BOXED WARNING WARNING: LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL EXPOSURE; CYTOCHROME P450 3A4 INTERACTION; CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS; RISK OF MEDICATION ERRORS; ADDICTION, ABUSE, AND MISUSE; REMS; and NEONATAL OPIOID WITHDRAWAL SYNDROME Life-Threatening Respiratory Depression Serious, life-threatening, and/or fatal respiratory depression has occurred in patients treated with LAZANDA, including following use in opioid non-tolerant patients and improper dosing. Monitor for respiratory depression, especially during initiation of LAZANDA or following a dose increase. The substitution of LAZANDA for any other fentanyl product may result in fatal overdose [see Warnings and Precautions ( 5.1 )]. Due to the risk of respiratory depression, LAZANDA is contraindicated in the management of acute or postoperative pain including headache/migraine and in opioid non-tolerant patients. [see Contraindications ( 4 )] Accidental Exposure Accidental exposure of even one dose of LAZANDA, especially in children, can result in a fatal overdose of fentanyl [see Warnings and Precautions ( 5.1 )]. Death has been reported in children who have accidentally ingested transmucosal immediate-release fentanyl products. LAZANDA must be kept out of reach of children [see Warnings and Precautions ( 5.2 )]. Cytochrome P450 3A4 Interaction The concomitant use of LAZANDA with all cytochrome P450 3A4 inhibitors may result in an increase in fentanyl 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 fentanyl plasma concentration. Monitor patients receiving LAZANDA and any CYP3A4 inhibitor or inducer [see Warnings and Precautions ( 5.3 ), Drug Interactions ( 7 ), Clinical Pharmacology ( 12.2 )]. 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 ( 5.4 ), Drug Interactions ( 7 )]. Reserve concomitant prescribing of LAZANDA 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. Risk of Medication Errors Substantial differences exist in the pharmacokinetic profile of LAZANDA compared to other fentanyl products that result in clinically important differences in the extent of absorption of fentanyl that could result in fatal overdose [see Dosage and Administration ( 2.1 ), Warnings and Precautions ( 5.5 )]. When prescribing, do not convert patients on a mcg per mcg basis from any other fentanyl products to LAZANDA. When dispensing, do not substitute a LAZANDA prescription for other fentanyl products. Addiction, Abuse, and Misuse LAZANDA 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 LAZANDA, and monitor all patients regularly for the development of these behaviors and conditions [see Warnings and Precautions ( 5.6 )]. Risk Evaluation and Mitigation Strategy (REMS) Access Program Because of the risk for accidental exposure, misuse, abuse, addiction, and overdose, LAZANDA is available only through a restricted program required by the Food and Drug Administration, called a Risk Evaluation and Mitigation Strategy (REMS). Under the Transmucosal Immediate Release Fentanyl (TIRF) REMS, pharmacies, outpatients, and healthcare professionals who prescribe to outpatients must enroll in the program. Inpatient pharmacies must develop policies and procedures to verify opioid tolerance in inpatients who require LAZANDA while hospitalized [see Warnings and Precautions ( 5.7 )] Further information is available at www.TIRFREMSaccess.com or by calling 1-866-822-1483. Neonatal Opioid Withdrawal Syndrome Prolonged use of LAZANDA 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 ( 5.8 )]

5.12 Severe Hypotension LAZANDA may cause severe hypotension including orthostatic hypotension and syncope in ambulatory patients. There is increased risk in patients whose ability to maintain blood pressure has already been compromised by a reduced blood volume or concurrent administration of certain CNS depressant drugs (e.g. phenothiazines or general anesthetics) [see Drug Interactions ( 7 )]. Monitor these patients for signs of hypotension after initiating or titrating the dosage of LAZANDA. In patients with circulatory shock, LAZANDA may cause vasodilation that can further reduce cardiac output and blood pressure. Avoid the use of LAZANDA in patients with circulatory shock.

