Dosing Considerations

For prescriber qualifications, see prescribing information

Also given in combination with naloxone

Induction with SL tablets

  • Patients dependent on heroin or other short-acting opioids
    • At initiation, administer first dose of buprenorphine SL tablets only when signs/symptoms of moderate opioid withdrawal appear, and ≥4 hr after patient last used an opioid
    • Titrate to clinical effectiveness achieved as rapidly as possible; dosing on the initial day of treatment may be given in 2-4 mg increments if preferred
  • Patients dependent on methadone or other long-acting opioids
    • Administer first dose of buprenorphine sublingual tablets should when clear signs/symptoms of moderate opioid withdrawal appear, and generally ≥24 hr after the patient last used a long-acting opioids

Access to naloxone for opioid overdose

  • Assess need for naloxone upon initiating and renewing treatment
  • Consider prescribing naloxone
    • Based on patient’s risk factors for overdose (eg, concomitant use of CNS depressants, a history of opioid use disorder, prior opioid overdose); presence of risk factors should not prevent proper pain management
    • Household members (including children) or other close contacts at risk for accidental ingestion or overdose
  • Consult patients and caregivers on the following:
    • Availability of naloxone for emergency treatment of opioid overdose
    • Ways differ on how to obtain naloxone as permitted by individual state dispensing and prescribing requirements or guidelines (eg, by prescription, directly from a pharmacist, as part of a community-based program)

            • To ensure that benefits of opioid analgesics outweigh risks of addiction, abuse, and misuse, the Food and Drug Administration (FDA) has required a REMS for these products; under requirements of the REMS, drug companies with approved opioid analgesic products must make REMS-compliant education programs available to healthcare providers
            • Healthcare providers are strongly encouraged to:
              • Complete a REMS-compliant education program
              • Counsel patients and/or their caregivers, with every prescription, on safe use, serious risks, storage, and disposal of these products
              • Emphasize to patients and their caregivers the importance of reading the Medication Guide every time it is provided by their pharmacist
              • Consider other tools to improve patient, household, and community safety
              • To obtain further information on opioid analgesic REMS and for a list of accredited REMS CME/CE, call 1-800-503-0784, or log on to www.opioidanalgesicrems.com; the FDA Blueprint can be found at www.fda.gov/OpioidAnalgesicREMSBlueprint

            Addiction, abuse, and misuse

            • Risk of opioid addiction, abuse, and misuse, which can lead to overdose and death
            • Assess each patient’s risk prior to prescribing and monitor all patients regularly for the development of these behaviors or conditions

            Life-threatening respiratory depression

            • Serious, life-threatening, or fatal respiratory depression may occur
            • Monitor for respiratory depression, especially during initiation or following a dose increase

            Accidental exposure

            • Accidental exposure of even 1 dose, especially by children, can result in a fatal overdose

            Neonatal opioid withdrawal syndrome

            • Prolonged use 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
            • Syndrome presents as irritability, hyperactivity and abnormal sleep pattern, high-pitched cry, tremor, vomiting, diarrhea, and failure to gain weight
            • Onset, duration, and severity of neonatal opioid withdrawal syndrome vary based on the specific opioid used, duration of use, timing and amount of last maternal use, and rate of elimination of the drug by the newborn
            • 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

            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; reserve concomitant use in patients for whom alternative treatment options are inadequate; limit dosages and durations to minimum required; and monitor for signs and symptoms of respiratory depression and sedation

            Contraindications

            Hypersensitivity

            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

            Cautions

            Partial agonist at the mu opioid receptor and a schedule III controlled opioid exposes users to the risks of addiction, abuse, and misuse; there is a greater risk for overdose and death with extended-release opioids owing to the larger amount of active opioid present (see Black Box Warnings)

            Serious, life-threatening, or fatal respiratory depression reported; may occur more frequently in elderly or debilitated patients, or in conditions associated with hypoxia or hypercapnia (even moderate therapeutic doses) (see Black Box Warnings)

            Neonatal opioid withdrawal syndrome reported with long-term use during pregnancy (see Black Box Warnings)

            Do not abruptly discontinue buprenorphine in a patient physically dependent on opioids; when discontinuing therapy, in a physically dependent patient, gradually taper the dosage; rapid tapering in a patient physically dependent on opioids may lead to a withdrawal syndrome and return of pain

