`FULL PRESCRIBING INFORMATION
`
`INDICATIONS AND USAGE
`1
`SUBOXONE sublingual film is indicated for treatment of opioid dependence and should be used as part of a
`complete treatment plan to include counseling and psychosocial support.
`Under the Drug Addiction Treatment Act (DATA) codified at 21 U.S.C. 823(g), prescription use of this product
`in the treatment of opioid dependence is limited to physicians who meet certain qualifying requirements,
`and who have notified the Secretary of Health and Human Services (HHS) of their intent to prescribe this
`product for the treatment of opioid dependence and have been assigned a unique identification number that
`must be included on every prescription.
`
`DOSAGE AND ADMINISTRATION
`2
`Induction
`2.1
`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. To avoid
`precipitating an opioid withdrawal syndrome, the first dose of buprenorphine/naloxone should be started only
`when objective signs of moderate withdrawal appear.
`
`On Day 1, an induction dosage of up to 8 mg /2 mg SUBOXONE sublingual film is recommended. Clinicians
`should start with an initial dose of 2 mg/ 0.5 mg or 4 mg/1 mg buprenorphine/naloxone and may titrate
`upwards in 2 or 4 mg increments of buprenorphine, at approximately 2-hour intervals, under supervision, to 8
`mg/2 mg buprenorphine/naloxone based on the control of acute withdrawal symptoms.
`On Day 2, a single daily dose of up to 16 mg/4 mg SUBOXONE sublingual film is recommended.
`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.
`
`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/naloxone combination products have not been evaluated in adequate and well-controlled
`studies for induction in patients on long-acting opioid products, and contain naloxone, which 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 SUBOXONE sublingual film.
`
`Patients dependent on heroin or other short-acting opioid products
`
`Patients dependent on heroin or short-acting opioid products may be inducted with either SUBOXONE sublingual
`film or with sublingual buprenorphine monotherapy. The first dose of SUBOXONE sublingual film or
`buprenorphine should be administered when objective signs of moderate opioid withdrawal appear, and not less
`than 6 hours after the patient last used an opioid.
`
`It is recommended that an adequate maintenance 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.
`
`
`Reference ID: 3496928
`
`Page 3
`
`
`
`Maintenance
`2.2
`The dosage of SUBOXONE 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/naloxone to a level that holds the patient
`in treatment and suppresses opioid withdrawal signs and symptoms.
`
`After treatment induction and stabilization, the maintenance dose of SUBOXONE sublingual film is generally in
`the range of 4 mg/1 mg buprenorphine/naloxone to 24 mg/6 mg buprenorphine/naloxone per day depending on
`the individual patient and clinical response. The recommended target dosage of SUBOXONE sublingual film
`during maintenance is 16 mg/4 mg buprenorphine/naloxone/day as a single daily dose. Dosages higher than 24
`mg/6 mg daily have not been demonstrated to provide a clinical advantage.
`
`Method of Administration
`2.3
`Do not cut, chew, or swallow SUBOXONE sublingual film. Place the SUBOXONE sublingual film under the tongue,
`close to the base on the left or right side. If an additional sublingual film is necessary to achieve the prescribed
`dose, place the additional sublingual film sublingually on the opposite side from the first film. Place the sublingual
`film in a manner to minimize overlapping as much as possible. The sublingual film must be kept under the tongue
`until the film is completely dissolved. SUBOXONE sublingual film should NOT be moved after placement. Proper
`administration technique should be demonstrated to the patient.
`
`Clinical Supervision
`2.4
`Treatment should be initiated with supervised administration, progressing to unsupervised administration as
`the patient’s clinical stability permits. SUBOXONE 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 physician’s evaluation of
`treatment outcomes and objectives such as:
`
`1. Absence of medication toxicity.
`
`2. Absence of medical or behavioral adverse effects.
`
`3. Responsible handling of medications by the patient.
`
`4. Patient’s compliance with all elements of the treatment plan (including recovery-oriented activities,
`psychotherapy, and/or other psychosocial modalities).
`
`
`5. Abstinence from illicit drug use (including problematic alcohol and/or benzodiazepine use).
`
`
`Reference ID: 3496928
`
`Page 4
`
`
`
`If treatment goals are not being achieved, the physician should re-evaluate the appropriateness of continuing
`the current treatment.
