Methadone detoxification is a course of action which must be overseen by substance abuse professionals within a drug treatment facility who understand how difficult and challenging methadone detox can be. Methadone detoxification 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 relieve 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 additional rehabilitation services to deal with all addiction issues.
