*Hypothetical patient. This is part of a sample summary and may not necessarily include a thorough patient assessment of all treatments (non-pharmacologic and/or pharmacologic) for chronic pain and/or other medical conditions.

Why Pam may be appropriate for Butrans

Butrans may be appropriate for patients with or without opioid experience, with pain severe enough to require a daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

Once you have determined that Pam meets the full Indications and Usage for Butrans, you should also take into consideration the Contraindications, Warnings and Precautions, and other elements of the Full Prescribing Information to determine if Pam is an appropriate candidate for Butrans.

Once you determine that Pam is appropriate for Butrans:

  • Use the lowest effective dosage for the shortest duration consistent with Kathy’s treatment goals

  • Initiate the dosing regimen for Pam individually, taking into account Pam’s severity of pain, patient response, prior analgesic treatment experience and risk factors for addiction, abuse, and misuse

  • Monitor Pam closely for respiratory depression, especially within the first 24 to 72 hours of initiating therapy with Butrans and following dosage increases

  • Butrans should be prescribed only by healthcare professionals who are knowledgeable in the use of potent opioids for the management of chronic pain

  • Butrans doses of 7.5, 10, 15, and 20 mcg/hour are only for use in patients who are opioid experienced and in whom tolerance to an opioid of comparable potency has been established. Patients who are opioid-experienced are those receiving, for one week or longer, daily opioid doses up to 80 mg/day of oral morphine or an equianalgesic dose of another opioid

  • Instruct patients not to use Butrans if the pouch seal is broken or the patch is cut, damaged, or changed in any way and not to cut Butrans

  • Instruct patients to avoid exposing Butrans to external heat sources, hot water, or prolonged direct sunlight

  • Butrans is for transdermal use (on intact skin) only

  • Each Butrans patch is intended to be worn for 7 days

Pam’s recommended starting dose for Butrans, her first opioid analgesic

  • Pam has no history of treatment with opioid analgesics for her chronic low back pain

  • According to the Full Prescribing Information, the recommended starting dose for patients taking NSAIDs, APAP, or other non-opioid analgesics with pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate is Butrans 5 mcg/hour

  • In a Butrans clinical trial with opioid-naïve patients like Pam, non-opioid analgesics used prior to enrollment included ibuprofen, acetaminophen, and naproxen1


To help Pam administer her first Butrans dose properly, a healthcare professional instructs her, step-by-step, on patch application.

Use of Butrans in patients with renal impairment

  • Pam’s medical chart included “moderate renal impairment”

  • No dose adjustments for patients with renal impairment are noted in the Full Prescribing Information

  • No studies in patients with renal impairment have been performed with Butrans. However, no notable relationship was observed between estimated creatinine clearance rates and steady-state buprenorphine concentrations among patients during Butrans therapy.

  • In an independent study, the effect of impaired renal function on buprenorphine pharmacokinetics after IV bolus and after continuous IV infusion administrations was evaluated. It was found that plasma buprenorphine concentrations were similar in patients with normal renal function and in patients with impaired renal function or renal failure.

  • In a separate investigation of the effect of intermittent hemodialysis on buprenorphine plasma concentrations in chronic pain patients with end-stage renal disease who were treated with a transdermal buprenorphine product (marketed outside the US) up to 70 mcg/hour, no significant differences in buprenorphine plasma concentrations before or after hemodialysis were observed.

For information on use of Butrans in geriatric patients or patients with hepatic impairment, see Patient Selection.

Continuing Pam’s treatment with Butrans

  • Continually reevaluate patients receiving Butrans to assess the maintenance of pain control and the relative incidence of adverse reactions, as well as monitoring for the development of addiction, abuse, or misuse

  • During chronic therapy, periodically reassess the continued need for opioid analgesics

  • Individually titrate Butrans to a dose that provides adequate analgesia and minimizes adverse reactions

  • The minimum Butrans titration interval is 72 hours, based on the pharmacokinetic profile and time to reach steady-state levels

  • If Pam experiences breakthrough pain, she may require a dosage adjustment increase of Butrans or may need rescue medication with an appropriate dose of an immediate-release analgesic (opioid or non-opioid). If the level of pain increases after dose stabilization, attempt to identify the source of increased pain before increasing the Butrans dose

  • The maximum Butrans dose is 20 mcg/hour. Do not exceed a dose of one 20 mcg/hour Butrans system due to the risk of QTc interval prolongation

Follow-up with Pam: decision to titrate her dose of Butrans

Follow up with Pam to ensure that her starting dose of Butrans 5 mcg/hour is providing adequate analgesia with minimal adverse reactions.

