Commentary highlights the need for rapid methadone initiation to improve outcomes in opioid use disorder, suggesting that current practices must change.
In a drug landscape dominated by the highly potent synthetic opioid fentanyl, traditional methadone initiation protocols increasingly fail people with opioid use disorder (OUD). While "low" initial dose selection and "slow" dose adjustment rates reduce risk for methadone-associated toxicity, they also result in weeks to months of unrelieved withdrawal symptoms and cravings, especially for people with high opioid tolerance from routine fentanyl use. For this growing population, "low-and-slow" forces a choice between 3 poor options: suffer weeks to months of withdrawal, self-manage withdrawal through non-prescribed substance use, or give up on treatment. Our commentary combines a Peer Support Specialist's lived experiences with methadone initiation and evidence from the peer-reviewed literature to illustrate this problem and the role of one potential solution: rapid methadone initiation (RMI), defined here as reaching a methadone dose of 80 mg or more within the first 7 days of treatment. For appropriately selected patients, RMI is associated with positive outcomes, including improved patient satisfaction, reduced readmission rates, and increased retention in care. Though regulations permit and growing evidence supports RMI, adoption remains limited. Our commentary, therefore, concludes by sharing frameworks to support providers in implementing RMI as a potential treatment option for people with OUD across applicable care settings. Methadone's life-saving potential depends on dosing that matches the physiological reality of fentanyl use. Collectively, addiction clinicians define the community standard of care. In the face of a transformed drug landscape, it is time for that standard to evolve to ensure that the option for rapid and effective relief becomes the rule, rather than the exception.
