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