Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation program who understand how challenging and difficult methadone detoxification can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under strict supervision at a drug rehab facility which has experience in handling this type of detox, and where the person can receive further recovery services to handle all addiction issues.