            Accidental exposure reported, including fatalities (see Black Box Warnings)

            May impair mental or physical abilities needed to perform potentially hazardous activities (eg, driving a car, operating machinery)

            Risk of apnea in patients with chronic pulmonary disease; closely monitor these patients, when initiating and titrating therapy; alternatively, consider the use of alternative non-opioid analgesics in these patients (see Black Box Warnings and Contraindications)

            QTc prolongation observed in healthy individuals at 40 mcg/hr; avoid in patients with history of long QT syndrome or coadministration with class IA (eg, quinidine, procainamide, disopyramide) or class III (eg, sotalol, amiodarone, dofetilide) antiarrhythmics

            Respiratory depressant effects of opioids may include carbon dioxide retention and lead to elevated CSF pressure

            Opioids can cause sleep-related breathing disorders including central sleep apnea (CSA) and sleep-related hypoxemia; opioid use increases risk of CSA in a dose-dependent fashion; in patients who present with CSA, consider decreasing opioid dosage using best practices for opioid taper

            Can cause severe hypotension; caution with depleted blood volume or coadministration of drugs that that affect vasomotor tone (eg, phenothiazines), vasodilators, or antihypertensives

            Hypothyroidism, myxedema, adrenocortical insufficiency, alcohol intoxication, alcohol withdrawal syndrome, coma, geriatric or debilitated patients, delirium tremens, toxic psychoses, kyphoscoliosis, prostatic hypertrophy, urethral stricture, central nervous system (CNS) depression, biliary tract dysfunction, head injury, intracranial lesions, intracranial hypertension or conditions in which intracranial pressure may be increased

            Cases of cytolytic hepatitis and hepatitis with jaundice observed in individuals receiving buprenorphine SL for opioid dependence treatment; increased risk for overdose with moderate or severe hepatic impairment (see Dosage Modifications)

            Anaphylactic reactions reported

            May cause sphincter of Oddi spasm and aggravate abdominal conditions, including ileus (see Contraindications)

            Similar to other opioids, may aggravate seizure disorders by lowering seizure threshold

            Special risk groups may experience increased adverse reactions; caution with alcoholism, delirium tremens, adrenocortical insufficiency, CNS depression, debilitation, kyphoscoliosis associated with respiratory compromise, myxedema or hypothyroidism, prostatic hypertrophy or urethral stricture, severe impairment of hepatic, pulmonary or renal function, and toxic psychosis

            Prescribers should discuss with patients importance and benefits of management of opioid addiction throughout pregnancy

            Cases of adrenal insufficiency reported with opioid use, more often following greater than one month of use; symptoms may include nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure; if adrenal insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids; wean patient off of opioid to allow adrenal function to recover and continue corticosteroid treatment until adrenal function recovers; other opioids may be tried as some cases reported use of a different opioid without recurrence of adrenal insufficiency

            Consider discontinuing therapy 24-36 hr prior anticipated need for surgical anesthesia to undergo elective surgery; may administer short-acting opioids during and/or after surgery; in patients unable to abruptly discontinue therapy may add full opioid to buprenorphine to maintain proper anesthesia; increased doses may be required to overcome buprenorphine receptor blockade; continuously monitor if opioid therapy required as part of anesthesia in an anesthesia care setting

            Abrupt discontinuation following prolonged therapy may lead to withdrawal symptoms; not recommended; taper gradually

            Use caution in patients who are morbidly obese

            Avoid use in patients with impaired consciousness or coma; patients are susceptible to intracranial effects of CO2 retention

            Use caution in patients with a history of ileus or bowel obstruction; contraindicated in patients with known or suspected GI obstruction including paralytic ileus

            Chronic use of opioids may cause reduced fertility in females and males of reproductive potential; unknown whether effects on fertility are reversible (see Pregnancy)

            Patient access to naloxone for emergency treatment of opioid overdose

            • Assess potential need for naloxone; consider prescribing for emergency treatment of opioid overdose
            • Consult on availability and ways to obtain naloxone as permitted by individual state naloxone dispensing and prescribing requirements or guidelines
            • Educate patients regarding the signs and symptoms of respiratory depression and to call 911 or seek immediate emergency medical help in the event of a known or suspected overdose

