Buprenorphine and Naloxone

Clinical summary

Indications and usage Buprenorphine and naloxone sublingual tablets are indicated for maintenance treatment of opioid dependence. Buprenorphine and naloxone sublingual tablets should be used as part of a complete treatment plan that includes counseling and psychosocial support. Standard dosing Administer buprenorphine and naloxone sublingual tablet sublingually as a single daily dose. ( 2.1 ) Strongly consider recommending or prescribing an opioid overdose reversal agent (e.g., naloxone, nalmefene) at the time buprenorphine and naloxone sublingual tablet are 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 tablets should be undertaken when objective and clear signs of withdrawal are evident. After induction, doses of buprenorphine and naloxone sublingual tablets should be progressively adjusted to a level that holds the patient in treatment and suppresses opioid withdrawal signs and symptoms ( 2.3 ) The maintenance dose of buprenorphine and naloxone sublingual tablets is generally in the range of 4 mg/1 mg to 24 mg/6 mg per day and should be based on clinical response. ( 2.3 ) Administer buprenorphine and naloxone sublingual tablets as directed in the Full Prescribing Information. ( 2.3 , 2.4 ) When discontinuing treatment, gradually taper to avoid signs and symptoms of withdrawal. ( 2.7 ) Contraindications Buprenorphine and naloxone sublingual tablet is contraindicated in patients with a history of hypersensitivity to buprenorphine or naloxone as serious adverse reactions, including anaphylactic shock, have been reported [see Warnings and Precautions (5.9) ] . Key warnings Addiction, Abuse, and Misuse: Buprenorphine can be abused in a similar manner to other opioids. Clinical monitoring appropriate to the patient's level of stability is essential. Monitor patients for conditions indicative of diversion or progression of opioid dependence and addictive behaviors. Multiple refills should not be prescribed early in treatment or without appropriate patient follow-up visits. ( 5.1 ) Respiratory Depression: Life-threatening respiratory depression and death have occurred in association with buprenorphine use. Warn patients of the potential danger of self-administration of benzodiazepine or other CNS depressants while under treatment with buprenorphine and naloxone sublingual tablets. ( 5.2 , 5.3 ). Unintentional Pediatric Exposure: Store buprenorphine and naloxone sublingual tablets safely out of the sight and reach of children. Buprenorphine can cause severe, possibly fatal, respiratory depression in children. ( 5.4 ) Neonatal Opioid Withdrawal Syndrome: Neonatal opioid withdrawal syndrome (NOWS) is an expected and treatable outcome of prolonged use of opioids during pregnancy. ( 5.5 ) Adrenal Insufficiency: If diagnosed, treat with physiologic replacement of corticosteroids, and wean patient off of the opioid. ( 5.6 ) Risk of Opioid Withdrawal with Abrupt Discontinuation: If treatment is temporarily interrupted or discontinued, monitor patients for withdrawal and treat appropriately. ( 5.7 ) Risk of Hepatitis, Hepatic Events: Monitor liver function tests prior to initiation and during treatment and evaluate suspected hepatic events. ( 5.8 ) Precipitation of Opioid Withdrawal Signs and Symptoms: An opioid withdrawal syndrome is likely to occur with parenteral misuse of buprenorphine and naloxone sublingual tablets by individuals physically dependent on full opioid agonists, or by sublingual administration before the agonist effects of other opioids have subsided. ( 5.10 ) Risk of Overdose in Opioid-Naïve Patients: Buprenorphine and naloxone sublingual tablet is not appropriate as an analgesic. There have been reported deaths of opioid naïve individuals who received a 2 mg sublingual dose. ( 5.11 ) Drug interactions Table 3 Includes clinically significant drug interactions with buprenorphine and naloxone sublingual tablets. Table 3. Clinically Significant Drug Interactions with Buprenorphine and Naloxone Sublingual Tablets 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, can increase the risk of hypotension, 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 other 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-p
