Methadone detoxification is a course of action which should be overseen by addiction professionals within a drug rehab program who recognize how difficult and challenging methadone detoxification can be. Methadone detoxification is known 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 relieve symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehab program which has experience in handling this type of detox, and where the person can receive further rehabilitation services to deal with all addiction issues.
