LONDON, Feb. 14, 2019 /PRNewswire/ --

Full Year 2018 Financial Highlights

• Net revenue of $1,005m, a decrease of 8% versus prior year (-9% at constant exchange). U.S. market growth was more than offset by U.S. SUBOXONE® Film share loss, targeted rebating and mix impact from growth in government channels (Medicaid).
• Operating profit was $292m (FY 2017: $193m). On an adjusted basis, FY 2018 operating profit was $332m, a decrease of 18% (Adj. FY 2017: $403m). Lower net revenue and higher SUBLOCADE™ and PERSERIS™ launch investments were partially offset by impacts from operating expense reductions.
• Net income was $275m (FY 2017: $58m). On an adjusted basis, FY 2018 net income was $272m +1% (Adj. FY 2017: $270m). Lower adjusted operating profit was more than offset by lower net financing costs and effective tax rate.  
• Cash balance at FY 2018 of $924m (+$61m). Net cash of $681m (+$305m). Voluntary repayments of $235m on the Term Loan were made in the period; $243m remains outstanding. 

Key Operating Developments

• U.S. SUBOXONE® Film market share averaged and exited FY 2018 at 53%.
• The Court of Appeals for the Federal Circuit (CAFC) has denied Indivior's motion for rehearing and rehearing en banc following the CAFC's ruling vacating the preliminary injunction (PI) granted against Dr. Reddy's Laboratories (DRL).  The CAFC has also denied Indivior's emergency motions with the CAFC to stay issuance of the mandate pending resolution of Indivior's appeal of the District of Delaware's decision finding DRL does not infringe U.S. Patent No. 8,603,514 ("the '514 patent"), and pending Indivior's forthcoming petition for a writ of certiorari to the Supreme Court of the United States in the PI matter. The CAFC has ordered issuance of the mandate on February 19, 2019. In response, Indivior will file a petition with the Supreme Court of the United States to stay the mandate pending the outcome of the forthcoming petition for certiorari seeking to overturn the CAFC's PI vacatur. If the mandate issues, Indivior assumes that DRL and Alvogen Pine Brook LLC will launch their generic buprenorphine/naloxone sublingual film products on an "at-risk" basis, leading to rapid and material loss of market share for SUBOXONE® Film. It is possible that other companies may also subsequently launch generic buprenorphine/naloxone sublingual film products on an "at-risk" basis. Indivior has been preparing for this eventuality and has implemented certain key elements of its contingency plan in light of these expected generic launches (see details on Page 2).
• SUBLOCADE™ net revenues were $12m, including $7m in Q4 2018. Key performance indicators (KPIs) continue to improve (see page 4).
• PERSERIS™ was made available in the U.S. in late November 2018. Commercial launch will take place the week of February 18, 2019 with a field force of 50 representatives.
• Reached a definitive agreement (February 4, 2019) to divest rights related to SUBOXONE® Sublingual Tablets (Sai Bo Song™) in the Peoples Republic of China to Zhejiang Pukang Biotechnology Co., Ltd. (Pukang) for total potential consideration of up to $122.5m based on achieving certain milestones. The agreement is subject to various closing conditions and is anticipated to close in Q4 2019.
• Termination of Arbaclofen Placarbil and ADDEX lead compound due to challenges in their Phase 1 and preclinical studies, respectively, reducing their probability of success below hurdle rates for further investment. This decision does not change our reason to believe in the molecular target (GABAb receptor) and plans are currently being put in place to accelerate our backup program (new lead identification and optimization) in partnership with ADDEX.
• The Group continues in advanced discussions with the U.S. Department of Justice (DOJ) about a possible resolution to its investigations. Please see Notes 8, 9 and 10 beginning on page 22 for further details on provisions and legal proceeding.