  • During a follow-up phone call, you learn that Pam is still experiencing pain in her lower back

  • Once you confirm that at least 3 days have passed since starting Butrans, you decide to titrate her dose of Butrans to 10 mcg/hour

  • You also consider prescribing an immediate-release analgesic (opioid or non-opioid) for breakthrough pain, if needed

  • Making dose adjustments with 2 patches

    • Since her first Butrans prescription was supplied with 4 Butrans 5 mcg/hour patches, you instruct her to titrate to a 10 mcg/hour dose by applying 2 of her remaining 5 mcg/hour patches. Total dose from 2 patches should not exceed 20 mcg/hour

    • For Pam to use 2 patches, you instruct her to remove her current patch, and apply the 2 new patches at the same time, adjacent to one another, at a different application site as explained in the Full Prescribing Information

    • If unacceptable opioid-related adverse events are observed, consider reducing the dosage

Adjust the dosage to obtain an appropriate balance between the management of pain and opioid-related adverse reactions.

How to discontinue when Pam no longer requires Butrans therapy

Discontinuation of therapy with Butrans

  • Use a gradual downward titration of the dose every 7 days, while monitoring carefully for signs and symptoms of withdrawal

  • If Pam develops these signs or symptoms, consider introduction of an appropriate immediate-release opioid medication

  • Do not abruptly discontinue Butrans

Butrans is the only Schedule III transdermal extended-release opioid

  • As a Schedule III opioid, prescriptions can be2:

    • Called in or faxed to your patients’ pharmacy, when appropriate

    • Authorized for up to 5 refills within 6 months before a new prescription is required*

    • Filled by mail-order pharmacies

  • Butrans has an abuse potential similar to other Schedule III opioids

  • Butrans can be abused and is subject to misuse, addiction, and criminal diversion. The high drug content in extended-release formulations adds to the risk of adverse outcomes from abuse and misuse

  • Butrans is subject to the same requirements of the class Risk Evaluation and Mitigation Strategy (REMS) for all Extended-Release and Long-Acting (ER/LA) opioid analgesics

*Refills may vary from state to state; please check with state guidelines.

Patients should verify with their mail-order pharmacies, as policies may vary.

Butrans has over 5 years of clinical experience3

WARNING: ADDICTION, ABUSE and MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL EXPOSURE; NEONATAL OPIOID WITHDRAWAL SYNDROME; and RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS

Addiction, Abuse, and Misuse

Butrans exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient’s risk prior to prescribing Butrans, and monitor all patients regularly for the development of these behaviors and conditions [see Warnings and Precautions (5.1) and Overdosage (10)].

Life-Threatening Respiratory Depression

Serious, life-threatening, or fatal respiratory depression may occur with use of Butrans. Monitor for respiratory depression, especially during initiation of Butrans or following a dose increase. Misuse or abuse of Butrans by chewing, swallowing, snorting or injecting buprenorphine extracted from the transdermal system will result in the uncontrolled delivery of buprenorphine and pose a significant risk of overdose and death [see Warnings and Precautions (5.2)].

Accidental Exposure

Accidental exposure to even one dose of Butrans, especially in children, can result in a fatal overdose of buprenorphine [see Warnings and Precautions (5.2)].

Neonatal Opioid Withdrawal Syndrome

Prolonged use of Butrans during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [see Warnings and Precautions (5.3)].

Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants

Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death [see Warnings and Precautions (5.4), Drug Interactions (7)].

  • Reserve concomitant prescribing of BUTRANS and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate.
  • Limit dosages and durations to the minimum required.
  • Follow patients for signs and symptoms of respiratory depression and sedation.
INDICATIONS AND USAGE

Butrans® (buprenorphine) transdermal system CIII is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

Limitations of Use
  • Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risk of overdose and death with extended-release opioid formulations, reserve Butrans for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.

  • Butrans is not indicated as an as-needed (prn) analgesic.