`
`Patients With Hepatic Impairment
`2.5
`Because the doses of this fixed combination product cannot be individually titrated, severe hepatic impairment
`results in a reduced clearance of naloxone to a much greater extent than buprenorphine, and moderate
`hepatic impairment also results in a reduced clearance of naloxone to a greater extent than buprenorphine,
`the combination product should generally be avoided in patients with severe hepatic impairment and may not
`be appropriate for patients with moderate hepatic impairment [see Warnings and Precautions (5.11)].
`
`Unstable Patients
`2.6
`Physicians 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 physician does not feel that he/she has the expertise to manage the
`patient. In such cases, the physician 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.
`
`Stopping Treatment
`2.7
`The decision to discontinue therapy with SUBOXONE sublingual film after a period of maintenance should be
`made as part of a comprehensive treatment plan. Taper patients to avoid opioid withdrawal signs and
`symptoms.
`
`Switching Between Buprenorphine or Buprenorphine and Naloxone Sublingual Tablets and
`2.8
`SUBOXONE Sublingual Film
`Patients being switched between buprenorphine and naloxone or buprenorphine only sublingual tablets and
`SUBOXONE sublingual film should be started on the corresponding dosage of the previously administered
`product. However, dosage adjustments may be necessary when switching between products. Not all strengths
`and combinations of the SUBOXONE sublingual films are bioequivalent to the SUBOXONE (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.
`
`Switching Between SUBOXONE Sublingual Film Strengths
`2.9
`As indicated in Table 1, the sizes and the compositions of the four units of SUBOXONE 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 SUBOXONE 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.

`
`CONTRAINDICATIONS
`4
`SUBOXONE sublingual film should not be administered to patients who have been shown to be hypersensitive
`to buprenorphine or naloxone as serious adverse reactions, including anaphylactic shock, have been reported
`[see Warnings and Precautions (5.7)].
`
`5
`
`WARNINGS AND PRECAUTIONS
`
`Abuse Potential
`5.1
`Buprenorphine can be abused in a manner similar to other opioids, legal or illicit. Prescribe and dispense
`buprenorphine with appropriate precautions to minimize risk of misuse, abuse, or diversion, and ensure
`appropriate protection from theft, including in the home. Clinical monitoring appropriate to the patient’s level
`of stability is essential. Multiple refills should not be prescribed early in treatment or without appropriate
`patient follow-up visits [see Drug Abuse and Dependence (9.2)].
`
`Respiratory Depression
`5.2
`Buprenorphine, particularly when taken by the IV route, in combination with benzodiazepines or other CNS
`depressants (including alcohol), has been associated with significant respiratory depression and death. Many,
`but not all, post-marketing reports regarding coma and death associated with the concomitant use of
`buprenorphine and benzodiazepines involved misuse by self-injection. Deaths have also been reported in
`association with concomitant administration of buprenorphine with other depressants such as alcohol or other
`CNS depressant drugs. Patients should be warned of the potential danger of self-administration of
`benzodiazepines or other depressants while under treatment with SUBOXONE sublingual film [see Drug
`Interactions (7.3)].
`
`Reference ID: 3496928
`
`Page 6
`
`
`
`In the case of overdose, the primary management should be the re-establishment of adequate ventilation
`with mechanical assistance of respiration, if required. Naloxone may be of value for the management of
`buprenorphine overdose. Higher than normal doses and repeated administration may be necessary.
`SUBOXONE sublingual film should be used with caution in patients with compromised respiratory function
`(e.g., chronic obstructive pulmonary disease, cor pulmonale, decreased respiratory reserve, hypoxia,
`hypercapnia, or pre-existing respiratory depression).
`
`CNS Depression
`5.3
`Patients receiving buprenorphine in the presence of opioid analgesics, general anesthetics, benzodiazepines,
`phenothiazines, other tranquilizers, sedative/hypnotics, or other CNS depressants (including alcohol) may
`exhibit increased CNS depression. Consider dose reduction of CNS depressants, SUBOXONE sublingual film, or
`both in situations of concomitant prescription [see Drug Interactions (7.3)].
`
`Unintentional Pediatric Exposure
`5.4
`Buprenorphine can cause severe, possibly fatal, respiratory depression in children who are accidentally
`exposed to it. Store buprenorphine-containing medications safely out of the sight and reach of children.