Contingency Plan
Indivior has implemented key elements of its contingency plan to help offset the substantial and material near-term impact to net revenue that is expected to result from the "at-risk" launch of generic versions of SUBOXONE® film. The overriding objectives of the contingency plan are to provide for the commercial success of SUBLOCADE™ and PERSERIS™ while ensuring a minimum cash balance of $250m to remain in compliance with the Group's debt covenants. Key actions include:

• Reducing outstanding principal on the Term Loan by $235m in FY 2018 to $243m;
• Cash conservation measures resulting in FY 2018 ending cash balance of $924m;
• Initiatives to reduce structural operating expenses, including headcount reductions, R&D reprioritization and other committed savings; and,
• Additionally, Indivior expects to launch an Authorized Generic of SUBOXONE® Film upon confirmation of the launch of generic buprenorphine/naloxone sublingual film products. The launch is expected to capture share of the generic segment and generate an amount of net revenue in the range of tens of U.S.$ millions.

FY 2019 Guidance
Given uncertainties surrounding how the U.S. market for both SUBOXONE® Film and generic alternatives will ultimately develop, Indivior is unable to provide FY 2019 net revenue and net income guidance at this time.

However, Indivior is providing guidance on the following elements of its business for FY 2019:

• SUBLOCADE net revenue of $50m to $70m; and,
• Operating expenses (SG&A and R&D combined) of approximately $440m to $460m, excluding exceptional items.

As discussed above, Indivior has executed key elements of its contingency plan. Its overriding objectives are to ensure a minimum cash balance of $250m to remain in compliance with its debt covenants and to help provide resources to cover the transition period of expected material and rapid loss of SUBOXONE® film net revenue in the U.S. until combined net revenue from SUBLOCADE™ and PERSERIS™, along with continued net revenue from the rest of world (ROW), is able to return the Group to profitable growth.

Indivior intends to provide FY 2019 Group net revenue and net income guidance (before exceptionals and currency) once the total U.S. buprenorphine/naloxone sublingual film market dynamics are clearer, which is anticipated to be at its Q1 2019 results release scheduled for May 2, 2019.  

Shaun Thaxter, CEO of Indivior, Commented:
"FY 2018 brought a series of market challenges which resulted in Indivior delivering lower net revenue and only slightly higher adjusted net income compared to the prior year. As we enter FY 2019, we assume we face the imminent "at-risk" launch of generic rivals to SUBOXONE® Film in the U.S. We have prudently prepared for this event, planning and taking the required actions to help ensure we can deliver on our strategic priorities despite the near-term top-line pressures that generic competition to SUBOXONE® Film will bring. Specifically, we have:

• Maintained our focus on cash generation and preserved our balance sheet;
• Continued to assert our IP against the ANDA filers;
• Completed steps that have appropriately adjusted our operating structure;
• Repaid $235m of outstanding Term Loan balance to lower the outstanding balance to $243m; and,
• Prepared the launch of an authorized generic of buprenorphine/naloxone sublingual film to participate in the rapidly forming generic market for buprenorphine/naloxone sublingual film.

"Together, these actions are designed to help us remain compliant with our borrowing covenants and help the Group to leverage the profitable long-term growth we expect from our new transformational depot technologies.

• In SUBLOCADE™, we are making progress toward a truly new treatment paradigm for OUD patients and the opioid crisis, and the coming year will see us further strengthen our execution in pursuit of our $1bn-plus net revenue target. With PERSERIS™ we believe we have a differentiated long-acting injectable treatment for schizophrenia, a common co-occurrence of substance use disorders, and the long-sought strategic opportunity we have created to diversify our revenue base. We are confident these products will be the future value drivers of Indivior and our focus in 2019 will be on their successful commercial execution.
• Of course, we could not drive these new launches, together with our base film and tablet business, without our talented and committed global workforce. We are truly grateful that – despite the recent period of disruption and uncertainty – the new organization that has emerged this year is energized and optimistic.
• Finally, in everything we do we think first and foremost about the patient. Our inspiration is to improve the lives of the many patients across all walks of society who suffer from the chronic relapsing conditions of addiction and its co-occurring disorders. This relentless patient-centricity, along with maintaining the highest regulatory and compliance standards, provides the foundational elements of Indivior's long-term success."

