Methadone detoxification is a course of action which should be supervised by substance abuse professionals within a drug rehab program who realize how difficult and challenging methadone detox can be. Methadone detoxification 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 alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab center which has experience in handling this type of detoxification, and where the individual can receive additional rehabilitation services to address all addiction issues.
