Methadone detoxification is a process which must be supervised by addiction professionals within a drug rehabilitation program who realize how difficult and challenging methadone detox can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab center which has experience in dealing with this type of detoxification, and where the individual can receive further recovery services to deal with all addiction issues.