CONTRAINDICATIONS
  • Butrans is contraindicated in patients with significant respiratory depression; acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment; known or suspected gastrointestinal obstruction, including paralytic ileus; hypersensitivity (e.g., anaphylaxis) to buprenorphine.

WARNINGS AND PRECAUTIONS Addiction, Abuse, and Misuse
  • Butrans contains buprenorphine, a Schedule III controlled substance. Butrans exposes users to the risks of opioid addiction, abuse, and misuse. Because extended-release products such as Butrans deliver the opioid over an extended period of time, there is a greater risk for overdose and death, due to the larger amount of buprenorphine present.

  • Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed Butrans. Addiction can occur at recommended doses and if the drug is misused or abused.

  • Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing Butrans, and monitor all patients receiving Butrans for the development of these behaviors and conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as Butrans, but use in such patients necessitates intensive counseling about the risks and proper use of Butrans, along with intensive monitoring for signs of addiction, abuse, or misuse.

  • Abuse or misuse of Butrans by placing it in the mouth, chewing it, swallowing it, or using it in ways other than indicated may cause choking, overdose and death.

  • Opioids are sought by drug abusers and people with addiction disorders and are subject to criminal diversion. Consider these risks when prescribing or dispensing Butrans. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on the proper disposal of unused drug.

Life‐Threatening Respiratory Depression
  • Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended, and if not immediately recognized and treated, may lead to respiratory arrest and death.

  • While serious, life‐threatening, or fatal respiratory depression can occur at any time during the use of Butrans, the risk is greatest during the initiation of therapy or following a dosage increase. Closely monitor patients for respiratory depression, especially within the first 24–72 hours of initiating therapy with and following dosage increases of Butrans.

  • To reduce the risk of respiratory depression, proper dosing and titration of Butrans are essential. Overestimating the Butrans dosage when converting patients from another opioid product can result in fatal overdose with the first dose.

  • Accidental exposure to Butrans, especially in children, can result in respiratory depression and death due to an overdose of buprenorphine.

Neonatal Opioid Withdrawal Syndrome
  • Prolonged use of Butrans during pregnancy can result in withdrawal in the neonate. Neonatal opioid withdrawal syndrome, unlike opioid withdrawal syndrome in adults, may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. Observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly. Advise pregnant women using opioids for a prolonged period of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.

Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants
  • Profound sedation, respiratory depression, coma and death may result from the concomitant use of Butrans with benzodiazepines or other CNS depressants (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol). Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate.

  • If the decision is made to prescribe a benzodiazepine or other CNS depressant concomitantly with an opioid analgesic, prescribe the lowest effective dosages and minimum durations of concomitant use. In patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response. If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant, prescribe a lower initial dose of the opioid analgesic, and titrate based on clinical response. Follow patients closely for signs and symptoms of respiratory depression and sedation.

  • Advise both patients and caregivers about the risks of respiratory depression and sedation when Butrans is used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise patients not to drive or operate heavy machinery until the effects of concomitant use of the benzodiazepine or other CNS depressant have been determined. Screen patients for risk of substance use disorders, including opioid abuse and misuse, and warn them of the risk for overdose and death associated with the use of additional CNS depressants including alcohol and illicit drugs.

Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients
  • The use of Butrans in patients with acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment is contraindicated.

  • Butrans-treated patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression are at increased risk of decreased respiratory drive including apnea, even at recommended dosages of Butrans.

  • Life-threatening respiratory depression is more likely to occur in elderly, cachectic, or debilitated patients because they may have altered pharmacokinetics or altered clearance compared to younger, healthier patients.

  • Monitor such patients closely, particularly when initiating and titrating Butrans and when Butrans is given concomitantly with other drugs that depress respiration. Alternatively, consider the use of non-opioid analgesics in these patients.

Adrenal Insufficiency
  • Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers.

QTc Prolongation
  • A positive‐controlled study of the effects of Butrans on the QTc interval in healthy subjects demonstrated no clinically meaningful effect at a Butrans dose of 10 mcg/hour; however, a Butrans dose of 40 mcg/hour (given as two Butrans 20 mcg/hour Transdermal Systems) was observed to prolong the QTc interval.

