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