Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehabilitation program 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 alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab facility which has experience in handling this type of detoxification, and where the person can receive additional recovery services to deal with all addiction issues.
