Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehab facility who realize how difficult and challenging methadone detox can be. Methadone detox 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 alleviate 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 center which has experience in dealing with this type of detox, and where the individual can receive additional recovery services to deal with all addiction issues.