  • Consider these observations in clinical decisions when prescribing Butrans to patients with hypokalemia or clinically unstable cardiac disease, including: unstable atrial fibrillation, symptomatic bradycardia, unstable congestive heart failure, or active myocardial ischemia. Avoid the use of Butrans in patients with a history of Long QT Syndrome or an immediate family member with this condition, or those taking Class IA antiarrhythmic medications (e.g., quinidine, procainamide, disopyramide) or Class III antiarrhythmic medications (e.g., sotalol, amiodarone, dofetilide), or other medications that prolong the QTc interval.

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

Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness
  • In patients who may be susceptible to the intracranial effects of CO2 retention (e.g., those with evidence of increased intracranial pressure or brain tumors), Butrans may reduce respiratory drive, and the resultant CO2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with Butrans.

  • Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of Butrans in patients with impaired consciousness or coma.

Hepatotoxicity
  • Cases of cytolytic hepatitis and hepatitis with jaundice have been observed in individuals receiving sublingual buprenorphine for the treatment of opioid dependence, both in clinical trials and in post‐marketing adverse event reports. For patients at increased risk of hepatotoxicity, obtain baseline liver enzyme levels and monitor periodically and during treatment with Butrans.

Application Site Skin Reactions
  • In rare cases, severe application site skin reactions with signs of marked inflammation including “burn,” “discharge,” and “vesicles” have occurred. Time of onset varies, ranging from days to months following the initiation of Butrans treatment. Instruct patients to promptly report the development of severe application site reactions and discontinue therapy.

Anaphylactic/Allergic Reactions
  • Cases of acute and chronic hypersensitivity to buprenorphine have been reported both in clinical trials and in the post‐marketing experience. The most common signs and symptoms include rashes, hives, and pruritus. Cases of bronchospasm, angioneurotic edema, and anaphylactic shock have been reported. A history of hypersensitivity to buprenorphine is a contraindication to the use of Butrans.

Risks of Use with Application of External Heat
  • Advise patients and their caregivers to avoid exposing the Butrans application site and surrounding area to direct external heat sources, such as heating pads or electric blankets, heat or tanning lamps, saunas, hot tubs, and heated water beds while wearing the system because an increase in absorption of buprenorphine may occur. Advise patients against exposure of the Butrans application site and surrounding area to hot water or prolonged exposure to direct sunlight. There is a potential for temperature-dependent increases in buprenorphine released from the system resulting in possible overdose and death.

Risks of Use in Patients with Fever
  • Monitor patients wearing Butrans systems who develop fever or increased core body temperature due to strenuous exertion for opioid side effects and adjust the Butrans dose if signs of respiratory or central nervous system depression occur.

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

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

Risks of Driving and Operating Machinery
  • Butrans may impair the mental and physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of Butrans and know how they will react to the medication.

Use in Addiction Treatment
  • Butrans has not been studied and is not approved for use in the management of addictive disorders.

ADVERSE REACTIONS
  • The most common adverse reactions (≥5%) reported by patients treated with Butrans in clinical trials were nausea, headache, application site pruritus, dizziness, constipation, somnolence, vomiting, application site erythema, dry mouth, and application site rash.

  • Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers.

QTc Prolongation
  • A positive‐controlled study of the effects of Butrans on the QTc interval in healthy subjects demonstrated no clinically meaningful effect at a Butrans dose of 10 mcg/hour; however, a Butrans dose of 40 mcg/hour (given as two Butrans 20 mcg/hour Transdermal Systems) was observed to prolong the QTc interval.

  • Consider these observations in clinical decisions when prescribing Butrans to patients with hypokalemia or clinically unstable cardiac disease, including: unstable atrial fibrillation, symptomatic bradycardia, unstable congestive heart failure, or active myocardial ischemia. Avoid the use of Butrans in patients with a history of Long QT Syndrome or an immediate family member with this condition, or those taking Class IA antiarrhythmic medications (e.g., quinidine, procainamide, disopyramide) or Class III antiarrhythmic medications (e.g., sotalol, amiodarone, dofetilide), or other medications that prolong the QTc interval.

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

Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness
  • In patients who may be susceptible to the intracranial effects of CO2 retention (e.g., those with evidence of increased intracranial pressure or brain tumors), Butrans may reduce respiratory drive, and the resultant CO2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with Butrans.

  • Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of Butrans in patients with impaired consciousness or coma.