            Increased risk of dental problems

            • On January 12, 2022, FDA warned of potential dental problems associated with transmucosal buprenorphine-containing products (eg, buccal, sublingual)
            • Dental problems (ie, tooth decay, cavities, oral infections, loss of teeth), can be serious and have been reported even in patients with no history of dental issues
            • Despite these risks, buprenorphine is an important treatment option for opioid use disorder and pain, and the benefits of these medicines clearly outweigh the risks
            • Review patient’s health before initiating with transmucosal buprenorphine
            • Counsel patients regarding potential for dental problems and importance of taking extra steps after the medicine has completely dissolved, including gently rinsing teeth and gums with water and then swallow; advise to wait at least 1 hour before brushing their teeth
            • Dentists treating patients taking transmucosal buprenorphine should perform a baseline dental evaluation and caries risk assessment, establish a dental caries preventive plan, and encourage regular dental checkups

            Drug interactions overview

            • Concomitant use of buprenorphine and benzodiazepines, a muscle relaxant, or other CNS depressants increases risk of adverse reactions including overdose and death; 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; if concomitant use with benzodiazepine ior muscle relaxant s warranted, consider prescribing naloxone for the emergency treatment of opioid overdose (See Black Box Warnings)
            • Opioids may reduce efficacy of diuretics by inducing release of antidiuretic hormone
            • Anticholinergic drugs may increase risk of urinary retention and/or severe constipation, which may lead to paralytic ileus; monitor for signs of urinary retention or reduced gastric motility when buprenorphine is concomitantly used with anticholinergics
            • Serotonergic drugs
              • Opioids may enhance serotonergic effect of drugs (eg, selective serotonin reuptake inhibitors, monoamine oxidase inhibitors) that affect the serotonergic neurotransmitter system; which increases the risk of serotonin syndrome; if concomitant use is warranted, monitor; discontinue if serotonin syndrome is suspected
              • Use of MAOIs with buprenorphine is not recommended during or within 14 days of discontinuing treatment
            • CYP3A4 inhibitors
              • Concomitant use of buprenorphine and CYP3A4 inhibitor may increase the plasma concentration of buprenorphine, resulting increased or prolonged opioid effects; specifically when adding a CYP3A4 inhibitor after achieving a stable buprenorphine dose
            • CYP3A4 inducers
              • Concomitant use of buprenorphine and CYP3A4 inducers may decrease plasma concentration of buprenorphine, potentially resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to buprenorphine

            Pregnancy & Lactation

            Pregnancy

            Data in pregnancy are limited; however, these data do not indicate an increased risk of major malformations specifically due to buprenorphine exposure; observational studies reported on congenital malformations among exposed pregnancies, but were also not designed appropriately to assess risk of congenital malformations specifically due to drug exposure

            Dosage adjustments of buprenorphine may be required during pregnancy, even if patient was maintained on stable dose prior to pregnancy; withdrawal signs and symptoms should be monitored closely and the dose adjusted as necessary

            Fetal/neonatal adverse reactions

            • Neonatal opioid withdrawal syndrome may occur in newborn infants of mothers who are receiving treatment

            Lactation

            Data on two studies in 13 lactating women receiving therapy where the drug and it metabolite were present in low levels in human milk did not show adverse reactions in breastfed infants; developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed child from drug or from underlying maternal condition

            Advise breastfeeding women taking buprenorphine products to monitor infant for increased drowsiness and breathing difficulties

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

            BUPRENORPHINE - TRANSDERMAL

            (BUE-pre-NOR-feen)

