Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehab program who realize how difficult and challenging methadone detoxification can be. Methadone detoxification is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to ease 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 facility which has practical experience in dealing with this type of detoxification, and where the individual can receive further recovery services to address all addiction issues.
