed for pain. ( 2.2 ) For control of chronic pain, administer Oxycodone Hydrochloride Oral Solution on a regularly scheduled basis, at the lowest dosage level to achieve adequate analgesia. ( 2.2 ) Individually titrate Oxycodone Hydrochloride Oral Solution to a dose that provides adequate analgesia and minimizes adverse reactions. ( 2.3 ) Do not abruptly discontinue Oxycodone Hydrochloride Oral Solution in a physically dependent patient because rapid discontinuation of Opioid analgesics has resulted in serious withdrawal symptoms, uncontrolled pain, and suicide. ( 2.4 ) 2.1 Important Dosage and Administration Instructions Oxycodone Hydrochloride Oral Solution is available in two concentrations: 5 mg per 5 mL (1 mg/mL), and 100 mg per 5 mL (20 mg/mL). Oxycodone Hydrochloride Oral Solution 100 mg per 5 mL (20 mg/mL) is for use in opioid-tolerant patients only who have already been receiving opioid therapy. Use this strength only for patients who have already been titrated to a stable analgesic regimen using lower strengths of oxycodone hydrochloride and who can benefit from use of a smaller volume of oral solution. Patients considered to be opioid tolerant are those who are receiving, for one week or longer, at least 60mg oral morphine per day, 25 mcg transdermal fentanyl per hour, 30 mg oral oxycodone per day, 8 mg oral hydromorphone per day, 25 mg oral oxymorphone per day, 60 mg oral hydrocodone per day, or an equianalgesic dose of another opioid. Ensure accuracy when prescribing, dispensing, and administering Oxycodone Hydrochloride Oral Solution to avoid dosing errors due to confusion between mg and mL, and with other oxycodone hydrochloride solutions of different concentrations, which could result in accidental overdose and death. Ensure the proper dose is communicated and dispensed. When writing prescriptions, include both the total dose in mg and the total dose in volume. Always use the enclosed calibrated measuring cup when administering Oxycodone Hydrochloride Oral Solution 5 mg per 5 mL and always use the enclosed calibrated oral syringe when administering Oxycodone Hydrochloride Oral Solution 100 mg per 5 mL (20 mg per mL) to ensure that the dose is measured and administered accurately. Do not use household teaspoons or tablespoons to measure Oxycodone Hydrochloride Oral Solution, as using a tablespoon instead of a teaspoon could lead to overdosage. Use the lowest effective dosage for the shortest duration consistent with individual patient treatment goals [see Warnings and Precautions (5) ]. Initiate the dosing regimen for each patient individually, taking into account the patient’s severity of pain, patient response, prior analgesic treatment experience, and risk factors for addiction, abuse, and misuse [see Warnings and Precautions (5.2) ]. Monitor patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy and following dosage increases with Oxycodone Hydrochloride Oral Solution and adjust the dosage accordingly [see Warnings and Precautions (5.4) ]. 2.2 Initial Dosage Although it is not possible to list every condition that is important to the selection of the initial dose of Oxycodone Hydrochloride Oral Solution, attention must be given to: 1. the daily dose, potency and characteristics of a full agonist or mixed agonist /antagonist the patient has been taking previously 2. the reliability of the relative potency estimate to calculate the dose of oxycodone HCl needed 3. the degree of opioid toler …

6 ADVERSE REACTIONS The following serious adverse reactions are described, or described in greater detail, in other sections: • Addiction, Abuse, and Misuse [see Warnings and Precautions (5.2)] • Life-Threatening Respiratory Depression [see Warnings and Precautions (5.4)] • Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.5)] • Interactions with Benzodiazepines or Other CNS Depressants [see Warnings and Precautions (5.7)] • Adrenal Insufficiency [see Warnings and Precautions (5.9)] • Severe Hypotension [see Warnings and Precautions (5.10)] • Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.12)] • Seizures [see Warnings and Precautions (5.13)] • Withdrawal [see Warnings and Precautions (5.14)] The following adverse reactions associated with the use of oxycodone were identified in clinical studies or post marketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Serious adverse reactions associated with oxycodone use included: respiratory depression, respiratory arrest, circulatory depression, cardiac arrest, hypotension, and/or shock. The common adverse reactions seen on initiation of therapy with oxycodone are dose-related and are typical opioid-related adverse reactions. The most frequent adverse events include nausea, constipation, vomiting, headache, and pruritus. The frequency of these reactions depended on several factors, including clinical setting, the patient’s level of opioid tolerance, and host factors specific to the individual. In all patients for whom dosing information was available (n=191) from the open-label and double-blind studies involving another formulation of immediate-release oxycodone, the following adverse events were recorded in oxycodone treated patients with an incidence ≥ 3%. In descending order of frequency, they were: nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence. The other less frequently observed adverse reactions from opioid analgesics, including Oxycodone Hydrochloride Oral Solution included: Body as a Whole: abdominal pain, accidental injury, allergic reaction, back pain, chills and fever, fever, flu syndrome, infection, neck pain, pain, photosensitivity reaction, and sepsis. Cardiovascular: deep thrombophlebitis, heart failure, hemorrhage, hypotension, migraine, palpitation, and tachycardia. Digestive : anorexia, diarrhea, dyspepsia, dysphagia, gingivitis, glossitis, and nausea and vomiting. Hemic and Lymphatic: anemia and leukopenia. Metabolic and Nutritional: edema, gout, hyperglycemia, iron deficiency anemia and peripheral edema. Musculoskeletal: arthralgia, arthritis, bone pain, myalgia and pathological fracture. Nervous: agitation, anxiety, confusion, dry mouth, hypertonia, hypesthesia, nervousness, neuralgia, personality disorder, tremor, and vasodilation. Respiratory: bronchitis, cough increased, dyspnea, epistaxis, laryngismus, lung disorder, pharyngitis, rhinitis, and sinusitis. Skin and Appendages: herpes simplex, rash, sweating, and urticaria. Special Senses: amblyopia. Urogenital: urinary tract infection Serotonin syndrome: Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs. Adrenal insufficiency: Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. Anaphylaxis: Anaphylaxis has been reported with ingredients contained in Oxycodone Hydrochloride Oral Solution. Androgen deficiency: Cases of androgen deficiency have occurred with chronic use of opioids [see Clinical Pharmacology (12.2) ]. Most common adverse reactions are nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence. (6) To report SUSPECTED ADVERSE REACTIONS, co …

