Oxycodone Hydrochloride 15 mg Tablet, 100-count — NDC 0904-7180-61 (Billing 00904-7180-61)

5 WARNINGS AND PRECAUTIONS • Opioid-Induced Hyperalgesia and Allodynia: Opioid-Induced Hyperalgesia (OIH) occurs when opioid analgesic paradoxically causes an increase in pain, or an increase in sensitivity to pain. If OIH is suspected, carefully consider appropriately decreasing the dose of the current opioid analgesic, or opioid rotation. (5.7) • Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients: Regularly evaluate closely, particularly during initiation and titration.

(5.8) • Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. (5.9) • Severe Hypotension: Regularly evaluate during dosage initiation and titration. Avoid use of oxycodone HCl in patients with circulatory shock.

(5.10) • Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness: Monitor for sedation and respiratory depression. Avoid use of oxycodone HCl tablets in patients with impaired consciousness or coma. (5.11)

5.1Addiction, Abuse, and Misuse Oxycodone HCl tablets contains oxycodone, a Schedule II controlled substance. As an opioid, oxycodone HCl exposes users to the risks of addiction, abuse, and misuse [see Drug Abuse and Dependence (9) ] . Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed oxycodone HCl.

Addiction can occur at recommended dosages and if the drug is misused or abused. The risk of opioid-related overdose or overdose-related death is increased with higher opioid doses, and this risk persists over the course of therapy. In postmarketing studies, addiction, abuse, misuse, and fatal and non-fatal opioid overdose were observed in patients with long-term opioid use [see Adverse Reactions (6.2) ] .

Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing oxycodone HCl, and reassess all patients receiving oxycodone HCl for the development of these behaviors and conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient.

Patients at increased risk may be prescribed opioids such as oxycodone HCl, but use in such patients necessitates intensive counseling about the risks and proper use of oxycodone HCl along with frequent reevaluation for signs of addiction, abuse, and misuse. Consider recommending or prescribing an opioid overdose reversal agent [see Dosage and Administration (2.2) , Warnings and Precautions (5.2) ] . Opioids are sought for nonmedical use and are subject to diversion from legitimate prescribed use.

Consider these risks when prescribing or dispensing oxycodone HCl. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on careful storage of the drug during the course of treatment and on the proper disposal of unused drugs. Contact local state professional licensing board or state-controlled substances authority for information on how to prevent and detect abuse or diversion of this product.

5.2Life-Threatening Respiratory Depression Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended. Respiratory depression, if not immediately recognized and treated, may lead to respiratory arrest and death. Management of respiratory depression may include close observation, supportive measures, and use of opioid overdose reversal agents (e.g., naloxone, nalmefene), depending on the patient’s clinical status [see Overdosage (10) ] .

Carbon dioxide (CO 2 ) retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. While seriou… [Excerpted — this section continues on DailyMed.]

6.1Clinical 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 HCl tablets have been evaluated in open label clinical trials in patients with cancer and nonmalignant pain. Oxycodone HCl tablets are associated with adverse experiences similar to those seen with other opioids.

Serious adverse reactions associated with oxycodone HCl 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 HCl 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 HCl, the following adverse events were recorded in oxycodone HCl 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 HCl 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, vasodila… [Excerpted — this section continues on DailyMed.]

7 DRUG INTERACTIONS Table 1 includes clinically significant drug interactions with oxycodone HCl. Table 1: Clinically Significant Drug Interactions with Oxycodone HCl Inhibitors of CYP3A4 and CYP2D6 Clinical Impact: The concomitant use of oxycodone HCl 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 HCl and CYP2D6 and CYP3A4 inhibitors, particularly when an inhibitor is added after a stable dose of oxycodone HCl is achieved [see Warnings and Precautions (5.3) ] .

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 HCl until stable drug effects are achieved. Evaluate patients at frequent intervals for respiratory depression and sedation.

