1 INDICATIONS AND USAGE Buprenorphine and naloxone sublingual film is indicated for treatment of opioid dependence. Buprenorphine and naloxone sublingual film should be used as part of a complete treatment plan that includes counseling and psychosocial support. Buprenorphine and naloxone sublingual film contains buprenorphine, a partial-opioid agonist, and naloxone, an opioid antagonist, and is indicated for treatment of opioid dependence. ( 1 ) Buprenorphine and naloxone sublingual film should be used as part of a complete treatment plan that includes counseling and psychosocial support. ( 1 )

2 DOSAGE AND ADMINISTRATION Administer buprenorphine and naloxone sublingual film as a single daily dose. ( 2.1 ) Strongly consider recommending or prescribing an opioid overdose reversal agent (e.g., naloxone, nalmefene) at the time buprenorphine and naloxone sublingual film is initiated or renewed because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose. ( 2.2 ) To avoid precipitating withdrawal, induction with buprenorphine and naloxone sublingual film should be undertaken when objective and clear signs of withdrawal are evident and buprenorphine and naloxone sublingual film should be administered in divided doses when used as initial treatment. ( 2.3 ) For patients dependent on short-acting opioid products who are in opioid withdrawal; on Day 1, administer up to 8 mg/2 mg buprenorphine and naloxone sublingual film (in divided doses). On Day 2, administer up to 16 mg/4 mg of buprenorphine and naloxone sublingual film as a single dose. ( 2.3 ) For patients dependent on methadone or long-acting opioid products, induction onto sublingual buprenorphine monotherapy is recommended on Days 1 and 2 of treatment. ( 2.3 ) The maintenance dose of buprenorphine and naloxone sublingual film is generally in the range of 4 mg/1 mg to 24 mg/6 mg per day and should be based on clinical response. ( 2.4 ) Sublingual Administration: Place one film under the tongue, close to the base on the left or right side, and allow to completely dissolve. Buccal Administration: Place one film on the inside of the left or right cheek and allow to completely dissolve. ( 2.5 ) Buprenorphine and naloxone sublingual film must be administered whole. Do not cut, chew, or swallow buprenorphine and naloxone sublingual film. ( 2.5 ) When discontinuing treatment, gradually taper to avoid signs and symptoms of withdrawal. ( 2.8 ) 2.1 Important Dosage and Administration Information Buprenorphine and naloxone sublingual film is administered sublingually or buccally as a single daily dose. Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised early in treatment or without appropriate patient follow-up visits. 2.2 Patient Access to an Opioid Overdose Reversal Agent for the Emergency Treatment of Opioid Overdose Inform patients and caregivers about opioid overdose reversal agents (e.g., naloxone, nalmefene) and discuss the importance of having access to an opioid overdose reversal agent. Because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose, strongly consider recommending or prescribing an overdose reversal agent for the emergency treatment of opioid overdose, both when initiating and renewing treatment with buprenorphine and naloxone sublingual film. Also consider recommending or prescribing such an agent if the patient has household members (including children) or other close contacts at risk for accidental ingestion or opioid overdose [see Warnings and Precautions ( 5.2 )] . Discuss the options for obtaining an opioid overdose reversal agent (e.g., prescription, over-the-counter, or as part of a community-based program) [see Warnings and Precautions ( 5.2 )] . There are important differences among the opioid overdose reversal agents, such as route of administration, product strength, approved patient age range, and pharmacokinetics. Be familiar with these differences, as outlined in the approved labeling for those products, prior to recommending or prescribing such an agent. Advise patients and caregivers that opioid overdose reversal agents, such as naloxone or nalmefene, may also be administered for a known or suspected overdose with buprenorphine itself. Higher than normal doses and repeated administration of an opioid overdose reversal agent may be necessary due to the long duration of action of buprenorphine and its affinity for the mu-opioid receptor [see Overdosage ( 10 )] . 2.3 Induction Prior to induction, consideration should be given to the type of opioid dependence (i.e., long- or short-acting opioid products), the time since last opioid use, and the degree or level of opioid dependence. Patients dependent on heroin or other short-acting opioid products Patients dependent on heroin or other short-acting opioid products may be inducted with either buprenorphine and naloxone sublingual film or with sublingual buprenorphine monotherapy. At treatment initiation, the first dose of buprenorphine and naloxone sublingual film should be administered when objective signs of moderate opioid withdrawal appear, not less than six hours after the patient last used opioids. It is recommended that an adequate treatment dose, titrated to clinical effectiveness, be achieved as rapidly as possible. In some studies, a too-gradual induction over several days led to a high rate of drop-out of buprenorphine patients during the induction period. On Day 1, an induction dosage of up to 8 mg/2 mg buprenorphine