Methadone detoxification is a course of action which must be overseen by substance abuse 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 users frequently revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detox must only be done under strict supervision at a drug rehabilitation center which has experience in dealing with this type of detoxification, and where the person can receive additional treatment services to deal with all addiction issues.
