Methadone is a powerful medication with dual roles in pain management and opioid addiction treatment. Its effectiveness, particularly in reducing withdrawal symptoms and cravings in opioid use disorder, makes it a critical component of many treatment programs. However, due to its potential for abuse, addiction, and serious side effects, methadone must be used under strict medical supervision. Patients should follow all prescribed guidelines, report any adverse effects to their healthcare provider, and ensure the medication is stored and disposed of properly to prevent misuse.
