Methadone detoxification is a course of action which should be overseen by substance abuse professionals within a drug rehab program who recognize how difficult and challenging methadone detox can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users 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 detox must only be done under strict supervision at a drug rehab center which has experience in dealing with this type of detoxification, and where the person can receive further treatment services to handle all addiction issues.
