The stabilization phase involves adjusting the dosage based on individual needs by experienced prescribers, who must distinguish between toxicity and withdrawal symptoms. Long-term maintenance includes continuous monitoring, addressing any ongoing illicit drug use, providing comprehensive psychological and social support, and collaborating with specialists when necessary. The guide also outlines important aspects of safe prescribing, the conditions under which prescriptions may be suspended or discontinued, and critical safety measures related to high-risk periods like treatment initiation and release from incarceration, potential drug interactions, preventing diversion, and managing concurrent
