Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehab facility who understand how challenging and difficult methadone detox can be. Methadone detoxification is known to be far more serious 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 alleviate symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab facility which has experience in dealing with this type of detoxification, and where the person can receive further recovery services to address all addiction issues.