Hepatotoxicity
  • Cases of cytolytic hepatitis and hepatitis with jaundice have been observed in individuals receiving sublingual buprenorphine for the treatment of opioid dependence, both in clinical trials and in post‐marketing adverse event reports. For patients at increased risk of hepatotoxicity, obtain baseline liver enzyme levels and monitor periodically and during treatment with Butrans.

Application Site Skin Reactions
  • In rare cases, severe application site skin reactions with signs of marked inflammation including “burn,” “discharge,” and “vesicles” have occurred. Time of onset varies, ranging from days to months following the initiation of Butrans treatment. Instruct patients to promptly report the development of severe application site reactions and discontinue therapy.

Anaphylactic/Allergic Reactions
  • Cases of acute and chronic hypersensitivity to buprenorphine have been reported both in clinical trials and in the post‐marketing experience. The most common signs and symptoms include rashes, hives, and pruritus. Cases of bronchospasm, angioneurotic edema, and anaphylactic shock have been reported. A history of hypersensitivity to buprenorphine is a contraindication to the use of Butrans.

Risks of Use with Application of External Heat
  • Advise patients and their caregivers to avoid exposing the Butrans application site and surrounding area to direct external heat sources, such as heating pads or electric blankets, heat or tanning lamps, saunas, hot tubs, and heated water beds while wearing the system because an increase in absorption of buprenorphine may occur. Advise patients against exposure of the Butrans application site and surrounding area to hot water or prolonged exposure to direct sunlight. There is a potential for temperature-dependent increases in buprenorphine released from the system resulting in possible overdose and death.

Risks of Use in Patients with Fever
  • Monitor patients wearing Butrans systems who develop fever or increased core body temperature due to strenuous exertion for opioid side effects and adjust the Butrans dose if signs of respiratory or central nervous system depression occur.

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

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

Risks of Driving and Operating Machinery
  • Butrans may impair the mental and physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of Butrans and know how they will react to the medication.

Use in Addiction Treatment
  • Butrans has not been studied and is not approved for use in the management of addictive disorders.

ADVERSE REACTIONS
  • The most common adverse reactions (≥5%) reported by patients treated with Butrans in clinical trials were nausea, headache, application site pruritus, dizziness, constipation, somnolence, vomiting, application site erythema, dry mouth, and application site rash.

WARNING: ADDICTION, ABUSE and MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL EXPOSURE; NEONATAL OPIOID WITHDRAWAL SYNDROME; and RISKS FROM CONCOMITANT USE WITH BENZODIAZEPINES OR OTHER CNS DEPRESSANTS

Addiction, Abuse, and Misuse

Butrans exposes patients and other users to the risks of opioid addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient’s risk prior to prescribing Butrans, and monitor all patients regularly for the development of these behaviors and conditions [see Warnings and Precautions (5.1) and Overdosage (10)].

Life-Threatening Respiratory Depression

Serious, life-threatening, or fatal respiratory depression may occur with use of Butrans. Monitor for respiratory depression, especially during initiation of Butrans or following a dose increase. Misuse or abuse of Butrans by chewing, swallowing, snorting or injecting buprenorphine extracted from the transdermal system will result in the uncontrolled delivery of buprenorphine and pose a significant risk of overdose and death [see Warnings and Precautions (5.2)].

Accidental Exposure

Accidental exposure to even one dose of Butrans, especially in children, can result in a fatal overdose of buprenorphine [see Warnings and Precautions (5.2)].

Neonatal Opioid Withdrawal Syndrome

Prolonged use of Butrans during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available [see Warnings and Precautions (5.3)].

Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants

Concomitant use of opioids with benzodiazepines or other central nervous system (CNS) depressants, including alcohol, may result in profound sedation, respiratory depression, coma, and death [see Warnings and Precautions (5.4), Drug Interactions (7)].

  • Reserve concomitant prescribing of BUTRANS and benzodiazepines or other CNS depressants for use in patients for whom alternative treatment options are inadequate.
  • Limit dosages and durations to the minimum required.
  • Follow patients for signs and symptoms of respiratory depression and sedation.
INDICATIONS AND USAGE

Butrans® (buprenorphine) transdermal system CIII is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.

Limitations of Use
  • Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risk of overdose and death with extended-release opioid formulations, reserve Butrans for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.

  • Butrans is not indicated as an as-needed (prn) analgesic.

