Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation center who understand how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and individuals 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 detox must 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 deal with all addiction issues.
