Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehabilitation center who understand how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should 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 treatment services to handle all addiction issues.
