Methadone detoxification is a course of action which must be supervised by addiction professionals within a drug rehab program who understand how challenging and difficult methadone detox can be. Methadone detox is known to be far more severe 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 alleviate symptoms. This is why methadone detox should only be done under close supervision at a drug rehab program which has practical experience in handling this type of detoxification, and where the person can receive additional recovery services to handle all addiction issues.