FY Operating Review

U.S. Market Update

In 2018, market volume for buprenorphine products continued to grow at low-teen percentage rates, in line with Indivior's expectations. This volume growth was driven by benefits from legislation and regulatory changes that have increased federal and state funding to expand OUD treatment, as well as from broader general awareness of the opioid epidemic.

Indivior supports the swift actions the U.S. government has taken to combat the opioid epidemic, including the recent enactment of the SUPPORT for Patients and Communities Act of 2018, which expands access to buprenorphine medication-assisted treatment (BMAT). These regulatory and legislative initiatives are supporting greater treatment capacity for those in most need and are likely to be manifested in continued growth in lower-priced government channels, such as Medicaid.

As the leader and innovator in the OUD category, Indivior has launched its new monthly buprenorphine depot SUBLOCADE™. The Group is making good progress in the following KPIs that it believes will drive accelerated net revenue growth for SUBLOCADE™ in pursuit of its $1 billion-plus peak net revenue goal:

SUBLOCADE™ Prescription Journey Timeline KPIs (12/31/18 vs. 9/30/18):

• Formulary Access – reached targeted levels, exiting FY 2018 at 83%.
• The Prescription Journey – reached targeted levels, exiting FY 2018 at 15 to 22 days.
• The Dispensing Yield Rate – increased to 41% from 38%.

SUBLOCADE™ Demand KPIs (12/31/18 vs. 9/30/18):

• HCPs Initiating a Prescription Journey – increased to 2,430 versus 1,870.
• HCPs Administered SUBLOCADE™ – increased to 1,325 versus 824.
• HCPs Administered SUBLOCADE™ to 5-plus patients increased to 232 versus 108.

FY 2018 & Q4 2018 Financial Performance

Total net revenue in FY 2018 decreased 8% to $1,005m (FY 2017: $1,093m) at actual exchange rates (-9% at constant exchange rates). In FY 2018, volume improvement from underlying market expansion in the U.S. and net revenue contribution from SUBLOCADE™ (FY 2018: $12m) were more than offset by the combined impacts of unfavorable mix from the increase in government channels (Medicaid) in the U.S., targeted rebating to maintain formulary access and a decline in SUBOXONE® Film market share. In Q4 2018, total net revenue decreased 11% at actual and 10% at constant exchange rates to $236m (Q4 2017: $265m). Along with higher SUBOXONE® Film stocking levels in the U.S. versus Q4 2017, Q4 2018 total net revenue drivers were substantially the same as those for FY 2018. Q4 2018 SUBLOCADE™ net revenue was $7m.

FY 2018 U.S. net revenue decreased 10% to $790m (FY 2017: $877m) and declined 12% in Q4 2018 to $182m (Q4 2017: $207m). For both comparative periods, volume benefits from underlying market growth were more than offset by the combined impacts of unfavorable mix from the continued disproportionate growth in government channels (Medicaid), targeted rebating to maintain formulary access and the decline in SUBOXONE® Film market share as a result of competitive pricing pressure from generic buprenorphine/naloxone tablet providers. Improved SUBOXONE® Film pricing was more than offset by tactical rebating activity in connection with formulary access. In Q4 2018, there was higher SUBOXONE® Film stocking levels in the U.S. versus Q4 2017 due to increased anticipation by distributor partners of an "at-risk" generic launch after the CAFC's decision on November 20, 2018, to vacate the preliminary injunction (PI) previously granted Indivior against DRL. This increase was more than offset by unfavorable mix and higher rebate rates as discussed for the full year.

FY 2018 ROW net revenue decreased 1% at actual exchange rates (3% at constant exchange rates) to $215m (FY 2017: $216m).  In Q4 2018, ROW net revenue decreased 7% at actual exchange rates (1% at constant exchange rates) to $54m (Q4 2017: $58m). For both comparative periods, continued growth in Australasia and Canada were more than offset by impacts in certain European markets from ongoing austerity measures.

