Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab facility who understand how challenging and difficult methadone detox can be. Methadone detox 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 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 program which has experience in handling this type of detoxification, and where the person can receive additional rehabilitation services to address all addiction issues.
