Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation program who understand 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 individuals frequently revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab program which has experience in dealing with this type of detox, and where the individual can receive further rehabilitation services to deal with all addiction issues.