FY 2018 gross margin was 87% (FY 2017: 90%) and the gross margin was also 85% in Q4 2018 (Q4 2017: 88%). The decrease in both periods versus the prior year primarily reflects lower net revenue driven by higher rebate rates and unfavorable mix and the impact of contingency planning for an "at-risk" launch of a generic buprenorphine/naloxone sublingual film product.

FY 2018 SG&A expenses as reported were $494m (FY 2017: $707m) and $140m in Q4 2018 (Q4 2017: $326m). FY 2018 SG&A included net exceptional costs of $16m. The exceptional costs comprised $13m related to restructuring and $40m related primarily to potential redress for ongoing intellectual property related litigation, partially offset by a $37m gain from the out-licensing of the intranasal naloxone opioid overdose patents. FY 2017 results included exceptional items of $210m for an increased legal provision related to investigative and antitrust litigation matters and the legal settlement of the Amneal antitrust matter, partially offset by the release of a legacy litigation reserve.

Q4 2018 SG&A included net exceptional costs of $34m. The exceptional costs comprised $13m related to restructuring and $40m related primarily to potential redress for ongoing intellectual property related litigation, partially offset by an exceptional gain of $19m related to a further payment for the intranasal naloxone opioid overdose patents as discussed above. Q4 2017 SG&A included total exceptional costs of $185m for the increased legal provision partially offset by the release of a legacy litigation reserve as described above.

On an adjusted basis, FY 2018 SG&A expenses decreased 4% to $478m (Adj. FY 2017: $497m) and in Q4 2018 SG&A expenses decreased by 25% to $106m (Adj. Q4 2017: $141m). The decrease in both periods largely reflects benefits from cost savings actions partially offset by the planned investments for launching SUBLOCADE™ and PERSERIS™.

Reported FY 2018 and Q4 2018 R&D expenses were $91m and $41m, respectively (FY 2017: $89m; Q4 2017: $22m). The increase was primarily driven by the Q4 2018 impairment of the Arbaclofen Placarbil and ADDEX lead compounds in development, which have been classified as exceptional items.  Excluding exceptionals, FY 2018 and Q4 2018 R&D expenses decreased by 25% to $67m and by 23% to $17m, respectively (Adj. FY 2017: $89m; Adj. Q4 2017: $22m). The decreases in both periods primarily reflect lower clinical activity and the reprioritization of R&D activities primarily to support SUBLOCADE™ Health Economics and Outcomes Research (HEOR) and post-marketing study commitments.

FY 2018 operating profit was $292m (FY 2017: $193m) and Q4 2018 operating profit was $20m (Q4 2017 operating loss: $115m). Exceptional costs of $40m and $210m are included in the FY 2018 and FY 2017 results, respectively. Exceptional costs of $58m and $185m are included in Q4 2018 and Q4 2017, respectively.

On an adjusted basis, FY 2018 operating profit was $332m (33% margin), an 18% decrease versus $403m (37% margin) in FY 2017.  The decrease reflects lower net revenue, launch investments for SUBLOCADE™ and PERSERIS™, partly offset by a reduction in operating expenses (SG&A and R&D) from cost savings initiatives. On an adjusted basis, Q4 2018 operating profit was $78m (33% margin), an 11% increase versus $70m (26% margin) in Q4 2017. The increase reflects benefits from cost savings initiatives that more than offset lower net revenue.

FY 2018 EBITDA (operating profit plus depreciation and amortization) was $308m (FY 2017: $206m). Excluding $40m and $210m of exceptional items in the current and year-ago results, respectively, FY 2018 adjusted EBITDA was $348m (Adj. FY 2017: $416m).

FY 2018 net finance expense was $14m (FY 2017: $56m) and nil in Q4 2018 (Q4 2017: $22m). The reduction in each period reflects lower interest and amortization of financing costs associated with the replacement of the Group's Term Loan borrowing facility in December 2017 and the voluntary repayments of $235m of the principal balance in the year ($85m in Q4 2018), and higher interest income.   

