Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug treatment facility who understand how difficult and challenging methadone detox can be. Methadone detox is known to be far more serious 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 relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab center which has experience in handling this type of detoxification, and where the individual can receive further rehabilitation services to address all addiction issues.