5.13 Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness In patients who may be susceptible to the intracranial effects of CO 2 retention (e.g., those with evidence of increased intracranial pressure or brain tumors), LAZANDA may reduce respiratory drive, and the resultant CO 2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with LAZANDA. Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of LAZANDA in patients with impaired consciousness or coma.

5.14 Risks of Use in Patients with Gastrointestinal Conditions LAZANDA is contraindicated in patients with known or suspected gastrointestinal obstruction, including paralytic ileus. The fentanyl in LAZANDA may cause spasm of the sphincter of Oddi. Opioids may cause increases in serum amylase. Monitor patients with biliary tract disease, including acute pancreatitis for worsening symptoms.

5.15 Increased Risk of Seizures in Patients with Seizure Disorders The fentanyl in LAZANDA may increase the frequency of seizures in patients with seizure disorders, and may increase the risk of seizures occurring in other clinical settings associated with seizures. Monitor patients with a history of seizure disorders for worsened seizure control during LAZANDA therapy.

ADVERSE REACTIONS 6.1 Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse event rates observed in the clinical trials of a drug product cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of LAZANDA has been evaluated in a total of 523 opioid-tolerant patients with breakthrough cancer pain. The average duration of therapy in patients in the long-term study was 73 days, with 153 patients being treated for over 3 months. Patients continuing into the open-label extension period of the safety study have been treated for up to 26 months. The clinical trials of LAZANDA were designed to evaluate safety and efficacy in treating breakthrough cancer pain; all patients were also taking concomitant opioids, such as sustained-release morphine, sustained-release oxycodone, or transdermal fentanyl, for their persistent cancer pain. The adverse reaction data presented in Table 1 reflect the actual percentage of patients experiencing each adverse effect among patients who received LAZANDA for breakthrough cancer pain along with a concomitant opioid for persistent cancer pain. There has been no attempt to correct for concomitant use of other opioids, duration of LAZANDA therapy, or cancer-related symptoms. Adverse events are included regardless of causality or severity. Table 1 lists adverse reactions with an overall frequency of 5% or greater within the total population that occurred during titration by maximum dose received. The ability to assign LAZANDA a dose-response relationship to these adverse events is limited by the titration schemes used in these studies.

Eye disorders: dry eye, swelling, ptosis, strabismus Blood and Lymphatic System Disorders: anemia, neutropenia Cardiac Disorders: cardiorespiratory arrest Gastrointestinal Disorders: vomiting, nausea, constipation, diarrhea, abdominal pain, gastritis, ascites, dry mouth, dyspepsia, mouth ulcer, proctalgia General Disorders and Administration Site Conditions: pyrexia, fatigue, edema peripheral, asthenia, edema Hepatobiliary Disorders: jaundice Immune System Disorders: hypersensitivity Infections and Infestations: urinary tract infection, pneumonia, nasopharyngitis, infection, rhinitis, upper respiratory tract infection, bronchitis Injury, Poisoning and Procedural Complications: fall Investigations: weight decreased, blood alkaline phosphatase increased Metabolism and Nutrition Disorders: dehydration, decreased appetite, hyperglycemia, anorexia Musculoskeletal and Connective Tissue Disorders: back pain, pain in extremity, arthralgia Nervous System Disorders: dizziness, somnolence, headache, dysgeusia Psychiatric Disorders: anxiety, insomnia, depression, confusional state, disorientation, agitation Respiratory, Thoracic and Mediastinal Disorders: dyspnea, epistaxis, cough, pharyngolaryngeal pain, nasal discomfort, rhinorrhea, nasal congestion, postnasal drip, pulmonary embolism Skin and Subcutaneous Tissue Disorders: pruritus, hyperhidrosis, decubitus ulcer, mouth ulceration Vascular Disorders: hypertension, deep vein thrombosis 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use fentanyl. 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. 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 LAZANDA. Androgen deficiency : Cases of androgen deficiency have occurred with chronic use of opioids [see Clinical Pharmacology ( 12.2 )].
