Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehab program who realize how difficult and challenging methadone detoxification can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab center which has practical experience in dealing with this type of detoxification, and where the individual can receive further rehabilitation services to handle all addiction issues.
