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 severe in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox must only be done under close supervision at a drug rehabilitation facility which has practical experience in dealing with this type of detox, and where the individual can receive additional rehabilitation services to address all addiction issues.
