Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehab program who recognize how difficult and challenging methadone detox can be. Methadone detoxification is regarded 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 detox 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 treatment services to address all addiction issues.
