Methadone detoxification is a process which should be overseen by drug addiction professionals within a drug treatment facility who realize how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox should only be done under close supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the person can receive further rehabilitation services to address all addiction issues.
