What Is Buprenorphine Used For?
1 INDICATIONS AND USAGE Buprenorphine sublingual tablet is indicated for the treatment of opioid dependence and is preferred for induction. Buprenorphine sublingual tablet should be used as part of a complete treatment plan to include counseling and psychosocial support. Buprenorphine sublingual tablet, contains buprenorphine, a partial opioid agonist, and is indicated for the treatment of opioid dependence and is preferred for induction. (1) Buprenorphine sublingual tablet should be used as part of a complete treatment plan that includes counseling and psychosocial support. (1)
Dosage and Administration
2 DOSAGE AND ADMINISTRATION Administer buprenorphine sublingual tablet sublingually as a single daily dose. (2.1) Strongly consider prescribing naloxone at the time buprenorphine sublingual tablet is initiated or renewed because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose. (2.2) To avoid precipitating withdrawal, induction with buprenorphine sublingual tablet should be undertaken when objective and clear signs of withdrawal are evident. (2.3) Buprenorphine and naloxone sublingual film or buprenorphine and naloxone sublingual tablet is generally initiated after two days of buprenorphine sublingual tablet titration. (2.4) Administer buprenorphine sublingual tablets as directed in the Full Prescribing Information. (2.3, 2.4, 2.5) Buprenorphine sublingual tablet must be administered whole. Do not cut, chew, or swallow buprenorphine sublingual tablets. (2.5) When discontinuing treatment, gradually taper to avoid signs and symptoms of withdrawal. (2.9) 2.1 Important Dosage and Administration Instructions Buprenorphine sublingual tablet is administered sublingually as a single daily dose. Buprenorphine sublingual tablet does not contain naloxone and is preferred for use only during induction. Following induction, buprenorphine and naloxone sublingual film or buprenorphine and naloxone sublingual tablet is preferred due to the presence of naloxone when clinical use includes unsupervised administration. The use of buprenorphine sublingual tablet for unsupervised administration should be limited to those patients who cannot tolerate buprenorphine and naloxone sublingual film or buprenorphine and naloxone sublingual tablet; for example, those patients who have been shown to be hypersensitive to naloxone. Medication should be prescribed in consideration of the frequency of visits. Provision of multiple refills is not advised early in treatment or without appropriate patient follow-up visits. 2.2 Patient Access to Naloxone for the Emergency Treatment of Opioid Overdose Discuss the availability of naloxone for the emergency treatment of opioid overdose with the patient and caregiver. Because patients being treated for opioid use disorder have the potential for relapse, putting them at risk for opioid overdose, strongly consider prescribing naloxone for the emergency treatment of opioid overdose, both when initiating and renewing treatment with buprenorphine sublingual tablet. Also consider prescribing naloxone if the patient has household members (including children) or other close contacts at risk for accidental ingestion or opioid overdose [see Warnings and Precautions (5.2)]. Advise patients and caregivers that naloxone may also be administered for a known or suspected overdose with buprenorphine sublingual tablet itself. Higher than normal doses and repeated administration of naloxone may be necessary due to the long duration of action of buprenorphine sublingual tablet and its...