If a CYP3A4 inhibitor is discontinued, consider increasing the oxycodone HCl dosage until stable drug effects are achieved. Evaluate for signs of opioid withdrawal. Examples: 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 HCl 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 HCl dosage until stable drug effects are achieved. Evaluate patients for signs of opioid withdrawal. If a CYP3A4 inducer is discontinued, consider oxycodone HCl dosage reduction and evaluate patients at frequent intervals for signs of respiratory depression and sedation.

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, can increase the risk of hypotension, respiratory depression, profound sedation, coma, and death [see Warnings and Precautions (5.3) ] . 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. Inform patients and caregivers of this potential interaction and educate them on the signs and symptoms of respiratory depression (including sedation). If concomitant use is warranted, consider recommending or prescribing an opioid overdose reversal agent [see Dosage and Administration (2.2) , Warnings and Precautions (5.1 , 5.2 , 5.3) ] .

Examples: Benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, gabapentinoids (gabapentin or pregabalin), 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 [see Adverse Reactions (6.2) ] . Intervention: If concomitant use is warranted, frequently evaluate the patient, particularly during treatment initiation and dose adjustment.

Discontinue oxycodone HCl if serotonin syndrome is suspected. Examples: Selective serotonin reuptake inhibitors… [Excerpted — this section continues on DailyMed.]

9 DRUG ABUSE AND DEPENDENCE

9.1Controlled Substance Oxycodone HCl tablets contains oxycodone, a Schedule II controlled substance.

9.2Abuse Oxycodone HCl tablets contains oxycodone, a substance with high potential for misuse and abuse, which can lead to the development of substance use disorder, including addiction [see Warnings and Precautions (5.1) ] . Misuse is the intentional use, for therapeutic purposes, of a drug by an individual in a way other than prescribed by a healthcare provider or for whom it was not prescribed. Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects.

Drug addiction is a cluster of behavioral, cognitive, and physiological phenomena that may include a strong desire to take the drug, difficulties in controlling drug use (e.g., continuing drug use despite harmful consequences, giving a higher priority to drug use than other activities and obligations), and possible tolerance or physical dependence. Misuse and abuse of oxycodone HCl increases risk of overdose, which may lead to central nervous system and respiratory depression, hypotension, seizures, and death. The risk is increased with concurrent abuse of oxycodone HCl with alcohol and/or other CNS depressants.

Abuse of and addiction to opioids in some individuals may not be accompanied by concurrent tolerance and symptoms of physical dependence. In addition, abuse of opioids can occur in the absence of addiction. All patients treated with opioids require careful and frequent reevaluation for signs of misuse, abuse, and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use.

Patients at high risk of oxycodone HCl abuse include those with a history of prolonged use of any opioid, including products containing oxycodone, those with a history of drug or alcohol abuse, or those who use oxycodone HCl in combination with other abused drugs. “Drug-seeking” behavior is very common in persons with substance use disorders. Drug-seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing, or referral, repeated “loss” of prescriptions, tampering with prescriptions, and reluctance to provide prior medical records or contact information for other treating healthcare provider(s). “Doctor shopping” (visiting multiple prescribers to obtain additional prescriptions) is common among people who abuse drugs and people with substance use disorder.

Preoccupation with achieving adequate pain relief can be appropriate behavior in a patient with inadequate pain control. Oxycodone HCl, like other opioids, can be diverted for nonmedical use into illicit channels of distribution. Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests, as required by state and federal law, is strongly advised.

Proper assessment of the patient, proper prescribing practices, periodic reevaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs. Risks Specific to Abuse of Oxycodone HCl Abuse of oxycodone HCl poses a risk of overdose and death. The risk is increased with concurrent use of oxycodone HCl with alcohol and/or other CNS depressants.

Oxycodone HCl is approved for oral use only. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.

9.3Dependence Both tolerance and physical dependence can develop during use of opioid therapy. Tolerance is a physiological state characterized by a reduced response to a drug after repeated administration (i.e., a higher dose of a drug is required to produce the same effect that was once obtained at a lower dose). Physical dependence is a state that develops as a result of a physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt di… [Excerpted — this section continues on DailyMed.]