`
`Dependence
`5.5
`Buprenorphine is a partial agonist at the mu-opioid receptor and chronic administration produces physical
`dependence of the opioid type, characterized by withdrawal signs and symptoms upon abrupt discontinuation
`or rapid taper. The withdrawal syndrome is typically milder than seen with full agonists and may be delayed in
`onset. Buprenorphine can be abused in a manner similar to other opioids. This should be considered when
`prescribing or dispensing buprenorphine in situations when the clinician is concerned about an increased risk
`of misuse, abuse, or diversion [see Drug Abuse and Dependence (9.3)].
`
`Hepatitis, Hepatic Events
`5.6
`Cases of cytolytic hepatitis and hepatitis with jaundice have been observed in individuals receiving
`buprenorphine in clinical trials and through post-marketing adverse event reports. The spectrum of
`abnormalities ranges from transient asymptomatic elevations in hepatic transaminases to case reports of
`death, hepatic failure, hepatic necrosis, hepatorenal syndrome, and hepatic encephalopathy. In many cases,
`the presence of pre-existing liver enzyme abnormalities, infection with hepatitis B or hepatitis C virus,
`concomitant usage of other potentially hepatotoxic drugs, and ongoing injecting drug use may have played a
`causative or contributory role. In other cases, insufficient data were available to determine the etiology of the
`abnormality. Withdrawal of buprenorphine has resulted in amelioration of acute hepatitis in some cases;
`however, in other cases no dose reduction was necessary. The possibility exists that buprenorphine had a
`causative or contributory role in the development of the hepatic abnormality in some cases. Liver function
`tests, prior to initiation of treatment are recommended to establish a baseline. Periodic monitoring of liver
`function during treatment is also recommended. A biological and etiological evaluation is recommended when
`a hepatic event is suspected. Depending on the case, SUBOXONE sublingual film may need to be carefully
`discontinued to prevent withdrawal signs and symptoms and a return by the patient to illicit drug use, and
`strict monitoring of the patient should be initiated.
`
`Allergic Reactions
`5.7
`Cases of hypersensitivity to buprenorphine and naloxone containing products have been reported both in
`clinical trials and in the post-marketing experience. Cases of bronchospasm, angioneurotic edema, and
`anaphylactic shock have been reported. The most common signs and symptoms include rashes, hives, and
`pruritus. A history of hypersensitivity to buprenorphine or naloxone is a contraindication to the use of
`SUBOXONE sublingual film.
`
`Reference ID: 3496928
`
`Page 7
`
`
`
`Precipitation of Opioid Withdrawal Signs and Symptoms
`5.8
`Because it contains naloxone, SUBOXONE sublingual film is likely to produce withdrawal signs and symptoms if
`misused parenterally by individuals dependent on full opioid agonists such as heroin, morphine, or methadone.
`Because of the partial agonist properties of buprenorphine, SUBOXONE sublingual film may precipitate opioid
`withdrawal signs and symptoms in such persons if administered sublingually before the agonist effects of the
`opioid have subsided.
`
`Neonatal Withdrawal
`5.9
`Neonatal withdrawal has been reported in the infants of women treated with buprenorphine during
`pregnancy. From post-marketing reports, the time to onset of neonatal withdrawal signs ranged from Day 1 to
`Day 8 of life with most cases occurring on Day 1. Adverse events associated with the neonatal withdrawal
`syndrome included hypertonia, neonatal tremor, neonatal agitation, and myoclonus, and there have been
`reports of convulsions, apnea, respiratory depression, and bradycardia.
`
`5.10 Use in Opioid Naïve Patients
`There have been reported deaths of opioid naive individuals who received a 2 mg dose of buprenorphine as a
`sublingual tablet for analgesia. SUBOXONE sublingual film is not appropriate as an analgesic.