            COMMON BRAND NAME(S): Butrans

            WARNING: Buprenorphine has a risk for abuse and addiction, which can lead to overdose and death. Buprenorphine may also cause severe, possibly fatal, breathing problems. To lower your risk, your doctor should have you use the smallest dose of buprenorphine that works, and use it for the shortest possible time. See also How to Use section for more information about addiction.Ask your doctor or pharmacist if you should have naloxone available to treat opioid overdose. Teach your family or household members about the signs of an opioid overdose and how to treat it.The risk for severe breathing problems is higher when you start this medication and after a dose increase, or if you use the wrong dose/strength or misuse the medication (such as chewing or swallowing the patch). Using this medication with alcohol or other drugs that can cause drowsiness or breathing problems may cause very serious side effects, including death. Be sure you know how to use buprenorphine and what other drugs you should avoid taking with it. See also Drug Interactions section. Get medical help right away if any of these very serious side effects occur: slow/shallow breathing, unusual lightheadedness, severe drowsiness/dizziness, difficulty waking up.Keep this medicine in a safe place to prevent theft, misuse, or abuse. If someone accidentally swallows or uses this drug, get medical help right away because fatal breathing problems may occur.Before using this medication, women of childbearing age should talk with their doctor(s) about the risks and benefits. Tell your doctor if you are pregnant or if you plan to become pregnant. During pregnancy, this medication should be used only when clearly needed. It may slightly increase the risk of birth defects if used during the first two months of pregnancy. Also, using it for a long time or in high doses near the expected delivery date may harm the unborn baby. To lessen the risk, use the smallest effective dose for the shortest possible time. Babies born to mothers who use this drug for a long time may develop severe (possibly fatal) withdrawal symptoms. Tell the doctor right away if you notice any symptoms in your newborn baby such as crying that doesn't stop, slow/shallow breathing, irritability, shaking, vomiting, diarrhea, poor feeding, or difficulty gaining weight.

            USES: This medication is used to help relieve severe ongoing pain (such as due to arthritis, chronic back pain). Buprenorphine belongs to a class of drugs known as opioid analgesics. It works in the brain to change how your body feels and responds to pain.The higher strengths of this drug (7.5, 10, 15, or 20 micrograms per hour patches) should be used only if you have been regularly taking moderate amounts of opioid pain medication. These strengths may cause overdose (even death) if used by a person who has not been regularly taking opioids.Do not use this medication to relieve pain that is mild or that will go away in a few days. This medication is not for occasional ("as needed") use.

            HOW TO USE: See also Warning section.Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. Learn how to properly use, store, and discard the patches. If you have any questions, ask your doctor or pharmacist.Use this medication on a regular schedule as directed by your doctor, not as needed for sudden (breakthrough) pain. If you are already using an opioid medication, ask your doctor or pharmacist if you should stop or change how you use your other opioid medication. It may take 24 hours or longer before you have pain relief from buprenorphine patches. Other pain relievers (such as acetaminophen, ibuprofen) may also be prescribed. Ask your doctor or pharmacist about using buprenorphine safely with other drugs.Apply this medication to the skin as directed by your doctor. Do not apply on burns, cuts, irritated skin, or skin that has been exposed to radiation (x-ray treatment). Select a dry, non-hairy area on a flat part of your body, such as the upper chest, sides of the chest, upper back, or upper outer arms. In people unable to think clearly (such as due to dementia), apply the patch on the upper back to lessen the chance it might be removed or placed in the mouth. If there is hair on the skin, use scissors to clip the hair as close as possible to the skin. Do not shave hair since this might cause skin irritation. If needed, use water to clean the area. Do not use soap, oils, lotions, or alcohol on the application site. Dry the skin well before applying the patch.The patch is usually changed every 7 days. To avoid irritation, apply to a different area each time and do not apply to the same site within 3 weeks. Be sure to remove the old patch before applying a new patch. The used patch should be folded in half with the sticky sides together and properly discarded. If your manufacturer has supplied a patch disposal unit, follow directions for its use.Do not use the patch if it appears to be broken, cut, or damaged. Remove from the sealed pouch, peel off the protective liner, and apply right away to the skin. Press firmly in place with the palm of the hand for about 15 to 30 seconds, making sure the contact is complete (especially around the edges). If your prescribed dose is for more than one patch, apply them right next to each other but make sure the edges of the patches do not touch or overlap. After applying the patch, wash your hands with water only.You may bathe, shower, or swim while wearing the patch. If you have problems with the patch not sticking at the application site, you may tape the edges in place with certain kinds of first aid tape. Ask your doctor or pharmacist about which type of tape should be used. If this problem lasts, ask your doctor for advice. If the patch falls off before 7 days, a new patch may be applied to a different skin site. Be sure to let your doctor know if this happens.If you accidentally touch the sticky layer to your skin or handle a cut or damaged patch, wash the area well with clear water. If the patch comes off and accidentally sticks to the skin of another person, immediately remove the patch, wash the area with water, and get medical help for them right away. Do not use soap, alcohol, or other products to wash the area.The dosage is based on your medical condition and response to treatment. Do not apply more patches than directed, change them more often, or use them for a longer time than prescribed.
