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