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