and naloxone sublingual film is recommended. Clinicians should start with an initial dose of 2 mg/0.5 mg or 4 mg/1 mg buprenorphine and naloxone and may titrate upwards in 2 mg or 4 mg increments of buprenorphine, at approximately 2-hour intervals, under supervision, to 8 mg/2 mg buprenorphine and naloxone based on the control of acute withdrawal symptoms. On Day 2, a single daily dose of up to 16 mg/4 mg buprenorphine and naloxone sublingual film is recommended. Because the exposure to naloxone is somewhat higher after buccal than after sublingual administration, it is recommended that the sublingual site of administration be used during induction to minimize exposure to naloxone, to reduce the risk of precipitated withdrawal. Patients dependent on methadone or long-acting opioid products Patients dependent upon methadone or long-acting opioid products may be more susceptible to precipitated and prolonged withdrawal during induction than those on short-acting opioid products. Buprenorphine and naloxone combination products have not been evaluated in adequate and well-controlled studies for induction in patients who are physically dependent on long-acting opioid products, and the naloxone in these combination products is absorbed in small amounts by the sublingual route and could cause worse precipitated and prolonged withdrawal. For this reason, buprenorphine monotherapy is recommended in patients taking long-acting opioids when used according to approved administration instructions. Following induction, the patient may then be transitioned to once-daily buprenorphine and naloxone sublingual film. 2.4 Maintenance For maintenance, buprenorphine and naloxone sublingual film may be administered buccally or sublingually. The dosage of buprenorphine and naloxone sublingual film from Day 3 onwards should be progressively adjusted in increments/decrements of 2 mg/0.5 mg or 4 mg/1 mg buprenorphine and naloxone to a level that holds the patient in treatment and suppresses opioid withdrawal signs and symptoms. After treatment induction to the recommended dose of 16 mg/4 mg buprenorphine and naloxone per day, dosing should be further adjusted based on the individual patient and clinical response. The maintenance dose of buprenorphine and naloxone sublingual film is generally in the range of 4 mg/1 mg buprenorphine and naloxone to 24 mg/6 mg buprenorphine and naloxone per day. Dosages higher than 24 mg/6 mg daily have not been investigated in randomized clinical trials but may be appropriate for some patients. When determining the prescription quantity for unsupervised administration, consider the patient’s level of stability, the security of his or her home situation, and other factors likely to affect the ability to manage supplies of take-home medication. There is no maximum recommended duration of maintenance treatment. Patients may require treatment indefinitely and should continue for as long as patients are benefiting and the use of buprenorphine and naloxone sublingual film contributes to the intended treatment goals. 2.5 Method of Administration Buprenorphine and naloxone sublingual film must be administered whole. Do not cut, chew, or swallow buprenorphine and naloxone sublingual film. Advise patients not to eat or drink anything until the film is completely dissolved. Sublingual Administration Place one film under the tongue, close to the base on the left or right side. If an additional film is necessary to achieve the prescribed dose, place an additional film sublingually on the opposite side from the first film. Place the film in a manner to minimize overlapping as much as possible. The film must be kept under the tongue until the film is completely dissolved. If a third film is necessary to achieve the prescribed dose, place it under the tongue on either side after the first 2 films have dissolved. Buccal Administration Place one film on the inside of the right or left cheek. If an additional film is necessary to achieve the prescribed dose, place an additional film on the inside of the opposite cheek. The film must be kept on the inside of the cheek until the film is completely dissolved. If a third film is necessary to achieve the prescribed dose, place it on the inside of the right or left cheek after the first two films have dissolved. Buprenorphine and naloxone sublingual film should NOT be moved after placement. To ensure consistency in bioavailability, patients should follow the same manner of dosing with continued use of the product. Proper administration technique should be demonstrated to the patient. Advise patients to do the following after the product has completely dissolved in the oral mucosa: take a sip of water, swish gently around the teeth and gums, and swallow. Advise patients to wait for at least one hour after taking buprenorphine and naloxone sublingual film before brushing teeth [see Warnings and Precautions ( 5.13 ), Postmarketing Experience ( 6.2 ), Information for Patients ( 17 ), and the Medication Guide]. 2.6 Clinical Supervision Treatment should be initiated with supervised administration, progressing to unsupervised administration as the patient’s clinical stability permits. Buprenorphine and naloxone sublingual film is subject to diversion and abuse. When determining the prescription quantity for unsupervised administration, consider the patient’s level of stability, the security of his or her home situation, and other factors likely to affect the ability to manage supplies of take-home medication. Ideally patients should be seen at reasonable intervals (e.g., at least weekly during the first month of treatment) based upon the individual circumstances of the patient. Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised early in treatment or without appropriate patient follow-up visits. Periodic assessment is necessary to determine compliance with the dosing regimen, effectiveness of the treatment plan, and overall patient progress. Once a stable dosage has been achieved and patient assessment (e.g., urine drug screening) does not indicate illicit drug use, less frequent follow-up visits may be appropriate. A once-monthly visit schedule may be reasonable for patients on a stable dosage of medication who are making progress toward their treatment objectives. Continuation or modification of pharmacotherapy should be based on the healthcare provider’s evaluation of treatment outcomes and objectives such as: Absence of medication toxicity. Absence of medical or behavioral adverse effects. Responsible handling of medications by the patient. Patient’s compliance with all elements of the treatment plan (including recovery-oriented activities, psychotherapy, and/or other psychosocial modalities). Abstinence from illicit drug use (including problematic alcohol and/or benzodiazepine use). If treatment goals are not being achieved, the healthcare provider should re-evaluate the appropriateness of continuing the current treatment. 2.7 Unstable Patients Healthcare providers will need to decide when they cannot appropriately provide further management for particular patients. For example, some patients may be abusing or dependent on various drugs, or unresponsive to psychosocial intervention such that the healthcare provider does not feel that he/she has the expertise to manage the patient. In such cases, the healthcare provider may want to assess whether to refer the patient to a specialist or more intensive behavioral treatment environment. Decisions should be based on a treatment plan established and agreed upon with the patient at the beginning of treatment. Patients who continue to misuse, abuse, or divert buprenorphine products or other opioids should be provided with, or referred to, more intensive and structured treatment. 2.8 Discontinuing Treatment The decision to discontinue therapy with buprenorphine and naloxone sublingual film after a period of maintenance should be made as part of a comprehensive treatment plan. Advise patients of the potential to relapse to illicit drug use following discontinuation of opioid agonist/partial agonist medication-assisted treatment. Taper patients to reduce the occurrence of opioid withdrawal signs and symptoms [see Warnings and Precautions ( 5.7 )] . 2.9 Switching Between Buprenorphine or Buprenorphine and Naloxone Sublingual Tablets and Buprenorphine and Naloxone Sublingual Film Patients being switched between buprenorphine and naloxone or buprenorphine only sublingual tablets and buprenorphine and naloxone sublingual film should be started on the same dosage of the previously administered product. However, dosage adjustments may be necessary when switching between buprenorphine products. Not all strengths and combinations of the buprenorphine and naloxone sublingual films are bioequivalent to buprenorphine and naloxone sublingual tablets as observed in pharmacokinetic studies [see Clinical Pharmacology ( 12.3 )] . Therefore, systemic exposures of buprenorphine and naloxone may be different when patients are switched from tablets to film or vice-versa. Patients should be monitored for symptoms related to over-dosing or under-dosing. 2.10 Switching Between Buprenorphine and Naloxone Sublingual Film Strengths As indicated in Table 1, the sizes and the compositions of the four units of buprenorphine and naloxone sublingual films, i.e., 2 mg/0.5 mg, 4 mg/1 mg, 8 mg/2 mg and the 12 mg/3 mg units, are different from one another. If patients switch between various combinations of lower and higher strength units of buprenorphine and naloxone sublingual films to obtain the same total dose, (e.g., from three 4 mg/1 mg units to a single 12 mg/3 mg unit, or vice-versa), systemic exposures of buprenorphine and naloxone may be different and patients should be monitored for over-dosing or under-dosing. For this reason, pharmacist should not substitute one or more film strengths for another without approval of the prescriber. Table 1. Comparison of Available Buprenorphine and Naloxone Sublingual Film Strengths by Dimensions and Drug Concentrations. Buprenorphine and naloxone sublingual film unit strength (buprenorphine and naloxone) Buprenorphine and naloxone sublingual film unit dimensions Buprenorphine Concentration % (w/w) Naloxone Concentration % (w/w) 2 mg/0.5 mg 22 mm x 12.8 mm 5.34 1.51 4 mg/1 mg (2 times the length of the 2 mg/0.5 mg unit) 22 mm x 25.6 mm 5.34 1.51 8 mg/2 mg 22 mm x 12.8 mm 17.10 4.84 12 mg/3 mg (1.5 times the length of the 8 mg/2 mg unit) 22 mm x 19.2 mm 17.10 4.84 2.11 Switching Between Sublingual and Buccal Sites of Administration The systemic exposure of buprenorphine between buccal and sublingual administration of buprenorphine and naloxone sublingual film is similar. Therefore, once induction is complete, patients can switch between buccal and sublingual administration without significant risk of under or overdosing.

