Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation center who recognize how difficult and challenging methadone detox can be. Methadone detox 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 relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification should only be done under strict supervision at a drug rehab program which has practical experience in handling this type of detox, and where the person can receive further rehabilitation services to deal with all addiction issues.
