Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab program who recognize how challenging and difficult methadone detoxification can be. Methadone detox 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 ease symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab facility which has experience in handling this type of detoxification, and where the person can receive additional rehabilitation services to handle all addiction issues.