4 CONTRAINDICATIONS Buprenorphine and naloxone sublingual film is contraindicated in patients with a history of hypersensitivity to buprenorphine or naloxone as serious adverse reactions, including anaphylactic shock, have been reported [see Warnings and Precautions ( 5.9 ) ] . Hypersensitivity to buprenorphine or naloxone. ( 4 )

6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Addiction, Abuse, and Misuse [see Warnings and Precautions ( 5.1 )] Respiratory and CNS Depression [see Warnings and Precautions ( 5.2 ) , ( 5.3 )] Neonatal Opioid Withdrawal Syndrome [see Warnings and Precautions ( 5.5 )] Adrenal Insufficiency [see Warnings and Precautions ( 5.6 )] Opioid Withdrawal [see Warnings and Precautions ( 5.7 , 5.10 )] Hepatitis, Hepatic Events [see Warnings and Precautions ( 5.8 )] Hypersensitivity Reactions [see Warnings and Precautions ( 5.9 )] Orthostatic Hypotension [see Warnings and Precautions ( 5.16 )] Elevation of Cerebrospinal Fluid Pressure [see Warnings and Precautions ( 5.17 )] Elevation of Intracholedochal Pressure [see Warnings and Precautions ( 5.18 )] Adverse events commonly observed with the sublingual/buccal administration of the buprenorphine and naloxone sublingual film are oral hypoesthesia, glossodynia, oral mucosal erythema, headache, nausea, vomiting, hyperhidrosis, constipation, signs and symptoms of withdrawal, insomnia, pain, and peripheral edema.

The safety of buprenorphine and naloxone sublingual film is supported by clinical trials using buprenorphine sublingual tablets and buprenorphine and naloxone sublingual tablets, and other trials using buprenorphine sublingual solutions, as well as an open-label study in 194 patients treated with buprenorphine and naloxone sublingual film administered sublingually and 188 patients treated with the film administered buccally. In total, safety data from clinical studies are available from over 3000 opioid-dependent subjects exposed to buprenorphine at doses in the range used in the treatment of opioid dependence. Few differences in the adverse event profile were noted with regard to sublingually and buccally administered buprenorphine and naloxone sublingual film, buprenorphine and naloxone sublingual tablets, buprenorphine sublingual tablets and a buprenorphine ethanolic sublingual solution. The most common adverse event (> 1%) associated with the sublingual administration of the buprenorphine and naloxone sublingual film was oral hypoesthesia. Other adverse events were constipation, glossodynia, oral mucosal erythema, vomiting, intoxication, disturbance in attention, palpitations, insomnia, withdrawal syndrome, hyperhidrosis, and blurred vision. The most common adverse events associated with the buccal administration were similar to those observed with sublingual administration of the film. Other adverse event data were derived from larger, controlled studies of buprenorphine and naloxone sublingual tablets and buprenorphine sublingual tablets and of buprenorphine sublingual solution. In a comparative study of buprenorphine and naloxone sublingual tablets and buprenorphine sublingual tablets, adverse event profiles were similar for subjects treated with 16 mg/4 mg buprenorphine and naloxone sublingual tablets or 16 mg buprenorphine sublingual tablets. The following adverse events were reported to occur by at least 5% of patients in a 4 week study of buprenorphine and naloxone sublingual tablets and buprenorphine sublingual tablets. Table 2.

Few differences in the adverse event profiles were noted between buprenorphine and naloxone sublingual film and the buprenorphine-only sublingual film. The most common adverse event occurring during treatment induction and the 3 days following induction using buprenorphine and naloxone sublingual film was restlessness. Other adverse events were anxiety, piloerection, stomach discomfort, irritability, headache, rhinorrhea, cold sweat, arthralgia, and lacrimation increased. Four subjects left the study early on the first day of sublingual film administration. However, there was no evidence to suggest that any of the four subjects experienced precipitated withdrawal secondary to the administration of buprenorphine or buprenorphine and naloxone sublingual films. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of buprenorphine and naloxone sublingual film. 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. The most frequently reported postmarketing adverse events were peripheral edema, stomatitis, glossitis, and blistering and ulceration of the mouth or tongue. 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 buprenorphine and naloxone sublingual film. Androgen deficiency: Cases of androgen deficiency have occurred with chronic use of opioids [see Clinical Pharmacology ( 12.2 )] . Local reactions: Dental decay (including caries, tooth fracture, and tooth loss), glossodynia, glossitis, oral mucosal erythema, oral hypoesthesia, and stomatitis. Hypoglycemia: Cases of hypoglycemia have been reported in patients taking opioids. Most reports were in patients with at least one predisposing risk factor (e.g., diabetes). Opioid-induced esophageal dysfunction (OIED) : Cases of OIED have been reported in patients taking opioids and may occur more frequently in patients taking higher doses of opioids, and/or in patients taking opioids longer term.
