Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab center who realize how difficult and challenging methadone detox can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals frequently 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 strict supervision at a drug rehab center which has experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to handle all addiction issues.
