Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation program who recognize how challenging and difficult 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 often 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 must only be done under close supervision at a drug rehab facility which has experience in handling this type of detoxification, and where the person can receive further rehabilitation services to deal with all addiction issues.
