Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehab facility who realize how challenging and difficult methadone detoxification can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals 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 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 handle all addiction issues.