7 DRUG INTERACTIONS Table 1 includes clinically significant drug interactions with Oxycodone Hydrochloride Oral Solution. Table 1: Clinically Significant Drug Interactions with Oxycodone Hydrochloride Oral Solution Inhibitors of CYP3A4 and CYP2D6 Clinical Impact: The concomitant use of Oxycodone Hydrochloride Oral Solution and CYP3A4 inhibitors can increase the plasma concentration of oxycodone, resulting in increased or prolonged opioid effects. These effects could be more pronounced with concomitant use of Oxycodone Hydrochloride Oral Solution and CYP2D6 and CYP3A4 inhibitors, particularly when an inhibitor is added after a stable dose of Oxycodone Hydrochloride Oral Solution is achieved [see Warnings and Precautions (5.6) ]. After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the oxycodone plasma concentration will decrease [see Clinical Pharmacology (12.3) ] , resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to oxycodone. Intervention: If concomitant use is necessary, consider dosage reduction of Oxycodone Hydrochloride Oral Solution until stable drug effects are achieved. Monitor patients for respiratory depression and sedation at frequent intervals. If a CYP3A4 inhibitor is discontinued, consider increasing the Oxycodone Hydrochloride Oral Solution dosage until stable drug effects are achieved. Monitor for signs of opioid withdrawal. Example Macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g. ketoconazole), protease inhibitors (e.g., ritonavir) CYP3A4 Inducers Clinical Impact: The concomitant use of Oxycodone Hydrochloride Oral Solution and CYP3A4 inducers can decrease the plasma concentration of oxycodone [see Clinical Pharmacology (12.3) ], resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to oxycodone [see Warnings and Precautions (5.6) ]. After stopping a CYP3A4 inducer, as the effects of the inducer decline, the oxycodone plasma concentration will increase [see Clinical Pharmacology (12.3) ], which could increase or prolong both the therapeutic effects and adverse reactions, and may cause serious respiratory depression. Intervention: If concomitant use is necessary, consider increasing the Oxycodone Hydrochloride Oral Solution dosage until stable drug effects are achieved. Monitor for signs of opioid withdrawal. If a CYP3A4 inducer is discontinued, consider Oxycodone Hydrochloride Oral Solution dosage reduction and monitor for signs of respiratory depression. Examples Rifampin, carbamazepine, phenytoin Benzodiazepines and other Central Nervous System (CNS) Depressants Clinical Impact: Due to additive pharmacologic effect, the concomitant use of benzodiazepines or other CNS depressants including alcohol, increases the risk of respiratory depression, profound sedation, coma, and death. Intervention: Reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate. Limit dosages and durations to the minimum required. Follow patients closely for signs of respiratory depression and sedation [see Warnings and Precautions (5.7) ] . Examples Benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol. Serotonergic Drugs Clinical Impact: The concomitant use of opioids with other drugs that affect the serotonergic neurotransmitter system has resulted in serotonin syndrome. Intervention: If concomitant use is warranted, carefully observe the patient, particularly during treatment initiation and dose adjustment. Discontinue Oxycodone Hydrochloride Oral Solution if serotonin syndrome is suspected. Examples: Selective serotonin reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the ser …

