Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug treatment facility who understand how challenging and difficult methadone detoxification can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab center which has practical experience in dealing with this type of detoxification, and where the individual can receive additional rehabilitation services to deal with all addiction issues.
