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