Methadone has been used safely and effectively for decades as one of the most studied treatments for opioid use disorder (OUD). It is a long-acting opioid agonist that relieves withdrawal symptoms, reduces cravings, and stabilizes brain chemistry without producing the rapid highs and lows of other opioids. Methadone is taken once daily in a structured, supervised setting, providing consistency and accountability for patients. This stability allows individuals to focus on counseling, employment, and rebuilding their lives with confidence.
