Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehabilitation center who understand how difficult and challenging methadone detoxification can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals 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 strict supervision at a drug rehab facility which has experience in dealing with this type of detox, and where the person can receive additional treatment services to handle all addiction issues.
