WARNING: ADDICTION, ABUSE, AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; NEONATAL OPIOID WITHDRAWAL SYNDROME; CYTOCHROME P450 3A4 INTERACTION; and RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS Addiction, Abuse, and Misuse Oxycodone hydrochloride tablets expose 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 hydrochloride tablets, and monitor all patients regularly for the development of these behaviors and conditions [see Warnings and Precautions (5.1) ] . Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression may occur with use of oxycodone hydrochloride tablets. Monitor for respiratory depression, especially during initiation of oxycodone hydrochloride tablets or following a dose increase [see Warnings and Precautions (5.2) ] . Accidental Ingestion Accidental ingestion of even one dose of oxycodone hydrochloride tablets, especially by children, can result in a fatal overdose of oxycodone [see Warnings and Precautions (5.2) ] . Neonatal Opioid Withdrawal Syndrome Prolonged use of oxycodone hydrochloride tablets 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 that appropriate treatment will be available [see Warnings and Precautions (5.3) ] . Cytochrome P450 3A4 Interaction The concomitant use of oxycodone hydrochloride tablets 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 hydrochloride tablets and any CYP3A4 inhibitor or inducer [see Warnings and Precautions (5.4) , Drug Interactions (7) , Clinical Pharmacology (12.3) ] . Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death [see Warnings and Precautions (5.5) , Drug Interactions (7) ] . Reserve concomitant prescribing of oxycodone hydrochloride tablets 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. WARNING: ADDICTION, ABUSE, AND MISUSE; LIFE- THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; NEONATAL OPIOID WITHDRAWAL SYNDROME; CYTOCHROME P450 3A4 INTERACTION; and RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS See full prescribing information for complete boxed warning. Oxycodone hydrochloride tablets expose users to risks of addiction, abuse, and misuse, which can lead to overdose and death. Assess patient’s risk before prescribing and monitor regularly for these behaviors and conditions. ( 5.1 ) Serious, life-threatening, or fatal respiratory depression may occur. Monitor closely, especially upon initiation or following a dose increase. ( 5.2 ) Accidental ingestion of oxycodone hydrochloride tablets, especially by children, can result in a fatal overdose of oxycodone. ( 5.2 ) Prolonged use of oxycodone hydrochloride tablets during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated. If prolonged opioid use is required in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available. ( 5.3 ) Concomitant use with CYP3A4 inhibitors (or discontinuation of CYP3A4 inducers) can result in a fatal overdose of oxycodone from oxycodone hydrochloride tablets. ( 5.4 , 7 , 12.3 ) Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death. Reserve concomitant prescribing for use in patients for whom alternative treatment options are inadequate; limit dosages and durations to the minimum required; and follow patients for signs and symptoms of respiratory depression and sedation. ( 5.5 , 7 )

5.12 Withdrawal Avoid the use of mixed agonist/antagonist (e.g., pentazocine, nalbuphine, and butorphanol) or partial agonist (e.g., buprenorphine) analgesics in patients who are receiving a full opioid agonist analgesic, including oxycodone hydrochloride tablets. In these patients, mixed agonist/antagonist and partial agonist analgesics may reduce the analgesic effect and/or precipitate withdrawal symptoms [see Drug Interactions (7) ] . When discontinuing oxycodone hydrochloride tablets in a physically-dependent patient, gradually taper the dosage [see Dosage and Administration (2.4) ]. Do not abruptly discontinue oxycodone hydrochloride tablets in these patients [see Drug Abuse and Dependence (9.3) ] .

5.13 Risks of Driving and Operating Machinery Oxycodone hydrochloride tablets may impair the mental or physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of oxycodone hydrochloride tablets and know how they will react to the medication [see Patient Counseling Information (17) ] .

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 (5.1) ] Life-Threatening Respiratory Depression [see Warnings and Precautions (5.2) ] Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions (5.3) ] Interactions with Benzodiazepines or Other CNS Depressants [see Warnings and Precautions (5.5) ] Adrenal Insufficiency [see Warnings and Precautions (5.7) ] Severe Hypotension [see Warnings and Precautions (5.8) ] Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.10) ] Seizures [see Warnings and Precautions (5.11) ] Withdrawal [see Warnings and Precautions (5.12) ] Most common adverse reactions (≥3%) were nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Par Pharmaceutical at 1-800-828-9393 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Oxycodone hydrochloride tablets have been evaluated in open label clinical trials in patients with cancer and nonmalignant pain. Oxycodone hydrochloride tablets are associated with adverse experiences similar to those seen with other opioids. Serious adverse reactions associated with oxycodone hydrochloride tablets 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 hydrochloride tablets are dose related and are typical opioid-related adverse reactions. The most frequent of these included nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence. 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 oxycodone hydrochloride tablets, the following adverse events were recorded in oxycodone hydrochloride tablets treated patients with an incidence ≥ 3%. In descending order of frequency they were: nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence. Other less frequently observed adverse reactions from opioid analgesics, including oxycodone hydrochloride tablets included: Blood and lymphatic system disorders : anemia, leukopenia Cardiac disorders : cardiac failure, palpitation, tachycardia Gastrointestinal disorders : abdominal pain, dry mouth, diarrhea, dyspepsia, dysphagia, glossitis, nausea, vomiting. General disorders and administration site conditions : chills, edema, edema peripheral, pain, pyrexia Immune system disorders : hypersensitivity Infections and infestations : bronchitis, gingivitis, infection, pharyngitis, rhinitis, sepsis, sinusitis, urinary tract infection Injury, poisoning and procedural complications : injury Metabolism and nutrition disorders : decreased appetite, gout, hyperglycemia Musculoskeletal and connective tissue disorders : arthralgia, arthritis, back pain, bone pain, myalgia, neck pain, pathological fracture Nervous system disorders : hypertonia, hypoesthesia, migraine, neuralgia, tremor, vasodilation Psychiatric disorders : agitation, anxiety, confusional state, nervousness, personality disorder Respiratory, thoracic and mediastinal disorders : cough, dyspnea, epistaxis, laryngospasm, lung disorder Skin and subcutaneous tissue disorders : photosensitivity reaction, rash, hyperhidrosis, urticaria Vascular disorders : thrombophlebitis, hemorrhage, hypotension, vasodilatation 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of oxycodone. Because these reactions are 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. General disorders and administrative site disorders : drug withdrawal syndrome neonatal [see Warnings and Precautions (5.3) ] Respiratory, thoracic and mediastinal disorders : pharyngeal edema Serotonin syndrome : Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during concomitant use of opioids with serotonergic drugs [see Drug Interactions (7) ]. Adrenal insufficiency : Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use [see Warnings and Precautions (5.7) ]. Anaphylaxis : Anaphylactic reaction has been reported with ingredients contained in oxycodone hydrochloride tablets [see Contraindications (4) ]. Androgen deficiency : Cases of androgen deficiency have occurred with chronic use of opioids [see Clinical Pharmacology (12.2) ] .
