`
` A marked and intense opioid withdrawal syndrome is highly
`
`
`likely to occur with parenteral misuse of SUBOXONE
`sublingual film by individuals physically dependent on full
`opioid agonists or by sublingual administration before the
`agonist effects of other opioids have subsided. (5.8)
` Neonatal withdrawal has been reported following use of
`buprenorphine by the mother during pregnancy. (5.9)
` SUBOXONE sublingual film is not appropriate as an
`
`analgesic. There have been reported deaths of opioid naïve
`individuals who received a 2 mg sublingual dose. (5.10)
` Caution patients about the risk of driving or operating
`
`hazardous machinery. (5.11)
`
`
`---------------------------ADVERSE REACTIONS--------------------------
`Adverse events commonly observed with the sublingual
`administration of the SUBOXONE sublingual film was oral
`hypoesthesia, glossodynia, oral mucosal erythema, headache,
`nausea, vomiting, hyperhidrosis, constipation, signs and
`symptoms of withdrawal, insomnia, pain, and peripheral edema.

`HIGHLIGHTS OF PRESCRIBING INFORMATION
`These highlights do not include all the information needed to use
`SUBOXONE® sublingual film safely and effectively. See full
`prescribing information for SUBOXONE sublingual film.
`SUBOXONE (buprenorphine and naloxone) sublingual film for
`sublingual administration CIII.
`
`
`
`
`Initial U.S. Approval: 2002
`
`-------------------------INDICATIONS AND USAGE-----------------------
`SUBOXONE sublingual film is indicated for maintenance
`treatment of opioid dependence. Prescription use of this product
`is limited under the Drug Addiction Treatment Act. (1)
`--------------------DOSAGE AND ADMINISTRATION-------------------
`Administer SUBOXONE sublingual film sublingually as a single
`daily dose. (2)
`The recommended daily dose for maintenance treatment is 16
`mg/4mg buprenorphine and naloxone. Advise patients not to cut,
`chew, or swallow SUBOXONE sublingual film
`-----------------DOSAGE FORMS AND STRENGTHS------------------
`Sublingual film: 2 mg buprenorphine with 0.5 mg naloxone, 4 mg
`
`buprenorphine with 1 mg naloxone ,8 mg buprenorphine with 2
`mg naloxone, and 12 mg buprenorphine with 3 mg naloxone. (3)
`--------------------------CONTRAINDICATIONS----------------------------
`Hypersensitivity to buprenorphine or naloxone. (4)
`-------------------WARNINGS AND PRECAUTIONS--------------------
` Buprenorphine can be abused in a similar manner to other
`
`opioids. 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. (5.1)
` Significant respiratory depression and death have occurred in
`
`
`association with buprenorphine, particularly when taken by
`
`the intravenous (IV) route in combination with
`benzodiazepines or other CNS depressants (including
`alcohol). (5.2)
` Consider dose reduction of CNS depressants, SUBOXONE
`sublingual film, or both in situations of concomitant
`prescription. (5.3)
` Store SUBOXONE sublingual film safely out of the sight and
`reach of children. Buprenorphine can cause severe, possibly
`
`fatal, respiratory depression in children. (5.4)
` Chronic administration produces opioid-type physical
`dependence. Abrupt discontinuation or rapid dose taper may
`result in opioid withdrawal syndrome. (5.5)
` Monitor liver function tests prior to initiation and during
`treatment and evaluate suspected hepatic events. (5.6)
` Do not administer SUBOXONE sublingual film to patients with
`known hypersensitivity to buprenorphine or naloxone. (5.7)

`
`
`FULL PRESCRIBING INFORMATION
`
`INDICATIONS AND USAGE
`1
`SUBOXONE sublingual film is indicated for maintenance 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
`
`SUBOXONE sublingual film is administered sublingually as a single daily dose. SUBOXONE sublingual film
`should be used in patients who have been initially inducted using SUBUTEX® (buprenorphine) sublingual tablets.
`
`
`2.1
`Maintenance
`
`
`
`
` SUBOXONE sublingual film is indicated for maintenance treatment. The recommended target dosage of
`
`
`SUBOXONE sublingual film is 16 mg/4 mg buprenorphine/naloxone/day as a single daily dose.
`
`
`
` The dosage of SUBOXONE sublingual film 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.
`
`
` 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.
`Dosages higher than this have not been demonstrated to provide any clinical advantage.
`
`
`
`2.2
`Method of Administration
`
`
`Do not cut, chew, or swallow SUBOXONE sublingual film. Place a sublingual film under the tongue. If an
`
`
`additional sublingual film is necessary to achieve the prescribed dose, place an 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
`2.3
`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).
`
`If treatment goals are not being achieved, the physician should re-evaluate the appropriateness of continuing the
`current treatment.
`
`Unstable Patients
`2.4
`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.
`
`
`2.5
`Stopping Treatment
`The decision to discontinue therapy with SUBOXONE sublingual film after a period of maintenance should be
`made as part of a comprehensive treatment plan. Both gradual and abrupt discontinuation of buprenorphine has
`been used, but the data are insufficient to determine the best method of dose taper at the end of treatment.
`
`Switching between SUBOXONE Sublingual Tablets and SUBOXONE Sublingual Film
`2.6
`Patients being switched between SUBOXONE sublingual tablets and SUBOXONE sublingual film should be
`started on the same dosage as 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 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 strips or vice-versa. Patients should be monitored for symptoms
`
`related to over-dosing or under-dosing.
`
`
`2.7
`Switching between SUBOXONE Sublingual Film strengths
`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/2 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.

`SUBOXONE sublingual film is supplied as an orange rectangular sublingual film with a white printed logo in four
`
`dosage strengths:
` buprenorphine/naloxone 2 mg/0.5 mg,
` buprenorphine/naloxone 4 mg/1 mg,
` buprenorphine/naloxone 8 mg/2 mg, and
`
` buprenorphine/naloxone 12 mg/3 mg

`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)].
`

`
`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)].
`
`
`
`5.2
`Respiratory Depression
`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)].
`
`
`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.
`
`
`5.5
`Dependence
`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 is 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 ne
