Methadone detoxification is a process which must be overseen by addiction professionals within a drug rehab center who realize 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 frequently revert back to methadone to relieve 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 rehabilitation program which has experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to address all addiction issues.