FY 2018 total tax expense was $3m, or a rate of 1% (FY 2017 tax charge: $79m; 58% rate). FY 2018 tax charge included one-time items related to development credits for SUBLOCADE™ of $34m, including $1m interest. FY 2017 full-year tax charge also assumed non-deductibility for tax purposes of the exceptional legal provisions and included $9m related to the release of provisions for unresolved tax matters, partially offset by the impact of the remeasurement of certain deferred tax assets. Excluding exceptional items in FY 2018 pre-tax income and taxation of $46m (FY 2017: $91m), the adjusted rate was 15% (Adj. FY 2017: 25%). The decrease in the adjusted rate was due to changes in the geographic mix of earnings, with increased earnings in the UK under the reduced rate for Patent Box, along with a reduction in the U.S. corporate income tax rate from 35% to 21%. Q4 2018 tax credit was $4m (Q4 2017 charge: $8m), or a rate of -20% (Q4 2017: 6%). Q4 2018 included a $10m tax impact on exceptional items and $5m of exceptional tax items; $2m relating to finalization of prior year US rate change and $3m to the finalization of prior year development credits for SUBLOCADE™ (Q4 2017: $6m release of provisions for unresolved tax matters fully offset by $6m of taxes on exceptional items).  The adjusted tax rate for the quarter was 14% (Q4 2017: 13%)

FY 2018 net income was $275m (FY 2017: $58m) as reported. Excluding exceptional costs, FY 2018 net income was broadly unchanged at $272m (Adj. FY 2017: $270m). The current and year-ago annual periods include a net amount of $3m and $212m of exceptional items, respectively. In Q4 2018, net income was $24m (Q4 2017 net loss: $145m). Excluding exceptional costs, net income for the Q4 was $67m (Adj. Q4 2017: $54m). Q4 2018 and Q4 2017 include a net $43m and $199m of exceptional items, respectively.

FY 2018 basic EPS was 38 cents (FY 2017: 8 cents) and 37 cents on a diluted basis (FY 2017: 8 cents). On an adjusted basis, excluding the effect of exceptional items, FY 2017 basic EPS was 37 cents (FY 2017: 37 cents) and diluted EPS was 36 cents (FY 2017: 36 cents).

Balance Sheet & Cash Flow

Cash and cash equivalents at the end of FY 2018 were $924m, an increase of $61m versus FY 2017 of $863m. Borrowings, net of issuance costs, were $241m at the end of the year (FY 2017: $482m), primarily reflecting the impact of the voluntary repayments of $235m of outstanding Term Loan principal in H2 2018. As a result, net cash stood at $681m at year end (FY 2017: $376), a $305m improvement in the year.

Net working capital (inventory plus trade and other receivables, less trade and other payables) was negative $356m at year end, an increase of $21m from negative $335m since the end of FY 2017 primarily driven by an increase in sales returns and rebates in the U.S. within payables, partially offset by increased inventories due in part to the launch of SUBLOCADE™.

Cash generated from operations in FY 2018 was $327m (FY 2017: $369m), a decrease of $42m. The reduction in cash generated versus the year-ago period was primarily due to higher operating profit more than offset by a lower increase in legal provisions versus the prior year, net of other working capital changes.

FY 2018 net cash inflow from operating activities was $303m (FY 2017: $295m), an increase of $8m reflecting lower cash from operations more than offset by lower net interest payments of $8m vs. $36m in the prior year and reduced tax payments of $16m vs. $33m in 2017.

FY 2018 cash outflow from investing activities was $4m (FY 2017: $43m), reflecting upfront payments for licensing arrangements with ADDEX and C4X, capitalized development costs, and ongoing investments in facilities, mostly offset by proceeds received from the disposal of the nasal naloxone intangible asset.

FY 2018 cash outflow from financing activities increased to $237m vs. $84m in FY 2017, primarily reflecting the impact of the voluntary repayments of $235m of the outstanding Term Loan balance in H2 2018.