Drug Interactions
7 DRUG INTERACTIONS Table 3 includes clinically significant drug interactions with buprenorphine. Table 3. Clinically Significant Drug Interactions Benzodiazepines or other Central Nervous System (CNS) Depressants Clinical Impact: Due to additive pharmacologic effects, the concomitant use of benzodiazepines or other CNS depressants, including alcohol, increases the risk of respiratory depression, profound sedation, coma, and death. Intervention: Cessation of benzodiazepines or other CNS depressants is preferred in most cases of concomitant use. In some cases, monitoring in a higher level of care for taper may be appropriate. In others, gradually tapering a patient off of a prescribed benzodiazepine or CNS depressant or decreasing to the lowest effective dose may be appropriate. Before co-prescribing benzodiazepines for anxiety or insomnia, ensure that patients are appropriately diagnosed and consider alternative medications and non-pharmacologic treatments [see Warnings and Precautions (5.2, 5.3)]. If concomitant use is warranted, strongly consider prescribing naloxone for the emergency treatment of opioid overdose, as is recommended for all patients in treatment for opioid use disorder [see Warnings and Precautions (5.2)]. Examples: Alcohol, benzodiazepines and other sedatives/hypnotics, anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, and other opioids. Inhibitors of CYP3A4 Clinical Impact: The concomitant use of buprenorphine and CYP3A4 inhibitors can increase the plasma concentration of buprenorphine, resulting in increased or prolonged opioid effects, particularly when an inhibitor is added after a stable dose of buprenorphine is achieved. After stopping a CYP3A4 inhibitor, as the effects of the inhibitor decline, the buprenorphine plasma concentration will decrease [see Clinical Pharmacology (12.3)] , potentially resulting in decreased opioid efficacy or a withdrawal syndrome in patients who had developed physical dependence to buprenorphine. Intervention: If concomitant use is necessary, consider dosage reduction of buprenorphine until stable drug effects are achieved. Monitor patients for respiratory depression and sedation at frequent intervals. If a CYP3A4 inhibitor is discontinued, consider increasing the buprenorphine dosage until stable drug effects are achieved. Monitor for signs of opioid withdrawal. Examples: Macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g. ketoconazole), protease inhibitors (e.g., ritonavir) CYP3A4 Inducers Clinical Impact: The concomitant use of buprenorphine and CYP3A4 inducers can decrease the plasma concentration of buprenorphine [see Clinical Pharmacology (12.3)] , potentially resulting in decreased efficacy or onset of a withdrawal syndrome in patients who have developed physical dependence to buprenorphine. After stopping a CYP3A4 inducer, as the effects of the inducer decline, the buprenorphine plasma concentration will increase [see Clinical...
Contraindications
4 CONTRAINDICATIONS Buprenorphine sublingual tablet is contraindicated in patients with a history of hypersensitivity to buprenorphine, as serious adverse reactions, including anaphylactic shock, have been reported [see Warnings and Precautions (5.9)]. Hypersensitivity to buprenorphine. ( 4 )
Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary The data on use of buprenorphine, the active ingredient in buprenorphine sublingual tablets, in pregnancy, are limited; however, these data do not indicate an increased risk of major malformations specifically due to buprenorphine exposure. There are limited data from randomized clinical trials in women maintained on buprenorphine that were not designed appropriately to assess the risk of major malformations [see Data]. Observational studies have reported on congenital malformations among buprenorphine‐exposed pregnancies, but were also not designed appropriately to assess the risk of congenital malformations specifically due to buprenorphine exposure [see Data]. Reproductive and developmental studies in rats and rabbits identified adverse events at clinically relevant and higher doses. Embryofetal death was observed in both rats and rabbits administered buprenorphine during the period of organogenesis at doses approximately 6 and 0.3 times, respectively, the human sublingual dose of 16 mg/day of buprenorphine. Pre- and post-natal development studies in rats demonstrated increased neonatal deaths at 0.3 times and above and dystocia at approximately 3 times the human sublingual dose of 16 mg/day of buprenorphine. No clear teratogenic effects were seen when buprenorphine was administered during organogenesis with a range of doses equivalent to or greater than the human sublingual dose of 16 mg/day of buprenorphine. However, increases in skeletal abnormalities were noted in rats and rabbits administered buprenorphine daily during organogenesis at doses approximately 0.6 times and approximately equal to the human sublingual dose of 16 mg/day of buprenorphine, respectively. In a few studies, some events such as acephalus and omphalocele were also observed but these findings were not clearly treatment-related [see Data] . Based on animal data, advice pregnant women of the potential risk to a fetus. The estimated background risks of major birth...
Overdosage
10 OVERDOSAGE Clinical Presentation The manifestations of acute overdose include pinpoint pupils, sedation, hypotension, hypoglycemia, respiratory depression, and death. Treatment of Overdose In the event of overdose, the respiratory and cardiac status of the patient should be monitored carefully. When respiratory or cardiac functions are depressed, primary attention should be given to the re-establishment of adequate respiratory exchange through provision of a patent airway and institution of assisted or controlled ventilation. Oxygen, IV fluids, vasopressors, and other supportive measures should be employed as indicated. In the case of overdose, the primary management should be the re-establishment of adequate ventilation with mechanical assistance of respiration, if required. Naloxone may be of value for the management of buprenorphine overdose. Higher than normal doses and repeated administration may be necessary. The long duration of action of buprenorphine sublingual tablet should be taken into consideration when determining the length of treatment and medical surveillance needed to reverse the effects of an overdose. Insufficient duration of monitoring may put patients at risk.