`
`5.11 Use in Patients With Impaired Hepatic Function
`Buprenorphine/naloxone products are not recommended in patients with severe hepatic impairment and may
`not be appropriate for patients with moderate hepatic impairment. Because hepatic impairment results in a
`reduced clearance of naloxone to a much greater extent than buprenorphine, the doses of buprenorphine and
`naloxone in this fixed-dose combination product cannot be individually titrated. Therefore, patients with
`severe hepatic impairment will be exposed to substantially higher levels of naloxone than patients with normal
`hepatic function. This may result in an increased risk of precipitated withdrawal at the beginning of treatment
`(induction) and may interfere with buprenorphine’s efficacy throughout treatment. In patients with moderate
`hepatic impairment, the differential reduction of naloxone clearance compared to buprenorphine clearance is
`not as great as in subjects with severe hepatic impairment. Therefore, buprenorphine/naloxone products are
`not recommended for initiation of treatment (induction) in patients with moderate hepatic impairment due to
`the increased risk of precipitated withdrawal. However, buprenorphine/naloxone products may be used with
`caution for maintenance treatment in patients with moderate hepatic impairment who have initiated
`treatment on a buprenorphine product without naloxone. However, patients should be carefully monitored
`and consideration given to the possibility of naloxone interfering with buprenorphine’s efficacy [see Use in
`Specific Populations (8.6)].
`
`Impairment of Ability to Drive or Operate Machinery
`5.12
`SUBOXONE sublingual film may impair the mental or physical abilities required for the performance of
`potentially dangerous tasks such as driving a car or operating machinery, especially during treatment induction
`and dose adjustment. Patients should be cautioned about driving or operating hazardous machinery until they
`are reasonably certain that SUBOXONE sublingual film therapy does not adversely affect his or her ability to
`engage in such activities.
`
`5.13 Orthostatic Hypotension
`Like other opioids, SUBOXONE sublingual film may produce orthostatic hypotension in ambulatory patients.
`
`Elevation of Cerebrospinal Fluid Pressure
`5.14
`Buprenorphine, like other opioids, may elevate cerebrospinal fluid pressure and should be used with caution in
`patients with head injury, intracranial lesions, and other circumstances when cerebrospinal pressure may be
`
`Reference ID: 3496928
`
`Page 8
`
`
`
`increased. Buprenorphine can produce miosis and changes in the level of consciousness that may interfere
`with patient evaluation.
`
`Elevation of Intracholedochal Pressure
`5.15
`Buprenorphine has been shown to increase intracholedochal pressure, as do other opioids, and thus should be
`administered with caution to patients with dysfunction of the biliary tract.
`
`Effects in Acute Abdominal Conditions
`5.16
`As with other opioids, buprenorphine may obscure the diagnosis or clinical course of patients with acute
`abdominal conditions.
`
`5.17 General Precautions
`SUBOXONE sublingual film should be administered with caution in debilitated patients and those with
`myxedema or hypothyroidism, adrenal cortical insufficiency (e.g., Addison's disease); CNS depression or coma;
`toxic psychoses; prostatic hypertrophy or urethral stricture; acute alcoholism; delirium tremens; or
`kyphoscoliosis.
`
`ADVERSE REACTIONS
`6
`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.
`
`Clinical Trials Experience
`6.1
`The safety of SUBOXONE sublingual film is supported by clinical trials using SUBUTEX (buprenorphine)
`sublingual tablets and SUBOXONE (buprenorphine and naloxone) sublingual tablets, and other trials using
`buprenorphine sublingual solutions, as well as an open-label study in 194 patients treated with SUBOXONE
`sublingual film. 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 among SUBOXONE sublingual film, SUBOXONE
`(buprenorphine and naloxone) sublingual tablets, SUBUTEX (buprenorphine) sublingual tablets and a
`buprenorphine ethanolic sublingual solution.
`The most common adverse event (>1%) associated with the sublingual administration of the SUBOXONE
`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.
`Other adverse event data were derived from larger, controlled studies of SUBOXONE (buprenorphine and
`naloxone) and SUBUTEX (buprenorphine) tablets and of buprenorphine sublingual solution. In a comparative
`study of SUBOXONE (buprenorphine and naloxone) and SUBUTEX (buprenorphine) sublingual tablets, adverse
`event profiles were similar for subjects treated with 16 mg/4 mg SUBOXONE (buprenorphine and naloxone)
`sublingual tablets or 16 mg SUBUTEX (buprenorphine) sublingual tablets. The following adverse events were
`reported to occur by at least 5% of patients in a 4 week study of SUBOXONE (buprenorphine and naloxone)
`sublingual tablets and SUBUTEX (buprenorphine) sublingual tablets.
