Methadone Treatment

What is Methadone

Methadone is a long-acting opioid agonist medication used in medication-assisted treatment (MAT) for opioid use disorder. It is taken orally once daily in opioid treatment programs (OTPs) that provide comprehensive treatment and monitoring. Methadone occupies opioid receptors, preventing withdrawal and cravings without inducing euphoria. It allows patients to stabilize, improve functioning, and reduce illicit opioid use.

Societal perspectives on methadone are mixed. Some view it negatively as simply replacing one opioid with another. However, research shows MAT with methadone is associated with reduced mortality, crime, and transmission of HIV/HCV compared to no treatment. It enables patients to hold jobs, secure housing, and reconnect with families. Still, stigma remains a barrier. Education is needed, so society understands MAT is legitimate medical treatment, not “substituting one addiction for another.”

Methadone Distribution

OTP programs providing methadone must follow strict federal and state regulations to prevent misuse and diversion:

  • Urine testing: Patients undergo randomized urine drug screens at least 8 times in the first year to ensure compliance.
  • Take-home doses: Limited to a 1-day supply for the first 2 weeks of treatment, with gradual increases in take-homes based on time in treatment and progress.
  • Monitoring: Interprofessional teams of doctors, counselors, and nurses oversee dosing, urine screens, counseling, and coordination of care.
  • Prescription monitoring: Clinicians check the state prescription drug monitoring program (PDMP) when determining dosage, due to risks like QTc prolongation.

In New Hampshire, methadone is a Schedule II controlled substance requiring a prescription. In Merrimack County, methadone accounted for 22% of OTP admissions in 2020.

Methadone Treatment Effectiveness Research

Methadone has been used to treat opioid addiction since 1947. Studies show it is an effective MAT option.

Evidence for Effectiveness

Multiple studies demonstrate methadone reduces opioid use, infectious disease transmission, criminal activity, and mortality compared to no treatment:

  • 33% fewer opioid-positive drug tests for methadone patients
  • 4.44 times more likely to stay in treatment vs. non-medication treatments
  • Retention in treatment reduces overdose risk and improves employment

Major Drawbacks

However, methadone does carry risks requiring careful management:

  • Potential for misuse/diversion requires OTP structure
  • Sudden discontinuation can cause severe withdrawal
  • Can prolong the QTc interval on EKGs, causing cardiac issues
  • Still an opioid, so can cause respiratory depression and overdose, especially when combined with other substances

Comparison to Other Medications

Research shows methadone and buprenorphine are equally effective for reducing illicit opioid use and retaining people in treatment.

Methadone is beneficial but also has risks, requiring strict oversight.
