Methadone detoxification is a course of action which should be supervised by addiction professionals within a drug rehab facility who understand how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and individuals typically 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 center which has experience in dealing with this type of detox, and where the person can receive additional treatment services to deal with all addiction issues.
