Generic Name and Formulations:
Buprenorphine (as HCl), naloxone (as HCl dihydrate); 2mg/0.5mg, 4mg/1mg, 8mg/2mg, 12mg/3mg; sublingual films; lime-flavor.
Indications for SUBOXONE:
Treatment of opioid dependence, as part of a complete treatment plan to include counseling and psychosocial support.
Do not cut, chew or swallow. Avoid food or drinks until film dissolves. Give by sublingual (SL: under the tongue) or buccal (inside of cheek) administration. Place additional films sublingually or buccally on opposite side from the first film if needed; should minimize overlapping. Start when clear signs of withdrawal occur; individualize based on type and degree of opioid dependence. Supervised induction (use SL route): Day 1: initially 2mg/0.5mg or 4mg/1mg; may increase in increments of buprenorphine 2mg or 4mg at 2-hr intervals, up to 8mg/2mg based on response; Day 2: a single dose up to 16mg/4mg. Dependent on heroin or short-acting opioids: initiate induction with either Suboxone film or buprenorphine monotherapy (SL tabs) at least 6hrs after last opioid dose. Dependent on methadone or long-acting opioids: initiate buprenorphine monotherapy (SL tabs) for induction, then transition to once daily Suboxone. Maintenance phase: (target dose): 16mg/4mg once daily; adjust in 2mg/0.5mg or 4mg/1mg increments/decrements; (usual range): 4mg/1mg–24mg/6mg once daily. Switching between buprenorphine or buprenorphine/naloxone tabs and Suboxone films: start on same dosage as previously; may need dose adjustments between products; monitor for over- or under-dosing. Switching between various Suboxone film strengths: systemic exposures may be different; monitor for over- or under-dosing. Hepatic impairment (severe): not recommended; (moderate): avoid use for induction. Concomitant use or discontinuation of CYP3A4 inhibitors or inducers: monitor closely and consider dose adjustments (see full labeling).
Risk of significant respiratory depression; monitor. Compromised respiratory function (eg, COPD, cor pulmonale, decreased respiratory reserve, hypoxia, hypercapnia, pre-existing respiratory depression). Abuse potential (monitor). Accidental exposure may cause fatal overdose (esp. in children). Adrenal insufficiency. Obtain LFTs at baseline then monitor periodically; evaluate if hepatic event is suspected. Opioid-naïve. Elevated CSF pressure (eg, head injury, intracranial lesions). Biliary tract dysfunction. Acute abdomen. CNS depression. Moderate and severe hepatic impairment. Drug abusers. Reevaluate periodically. Avoid abrupt cessation. Elderly. Labor & delivery: may need additional analgesia. Pregnancy/postpartum: may need dose adjustments; monitor closely for withdrawal. Potential neonatal opioid withdrawal syndrome during prolonged use. Nursing mothers: monitor infants.
Opioid (partial agonist-antagonist) + opioid antagonist.
Increased risk of hypotension, respiratory depression, sedation with benzodiazepines or other CNS depressants (eg, non-benzodiazepine sedatives/hypnotics, anxiolytics, general anesthetics, tranquilizers, muscle relaxants, antipsychotics, alcohol, other opioids); manage concomitant use as clinically appropriate and closely monitor. During or within 14 days of MAOIs: not recommended. Risk of serotonin syndrome with serotonergic drugs (eg, SSRIs, SNRIs, TCAs, triptans, 5-HT3 antagonists, mirtazapine, trazodone, tramadol, MAOIs, linezolid, IV methylene blue); monitor and discontinue if suspected. Concomitant NNRTIs (eg, efavirenz, nevirapine, etravirine, delavirdine) or PIs (eg, atazanavir with/without ritonavir): monitor and reduce Suboxone dose, if needed. Potentiated by CYP3A4 inhibitors (eg, macrolides, azole antifungals, protease inhibitors). Antagonized by CYP3A4 inducers (eg, rifampin, carbamazepine, phenytoin). May antagonize diuretics; monitor. Paralytic ileus may occur with anticholinergics.
Oral hypoesthesia, glossodynia, oral mucosal erythema, headache, nausea, vomiting, hyperhidrosis, constipation, withdrawal signs/symptoms, insomnia, pain, peripheral edema; respiratory depression, orthostatic hypotension, hepatitis, hypersensitivity reactions.
Renal, fecal (primary).
