Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehabilitation program who recognize how challenging and difficult methadone detoxification can be. Methadone detoxification is known to be far more serious 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 detoxification should only be done under strict supervision at a drug rehab facility which has experience in handling this type of detox, and where the individual can receive additional treatment services to deal with all addiction issues.
