Medical Treatment for Substance Use Disorder (SUD)

Comprehensive Treatment Approach

  • The American Medical Association recommends that all individuals at risk for or with HIV should receive screening, diagnosis, and treatment for SUDs, with a strong evidence base 1
  • Early identification of substance use problems is critical, using standardized screening tools in healthcare settings, as recommended by the American Academy of Child and Adolescent Psychiatry 3
  • Screening, Brief Intervention, and Referral to Treatment (SBIRT) should be implemented in various settings including primary care, with moderate evidence supporting its effectiveness 3

Pharmacotherapy Options

  • The American College of Physicians recommends FDA-approved medications for specific SUDs, including methadone, buprenorphine, and naltrexone for opioid use disorder, with high evidence quality 2, 4
  • The American College of Physicians also recommends naltrexone and acamprosate for alcohol use disorder, with moderate evidence quality 2, 4

Behavioral Therapies

  • The American Psychological Association recommends evidence-based behavioral approaches, including cognitive-behavioral therapy (CBT), contingency management, and motivational enhancement therapy, with strong evidence supporting their effectiveness 2, 5, 6
  • Combined pharmacotherapy with CBT shows greater efficacy than usual care with pharmacotherapy, as reported by the JAMA network open, with high evidence quality 5, 7

Substance-Specific Approaches

  • The American Society of Addiction Medicine recommends medication-assisted treatment (MAT) as the gold standard for opioid use disorder, combining medications with behavioral therapies, with high evidence quality 2, 4
  • The American Society of Addiction Medicine also recommends first-line pharmacotherapy, including naltrexone and acamprosate, for alcohol use disorder, with moderate evidence quality 2, 4

Special Considerations

  • The National Institute of Mental Health recommends integrated treatment for co-occurring mental health disorders and SUDs, with moderate evidence supporting its effectiveness 1
  • The Centers for Disease Control and Prevention recommends harm reduction services, including naloxone distribution, safe injection education, and referral to syringe service programs, with strong evidence supporting their effectiveness 1, 2

Emerging Approaches

  • The National Institute on Drug Abuse recommends digital interventions for prevention, early intervention, and treatment, with emerging evidence supporting their effectiveness 3
  • The American Academy of Neurology recommends neuromodulation techniques, such as transcranial magnetic stimulation, as adjunctive treatments, with emerging evidence supporting their effectiveness 6

Common Pitfalls to Avoid

  • The American Medical Association recommends avoiding withholding SUD medications due to concerns about drug interactions with HIV or HCV treatments, with strong evidence supporting their safety 1
  • The American Academy of Child and Adolescent Psychiatry recommends avoiding focusing solely on abstinence rather than harm reduction approaches, with moderate evidence supporting the importance of harm reduction 1, 3