Risk Factors
The Board of Directors has carried out a robust assessment to ensure that the Principal Risks, including those that would threaten the Group's business model, future performance, solvency or liquidity are effectively managed and/or mitigated to help ensure the Group remains viable. While the Group aims to identify and manage such risks, no risk management strategy can provide absolute assurance against loss.

Set out below are what the Group considers to be the principal risks that could cause the Group's business model, future performance and solvency or liquidity to differ materially from expected and historical results. Additional risks, not listed here, that the Group cannot presently identify or does not believe to be equally significant, may materially and adversely affect the business, results of operations and financial position. The principal risk factors and uncertainties are not listed in order of significance.

Business operations

• The Group's operations rely on complex processes and systems, strategic partnerships, as well as specially qualified and high performing personnel to develop, manufacture and sell our products. Failure to continuously maintain operational processes and systems as well as to recruit and/or retain qualified personnel could adversely impact products availability and patient health, and ultimately the Group's performance and financials. Additionally, an ever evolving regulatory, political and technological landscape requires that we have the right priorities, capabilities and structures in place to successfully execute on our business strategy and adapt to this changing environment. An example of this evolving landscape is Brexit (decision for the UK to leave the EU), which creates uncertainties and impacts various areas of the Group, including Operations, Regulatory, Supply Chain, and Quality. 

Product pipeline, regulatory and safety

• The development and approval of the Group's products is an inherently risky and lengthy process requiring significant financial, research and development resources, and strategic partnerships.  Complex regulations with strict and high safety standards govern the development, manufacturing, and distribution of our products. In addition, strong competition exists for strategic collaboration, licensing arrangements, and acquisition targets. Patient safety depends on our ability to perform robust safety assessment and interpretation to ensure that appropriate decisions are made regarding to the benefit/risk profiles of our products. Deviations from these quality and safety practices can impact patient safety and market access, which can have a material effect on our Group's performance and prospects.

Commercialization

• Successful commercialization of our products is a critical factor for the Group's sustained growth and robust financial position. Launch of new product involves substantial investment in marketing, market access and sales activities, product stocks, and other investments. If commercialization of a new product is not as successful as anticipated this could have a material impact on the Group's performance and prospects. Generic and brand competition, pricing pressures, private and government reimbursement schemes and systems, negotiations with payors, erosion and/or infringement of intellectual property (IP) rights, political and socioeconomic factors and HCP/Patient adoption and adherence, if different than anticipated, also can significantly impact the Group's performance and position.

Economic & Financial

• The nature of the pharmaceutical business is inherently risky and uncertain and requires that we make significant financial investments to develop and support the success of our product portfolio. External financing is a key factor in sustaining our financial position and expanding our business growth. Our ability to realize value on those investments is often dependent upon regulatory approvals, market acceptance, strategic partnerships, competition, and legal developments. As a global business, we are also subject to political, economic, and capital markets changes.

Supply Chain

• The manufacturing and supply of our products are highly complex and rely on a combination of internal manufacturing capabilities and third parties for the timely supply of our finished drug and combination drug products. The Group has a single source of supply for buprenorphine, an active product ingredient (API) in the Group's products, and uses contract manufacturing organizations (CMOs) to manufacture, package and distribute our products. The manufacturing of non-sterile pharmaceutical and sterile filled, pharma/combination drug products is subject to stringent global regulatory quality and safety standards, including Good Manufacturing Practice (GMP). Delays or interruptions in our supply chain, and/or product quality failures could significantly disrupt patient access, adversely impact the Group's financial performance; lead to product recalls, and/or potential regulatory actions against the company, along with reputational damages.