CONTRAINDICATIONS
  • Butrans is contraindicated in patients with significant respiratory depression; acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment; known or suspected gastrointestinal obstruction, including paralytic ileus; hypersensitivity (e.g., anaphylaxis) to buprenorphine.

WARNINGS AND PRECAUTIONS Addiction, Abuse, and Misuse
  • Butrans contains buprenorphine, a Schedule III controlled substance. Butrans exposes users to the risks of opioid addiction, abuse, and misuse. Because extended-release products such as Butrans deliver the opioid over an extended period of time, there is a greater risk for overdose and death, due to the larger amount of buprenorphine present.

  • Although the risk of addiction in any individual is unknown, it can occur in patients appropriately prescribed Butrans. Addiction can occur at recommended doses and if the drug is misused or abused.

  • Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing Butrans, and monitor all patients receiving Butrans for the development of these behaviors and conditions. Risks are increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not, however, prevent the proper management of pain in any given patient. Patients at increased risk may be prescribed opioids such as Butrans, but use in such patients necessitates intensive counseling about the risks and proper use of Butrans, along with intensive monitoring for signs of addiction, abuse, or misuse.

  • Abuse or misuse of Butrans by placing it in the mouth, chewing it, swallowing it, or using it in ways other than indicated may cause choking, overdose and death.

  • Opioids are sought by drug abusers and people with addiction disorders and are subject to criminal diversion. Consider these risks when prescribing or dispensing Butrans. Strategies to reduce these risks include prescribing the drug in the smallest appropriate quantity and advising the patient on the proper disposal of unused drug.

Life‐Threatening Respiratory Depression
  • Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids, even when used as recommended, and if not immediately recognized and treated, may lead to respiratory arrest and death.

  • While serious, life‐threatening, or fatal respiratory depression can occur at any time during the use of Butrans, the risk is greatest during the initiation of therapy or following a dosage increase. Closely monitor patients for respiratory depression, especially within the first 24–72 hours of initiating therapy with and following dosage increases of Butrans.

  • To reduce the risk of respiratory depression, proper dosing and titration of Butrans are essential. Overestimating the Butrans dosage when converting patients from another opioid product can result in fatal overdose with the first dose.

  • Accidental exposure to Butrans, especially in children, can result in respiratory depression and death due to an overdose of buprenorphine.

Neonatal Opioid Withdrawal Syndrome
  • Prolonged use of Butrans during pregnancy can result in withdrawal in the neonate. Neonatal opioid withdrawal syndrome, unlike opioid withdrawal syndrome in adults, may be life-threatening if not recognized and treated, and requires management according to protocols developed by neonatology experts. Observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly. Advise pregnant women using opioids for a prolonged period of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.

Risks from Concomitant Use with Benzodiazepines or Other CNS Depressants
  • Profound sedation, respiratory depression, coma and death may result from the concomitant use of Butrans with benzodiazepines or other CNS depressants (e.g., non-benzodiazepine sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol). Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate.

  • If the decision is made to prescribe a benzodiazepine or other CNS depressant concomitantly with an opioid analgesic, prescribe the lowest effective dosages and minimum durations of concomitant use. In patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response. If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant, prescribe a lower initial dose of the opioid analgesic, and titrate based on clinical response. Follow patients closely for signs and symptoms of respiratory depression and sedation.

  • Advise both patients and caregivers about the risks of respiratory depression and sedation when Butrans is used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise patients not to drive or operate heavy machinery until the effects of concomitant use of the benzodiazepine or other CNS depressant have been determined. Screen patients for risk of substance use disorders, including opioid abuse and misuse, and warn them of the risk for overdose and death associated with the use of additional CNS depressants including alcohol and illicit drugs.

Life-Threatening Respiratory Depression in Patients with Chronic Pulmonary Disease or in Elderly, Cachectic, or Debilitated Patients
  • The use of Butrans in patients with acute or severe bronchial asthma in an unmonitored setting or in the absence of resuscitative equipment is contraindicated.

  • Butrans-treated patients with significant chronic obstructive pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve, hypoxia, hypercapnia, or pre-existing respiratory depression are at increased risk of decreased respiratory drive including apnea, even at recommended dosages of Butrans.

