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