Legal & Intellectual Property

• Our pharmaceutical operations, which include controlled substances, are subject to a wide range of laws and regulations from various governmental and non-governmental bodies.  Perceived noncompliance with these applicable laws and regulations may result in investigations or proceedings leading the Group to become subject to civil or criminal sanctions and/or pay fines and/or damages, as well as reputational damages.
• Intellectual Property (IP) rights protecting our products may be challenged by external parties, including generic manufacturers.  Although we have developed robust patent protection for our products, we are exposed to the risk that courts may decide that our IP rights are invalid and/or that third parties do not infringe our asserted IP rights. 
• Unfavorable outcome from government investigations and/or resolutions from legal proceedings, expiry and/or loss of IP rights could have a material adverse impact on the Group's prospects, results of operations and financial condition.
• As previously disclosed in the Prospectus dated November 17, 2014, Indivior has indemnification obligations in favor of Reckitt Benckiser (RB). See further information on legal proceedings in note 10 on pages 23 to 25.

Compliance Product Safety

• Our Group operates on a global basis and the pharmaceutical industry is both highly competitive and regulated.  Complying with all applicable laws and regulations, including engaging in commercial activities that are consistent with legal and, industry standards, and our Group's Code of Conduct are core to the Group's mission, culture, and practices. Failure to comply with applicable laws and regulations may subject the Group to civil, criminal and administrative liability, including the imposition of substantial monetary penalties, fines, damages and restructuring the Group's operations through the imposition of compliance or integrity obligations and have a potential adverse impact on the Group's prospects, reputation, results of operations and financial condition.

The Group's annual report for the 2018 financial year will contain additional detail on these principal business risks together with a report on risk appetite.

SUBOXONE® (BUPRENORPHINE AND NALOXONE) SUBLINGUAL FILM (CIII)

Indication
SUBOXONE^® (buprenorphine and naloxone) Sublingual Film (CIII) is a prescription medicine indicated for treatment of opioid dependence and should be used as part of a complete treatment plan to include counseling and psychosocial support.
Treatment should be initiated under the direction of healthcare providers qualified under the Drug Addiction Treatment Act.

Important Safety Information

Do not take SUBOXONE® Film if you are allergic to buprenorphine or naloxone as serious negative effects, including anaphylactic shock, have been reported.

SUBOXONE® Film can be abused in a manner similar to other opioids, legal or illicit.

SUBOXONE® Film contains buprenorphine, an opioid that can cause physical dependence with chronic use. Physical dependence is not the same as addiction. Your healthcare provider can tell you more about the difference between physical dependence and drug addiction. Do not stop taking SUBOXONE® Film suddenly without talking to your healthcare provider. You could become sick with uncomfortable withdrawal symptoms because your body has become used to this medicine.

SUBOXONE® Film can cause serious life-threatening breathing problems, overdose and death, particularly when taken by the intravenous (IV) route in combination with benzodiazepines or other medications that act on the nervous system (ie, sedatives, tranquilizers, or alcohol). It is extremely dangerous to take nonprescribed benzodiazepines or other medications that act on the nervous system while taking SUBOXONE® Film.

You should not drink alcohol while taking SUBOXONE® Film, as this can lead to loss of consciousness or even death.

Death has been reported in those who are not opioid dependent.

Your healthcare provider may monitor liver function before and during treatment.

SUBOXONE® Film is not recommended in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment. However, SUBOXONE® Film may be used with caution for maintenance treatment in patients with moderate hepatic impairment who have initiated treatment on a buprenorphine product without naloxone.

Keep SUBOXONE® Film out of the sight and reach of children. Accidental or deliberate ingestion of SUBOXONE® Film by a child can cause severe breathing problems and death.

Do not take SUBOXONE® Film before the effects of other opioids (eg, heroin, hydrocodone, methadone, morphine, oxycodone) have subsided as you may experience withdrawal symptoms.

Injecting the SUBOXONE® Film product may cause serious withdrawal symptoms such as pain, cramps, vomiting, diarrhea, anxiety, sleep problems, and cravings.

Before taking SUBOXONE® Film, tell your healthcare provider if you are pregnant or plan to become pregnant. If you are pregnant, tell your healthcare provider as withdrawal signs and symptoms should be monitored closely and the dose adjusted as necessary. If you are pregnant or become pregnant while taking SUBOXONE® Film, alert your healthcare provider immediately and you should report it using the contact information provided below.
