Methadone detoxification is a course of action which should be overseen by addiction professionals within a drug rehab program who understand how difficult and challenging methadone detox 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 alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab facility which has practical experience in dealing with this type of detox, and where the person can receive additional recovery services to address all addiction issues.