8 USE IN SPECIFIC POPULATIONS • Pregnancy: May cause fetal harm. (8.1) 8.1 Pregnancy Risk Summary Prolonged use of opioid analgesics during pregnancy may cause neonatal opioid withdrawal syndrome [see Warnings and Precautions (5.5) ]. Available data with Oxycodone Hydrochloride Oral Solution are insufficient to inform a drug-associated risk for major birth defects and miscarriage. Animal reproduction studies with oral administrations of oxycodone hydrochloride in rats and rabbits during the period of organogenesis at doses 2.6 and 8.1 times, respectively, the human dose of 60 mg/day did not reveal evidence of teratogenicity or embryo-fetal toxicity. In several published studies, treatment of pregnant rats with oxycodone at clinically relevant doses and below, resulted in neurobehavioral effects in offspring [see Data]. Based on animal data, advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions Prolonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth. Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high pitched cry, tremor, vomiting, diarrhea, and failure to gain weight. The onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn. Observe newborns for symptoms of neonatal opioid withdrawal syndrome and manage accordingly [see Warnings and Precautions (5.5)]. Labor or Delivery Opioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in neonates. An opioid antagonist, such as naloxone, must be available for reversal of opioid-induced respiratory depression in the neonate. Oxycodone Hydrochloride Oral Solution is not recommended for use in pregnant women during or immediately prior to labor, when other analgesic techniques are more appropriate. Opioid analgesics, including Oxycodone Hydrochloride Oral Solution, can prolong labor through actions which temporarily reduce the strength, duration, and frequency of uterine contractions. However, this effect is not consistent and may be offset by an increased rate of cervical dilation, which tends to shorten labor. Monitor neonates exposed to opioid analgesics during labor for signs of excess sedation and respiratory depression. Data Animal Data In embryo-fetal development studies in rats and rabbits, pregnant animals received oral doses of oxycodone hydrochloride administered during the period of organogenesis up to 16 mg/kg/day and up 25 mg/kg/day, respectively. These studies revealed no evidence of teratogenicity or embryo-fetal toxicity due to oxycodone. The highest doses tested in rats and rabbits were equivalent to approximately 2.6 and 8.1 times an adult human dose of 60 mg/day, respectively, on a mg/m 2 basis. In published studies, offspring of pregnant rats administered oxycodone during gestation have been reported to exhibit neurobehavioral effects including altered stress responses, increased anxiety-like behavior (2 mg/kg/day IV from Gestation Day 8 to 21 and Postnatal Day 1, 3, and 5; 0.3-times an adult human dose of 60 mg/day, on a mg/m 2 basis) and altered learning and memory (15 mg/kg/day orally from breeding through parturition; 2.4 times an adult human dose of 60 mg/day, on a mg/m 2 basis). 8.2 Lactation Risk Summary Oxycodone is present in breast milk. Published lactat …

12.1 Mechanism of Action Oxycodone is a full opioid agonist and is relatively selective for the mu-opioid receptor, although it can bind to other opioid receptors at higher doses. The principal therapeutic action of oxycodone is analgesia. Like all full opioid agonists, there is no ceiling effect for analgesia with oxycodone. Clinically, dosage is titrated to provide adequate analgesia and may be limited by adverse reactions, including respiratory and CNS depression. The precise mechanism of the analgesic action is unknown. However, specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and are thought to play a role in the analgesic effects of this drug.

11 DESCRIPTION Oxycodone Hydrochloride Oral Solution is an agonist, available as a red solution 5 mg/5 mL (1 mg/mL) and a yellow solution 100 mg/5 mL (20 mg/mL) for oral administration.

10 OVERDOSAGE Clinical Presentation Acute overdose with Oxycodone Hydrochloride Oral Solution can be manifested by respiratory depression, somnolence progressing to stupor or coma, skeletal muscle flaccidity, cold and clammy skin, constricted pupils, and, in some cases, pulmonary edema, bradycardia, hypotension, partial or complete airway obstruction, atypical snoring, and death. Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations [see Clinical Pharmacology (12.2) ]. Treatment of Overdose In case of overdose, priorities are the reestablishment of a patent and protected airway and institution of assisted or controlled ventilation, if needed. Employ other supportive measures (including oxygen and vasopressors) in the management of circulatory shock and pulmonary edema as indicated. Cardiac arrest or arrhythmias will require advanced life-support techniques. The opioid antagonists, naloxone or nalmefene, are specific antidotes to respiratory depression resulting from opioid overdose. For clinically significant respiratory or circulatory depression secondary to oxycodone overdose, administer an opioid antagonist. Opioid antagonists should not be administered in the absence of clinically significant respiratory or circulatory depression secondary to oxycodone overdose. Because the duration of opioid reversal is expected to be less than the duration of action of oxycodone in Oxycodone Hydrochloride Oral Solution, carefully monitor the patient until spontaneous respiration is reliably re-established. If the response to an opioid antagonist is suboptimal or only brief in nature, administer additional antagonist as directed by the product’s prescribing information. In an individual physically dependent on opioids, administration of the recommended usual dosage of the antagonist will precipitate an acute withdrawal syndrome. The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered. If a decision is made to treat serious respiratory depression in the physically dependent patient, administration of the antagonist should be initiated with care and by titration with smaller than usual doses of the antagonist.