  • Life-threatening respiratory depression is more likely to occur in elderly, cachectic, or debilitated patients because they may have altered pharmacokinetics or altered clearance compared to younger, healthier patients.

  • Monitor such patients closely, particularly when initiating and titrating Butrans and when Butrans is given concomitantly with other drugs that depress respiration. Alternatively, consider the use of non-opioid analgesics in these patients.

Adrenal Insufficiency
  • Cases of adrenal insufficiency have been reported with opioid use, more often following greater than one month of use. If adrenal insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers.

QTc Prolongation
  • A positive‐controlled study of the effects of Butrans on the QTc interval in healthy subjects demonstrated no clinically meaningful effect at a Butrans dose of 10 mcg/hour; however, a Butrans dose of 40 mcg/hour (given as two Butrans 20 mcg/hour Transdermal Systems) was observed to prolong the QTc interval.

  • Consider these observations in clinical decisions when prescribing Butrans to patients with hypokalemia or clinically unstable cardiac disease, including: unstable atrial fibrillation, symptomatic bradycardia, unstable congestive heart failure, or active myocardial ischemia. Avoid the use of Butrans in patients with a history of Long QT Syndrome or an immediate family member with this condition, or those taking Class IA antiarrhythmic medications (e.g., quinidine, procainamide, disopyramide) or Class III antiarrhythmic medications (e.g., sotalol, amiodarone, dofetilide), or other medications that prolong the QTc interval.

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

Risks of Use in Patients with Increased Intracranial Pressure, Brain Tumors, Head Injury, or Impaired Consciousness
  • In patients who may be susceptible to the intracranial effects of CO2 retention (e.g., those with evidence of increased intracranial pressure or brain tumors), Butrans may reduce respiratory drive, and the resultant CO2 retention can further increase intracranial pressure. Monitor such patients for signs of sedation and respiratory depression, particularly when initiating therapy with Butrans.

  • Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of Butrans in patients with impaired consciousness or coma.

Hepatotoxicity
  • Cases of cytolytic hepatitis and hepatitis with jaundice have been observed in individuals receiving sublingual buprenorphine for the treatment of opioid dependence, both in clinical trials and in post‐marketing adverse event reports. For patients at increased risk of hepatotoxicity, obtain baseline liver enzyme levels and monitor periodically and during treatment with Butrans.

Application Site Skin Reactions
  • In rare cases, severe application site skin reactions with signs of marked inflammation including “burn,” “discharge,” and “vesicles” have occurred. Time of onset varies, ranging from days to months following the initiation of Butrans treatment. Instruct patients to promptly report the development of severe application site reactions and discontinue therapy.

Anaphylactic/Allergic Reactions
  • Cases of acute and chronic hypersensitivity to buprenorphine have been reported both in clinical trials and in the post‐marketing experience. The most common signs and symptoms include rashes, hives, and pruritus. Cases of bronchospasm, angioneurotic edema, and anaphylactic shock have been reported. A history of hypersensitivity to buprenorphine is a contraindication to the use of Butrans.

Risks of Use with Application of External Heat
  • Advise patients and their caregivers to avoid exposing the Butrans application site and surrounding area to direct external heat sources, such as heating pads or electric blankets, heat or tanning lamps, saunas, hot tubs, and heated water beds while wearing the system because an increase in absorption of buprenorphine may occur. Advise patients against exposure of the Butrans application site and surrounding area to hot water or prolonged exposure to direct sunlight. There is a potential for temperature-dependent increases in buprenorphine released from the system resulting in possible overdose and death.

Risks of Use in Patients with Fever
  • Monitor patients wearing Butrans systems who develop fever or increased core body temperature due to strenuous exertion for opioid side effects and adjust the Butrans dose if signs of respiratory or central nervous system depression occur.

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

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

Risks of Driving and Operating Machinery
  • Butrans may impair the mental and physical abilities needed to perform potentially hazardous activities such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery unless they are tolerant to the effects of Butrans and know how they will react to the medication.

Use in Addiction Treatment
  • Butrans has not been studied and is not approved for use in the management of addictive disorders.

ADVERSE REACTIONS
  • The most common adverse reactions (≥5%) reported by patients treated with Butrans in clinical trials were nausea, headache, application site pruritus, dizziness, constipation, somnolence, vomiting, application site erythema, dry mouth, and application site rash.
