What is the indication for Suboxone (buprenorphine/naloxone)?

Indication for Suboxone (Buprenorphine/Naloxone)

Suboxone is indicated for the treatment of opioid use disorder in patients aged 16 years and older, and should be prescribed as medication-assisted treatment combined with behavioral therapies to reduce illicit opioid use, prevent relapse, and improve patient outcomes. 1

Primary Indication

Suboxone (buprenorphine/naloxone combination) is FDA-approved specifically for opioid use disorder, defined by DSM-5 criteria as a problematic pattern of opioid use causing clinically significant impairment or distress with at least two diagnostic criteria present within a year. 1

Age Requirements

• Approved for patients 16 years and older 1
• Federal regulations generally prohibit methadone programs from admitting patients younger than 18 years, making buprenorphine particularly important for adolescent populations 1

Why Suboxone Over Buprenorphine Alone

The buprenorphine/naloxone combination (Suboxone) is preferred over buprenorphine alone (Subutex) for most patients because the naloxone component reduces misuse potential by precipitating withdrawal if the medication is crushed and injected, while having no clinically significant effect when taken sublingually as prescribed. 2, 3, 4

Exceptions Where Buprenorphine Alone May Be Preferred

• Pregnancy (use buprenorphine without naloxone) 1, 2
• Documented naloxone allergy 2
• Severe chronic pain requiring divided dosing 2

Treatment Framework

Evidence-Based Approach

Suboxone should be offered as medication-assisted treatment in combination with behavioral therapies, not as monotherapy. 1 This combination approach has been shown to:

• Reduce opioid misuse 1
• Increase retention in treatment 1
• Improve compliance after detoxification 1
• Prevent relapse more effectively than behavioral therapy alone 1

Target Dosing

• Therapeutic dose range: 8-16 mg daily 2
• Target dose for most patients: 16 mg daily 2
• The 4:1 ratio of buprenorphine to naloxone means a 16 mg dose contains 16 mg buprenorphine and 4 mg naloxone 3, 4

Clinical Context and Efficacy

Comparative Effectiveness

Buprenorphine maintenance therapy demonstrates clinical equivalence to methadone in retaining patients in treatment and reducing illicit opioid use. 1, 3 The CDC guidelines specifically recommend buprenorphine or methadone as first-line medication-assisted treatment, with moderate quality evidence supporting their superiority over non-medication approaches. 1

Mechanism of Action

Buprenorphine is a partial mu-opioid receptor agonist with high receptor affinity, which provides gentle stimulation of the opioid system to ameliorate withdrawal symptoms and reduce cravings without producing the intense euphoria of full agonists. 1, 2 This pharmacologic profile creates a ceiling effect on respiratory depression, improving safety compared to full agonists. 1

Important Clinical Caveats

Initiation Requirements

Critical pitfall to avoid: Suboxone must only be initiated when patients are in active opioid withdrawal to prevent precipitated withdrawal. 2 Required waiting periods include:

• Short-acting opioids (e.g., heroin): >12 hours since last use 2
• Extended-release formulations: >24 hours 2
• Methadone maintenance: >72 hours 2

Confirm withdrawal severity using the Clinical Opiate Withdrawal Scale (COWS) before initiating treatment. 2

Contraindications and Drug Interactions

• Concomitant use with QT-prolonging agents is contraindicated due to cardiac risk 1, 2
• Multiple drug interactions can cause serotonin syndrome, paralytic ileus, or reduced analgesic effect 1
• Avoid abrupt discontinuation in patients on long-term therapy 1

Special Populations and Situations

Adolescents and Young Adults

The American Academy of Pediatrics specifically advocates for increasing access to medication-assisted treatment for adolescent and young adult patients with severe opioid use disorders, recommending that pediatricians either offer buprenorphine treatment directly or arrange referrals. 1

Pregnant Patients

For pregnant women with opioid use disorder, medication-assisted therapy with buprenorphine without naloxone (not Suboxone) or methadone is associated with improved maternal outcomes and should be offered. 1

Patients with Chronic Pain

While the transdermal buprenorphine patch is FDA-approved for chronic pain, the sublingual buprenorphine/naloxone tablets can be prescribed off-label in divided doses (every 6-8 hours) for pain management. 1, 2 However, the primary indication for Suboxone specifically remains opioid use disorder treatment. 2

Perioperative Management

For patients on Suboxone maintenance requiring surgery, the decision to continue or hold should be individualized based on prescribed daily dose, indication for treatment (dependency vs. pain), risk of relapse, and expected post-surgical pain level. 1, 2 For acute pain management, continue the usual Suboxone dose and add short-acting opioid analgesics as needed for breakthrough pain. 2

Monitoring Requirements

Ongoing treatment requires:

• Regular urine drug testing to assess for continued illicit opioid use 2
• Reassessment using DSM-5 criteria at follow-up visits 2
• Hepatitis C and HIV screening as part of comprehensive care 2
• Coordination with behavioral health providers 1
