Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehab facility who realize how challenging and difficult methadone detoxification can be. Methadone detox is regarded to be far more severe 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 alleviate symptoms. This is why methadone detoxification must only be done under strict supervision at a drug rehab program which has experience in handling this type of detoxification, and where the individual can receive further treatment services to deal with all addiction issues.
