Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehabilitation 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 users 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 must only be done under strict supervision at a drug rehabilitation facility which has experience in handling this type of detoxification, and where the person can receive additional treatment services to address all addiction issues.
